Product Description 2.1 General Description The Tsunami licensed radios provide high capacity transmission and operational convenience in a digital communications network. These Tsunami radios provide 1000BaseF intelligent bridging between two fixed coordinated locations. Because each owner controls the operation of the link, there is no reliance on any outside services. Tsunami radio operators are able to operate whenever needed, and to be in control of their own network. The Tsunami offers two primary benefits:

v CONVENIENCE v CAPABILITY to install and operate with a user license Easy coordinated in the USA. (Other countries may also require a user license and/or frequency coordination). Full transparent Fast Ethernet connections with no throughput reduction over any line-of-sight distance (within legal limits of government regulation) Tsunami radios are ISO Layer 2 Data Link Layer (use MAC address for filtering) devices where they provide their full stated throughput. At level 2 (bridges) or 3/4 (routers) where hardware plays the major part, the most common tester is the SmartBits 200 product from NetCom Systems. At Application Layer 7, you will see less than 40% throughput from the maximum capacity measured with SmartBits due to the increased protocol/software overhead at that level. Layer 7 can be tested with software such as Ganymede's Chariot or Qcheck product (www.qcheck.net/index.html). Use Qcheck (or equivalent), do NOT use PING for throughput testing (www.qcheck.net/whyqcheck.html)!

As an example: testing copper CAT5e cable with SmartBits will test 100% throughput (let's say you can send/receive a full 100Mbps). At Layer 7 you will be transferring bits at the 100Mbps rate, but approximately only 45Mbps of user data will transfer (Ethernet has a high overhead of bytes added to each data packet frame each time you go up a layer). The advantage is the more complex overhead makes the data virtually resilient to corruption and minor errors (i.e. collisions), its easy to reroute and the network can use inexpensive plug/play devices like hubs/switches instead of multiplexers as used in the telco industry (i.e. LYNX T1/E1/DS3 radios) Western Multiplex tests for stated throughput at Layer 2/3 where bridges are defined. At layer 7

(application layer), you may see less than 50% or more depending on the other traffic that may be on the LAN as this layer is more dependent on the type of data being sent (it does not matter if it's wire, fiber or any Ethernet bridge -wired or wireless). Another way to look at it: the model 31145 12Mbps

(10Mbps 10BaseT+T1/E1 wayside) bridge will test the same as a piece of CAT5e Ethernet cable.

GND RSL This is a grounding post to connect to earth ground. This is a test point (BNC connector) that relates to the Received Signal Level (RSL). The voltage is measured with a voltmeter (using the GND test point for reference) which corresponds to the actual power level of the incoming received signal. This is a test point which corresponds to the output transmit power of the radio. The voltage is measured with a voltmeter (using the GND test point for reference) which corresponds to the actual power level of the outgoing signal. This measurement is used during installation, maintenance and troubleshooting

. This voltage only applies to the near-end and does not allow measurement of the far-end output transmit power, even when the DISPLAY FAR END button is pressed. There is a receptacle on the front panel to the right of the LOCAL TX PWR test point which is an installation adjustment allowing the output transmit power to be increased or decreased within the radio's specified limits. Using a small screwdriver, this adjustment is used to set the output power of the transmitter, in accordance to the path planning. The Tsunami system requires professional installation. Transmitted output power limits may apply when using this radio. Consult FCC, IC, Western Multiplex or other regulatory authorities for limits which may apply. See Section 3.13.1 for details on setting output power. Do not adjust output power above factory settings.

end radio. When pressed and held, the alarm and status LEDs correspond to the far-end radios status. This can be used for installation, maintenance and troubleshooting. When the LED on this switch is flashing, no far-end information is available. This typically indicates that there is no link between near-end and far-end radios.

Use LDF4-50, LMR-400 or equivalent up to 100 meters (300 ft.) Use LDF4.5-50, LMR-600 or equivalent up to 300 meters (1000 ft.)

. DATA CONNECTION The connection for the Gigabit Ethernet interface that carries the signals in and out of the radio is an SC type 1000BaseF fiber connection. DC POWER CONNECTION The input accepts positive or negative DC power at any voltage between 37 and 63 Volts. OPTIONAL CONNECTIONS There are several connections that are not required for operation, but provide additional facilities to the user. EOW This connection is used to access the electronic orderwire function. This is a facility for "telephone" style service from one radio to another. A standard electronic telephone [one with a handset and DTMF (push-button tone) dialing] plugs into this connector. The user can dial the orderwire address of the far-end radio (or any radio in the Tsunami network) to establish telephone communication between sites. This communication does not interrupt or interfere with the other radio communications. The radio link must be operational to use this facility. The orderwire feature can be very useful for installation, maintenance and troubleshooting. VF This connector is used to link two Tsunami radios at a repeater site for Orderwire operation. This would allow orderwire "telephone" calls to and from any point in the Tsunami network. The Tsunami orderwire circuit can also be connected to other existing orderwire networks. See Section 3.14.1 for details. ALARM This connector is used for monitoring alarms electrically. The Form C relays can be connected to other transmission equipment for monitoring alarm status locally or remotely. DIAG This is a serial interface port (RS-232) to the Tsunami radio. This port provides configuration and maintenance information about the Tsunami radio(s) to a SECTION 2: PRODUCT DESCRIPTION PAGE 2-11 I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 connected computer or terminal. See section on TELNET session in this manual. AUX DATA This is a serial interface port (RS-232, 9600 baud) which allows the user to connect auxiliary serial data from one point in the radio network to another. It can be used for separate data connection for serial devices. 100Base NMS This is an Ethernet connection for access to the Tsunami NMS (SNMP or HTML). See section 4.11 for more detail for operation. T1 This is a wayside data channel for T1 (DS-1) interface of auxiliary traffic (27400-51 Models).

Installation & Adjustments 3.1 Shipping Container The equipment is shipped in boxes unless ordered as an integrated system and configured at the factory, in which case the equipment may be racked and shipped in a crate. The equipment is packaged so as to prevent damage in transit. The boxes should be left intact and sheltered until arrival at the installation site. If the shipping container shows signs of damage, the transportation company should be notified immediately. Extra care and inspection of the contents is advised immediately upon receipt. It is recommended that all the packaging materials be retained. In the unlikely event that the equipment must be returned to the factory, use the original packing materials for return shipment. The original packaging materials are also recommended for transporting the equipment from location to location. Inside the primary shipping containers, internal boxes may contain other items. These boxes should also be saved for future use. Also, save the Tsunami radio test data sheet that is provided. The test data sheet can be placed where the Tsunami terminal will be installed for future quick reference. All Tsunami units are individually tested and the actual measured performance recorded on the Factory Test Data Sheet. You will find this information to be of use during installation, troubleshooting and maintenance. A set of quick installation instructions is also provided which can be useful for easy reference during installation.

This section briefly describes the following:

- Site selection

- Line-of-Sight and Path Clearance determination

- Anticipated RSL calculation

- Fade margin calculation

- Availability calculation

- Frequency plan determination

- Power supply planning

- Antenna (and accessories) purchase Only directional antennas should be used with Tsunami radios. These are typically flat panel or solid parabolic antennas. Western Multiplex recommends a maximum beamwidth of 10 degrees for directional systems. 3.3.1 Site Selection Requirements The radio site must have:

- access to the appropriate power

- close proximity to the telephone or computer system you wish to interconnect

- line-of-sight to the other radio location with adequate clearance

- location for mounting the antenna SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-3 I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 3.3.2 Line-of-Sight and Path Clearance Guidelines The Tsunami radios will not operate properly unless they have line-of-sight between their corresponding antennas. The Tsunami radio transmission will not pass through trees or other obstacles. Factors to consider include:

- Earth curvature

- Future growth of trees

- Height of buildings In addition to the line-of-sight requirement, a well-engineered path will also have additional path clearance to allow for signal loss due to partial obstructions, atmospheric ducting and ground reflections. To maximize radio reception, 0.6 times the first Fresnel zone should be calculated and this distance added to the path clearance (in addition to trees or buildings). PAGE 3-4 SECTION 3: INSTALLATION & ADJUSTMENTS I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 3.3.3 RSL Calculation and Link Budget The received signal level (RSL) can be estimated using the following formula:

RSL (dBm) = Pout - FL1+ G1 + G2 - FL2 - Lp where: Pout is the transmitter output power (in dBm) FL1 is the feeder loss of the transmit side (in dB) G1 is the gain of the transmit antenna (in dB) G2 is the gain of the receive antenna (in dB) FL2 is the feeder loss of the receive side (in dB) Lp is the Path loss, defined by:

Lp (dB) = 96.6 + 20 log10F + 20 log10D where: F = Frequency in GHz (2.4 or 5.8) D = Distance of path in miles This link budget is very important for determining any potential problems during installation. If you have calculated the expected RSL, you can see if it has been achieved during installation, and troubleshoot if necessary. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-5 I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 3.3.4 Fade Margin Calculation The fade margin is the difference between the actual received signal and the radios threshold. Using the formula provided in Section 3.3.3, the anticipated RSL can be calculated. Compare this RSL to the specified threshold of the Tsunami radio (shown in Section 2.2) and calculate the fade margin as the difference between the two signal levels. 3.3.5 Availability Calculation Availability of the microwave path is a measure of the percent of the time that the link will operate without producing an excessive BER due to multipath fading. In the absence of direct interference, availability is affected by the following:

- Path length

- Fade margin

- Frequency (5.8 GHz in the case of these Tsunami radios)

- Terrain (smooth, average, mountainous)

- Climate (dry, temperate, hot/humid) Depending on the type of traffic carried over the link, the system designer may wish to design for a specific availability. For example, if the data or voice traffic that is carried by the radio is critical then it may be designed for a very high availability (e.g. 99.999% or 5.3 minutes of outage per year). To improve availability, for example, the fade margin can be increased by making the path shorter, or by using higher gain antennas. 1.5'

The Tsunami can be powered from a DC battery system, or from a solar or generator power plant, usually with battery reserves. Typically either a positive or negative 48 volt supply is used. For DC, be sure the cable is of sufficient gauge to carry the necessary current and it is less than three (3) meters (9.75 feet) in length. Before installing the radio, plan for the continuous power consumption needs in accordance with the specifications given in Section 2.2 of this manual. It is also wise to plan for backup power for critical communication circuits (including the Tsunami radio). Backup power allows the radios and associated equipment to continue operation when primary power is interrupted. 3.3.7 Antenna Planning Using path planning mathematics, proper antenna size can be determined which will yield the desired path performance. In general, the larger the antenna that is used with the Tsunami radio, the better the link will perform. Larger antennas have narrower beamwidth and higher gain, which will yield better link performance (higher fade margin, better availability) and improve immunity to interference (due to the smaller beamwidths). However, larger antennas are more costly to purchase and install than smaller antennas, in some cases requiring special equipment for installation. All of these factors should be taken into consideration when selecting antennas. In areas where transmitted output power restrictions apply, the use of larger antennas will maintain the benefit of narrow beamwidths and receive gain. However, output power may need to be reduced to meet regulations. (See Section 3.13.1) Prior to installation, the specific antenna location and mounting should be determined. This advanced planning also yields the transmission line requirements. Only dual-band/dual-polarized directional antennas can be used with these Tsunami radios.

- Phillips (cross tip) screwdrivers (for 19-inch rack mounting and attachment of brackets)

- Small blade standard screwdriver (for power supply connector and RF output power adjust)

- Soldering iron (if using any D-type connectors)

- Wire strippers (for removing insulation from power supply and other wiring)

- Wire crimpers (if using any RJ-style connectors that are not pre-made)

- Digital Voltmeter (to measure RSL, Tx output power, Alarms) The following tools are recommended for the installation of the Tsunami radios:

- RF power meter (to measure transmitter output power)

- Cellular phone or two-way radio (for talking with far-end crew and tower crew)

- Bit Error Rate test set (to test link after installation)

- Computer (for NMS access with 10BaseT interface and cable)

- Touch-tone Telephone* (to test orderwire circuits and for communication with far-end) Additional tools will likely be needed for antenna and transmission line installation and antenna alignment. Consult Sections 3.8 through 3.10 of this manual for more details.

Blank rack-mounting spaces above and below the Tsunami are recommended, especially if the surrounding equipment dissipates a considerable amount of heat. The Tsunami radio may be set up for mounting with the front edge projecting from the front face of a standard 19-inch rack using the rack mounting brackets enclosed with the screws in the Accessory Kit

(4 per bracket). The rack mounting brackets may be reversed, in order to install for flush or cabinet mounting if preferred. Depending on rack configuration, it may be necessary to remove the four adhesive backed rubber feet on the bottom of the unit. The Tsunami radio has internal fans which intake and exhaust on the left and right sides of the chassis. When rack mounting, it is important to leave a small gap between the outer edges of the radio and the inside edge of the rack. The Tsunami radio may alternatively be placed on a table or shelf attached to a wall. Because of the low weight of the Tsunami, any mounting option other than rack mounting will be less secure. The ODU is mounted on a substantial mounting pole (minimum 2.5 inches) to accommodate the supplied mounting bracket.

As soon as power is applied, the equipment will be operational. This means that there can be up to 1W of RF power present at the antenna port. The antenna port should be terminated before power is applied. Power is connected using the DC power plug contained in the Accessory Kit. Use Table 3-B or 3-C along with the associated diagram of Figure 3-3 or 3-4 to connect the DC power cables. For example, for a negative DC power input, use Table 3-B and Figure 3-4.

The recommended minimum current rating of external fuses and cables is 5 Amps. The Tsunami radios consume less than 4 Amps at 48V. Be sure the DC power cable is less than 3 meters (9.75 feet) in length. Each Tsunami terminal should be externally fused separately with a 8 Amp maximum fuse. The DC power cable must be less than three (3) meters in length. If using negative power, connect the negative voltage to pins 1 or 6. Connect the ground return connection to pins 3 or 4. See Figure 3-3. If using positive power, connect the positive voltage to pins 3 or 4. Connect the ground return connection to pins 1 or 6. See Figure 3-4. The ground connection is available at pins 2 and 5. Either pin may be used to ground the return side of the power supply. Do not ground both sides of the power supply. Proper grounding, either through the chassis and/or the power supply, can be very important for protection from lightning. A grounding screw hole is provided on the rear panel. The ground connection may be left floating if the power supply is referenced to ground externally and to avoid ground loops in some configurations. However, this may not provide adequate grounding for lightning protection. Use a DVM (digital voltmeter) to verify voltage and polarity on the DC power plug. Do not connect the DC power plug to the rear of the Tsunami terminal until a load is connected to the antenna port (either an RF pad, or an RF cable and antenna).

Installers should contact the manufacturer for applicable antenna gain and type restrictions to ensure compliance. The antenna installation consists of permanently mounting the antenna and then attaching the ODU mounting plate and then the ODU itself to the mount. The antenna and ODU assembly must be mounted outdoors on a tower, building roof, or other location that provides line-of-sight path clearance to the far-end location. In general, antennas smaller than 1.5 feet diameter are not recommended for urban. Antennas should be ordered with the suitable mounting kit specific to the site requirements. The antenna must be very rigidly mounted, with adequate room for azimuth and elevation adjustment from the rear. The antenna polarization must be the same at both ends of the link, either vertical or horizontal. The mounting kit includes the details on how to mount and adjust azimuth and tilt. Here, the details on how to mount the adapter plate and ODU are described. In general, antenna mountings require a support pipe to which upper and lower support brackets are attached with U bolts. The antenna and optional elevation and azimuth adjustment rods are then mounted onto the support brackets. The whole structure must be adequately grounded for lightning protection. The antenna system must always be installed according to the manufacturers instructions. Unless special test equipment is available, two operating Tsunami radios are required to align the antennas. The antenna is coarse aligned using visual sighting and then fine aligned using the receive signal level (RSL) voltage of the Tsunami. See figure 3-8. The RSL voltage reading can still be used to peak antennas even if the radios have not synchronized, however far-end RSL cannot be measured from the near-end terminal until radios are synchronized.

After attaching the mounting plate, use the antenna in either the horizontal or vertical polarization position (remember, both ends of the link MUST use the same polarization). Note: the A and B feed coax cables must be used for horizontal or vertical polarization with the ODU. After mounting the antenna, attach the dual coax cables that connects the ODU with the IDU.

Then point it at a heading marker obtained using a compass/GPS (magnetic corrected) back-bearing from an adjacent location, (ideally, 100 feet or more away from the antenna). If a heading marker cannot be set sufficiently far away (for example when on a city building roof or looking through a window) then a rough azimuth setting can be obtained by sighting along the antenna feed. It should be verified that both antennas are on the same polarization by using the manufacturers instructions. Otherwise the RSL will be approximately 25 to 30 dB below the calculated level. Most antennas will also need fine alignment obtained using an operating link because it is very important to maximize the receive RF signal level at each end of the radio link. Read Section 3.7 before applying DC power to the Tsunami radio. Once the coarse alignment has been set-up at both ends, then the link can be powered and some level of reliable communication established. The voltage at the Tsunami ODU RSL test point (BNC connector) should be measured with a DVM to determine the relative receive RF signal level. For the fine alignment, adjusting first the azimuth and then the elevation of the local antenna will maximize the RSL voltage. Then, the far antenna is aligned in the same way, using the RSL voltage of its local Tsunami radio ODU. When aligning antennas it may be convenient to allow direct visiblity to the technicians aligning the antenna. An orderwire telephone will provide end-to-end voice communications once radios are synchronized. Synchronization usually can be accomplished by coarse alignment only. After synchronization, the orderwire phones can be used to communicate between radio sites for antenna fine alignment. The phone interconnect cable can be extended to the antenna when desired. The larger the antenna size, the more critical alignment becomes: for example, with a 2 foot dish, the antenna can be moved 3 degrees off the correct heading before the receive signal level drops by 3 dB. This compares with a 6-foot dish which may only be moved 1 degree for the same degradation. The graph shown in Figure 3-8 shows the typical variation of RSL voltage as the receive signal level is increased from threshold to a higher level. There is some variation between Tsunami receivers, but an approximate estimate of the potential RSL value may be made using this figure. Use the Factory Test Data Sheet shipped with your Tsunami terminal to obtain the best estimate of your RSL.

A link budget calculation should be made to calculate the anticipated RSL as described in Section 3.3.3. During anomalous propagation conditions, the RSL may fade but will not increase up more than 10 dB (except in unusual very long paths which may fade up by 15 dB). If in the the RSL link budget. Antenna alignment should enable the RSL to be peaked to the level calculated is approximately 20 dB below the calculated level, then it is likely that the antennas are aligned on a sidelobe of the antenna's radiated signal. In this case, the antennas should be rotated in a wide arc until the main lobe is located.

Additional external lightning protection devices are recommended for the connections if the radio is installed in an area prone to lightning. Use only PolyPhaser or equivalent protectors that are rated for at least 2000MHz and pass DC current (non DC blocking type). The 1000BaseF connection to the Tsunami is at the data interface on the front of the shelf.

Prior to installing the system, it may be desirable to perform a back-to-back test of the Tsunami radio pair. Consult Section 4.9 for further details. Back-to-back testing is a simple way to verify that the Tsunami radios are fully operational before they are installed. Installation adds several variables (such as antenna alignment) which can lead to system turn-up delays. Also, during back-to-back testing, the DIP switch settings and some connections can be tested. This step can eliminate a majority of troubleshooting once the radios are installed. A cellular phone or two-way radio system (walkie talkie, CB, mobile radio) can be very useful during installation. These can be used for temporary near-end and far-end communications between the installation personnel at one site and installation personnel at the other site while installing the system. These can also be helpful for communication between a person at the top of a very tall tower and ground personnel. The Tsunami radio incorporates an internal Orderwire feature that provides end-to-end telephone style communications. However, the link must be partially operational to use this feature. In lieu of, or in addition to the use of cellular phones or two-way radio, this Orderwire feature can also be very useful for installation, but typically cannot be put into service until step 8 or 9 of this procedure is completed. See Section 3.14.1 for more details. 2. 3. 4. 5. 6. Perform a general alignment of the antennas on both ends of the path using binoculars, compass or other related tools. It is important to have the antennas aligned as accurately as possible before putting radio traffic over the link. This will help in getting the system running more rapidly. See Section 3.10 for more details. Connect the transmission line to the antenna, and feed it to the Tsunami radio location (see Section 3.9). Connect the opposite end of the transmission line to the N-type female connector located on the filter assembly which occupies the top half of the Tsunami rear panel. The connection must be terminated into an antenna or a load before DC power is applied to the radio. Verify that the same channel plan (e.g. A, B) as the near-end radio, and the opposite Tx and Rx frequencies (e.g. A1 and A2 make up a matched pair of radios). With the DC power source active, but not plugged into the Tsunami radio, using a voltmeter, confirm that the DC mating connector has the proper power connections in accordance with Section 3.7. Verify the polarity and the absolute voltage on all pins. Verify ground connection for power. Connect power to the Tsunami radio. Verify that the Front Panel ON LED indication is illuminated. This confirms that power has been properly applied. Ensure that the RF Antenna port connection is properly terminated before applying power to the Tsunami terminal, as in step 3. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-21 I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 When the Tsunami radio is initially powered-on, some alarm conditions may be present. This is normal and alarms can be ignored at this time. The Tsunami radio requires professional installation. With some Tsunami models, in certain countries, there may be Effective Isotropic Radiated Power (EIRP) limits which dictate the maximum output power that the Tsunami radio can transmit given the transmission line loss and the gain of the antenna. Consult with appropriate government agencies or Western Multiplex if there is any question regarding maximum output power allowed. Do not adjust output power above factory settings. 7. Connect a voltmeter to the ODUs test points (BNC connection). This voltage reading corresponds to the Received Signal Level (RSL) of the near-end radio. In other words, RSL is the amount of signal the near-end radio is receiving from the far-end radio. Since the antennas have not been finely aligned, it is not expected at this time that the RSL will read very high. However, at this point it can be verified that some communication is taking place between the two Tsunami terminals. Use the RSL voltage reading to align the antennas. Align one antenna at a time in accordance with Section 3.10. Complete alignment of both ends of the radio link before going further. The RSL voltage output on the radio's front panel will output a voltage over the usable range of the radio. Refer to Figure 3-8 in Section 3.8.2. RSL of both ends should be verified to be within approximately 2 dB of predicted value (see Section 3.3.3). There are several factors that can contribute to low RSL:

- Incorrect antenna alignment (aligned on a lobe and not on the main signal)

- Improper polarization alignment of antennas (horizontal vs. vertical)

- Transmission line problems (loose connections, bent or damaged cables, lossy adapters)

- Path obstructions (trees, buildings, hills, etc.)

- Path clearance (line-of-sight, earth curvature, Fresnel zone, diffraction and partial obstruction)

- Weather (inversion layers, ducting and multipath)

- Antenna feed (coaxial/connector) problem PAGE 3-22 SECTION 3: INSTALLATION & ADJUSTMENTS I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 The Tsunami radio requires professional installation. Dont forget that the transmitter output power adjustment on the Tsunami radio effects the RSL. Depending on EIRP limits (if any), path distance, and antenna gain, you may need to adjust the output transmit power to the proper level before putting the radios in service. If radio synchronization has been established, the radio link may be able to provide some limited communications over the link. It can be helpful to establish voice communications from one end of the radio link to the other using the Orderwire feature of the Tsunami radio. See Section 3.14.1 for details. If RSL is lower than anticipated, recheck the path clearance and transmission line as these are the typical causes of low RSL. Radio operations can be verified by connecting radios back-to-back with attenuators (40-60 dB), (see Section 4.9). If the problem remains, consult Section 4 of this manual for troubleshooting techniques which will help determine the source of the problem. 8. 9. Once radio performance is verified and acceptable, the Tsunami radios can now be put into service with the intended Gigabit Ethernet traffic. Connect to the LAN or computer using the SC (fiber) 1000BaseF connector. With Ethernet traffic applied in both directions, all front panel LEDs, except for POWER and the data TXD/RXD lights should be off. If any other LEDs are on, consult the trouble shooting sections of this manual. Now that the link is operational, other services can be connected including T1 (DSX-1), Orderwire, Diagnostics, Alarms and Aux Data (Service Channel). Consult Section 3.14 for details on these connections.

Telephone connection specifications:

(Ringing voltage is adequate for modern solid state ringers, NOT for the older mechanical type ringers) 1.0 B within 1.5% of nominal freq. 48 VDC, typical This Orderwire service does not affect the normal radio transmission of traffic. Refer to Section 2.3.5 for the telephone specifications. For simple near-end to far-end communications, follow the steps below:

1. 2. 4. Using a standard RJ-11 telephone cable, connect a standard electronic telephone (a touch tone phone, complete with dialer; a handset by itself will not work) to the Orderwire connector on the Tsunami front panel. This connector is wired identically to a standard two-wire telephone jack, see Figure 3-9 for details. With a telephone connected to each Tsunami terminal on opposite ends of the link, either telephone can be used to dial-up the far-end location. The far-end terminals internal ringer and the connected telephone will ring, and if answered, two-way full-duplex voice communication is established. If using the Orderwire or Network management functions, all Tsunami radios connected must have unique address settings

(telephone numbers). If the Tsunami radios are connected in a repeater configuration, Orderwire services can be established to all Tsunami terminals in the network by implementing a connection of their rear-

panel connectors between repeater terminals. At the repeater site, a cable can be connected to the two Tsunami terminals between their rear panel VF 9-pin connectors as shown in Figure 3-6. With this cable in place, the Orderwire function will operate at terminals at each end of the repeater and at the repeater site. This function can be continued through several repeater sites if desired. For hub connections of 3 or more Tsunami radios at the same site, an external 4-wire bridge is required to connect all radios to the orderwire. The orderwire system can be integrated with orderwire equipment supported by many other vendors.

Also can be used as an RS-232 port to download the latest revision radio operation software. The config port allows connection of RS-232 devices to receive status of the Tsunami radio and provide configuration. For RS-232 diagnostics connection (Section 4.11) to the Tsunami radio, connect the serial device

(modem, computer, terminal) to the male 9-pin subminiature connector in accordance with Figure 3-

These connections allows for standard DSX-1 connect of voice circuits without affecting the Ethernet traffic. A standard RJ-48c connector is provided for this connection. 3.11.6 CEPT-1 (E1) InterfaceConnection Not provided with this model at this time 3.11.7 NMS Interface Connection The NMS connection provides connection for the network management system. This allows an HTML interface to the Tsunami radio for purposes of monitoring, configuration and security settings. This connection is an RJ-45 style connection and complies to standard 100BaseT or F interface. Typically, the installer or manager will connect to the NMS with a stand-alone computer to initially configure the radio prior to installation. If IP addresses and security are set properly, the connection can also be used as an out-of-band connection for radio management. Alternatively, if the 100BaseT/F is connected to a network, or combined with the 100BaseT traffic on the link, via an external 10/100 switch, hub or router, full wireless NMS can be achieved for all radios in the network. The factory default IP address is set to 10.0.0.1. To reset the radio back to the factory default, Hold down the far-end test button while powering up the radio. Release the switch after 6 seconds. More details on the NMS connection can be found in Section 4 of this manual. In the future, this connection will also allow NMS via SNMP (Simple Network Management Protocol) in addition to the HTML interface that is presently supplied. Consult factory for details or assistance with NMS connections, if required. Ethernet Cable:Straight version to hub/switch, crossed version direct to PC.

Should a fault occur, it often may be resolved by operator adjustment. Should a fault occur that cannot be resolved by operator adjustment and has been confirmed by looping terminals together on the bench (See Section 4.7), then the equipment should be returned to the factory for repair. The Tsunami radio is a complex system not designed for user repair. Do not remove the cover or open any part of the Tsunami terminal. The complete Tsunami terminal should be sent back in its original packing material for factory repair. Please contact the factory in advance of returning the product. You will be assigned a Return Material Authorization (RMA) number that authorizes your return. Units sent to the factory without an RMA number may be delayed in the processing of the repair. Be sure to include the following information:

v RMA number v description of the problem v your name and telephone number v return shipping address v urgency of repair Please refer to the published Warranty policy for repair policy details. Tsunami radios should be packaged in their original packing boxes for shipment whenever possible Western Multiplex can provide an empty box shipment to facilitate proper packaging. Regardless, proper and adequate packaging must be used for shipments to protect the radio(s) from damage. Western Multiplex can not be held responsible for any repairs due to inadequately packed materials. Damage caused by improper packing will likely result in higher repair costs and delays (refer to the Warranty section at the beginning of this manual).

This LED indicates that the demodulator function is not synchronizing with the intended received signal. Possible Causes:

v Severe path fading due to atmospheric conditions, usually accompanied by low RSL voltage reading v Poor transmission line connections usually accompanied by low RSL voltage reading v Antenna problems, misalignment, or path clearance usually accompanied by low RSL voltage reading v Improper radio settings (e.g. frequency channel) v Received signal level (RSL) is too strong v Interference v Far-End radio transmitter circuitry is faulty v Near-End radio receiver circuitry is faulty v Link security ID not the same for each radio Recommended Actions:

Check the following at each end of the link:

v Verify that rear panel filters are opposite channel plans on each end (e.g. one is A1 and other is A2). v Verify that radio frequency settings match each installed filter (in NMS menus). v Verify that all connections between radios and antennas are secure and all devices between radios and antennas are rated for the radio frequency band (5.3/5.8 GHz). Measure RSL by placing a voltmeter across RSL and GND test points. Compare this voltage to the Factory Test Data Sheet and estimate the RSL in dBm. Compare this to the RSL that was expected using path calculations (see Section 3.3.3). Press and hold the DISPLAY FAR END button and measure the far-end RSL (while continuing to hold the button). Compare this RSL to the Factory Test Data Sheet for the far-end radio and estimate the RSL in dBm. Again, compare this RSL to the expected RSL from the link budget calculations. If RSL from both ends of the radio are approximately the same as each other, but lower than anticipated for this installation, then the likely cause of the BER alarm(s) is excessive losses between the radios. Excessive loss problems could include the transmission line at either end, all adapters, connectors, the antennas, the antenna alignment as well as the path itself (any obstructions or clearance problems). Antenna alignment, line-of-sight and path clearance should be verified; if this does not improve RSL, all devices between the radios and their antennas at both ends should be checked. Make sure all transmission line, connectors and any other devices are properly rated for operation at the radio's frequency (5.3/5.8 GHz). SECTION 4: TROUBLESHOOTING PAGE 4-5 I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 If only one end has low RSL, this could be caused by low transmit output power from the opposite end radio. Verify that the transmitter output power of the radio opposite to the low RSL receiver has been set in accordance to path calculations, or EIRP restrictions (where applicable). Power adjustment must be performed by professional installation personnel only. The PWR test point can be used and compared with the Factory Test Data Sheet, the front panel recessed potentiometer can be turned clockwise to increase power. If an RF power meter is available, this can be connected to the RF output of the radio for precision measurement. This test will also verify that the radio transmitter is working properly. If one terminal (or both) has high RSL, this could be caused by a very short path or interference. To verify the possible presence of interference, remove DC power to the radio which is opposite to the one that is reading high RSL. Once power is removed, measure RSL on the remaining radio. If RSL voltage is lower than that which is listed for "Threshold" in the Factory Test Data Sheet, then an interfering signal is present. If interference is suspected, the easiest potential remedy is to swap frequency channels on both sides of the link. See Section 4.2 for details. Swap terminals at both ends of the link so that they are the opposite from their original installation. After both ends are moved, reconnect the radios and determine if the BER alarm is still active. If the BER alarm is still active, other frequency channels can be installed, or other interference countermeasures can be tried, in accordance with Section 4.8. If all path related and data input problems have been pursued and the BER alarm is still active, the problem could be related to a radio failure. While radio failure is typically indicated by more severe alarm conditions, it is possible that one of the radios may be out of specification, and this could be the cause of the BER alarm. A back-to-back test will verify proper radio operation. See Section 4.9 for details. A threshold test on both radios along with a test to verify proper RF output power would be beneficial. Perform a back-to-back test before returning any radio terminal to the factory for repair. A back-to-back test verifies radio operation.

(See Section 4.7). If the radios successfully pass their back-to-back testing, the problem is likely with the path or the connections between the radio and the antenna or interference. Before reinstalling the radios, be sure to set the output power to the appropriate level for the installation.

The RADIO FAIL alarm indicates a known problem with the radio hardware. Possible Causes:

v Internal synthesizers are unlocked v Internal digital circuits have failed Recommended Actions:

1. Remove power from the unit. 2. Check to make sure power supply voltages are within specification. 3. Even if the voltages were within specification, reapply power to the unit. 4. If RADIO FAIL alarm clears, place the radio back into service. 5. If RADIO FAIL alarm does not clear, perform a back-to-back test to verify radio operation, as described in Section 4.7. 6. If RADIO FAIL alarm is still active in a back-to-back test, return the radio to the factory for repair (see Section 4.3).

This LED indicates that there is an alarm condition present on the far-end radio. When the DISPLAY FAR END button is pressed (and held), the status LEDs indicate the alarm conditions of the far-end radio. Possible Cause:

v One or more alarm condition(s) exist on the far-end radio Recommended Actions:

1. Press and hold the DISPLAY FAR END button and observe the LED status. 2. Follow instructions for troubleshooting the far-end radio in accordance to the appropriate LEDs which are in alarm, as described in Section 4.6.1.

This is usually known to the operator by either faulty data indications of downstream equipment or external bit error rate testing. It is possible that no alarms appear on the front panel during normal operations, but there are errors present in the data stream. Some errors will not result in no alarm (such as bipolar violations, slow "dribbling" errors, improperly terminated connections or incorrect settings), but will be exhibited on downstream data processing equipment or during a BER test. In other cases, there may be data errors due to atmospheric conditions (fading), interference or other reasons, but not at a high enough error level to be indicated with the BER alarm LED. In the case of these types of errors, the following information can be helpful to troubleshoot the radio link. Indications:

v During external BER test, test equipment indicates errors v Downstream equipment (mux, channel bank, CODEC, router, etc.) indicates errors Possible Causes:

v Path fading due to atmospheric conditions v Poor transmission line connections v Antenna problems, misalignment or path clearance v Received signal level (RSL) is too strong v Far-End radio transmitter circuitry is faulty v Near-End radio receiver circuitry is faulty v Interference Recommended Actions:

1. Verify 1000BaseF fiber connection and cable. 2. Follow the instructions described in Section 4.4.1 SECTION 4: TROUBLESHOOTING PAGE 4-9 I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 4.6 Back-to-Back Testing Back-to-back testing, as shown in Figure 4-1, is an ideal method of testing the Tsunami radios. This testing eliminates link problems caused by auxiliary equipment, installation, or the radio path and isolates potential radio hardware problems. Back-to-back testing must be performed with both radios at the same location. The following test equipment is required:

v DC power source capable of supplying approximately 250 Watts (total) to the radios. v Two coax couplings and 70dB loss attenuation per cable. v BER tester Back-to-back testing must be performed to verify a radio problem before returning any radio to the factory for repair. Use two coax cables and approximately 70dB attenuation per cable When the equipment is connected as shown in Figure 4-1, both Tsunami radios should have no alarm conditions. If these conditions have been met, then it is likely that the Tsunami radio is operating in accordance to specifications. If errors or alarms occur during this test, verify that all configuration settings are properly set. If alarms or errors are still present, the radio is likely to be faulty.

It can be performed from end-to-end or in link test mode (which tests both directions of the radio path). Figure 4-2 illustrates a typical test configuration (which may include the radios path instead of in-line attenuators). Figure 4-2 illustrates a typical test configuration for end-to-end testing. When performing testing, make sure of the following:

- Disconnect all 1000BaseF inputs and outputs to both radios.

- Verify all configuration settings. Link testing may be performed on the bench, with two terminals back to back, or over the radio path. Also, it may be performed from end-to-end (which requires two 1000BaseF test sets over a link, the far-end unit slaved to the near-end units clock) or in loopback mode) If link testing indicates an unacceptable level of errors, follow the instructions in Section 4.4.1. or perform a back-to-back test.

1) 2) 3) 4) SNMP Browser (IE, Netscape, etc.) graphical user interface Software upgrade procedure TelNet (via VT100 session using Windows Hyperlink) 4.8.1 SNMP Use your favorite SNMP access software such as HP OpenView. Please contact customer service/support to get a copy of the MIB file e-mailed to you or from our FTP site. 4.8.2 Browser GUI Use Internet Explorer or Netscape to access the radio by typing in its IP address. If you are setting up the radios for the first time, the default IP address is: 10.0.0.1 You will have to configure your computer to this domain first by setting its address to 10.0.0.5 and then changing the radios IP to one within the domain of your network. After changing one radios IP address (see Configuration tab) change the other radios IP address also, but not to the same address of the previous radio. Reconfigure the IP address of your computer to its original address and then restart the PC so it is now in the same domain as the radios. The browser interface shows a virtual front panel of the radio that is addressed. To view the front panel of the associated far-end radio, click on the window that is located on the virtual front panel

(see following illustrations). Illustrations on the next few pages of this manual provide details on all browser screens and operations. 4.8.3 In-band NMS Set-up Use a 4-port (or larger) 100/1000 switch (recommended as opposed to a hub that will also work) at each radio to operate the NMS in-band with the 100BaseT/F traffic. The NMS port can have a unique domain that is valid only with the PC that is being used for network management and system-wide operational status and will not interfere with 100BaseT/F traffic as the radio's MAC address plus its IP address are unique. Radios are set at the factory to IP addr: 10.0.0.1. Temporally set your PCs domain (write down its present IP address) to a suggested setting of PC=10.0.0.5-the PC will force a re-boot. Re-boot the PC computer attached to the first radio's 100BaseT NMS port and log-in to radio NMS w/favorite browser (IE or Netscape) after log-in (manager:manager). Change the IP address

(Configuration) to an unused one in your domain (if you want to also change the password at this time, do this first). Do the same with other radio (may have to reboot computer attached to this other 10.0.0.1 radio as the other's MAC address does not match the MAC/IP address the PC knows about). Set the IP address this radio to a different IP address in your normal operating domain. Set your PC back to its original domain (will force reboot again). This should allow for typical LAN operation. Type http://10.0.0.1/index.htm to gain initial access.

1) Connect the host PC tot the radio terminal through the NMS 10BaseT port. 2) Point the browser

(For factory default use 10.0.0.1 for the http: address) the radio's Web page "http//xxx.xxx.xxx.xxx/upload.htm". to 3) Login as "manager" for name and password on the GUI prompt. 4) Follow the instructions on the screen. a) Enter the file name you want to upload, e.g. (a:ts_nmu.udl software bianary image file), or select the browse button and point to the proper location. b) While the file name is displayed on the screen, select the install button. c) It will display a status child window indicating it is erasing and writing to the unused Bank.. (Note the Bank # for ref.) d) After it is complete, you will see this message "File upload finished and system will reboot! Restart browser to logon again"

e) Now, you can re-enter the upload GUI and insure the new uploaded Bank is valid and is the current Bank in use. Memory Banks:

The radio has two banks of flash memory available, Bank 0 and Bank 1, only one bank will be in use at a time. The radio will automatically utilize the new uploaded bank. In addition, through the procedure, you can also manually select Bank 0 or Bank 1 by selecting the (switch) button. Switching between Banks is quick and you will need to re-start the browser. Also, to determine if a flash memory Bank has any software, you can read the Bank status. E.g. Valid or invalid, invalid indicating that it is an empty memory Bank.

A: Ethernet is a type of network cabling and signaling specifications (OSI Model layers 1

[physical] and 2 [data link]) originally developed by Xerox in the late 1970. The IEEE's

(Institute of Electrical and Electronics Engineers) used Ethernet Version 2 as the basis for the 802.3 CSMA/CD network standard. Q: What is an 802.3 network?

A: That's IEEE-ish for Ethernet. Q: What is CSMA/CD?

A: CSMA/CD is the media access control mechanism used by Ethernet and 802.3 networks;

in other words, it determines how a packet of data is placed on the wire. CSMA/CD stands for "Carrier Sense Multiple Access, with Collision Detection". Before an Ethernet device puts a packet "on the wire", it listens to find if another device is already transmitting. Once the device finds the wire is clear, it starts sending the packet while also listening to hear if another device started sending at the same time (which is called a collision). Refer to the Q&A on collisions for more info about this phenomena. Q: What is an OSI Model?

A: The Open Systems Interconnect (OSI) reference model is the ISO (International Standards Organization) structure for the "ideal" network architecture. This Model outlines seven areas, or layers, for the network. These layers are (from highest to lowest):

LAYER 7) Applications: Where the user applications software lies. Such issues as file access and transfer (FTP), virtual terminal emulation, Internet connections (HTTP), inter-

process communication and the like are handled here. 6) Presentation: Differences in data representation are dealt with at this level. For example, UNIX-style line endings (CR only) might be converted to MS-DOS style

(CRLF), or EBCIDIC to ASCII character sets. 5) Session: Communications between applications across a net- work is controlled at the session layer. Testing for out-of-sequence packets and handling two-way communication are handled here. 4) Transport: Makes sure the lower three layers are doing their job correctly, and provides a transparent, logical data stream between the end user and the network service s/he is using. This is the lower layer that provides local user services. 3) Network: This layer makes certain that a packet sent from one device to another actually gets there in a reasonable period of time. Routing and flow control are performed here. This is the lowest layer of the OSI model that can remain ignorant of the physical network.

This layer is generally broken into two sub-layers: The LLC (Logical Link Control) on the upper half, which does the error checking, and the MAC (Medium Access Control) on the lower half, which deals with getting the data on and off the physical layer (wire, fiber and Tsunami Wireless Bridges). 1) Physical: The nuts and bolts layer. Here is where the cable, fiber, radio, connector and signaling specifications are defined. Q: What does an Ethernet packet look like?

A. See the information below, as described in the National Databook. The Ethernet packet preamble is normally generated by the chipset. Software is responsible for the destination address, source address, type, and data. The chips normally will append the frame check sequence.

| | Preamble

| 62 bits | A series of alternating 1's and 0's used by the

| | Ethernet receiver to acquire bit synchronization.

| | Start Of Frame Delimiter

| 2 bits | Two consecutive 1 bits used to acquire byte

| | alignment.

| | Destination Ethernet Address

| 6 bytes | Address of the intended receiver.

| | The broadcast address is all 1's.

| | Source Ethernet Address

| 6 bytes | The unique Ethernet address of the sending

| | station.

| | Length or Type field

| 2 bytes | For IEEE 802.3 this is the number of bytes of

| | data.

| 46 bytes | Data

| to | Short packets must be padded to 46 bytes.

| 1500 bytes |

| | Frame Check Sequence(CRC) -

| 4 bytes | The FCS is a 32 bit CRC calculated using

| | the AUTODIN II polynomial.

The shortest packet is: 6 + 6 + 2 + 46 = 60 bytes The longest packet is: 6 + 6 + 2 + 1500

= 1514 bytes Q: What is a MAC address?

A:

It is the unique hexadecimal (numbering base 16) serial number assigned to each Ethernet network device to identify it on the network.. With Ethernet devices (as with most SECTION 5: APPENDICES PAGE 5-3 I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 other network types), this address is permanently set at the time of manufacturer, though it can usually be changed through software (though this is generally a Very Bad Thing to do). Q: Why must the MAC address to be unique?

A: Each communicating end device (not bridges) has a unique MAC address, so that it will be able to exclusively grab packets off the network meant for it. If MAC addresses are not unique, there is no way to distinguish between two devices. Devices on the network watch network traffic and look for their own MAC address in each packet to determine whether they should decode it or not. Special circumstances exist for broadcasting to every device. Q: Is there a special numbering scheme for MAC addresses?

A: The MAC addresses are exactly 6 bytes in length, and are usually written in hexadecimal as 12:34:56:78:90:AB (the colons may be omitted, but generally make the address more readable). Each manufacturer of Ethernet devices applies for a certain range of MAC addresses they can use. The first three bytes of the address determine the manufacturer. RFC-1700 (available via FTP) lists some of the manufacturer-assigned MAC addresses. A more up-to-date listing of vendor MAC address assignments is available on ftp.lcs.mit.edu in pub/map/Ethernet-codes. Q: What does CRC mean?

A: Cyclical Redundancy Check - A method of detecting errors in a message by performing a mathematical calculation on the bits in the message and then sending the results of the calculation along with the message. The receiving work-station performs the same calculation on the message data as it receives it and then checks the results against those transmitted at the end of the message. If the results don't match, the receiving end asks the sending end to send again. Q: What do 10Base5, 10BaseT, 10Base2, etc mean?

A: These are the IEEE names for the different physical types of Ethernet. The "10" stands for maximum signaling speed: 10MHz. "Base" means Baseband. 10BaseT, where the T means twisted pair, and 10BaseF where the F means fiber (see the following Q&A for specifics). This actually comes from the IEEE committee number for that media. In actual practice:

10Base2 Is a maximum of 10MHz Ethernet running over thin, 50 Ohm baseband coaxial cable. 10Base2 is also commonly referred to as thin-Ethernet or Cheapernet. 10Base5 is 10MHz Ethernet running over standard (thick) 50 Ohm baseband coaxial cabling. 10BaseF is Ethernet running over fiber-optic cabling. 10BaseT is Ethernet running over unshielded, twisted-pair cabling. Q: What is UTP?

A: Twisted pair cables. UTP is for Unshielded, Twisted Pair, while STP is for Shielded, PAGE 5-4 SECTION 5: APPENDICES I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 Twisted Pair. UTP is what's typically installed by phone companies (though this is often not of high enough quality for high- speed network use) and is what 10BaseT Ethernet runs over. UTP is graded according to its data carrying ability (e.g., Level 3, Level 4, Level 5). 10BaseT Ethernet requires at least Level 3 cable. Many sites now install only Level-5 UTP (CATegory 5), even though level 4 is more than sufficient for 10BaseT, because of the greater likelihood that emerging high-speed standards will require cable with better bandwidth capabilities. Q: Are there any restrictions on how Ethernet is cabled?

A: Yes, there are many, and they vary according to the media used. First of all, there are distance limitations: 10BaseT generally accepted to have a maximum run of 100-150M, but is really based on signal loss in dB's (11.5db maximum loss source to destination). Then there are limitations on the number of repeaters and cable segments allowed between any two stations on the network. The rule is, any possible path between two network devices on an unbridged/unrouted network cannot pass through more than 4 repeaters or hubs, nor more than 3 populated cable segments. 10BaseT and 10BaseF are star-wired, so there is no minimum distance requirement between devices, since devices cannot be connected serially. You can install up to the Ethernet maximum of 1024 stations per network with both 10BaseT and 10BaseF. Q: When should I choose BaseT, BaseF (or others)?

A: The specific environment and application must be considered when selecting your media type. However, there are some general rules-of-thumb that you can consider:

Avoid using copper between buildings. The electrical disturbances caused by lightning, as well as naturally occurring differences in ground potential over distance, can very quickly and easily cause considerable damage to equipment and people. The use of fiber-optic cabling between buildings eliminates network cabling as a safety risk. There are also various wireless media available for inter-building links, such as laser, spread-spectrum RF and microwave. 10BaseT is the most flexible topology for LANs, and is generally the best choice for most network installations. 10/100/1000BaseT hubs, or multi-hub concentrators, are typically installed in a central location to the user community, and inexpensive UTP cabling is run to each network device (which may be 100m, or 330ft, from the hub). The signaling technology is very reliable, even in somewhat noisy environments, and 1 hubs will usually detect many network error conditions and automatically shut-down the offending port(s) without affecting the rest of the network (unless, of course, the offending port was your server, shared printer, or router to the rest of the world. 100/1000BaseF, and its predecessor, FOIRL, are the only recommended topologies for inter-building links. However, they need not be limited to this role. 100/1000BaseF can also be run to the desktop, though the cost is prohibitively high in all but the most specialized environments (generally, extremely noisy manufacturing facilities, or very security-conscious installations). More commonly, FOIRL (and now, 10BaseF) is used inside buildings and long distance wireless connections to form backbone networks. Q: Is there an official "standard" punch down scheme for 10BaseT?

SECTION 5: APPENDICES PAGE 5-5 I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 A: Get a copy of EIA/TIA-568, it covers all of that sort of stuff: horizontal, vertical, connectors, patch cords, cross-connects, etc. Q: Is it safe to run Unshield Twisted Pair next to power cable?

A: According to EIA/TIA-569, the standard wiring practices for running data cabling and companion to the above referenced EIA/TIA-568, you should not run data cable parallel to power cables. However, in reality, this should not be a problem with networks such as 10BaseT. 10BaseT uses differential signaling to pick the data signals off the wire. Since any interference from nearby power lines will usually affect all pairs equally, anything that is not canceled-out by the twists in the UTP should be ignored by the receiving network interface. Q: Can I connect the 10BaseT interface of two devices directly together, without using a hub?

A: Yes, but not more than 2 devices, and you also need a special jumper cable between the two 10BaseT ports:

RJ45 pin RJ45 pin

1 <--[TX+]--------[RX+]--> 3 2 <--[TX-]--------[RX-]--> 6 3 <--[RX+]--------[TX+]--> 1 6 <--[RX-]--------[TX-]--> 2 Q: What is a "segment"?

A: A piece of network wire bounded by bridges, routers, repeaters or terminators. Q: What is a "subnet"?

A: Another overloaded term. It can mean, depending on the usage, a segment, a set of machines grouped together by a specific protocol feature (note that these machines do not have to be on the same segment, but they could be) or a big nylon thing used to capture enemy subs. Q: What is a repeater?

A: A repeater acts on a purely electrical level to connect to segments. All it does is amplify and reshape (and, depending on the type, possibly retime) the analog waveform to extend network segment distances. It does not know anything about addresses or forwarding, thus it cannot be used to reduce traffic as a bridge can in the example above. Q: What is a "hub"?

A: A hub is a common wiring point for star-topology networks, and is a common synonym for concentrator (though the latter generally has additional features or capabilities). 10BaseT and 10BaseF Ethernet and many proprietary network topologies use hubs to connect multiple cable runs in a star-wired network topology into a single network. Hubs have PAGE 5-6 SECTION 5: APPENDICES I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 multiple ports to attach the different cable runs. Some hubs (such as 10BaseT) include electronics to regenerate and retime the signal between each hub port. Others (such as 10BaseF) simply act as signal splitters, similar to the multi-tap cable-TV splitters you might use on your home antenna coax (of course, 10BaseF uses mirrors to split the signals between cables). Q: What is a bridge?

A: A bridge will connect to distinct segments and transmit traffic between them. This allows you to extend the maximum size of the network while still not breaking the maximum wire length, attached device count, or number of repeaters for a network segment. Q: What does a "learning bridge"?

A: A learning bridge monitors MAC (OSI layer 2) addresses on both sides of its connection and attempts to learn which addresses are on which side. It can then decide when it receives a packet whether it should cross the bridge or stay local (some packets may not need to cross the bridge because the source and destination addresses are both on one side). If the bridge receives a packet that it doesn't know the addresses of, it will forward it by default. IEEEs standard for a learning bridge is 802.1D. Q: Is there a maximum number of bridges allowed on a network?

A: Per IEEE 802.1 (d), the maximum number of concatenated brides in a bridged LAN is 7. This number is rather arbitrary, however, and is based on simulations of application performance with expected bridge delays. In addition, the number assumes that all bridges are LOCAL (no remote WAN connections), and that the default Hold Time of 1 second is in place (this is the time after which a bridge will discard a frame it is holding). This prevents extra-late frame delivery. (i.e, a frame should never be delivered more than ~7 seconds after is it sent). The rule of thumb for wireless WAN bridged LANs is to limit the number of hops to 4. Q: What is a router?

A: Routers work much like bridges, but they pay attention to the upper network layer protocols (OSI layer 3) rather than data link layer (OSI layer 2) protocols. A router will decide whether to forward a packet by looking at the protocol level addresses (for instance, TCP/IP addresses) rather than the MAC address. Because routers work at layer 3 of the OSI stack, it is possible for them to transfer packets between different media types (i.e., leased lines, Ethernet, token ring, X.25, Frame Relay and FDDI). Many routers can also function as bridges. Q: So should I use a router or a bridge?

A: There is no absolute answer to this. Your network layout, type and amount of hosts and traffic, and other issues (both technical and non-technical) must be considered. Routing would always be preferable to bridging except that routers are slower and usually more expensive (due to the amount of processing required to look inside the physical packet SECTION 5: APPENDICES PAGE 5-7 I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 and determine which interface that packet needs to get sent out), and that many applications use non-routable protocols. Rules of thumb:

Bridges are usually good choices for small networks with few, if any, slow redundant links between destinations or for connecting distant LANs. Further, bridges may be your only choice for certain protocols, unless you have the means to encapsulate (tunnel) the un-

routable protocol inside a routable protocol. Routers are usually much better choices for larger networks, particularly where you want to have a relatively clean WAN backbone. Routers are better at protecting against protocol errors (such as broadcast storms) and bandwidth utilization. Since routers look deeper inside the data packet, they can also make forwarding decisions based on the upper-layer protocols. Occasionally, a combination of the two devices are the best way to go. Bridges can be used to segment small networks that are geographically close to each other, between each other and the router to the rest of the WAN. Q: Are there problems mixing Bridging & Routing?

A: Only if you plan on having bridged links in parallel with routed links. You need to be very careful about running bridges providing links in parallel to a router. Bridges may forward broadcast requests which will confuse the router there are lots of protocols you may not think of filtering (e.g. ARP, Apple ARP over 802.3 etc. etc.). Also, DECnet routers have the same MAC address on all ports. This will probably cause the bridge to think it is seeing an Ethernet loop. Q: Who makes the fastest/easiest/most advanced bridges or routers?

A: The IETF runs bench marks on a wide selection of wired/fiber bridges and routers. Network Computing runs bench marks for wireless routers (point-to-multipoint) and bridges (point-to-point). Q: What does "IPG" mean?

A: The InterPacket Gap (more properly referred to as the InterFrame Gap, or IFG) is an enforced quiet time of 9.6 us between transmitted Ethernet frames. Q: What means "promiscuous mode"?

A: Promiscuous mode is a condition where the network interface controller will pass all Ethernet frames, regardless of destination address, up to the higher level network layers. Normally the network controller will only pass up frames that have that device's destination address. However, when put in promiscuous mode, all frames are passed on up the network stack regardless of destination address. Promiscuous mode is usually used by network monitoring tools and transparent bridges. Q: What is a collision?

PAGE 5-8 SECTION 5: APPENDICES I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 A: A condition where two devices detect that the network is idle and end up trying to send packets at exactly the same time (within 1 round-trip delay). Since only one device can transmit at a time, both devices must back off and attempt to retransmit again. The retransmission algorithm requires each device to wait a random amount of time, so the two are very likely to retry at different times, and thus the second one will sense that the network is busy and wait until the packet is finished. If the two devices retry at the same time (or almost the same time) they will collide again, and the process repeats until either the packet finally makes it onto the network without collisions, or 16 consecutive collision occur and the packet is aborted. Q: What causes a collision?

A: See above. Ethernet is a CSMA/CD (Carrier Sense Multiple Access/ Collision Detect) system. It is possible to not sense carrier from a previous device and attempt to transmit anyway, or to have two devices attempt to transmit at the same time; in either case a collision results. Ethernet is particularly susceptible to performance loss from such problems when people ignore the "rules" for wiring Ethernet. Q: How many collisions are too many?

A: This depends on your application and protocol. In many cases, collision rates of 50% will not cause a large decrease in perceived throughput. If your network is slowing down and you notice the percentage of collisions is on the high side, you may want try segmenting your network with either a bridge or router to see if performance improves. Q: How do I reduce the number of collisions?

A: Disconnect devices from the network. Seriously, you need to cut- down on the number of devices on the network segment to affect the collision rate. This is usually accomplished by splitting the segment into two pieces and putting a bridge or router in between them. Q: What is a late collision?

A: A late collision occurs when two devices transmit at the same time, but due to cabling errors (most commonly, excessive network segment length or repeaters between devices) neither detects a collision. The reason this happens is because the time to propagate the signal from one end of the network to another is longer than the time to put the entire packet on the network, so the two devices that cause the late collision never see that the other's sending until after it puts the entire packet on the network. Late collisions are detected by the transmitter after the first "slot time" of 64 byte times. They are only detected during transmissions of packets longer than 64 bytes. It's detection is exactly the same as for a normal collision; it just happens "too late."

Typical causes of late collisions are segment cable lengths in excess of the maximum permitted for the cable type, faulty connectors or improper cabling, excessive numbers of repeaters between network devices, and defective Ethernet transceivers or controllers. Another negative concerning late collisions is that they occur for small packets also, but cannot be detected by the transmitter. A network suffering a measurable rate of late collisions (on large packets) is also suffering lost small packets. The higher protocols do not cope well with such losses. Well, they cope, but at much reduced speed. A 1% packet SECTION 5: APPENDICES PAGE 5-9 I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 loss is enough to reduce the speed of NFS by 90% with the default retransmission timers. That's a 10 times increase of the problem!

Finally, Ethernet controllers do not retransmit packets lost to late collisions. Q: What is a jam?

A: When a workstation receives a collision, and it is transmitting, it puts out a jam so all other stations will see the collision also. When a repeater detects a collision on one port, it puts out a jam on all other ports, causing a collision to occur on those lines that are transmitting, and causing any non-transmitting stations to wait to transmit. Q: What is a broadcast storm?

A: An overloaded term that describes an overloaded protocol. Basically it describes a condition where devices on the network are generating traffic that by its nature causes the generation of even more traffic. The inevitable result is a huge degradation of performance or complete loss of the network as the devices continue to generate more and more traffic. This can be related to the physical transmission or to very high level protocols. Q: How do I recognize a broadcast storm?

A: That depends on what level it is occurring. Basically you have to be aware of the potential for it beforehand and be looking for it, because in a true broadcast storm you will probably be unable to access the network. This can change dramatically for a higher level protocol. NFS contention can result in a dramatic DROP in Ethernet traffic, yet no one will have access to resources. Q: How can I prevent a broadcast storm?

A: Avoid protocols that are prone to it. Route (with routers) or Bridge (with wired/wireless bridges) when it is practical. Q: What is *high* traffic on an Ethernet? 5%? 20%? 90%?

A: High traffic is when things start slowing down to the point they are no longer acceptable. There is not set percentage point, in other words. Usually start paying attention when it gets over 40-50%. Q: Why do I see different throughput speeds?

A: Bridges (such as Tsunami) are ISO Layer 2 Data Link Layer (use MAC address for filtering) devices where they provide their full stated throughput. At level 2 (bridges) or 3

(routers) where hardware plays the major part, the most common tester is the SmartBits 200 product from NetCom Systems. At Application Layer 7, you will see less than 40%

throughput from the maximum capacity measured w/SmartBits due to the increased protocol/software overhead at that level. Layer 7 can be tested with software such as Ganymede's Chariot or Qcheck product. PAGE 5-10 SECTION 5: APPENDICES I N S T A L L A T I O N A N D M A I N T E N A N C E M A N U A L T s u n a m i F A M I L Y G I G A B I T E T H E R N E T W I R E L E S S B R I D G E S J A N U A R Y 2 0 0 1 As an example: testing copper CAT5 cable with SmartBits will test 100% throughput (let's say you can send/rcv a full 10Mbps). At Layer 7 you will be transferring data at the 10Mbps rate, but only 4Mbps of user data will transfer (Ethernet has a high overhead of bytes added to each data packet each time you go up a layer). The advantage is the more complex overhead makes the data virtually resilient to corruption and minor errors (i.e. collisions), its easy to reroute and can use inexpensive plug/play devices like hubs/switches instead of multiplexers as used in the telco industry (i.e. LYNX T1 radios) Western Multiplex tests at Layer 2 where bridges are defined. At layer 7 (Application Layer), you will see less than 40% or more depending on the other traffic that may be on the LAN as this layer is more dependent on the type of data being sent (it does not matter if it's wire, fiber or any Ethernet bridge -wired or wireless). Another way to look at it: the model 31145 12Mbps (10Mbps 10BaseT+T1/E1 wayside) bridge will test the same as a piece of CAT5 Ethernet cable. Q: How can I test an Ethernet?

A: This depends on what level you want to test. The most basic test (a.k.a., "the fire test") is to connect a pair of devices to the network and see if they can communicate with each other. If you want to test the electrical integrity of the wire (i.e., will it carry a signal properly), a TDR or cable scanner that incorporates TDR and other functions, would be the most comprehensive tool. If you need to test the performance or troubleshoot protocol transmission problems, you will need special and usually very expensive software, usually coupled with custom hardware, to capture, optionally filter, and analyze the network packets. Also, see the answer to the question above. Q: What is a "TDR"?

A: A Time-Domain Reflectometer is a tool used to detect cable faults. This device operates by sending a brief signal pulse down the cable and looking for its reflection to bounce back. By analyzing the reflected pulse, it is possible to make judgments about the quality of the cable segment. More advanced units can not only detect and identify the nature of the problem, but give a reasonably accurate indication of the problem's location (distance from the point of the test). There is also a device known as an OTDR, which is an Optical Time-Domain Reflectometer for fiber-optic cables. Q: What is a "BERT"?

A: Bit Error Rate Tester. This equipment is used to analyze the amount and types of errors that occur on a cable segment. Q: What (free) tools are there to monitor/decode/etc an Ethernet?

A: There are many built into most DOS ,Unix and other operating systems. For example, the ping command can be used to determine if a given host is alive, and will also tell you the round trip transmission time. The command ifconfig will tell you the status of the network interfaces. netstat will summarize statistics for network usage. DOS commands (through Windows DOS application) are:

Product Description 2.1. General Description The Tsunami license-free radios provide a new level of control and convenience in a digital communications network These Tsunami radios provide 100BaseT intelligent bridging between two locations without the delay and expense of installing cable or traditionai microwave. Because each owner controis the operation of the link, there is no reliance on any outside services. Tsunami radio operators are able to operate instant links whenever needed, and to be in control of their own network. The Tsunami offers two primary benefits:

CONVENIENCE Easy to install and operate with no user license requirements or frequency coordination in the USA.

(Other countries may require a user license and/or frequency coordination). CAPABILITY Full transparent Fast Ethernet connections with no throughput reduction over any line-of-sight distance (within legal limits of government regulation) cS Tsunami radios are |SO Layer 2 Data Link Layer (use MAC address for filtering) devices where they provide their full stated throughput. At level 2 (bridges) or 3/4 (routers) where hardware plays the major part, the most common tester is the SmartBits 200 product from NetCom Systems. At Application Layer 7, you will see less than 40% throughput from the maximum capacity measured with SmartBits due to the increased protocolfsottware overhead at that level. Layer 7 can be tested with software such as Ganymede's Chariot or Qcheck product (www.qcheck.net/index.himl. Use Qcheck (or equivalent), do NOT use PING for throughput testing (www.qcheck.netAwhyqcheck. html)!

As an example: testing copper CAT5 cable with SmartBits will test 100% throughput (let's say you can send/rcy a full JOOMbps}. At Layer 7 you will be transferring bits at the 100Mbps rate, but approximately only 45Mbps of user data will transfer (Ethernet has a high overhead of bytes added to each data packet frame each time you go up a layer). The advantage is the more complex overhead makes the data virtually resilient to corruption and minor errors (i.. collisions), it's easy to reroute and the network can use inexpensive plug/play devices like hubs/switches instead of multiplexers as used in the telco industry (Le. LYNX T1/E1/D$3 radios) Western Multiolex tests for stated throughput at Layer 2/3 where bridges are defined. At layer 7

{application layer), you may see less than 50% or more depending on the other traffic that may be on the LAN as this layer is more dependent on the type of data being sent {it does not matter if it's wire. fiber or any Ethernet bridge -wired or wireless). Another way to look at it: the model 31145 12Mbps

(10Mbps 10BaseT+T1/E1 wayside) bridge will test the same as a piece of CAT5 Ethernet cable. SECTION 2: PRODUCT DESCRIPTION PAGE 2-1 Tsunami FAMILY WESTERN FAST ETHERNET WIRELESS BRIDGES

Tsunami FAMILY . FAST ETHERNET WIRELESS BRIDGES We 5 TERN Multiplex JULY 2000 2.3.2 Test Points / Power Indicator ON This is an LED indication. When jit GREEN, Tsunami is powered. The Tsunami radio products do not have an on/off switch. GND This is a test point referenced to chassis ground. This is used in conjunction with the next two test points to measure voltages related to radio performance. RSL This is a test point that relates to the Received Signal Level (RSL). The voltage is measured with a voltmeter (using the GND test point for reference) which corresponds to the actual power level of the incoming received signal. While the DISPLAY FAA END button is pressed, this RSL voltage corresponds to the RSL of the far-end radio. These measurements are used during installation, maintenance and troubleshooting. Refer to Figure 3-6 in Section 3-20. LOCAL This is a test point which corresponds to the output transmit power of the radio. The TX PWR voitage is measured with a voltmeter (using the GND test point for reference) which corresponds to the actual power level of the outgoing signal. This measurement is used during instaliation, maintenance and troubleshooting ecm This voltage only applies to the near-end and does not allow measurement Ke of the far-end output transmit power, even when the DISPLAY FAR END button is pressed. There is a receptacte on the front panel to the right of the LOCAL TX PWR test point which is an installation adjustment allowing the output transmit power to be increased or decreased within the radio's specified limits. Using a small screwdriver, this adjustment is used to set the output power of the transmitter, in accordance to the path planning. The Tsunami system requires professional installation. Transmitted output

. Tsunami FAMILY WESTERN FAST ETHERNET WIRELESS BRIDGES Multiplex JULY 2000 2.3.5 Connections RF CONNECTION The RF port of the Tsunami radio is an N-type female connector that is an integral part of the filter assembly. The filter assembly occupies nearly the entire top half of the front panel. The N-Type connector is used to connect the antenna, typically using coaxial transmission line. In some cases, waveguide may be used as the primary transmission line, in which case a waveguide-to-N adapter is required. For the Tsunami, 1/2" or 5/8 coaxial cable {LDF4-50 or LDF4,5-50) is recommended. Coaxial cable that is 7/8 or larger can exhibit moding at 5.8 GHz and is not recommended for 5.8 GHz radios. For waveguide transmission line at 5.8 GHz, EW-52 waveguide is recommended. EW-63 will also work, but may exhibit more loss. DATA CONNECTION The connection for the Fast Ethernet interface that carries the signals in and out of the radio is an RJ45 100BaseT wire connection or ST 100BaseT fiber connection. DC POWER CONNECTION The input accepts positive or negative DC power al any voltage between 20 and 63 Volts. Optionally, an AC power adapter can be used. OPTIONAL CONNECTIONS There are several connections that are not required tor operation, but provide additional facilities to the user. EOW This connection is used to access the electronic orderwire function. This is a facility for "telephone" style service from one radio to another. A standard electronic telephone [one with a handset and DTMF (push-button tone) dialing] plugs into this connector. The user can dial the orderwire address of the far-end radio (or any radio in the Tsunami network) to establish telephone communication between sites. This communication does not interrupt or interiere with the other radio communications. The radio link must be operational to use this facility. The orderwire feature can be very useful for installation, maintenance and troubleshooting. This connector is used to link two Tsunami radios at a repeater site for Orderwire operation. This would allow orderwire "telephone" calls to and from any point in the Tsunami network. VF nee The Tsunami orderwire circuit can also be connected to other existing ip: orderwire networks. See Section 3.14.1 for details. ALARM This connecter is used tor monitoring alarms electrically. The Form C relays can be connected to other transmission equipment for monitoring alarm status locally or remotely.

Multiplex 3.3 Before Installation Task List There are several tasks that should be accomplished prior to installing the Tsunami radio system. This section briefly describes the following:

- Site selection

- Line-of-Sight and Path Clearance determination

- Anticipated RSL calculation

- Fade margin caiculation

- Availability catculation

- Frequency plan determination

- Power supply planning

- Antenna (and accessories) purchase Only directional antennas should be used with Tsunami radios. These are typically flat panel or solid parabolic antennas.

@ Western Muitiplex recommends a maximum beamwidth of 10 degrees for directional systems. 3.3.1 Site Selection Requirements The radio site must have:

- access te the appropriate power

- close proximity to the telephone or computer system you wish to interconnect

- line-of-sight to the other radio location with adequate clearance

- location for mounting the antenna i SECTION 3: INSTALLATION & ADJUSTMENTS + PAGE 3-3 Tsunami FAMILY WESTERN FAST ETHERNET WIRELESS BRIDGES

( INSTALLATION AND MAINTENANCE MANUAL Multiplex JULY 2000 3.3.2 Line-of-Sight and Path Clearance Guidelines The Tsunami radios will not operate properly unless they have line-of-sight between their corresponding antennas. The Tsunami radio transmission will not pass through trees or other obstacles. Factors to consider include:

- Earth curvature

- Future growth of trees

- Height of buildings in addition to the line-of-sight requirement, a weil-engineered path will also have additional path clearance to allow for signal loss due to partial obstructions, atmospheric ducting and ground reflections. Te maximize radio reception, 0.6 times the first Fresnel zone should be calculated and this distance added to the path clearance (in addition to trees or buildings). a PAGE 3-4 SECTION 3: INSTALLATION & ADJUSTMENTS Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES JULY 2000 WESTERN INSTALLATION AND MAINTENANCE MANUAL (

Multiplex 3.3.3. RSL Calculation and Link Budget The received signal level (RSL) can be estimated using the following formula:

RSL (dBm) = P,,- FL,+ G, +G,- FL, -L, where: P.,, is the transmitter output power (in dBm) FL, is the feeder loss of the transmit side (in dB) G, is the gain of the transmit antenna (in dB) G, is the gain of the receive antenna {in dB) FL, is the feeder loss of the receive side (in dB) L is the Path loss, defined by:

L, (dB) = 96.6 + 20 log,,F + 20 log, .D where: F = Frequency in GHz (2.4 or 5.8) D = Distance of path in miles This link budget is very important for determining any potential problems during installation. If you have calculated the expected RSL, you can see if it has been achieved during installation, and troubleshoot if necessary. In the USA and Canada, Tsunami radios may be installed with any gain directional antennas but with a total system limit of +30 dbm EIRP for the 5.3 GHz transmitter

@ channel frequencies. 5.8 GHz transmitters have an EIRP limit of +53 dBm. For the equation above, replace the P,, - FL,+ G, by the EIRP limit. rr re SECTION & INSTALLATION & ADUUSTMENTS: PAGE 3-5 Tsunami FAMILY WESTERN FAST ETHERNET WIRELESS BRIDGES

( INSTALLATION AND MAINTENANCE MANUAL Multiplex JULY 2000 3.3.4 Fade Margin Calculation The fade margin is the difference between the actual received signal and the radios threshold. Using the formula provided in Section 3.3.3, the anticipated RSL can be calculated. Compare this RSL to the specified threshold of the Tsunami radio (shown in Section 2.2) and calculate the fade margin as the difference between the two signal levels. 3.3.5 Availability Calculation Availability of the microwave path is a measure of the percent of the time that the link will operate without producing an excessive BER due to multipath facing. In the absence of direct interference, avaitability is affected by the following: ,

~ Path length

- Fade margin

- Frequency (5.3 or 5.8 GHz in the case of these Tsunami radios)

- Terrain (smooth, average, mountainous)

- Climate (dry, temperate, hot/humid) Depending on the type of traffic carried over the link, the system designer may wish to design for

@ specific availability. For example, if the data or voice traffic that is carried by the radio is critical then it may be designed for a very high availability (e.g. 99.999% or 5.3 minutes of outage per year). To improve availability, for example, the fade margin can be increased by making the path shorter, or by using higher gain antennas in conjunction with lower loss feeders (by using high quality ttansmission fine or shortening feed length). Oa See PAGE 3-6 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY . FAST ETHERNET WIRELESS 8RIDGES We s TERN JULY 2000 Multiplex 3.3.6 Frequency Plan Determination When configuring radios in a hub or repeater configuration, careful engineering of the Tsunami radio frequency plans and antenna locations shouid be performed in order to minimize potential interference between the nearby radios. As a rule of thumb, do not place identical frequency plan radios (e.g. two A channel radios) at the same site. In most cases, it is desirable to use a different frequency pian (e.g. A versus 8). However, with careful engineering, placing more than one radio of the same frequency channel! pian at the same site is easily accomplished. In fact, the Tsunami frequency pian is designed to allow complex hub configurations that may require re-

using the same frequency plan. When designing these types of configurations, antenna size and antenna location are critical. If identical channel plans must be used at the same site, the same radio channel (e.g. A1 and At) should be used at a site to minimize interference. Using alternate channels (e.g. Al and A2) is less likely to be successful (and therefore not recommended) due to the high level of transmitter to receiver isolation required from the antenna system. Sometimes it is required to locate the Tsunami radio nearby a transmitter that is the same as, or close to the Tsunami receive or transmit frequencies. In this case, the Tsunami terminal that should be placed closest to this interfering transmitter should be the specific terminal with the receive frequency which is furthest from this unwanted transmitted frequency. This approach minimizes the potential of interference. While interference conditions are rare when using the Tsunami radios, cases of interference may be overcome by exchanging the radios from end to end or simply reinstalling a different filter unit (if applicable), as described in Section 4.2. In some cases, changing frequency plans (e.g. from A to B) can also help mitigate any interference. SSS Section 4.8 of this manual describes interference Ie countermeasures in further detail. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-7 Tsunami FAMILY WESTERN FAST ETHERNET WIRELESS BRIDGES G INSTALLATION AND MAINTENANCE MANUAL Multiplex JULY 2000 3.3.7. Power Supply Planning The Tsunami tadio must have access to a supply of appropriate power, either DC or AC (if the AC adapter option has been ordered). The Tsunami can be powered from a DC battery system, or from a solar or generator power plant, usually with battery reserves. Typically either a positive or negative ground 24 or 48 volt supply is used. For DC, be sure the cable is of sufficient gauge to carry the necessary current and it is less than three (3) meters (9.75 feet) in length. Before installing the radio, plan for the continuous power consumption needs in accordance with the specifications given in Section 2.2 of this manual. It is also wise to plan for backup power for critical communication circuits (including the Tsunami radio). Backup power allows the radios and associated equipment to continue operation when primary power is interrupted. 3.3.8 Anienna Planning Using path planning mathematics, proper antenna size can be determined which will yield the desired path performance. In general, the larger the antenna that is used with the Tsunamf radio, the better the link will perform. Larger antennas have narrower beamwidth and higher gain, which will yieid better link performance (higher fade margin, betier availability) and improve immunity to interference (due to the smatler beamwidths), However, larger antennas are more costly to purchase and install than smalier antennas, in some cases requiring special equipment for installation. All of these factors should be taken into consideration when selecting antennas. use of larger antennas will maintain the benefit of narrow beamwiaths and receive gain. However, oujput power may need io be reduced to meet regulations. (See Section 3.13.1)

@ in areas where transmitted output power restrictions apply, the Prior to installation, the specific antenna location and mounting should be determined. This advanced planning also yields the transmission line requirements. Only directional antennas should be used with Tsunami radios. These can be flat panei or solid parabolic antennas. ee PAGE 3-8 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY .

Blank rack-mounting spaces above and below the Tsunami are recommended, especially if the surrounding equipment dissipates a considerable amount of heat (over 40W). The Tsunami radio may be set up for mounting with the front edge projecting from the tront face of a standard 19-inch rack using the rack mounting brackets enclosed with the screws in the Accessory Kit (4 per bracket). The rack mounting brackets may be reversed, in order to install for flush or cabinet mounting if preferred. Depending on rack configuration, it may be necessary to remove the four adhesive backed rubber feet on the bottom of the unit. The Tsunami radio has internal fans which intake and

@ exhaust on the left and right sides of the chassis. When rack mounting, it is important to leave a smail gap between the outer edges of the radio and the inside edge of the rack. The Tsunami radio may alternatively be placed on a table or shelf attached to a wall.

. Tsunami FAMILY WESTERN FAST ETHERNET WIRELESS BRIDGES Multiplex JULY 2000 3.8 Antenna Connection The Tsunami radio is equipped with an N-type female connector at the antenna port located on the rear panel. A short length (~6 feet) jumper cable such as RG-214 coax {or pigtail) fitted with two N-type mate connectors can be used to connect the antenna Port to the antenna transmission line (see Section 3.9), The recommended cabie type for a jumper is RG-214. A low loss 50-ohm cable (for example LDF4-50 1/2 inch coax) or EW-52 waveguide is recommended for the antenna transmission line between the top of the rack and the antenna. The return loss presented by the transmission line at the top of the rack should be as high as possible

(20 dB, minimum recommended). The length of the antenna transmission line should be kept as short as possible (to minimize losses). To minimize feeder losses, the use of elliptical waveguide is recommended (typical loss is 1.25 dB/100 ft) for feeder lengths in excess of 200 feet. Depending on path length and feeder length, 1/2 inch or 5/8 inch coax cable can be used. For the Tsunami radio, 1/2 or 5/8 coaxial cable (LDF4-50 or Coe LDF4.5-50) is recommended. Coaxial cable 7/8" or farger can Se exhibit moding at 5.8 GHz and is not recommended for 5.8 GHz radios. For waveguide transmission line at 5.8 GHz, EW-52 waveguide is recommended. EW-63 will also work, but may exhibit more Joss. Do not use right angle N-type connectors with the 5.8 GHz wy Tsunami radios: they may present high toss at 5.8 GHz.

FAST ETHERNET WIRELESS BRIDGES WESTERN JULY 2000 Multiplex 3.9 Transmission Line Connection The transmission line feeder (such as LDF4-50 1/2 inch coax cable or EW-52 elliptical waveguide} should be prepared first by cutting to the approximate tength (allowing some excess) and installing the appropriate connector on the antenna end. The prepared transmission line is then pulled through the cable ducts, trays or conduit (as required) to the antenna, while being careful not to kink or damage the transmission line in any way. The transmission line should be supported in a tray on horizontal runs and by hangers on vertical runs. Hangers should be spaced according to the manufacturer's instructions (typically every 5 feet under conditions of no ice and not greater than 85 mph winds}. The transmission line should be grounded using the manufactures recommended grounding kit. Grounding kits attach to the outer copper conductor. Grounds must be installed at the antenna, at the bottom of the tower (if applicable} and where the transmission line enters the building. Long transmission line runs should be grounded every 100 feet. in areas of high incidence of lightning, dissipaters should be attached to antennas. In addition, coaxial, in-line, spark-gap type, lightning Suppressors should be added at the bottom of the coax cable before entering the building/enclosure. Any in-line lightning protection device must be rated for the

@ operating frequency of the Tsunami (5.3/5.8 GHz}. After installation, the transmission line is terminated with an N-type male connector/adapter attached at the equipment end. For waveguide, this typically requires a CPR-to-N adapter. Prior to operation, the electrical integrity of the transmission line, including all connectors, can be checked with a simple DC check between the center conductor and outer conductor. (This is neither possible, nor required for waveguide). The transmission line shouid ideally be connected directly to the antenna at one end and to the Tsunami antenna port at the other end. However, short RG-214 type pigtail jumper cables may be required to avoid sharp bends in the transmission line to limit steess on either connection. 7/8 inch coax cable or larger is not recommended for use at 5.3 GHiz and higher frequencies. wy Do not use right angle N-type connectors with the 5.3 or 5.8

Tsunami FAMILY We 5 TERN FAST ETHERNET WIRELESS BRIDGES Multiplex JULY 2000 3.10 Antenna Installation & Alignment INSTALLER CAUTION: Antennas used for this device must be fix-mounted on permanent outdoor structures to provide 5 meter or more separation from all persons during device operation to comply with FCC and other regulatory RF Exposure requirements. installers should contact the manufacturer for applicable antenna gain and type restrictions to ensure compliance. The antenna installation consists of permanently mounting the antenna outdoors on a tower, building roof, or other location that provides line-of-sight path clearance to the far-end location. In general, antennas smalier than 2 feet diameter are not recommended for urban areas due to their wider beamwidths, which results in higher interference susceptibility. Antennas should be ordered with a suitable mounting kit specific to the site requirements. For exampie, specifying round or angle tower leg adapters, or a roof tripod as necessary. The antenna must be very rigidly mounted, with adequate room for azimuth and elevation adjustment from the rear. The antenna polarization must be the same at both ends of the link, either vertical or horizontal. in general, antenna mountings require a support pipe to which upper and lower support brackets are attached with U bolts. The antenna and optional elevation and azimuth adjustment rods are then mounted onto the support brackets. The whole structure must be adequately grounded for lightning protection. The antenna system must always be installed according to the manufacturer's instructions, Unless special test equipment is available, two operating Tsunami terminals are required to align the antennas. Altematively, a CW generator may be used to transmit a signal toward the end under alignment. The antenna is coarse aligned using visual sighting and then fine aligned using the receive signal level (RSL) voltage of the Tsunami. The RSL voltage reading can still be used to peak antennas even if the radios have not synchronized, however far-end RSL cannot be measured from the near-end terminal until radios are synchronized. To coarse align the antenna, first set it for flat elevation (no up or down tilt) using a spirit level. Then point it at a heading marker obtained using a compass back-bearing fron an adjacent location, (ideally, 100 feet or more away from the antenna). lf a heading marker cannot be set sufficiently far away (for example when ona city building roof or looking through a window) then a rough azimuth setting can be obtained by sighting along the antenna feed. rr PAGE 3-18 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL ~

. If should be verified that both antennas are on the same Ap: polarization by using the manufacturer's instructions. Otherwise 2s fhe RSL will be approximately 25 to 30 dB below the calculated level. Most antennas will also need fine alignment obtained using an operating link because it is very important to maximize the receive RF signal levei at each end of the radio link.

@ Read Section 3.7 before applying DC power to the Tsunami radio. Once the coarse alignment has been set-up at both ends, then the link can be powered and some ievel of reliable communication established. The voltage at the Tsunami front panel RSL test point should be measured with a DVM to determine the relative receive RAF signal level. For the fine alignment, adjusting first the azimuth and then the elevation of the loca! antenna will maximize the RSL voltage. Then, the far antenna is aligned in the same way, using the RSL voltage of its local Tsunami radio. When aligning antennas it may be convenient to run two wires from the ASL and ground test points to the antenna so that the voltmeter reading is directly visible to the technicians aligning the antenna. Also, a cellular telephone or two-way radio may be useful for coordinating alignment activities between both ends of the link. Once the radios are coarse aligned and synchronized, the built-in orderwire phone service can also be used to coordinate alignment between both ends of the link. An orderwire telephone will provide end-to-end voice whe communications once radios are synchronized. Synchronization Y usually can be accomplished by coarse alignment only. After

: synchronization, the orderwire phones can be used to communicate between radio sites for antenna fine alignment. The phone interconnect cable can be extended to the antenna when desired. The larger the antenna size, the more critical alignment becomes: for example, with a 2 foot dish, the antenna can be moved #3 degrees off the correct heading before the receive signal level drops by 3 dB. This compares with a 6-foot dish which may only be moved +1 degree for the same degradation. The graph shown in Figure 3-6 shows the typical variation of RSL voltage as the receive signal level is increased from threshold to a higher level. There is some variation between Tsunami receivers, but an approximate estimate of the potential RSL value may be made using this figure. cS Use the Factory Test Daia Sheet shipped with your Tsunami terminal to

=< obtain fhe best estimaie of your RSL. Above 0 dBm RSL, the receiver may produce errors: however this level is rarely likely to be exceeded. A link budget calculation should be made to calculate the anticipated RSL as described in Section 3.3.3. During anomalous propagation conditions, the RSL may fade but will net increase up more than 10 dB (except in unusual very long paths which may fade up by 15 dB). SECTION 3: INSTALLATION & ADJUSTMENTS, PAGE 3-19 G WESTERN Multiplex q Antenna alignment should enable the RSL to be peaked to the level calculated in the link budget. if the RSL is peaked but is approximately 20 dB below the calculated level, then it is likely that the antennas are aligned on a sidelobe of-the aniennas radiated signal. In this case, the antennas should be rotated ina wide arc until the main lobe is iocated. {Other possible causes of tow RSL are path obstructions, joss in connectors, adapters and pigtail jumper cables or different antenna polarization at each end of the link.)

( INSTALLATION AND MAINTENANCE MANUAL Multiplex JULY 2000 3.12 System Turn-up to Service 1. Prior to installing the system, it may be desirable to perform a back-to-back test of the Tsunami radio pair. Consult Section 4.9 for further details. Back-to-back testing is a simple way to verify that the Tsunami radios are fully operational before they are installed. installation adds several variables (such as antenna alignment) which can lead to system turn-up delays. Also, during back-to-back testing, the DIP switch settings and some connections can be iested. This step can eliminate a majority of troubleshooting once the radios are instaled. A cellular phone or two-way radio system (watkie talkie, CB, mobile radio) can be very usetul during installation. These ae can be used for temporary near-end and far-end Ay communications between ithe installation personne! at one Site and installation personne! at the other site while installing the system. These can also be helpful for communication between a person at the top of a very tail tower and ground personnel. The Tsunami radio incorporates an internal Orderwire feature that provides end-to-end telephone style communications. However, the link must be partially operational to use this feature. In lieu of, or in addition to the use of cellular phones or two-way radio, this Orderwire feature can also be very useful for installation, but typically cannot be put into service until step 8 or 9 of this procedure is completed. See Section 3.14.1 for more details, 2. Perform a general alignment of the antennas on both ends of the path using binoculars, compass or other related tools. It is important to have the antennas aligned as accurately as possible before putting radio traffic over the link. This will heip in getting the systern running more rapidly. See Section 3.10 for more details. 3. Connect the transmission line to the antenna, and feed it to the Tsunami radio location

(see Section 3.9). Connect the opposite end of the transmission line to the N-type female connectar located on the filter assembly which occupies the top half of the Tsunami rear panel. The connection must be terminated into an antenna or a load before DC power is applied to the radio. 4, Verify that the same channel plan (e.g. A, B) as the near-end radio, and the opposite Tx and Rx frequencies (e.g. A1 and A2 make up a matched pair of radios). 5. With the DC power source active, but not plugged into the Tsunami tadio, using a voltmeter, confirm that the DC mating connector has the proper power connections in accordance with Section 3.7. Verify the polarity and the absolute voltage on all pins. Verify ground connection for power. 6. Connect power to the Tsunami radio. Verify that the Front Panel ON LED indication is illuminated. This confirms that power has been properly applied. __ OOOO PAGE 3-22 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY .

When the Tsunami radio is initially powered-on, sore alarm vf conditions may be present. This is normal and alarms can be ignored at this time. 7. Place a voltmeter across the GND and PWR front panel test points. See Figure 3-7 for voitage setting information and Table 3-C for typical output power levels for given cable lengths where EIRP limits apply.

: For precision measurement of transmit output power, it is best oe to connect an RF power meter to the antenna port. The PWR

# port voliage may not provide enough precision. This is especially important where EIRP limits apply to the installation. sping! in eases of no EIRP limits, the radio transmitter ouiput power oy: should be left at the factory setting, except for very short paths using very high gain antennas, where excessive power may not be advised. Don forget that fhe RF output port should be terminated at ail times when power is applied to the Tsunami radio. Therefore, disconnect power to the radio before connecting a power meter and reapply power once connected. Often, an AF power meter may have a limit to the input power that it can measure without damage. It is advised to place a calibrated fixed value RF attenuator (typicaily 20 dB or more) between the Tsunami radio and ihe power meter to assure proper operation and safety for the RFE power meter. The vaiue of this fixed attenuation can then be added fo the vaiue of the RF power meter reading fo obtain the actual Tsunami radio transmitter cutpul power. 8, Connect a voltmeter across the GND and RSL front panel test points. This voltage reading corresponds to the Received Signal Level (RSL) of the near-end radio. In other words, RSL is the amount of signa! the near-end radio is receiving from the far-

end radie. Since the antennas have not been finely aligned, it is not expected at this time that the RSL will read very high. However, at this point it can be verified that some communication is taking place between the two Tsunami terminais. Use the RSL voltage reading to align the antennas. Align one antenna at a time in accordance with Section 3.10. Complete alignment of both ends of the radio link before going further. The RSL voliage output on the radio's front panel will output a i voltage over the usable range of the radio. Refer to Figure 3-6 in Section 3-20. The Tsunami radio has a unique feature of allowing measurement of the far-end ASL from the near-end radio. This is only possible if the Tsunami radias are communicating

(the RSL is above threshold). The far-end RSL can be used to verify that adjustments to local antenna alignment are corresponding to the far-end radio reception. Far-end RSL is measured by pressing and holding the DISPLAY FAR END front panel button. While this button is held, the RSL voltage indicates the RSL of the far-end radio. RSL of both ends should be verified to be within approximately 2 dB of predicted value (see Section 3.3.3). There are several factors that can contribute to low RSL:

- Incorrect antenna alignment (aligned on a tobe and not on the main signal)

- Improper polarization alignment of antennas (horizontal vs. vertical)

- Transmission fine problems (loose connections, bent or damaged cables, lossy adapters)

- Path obstructions (trees, buildings, hills, etc.)

- Path clearance (line-of-sight, earth curvature, Fresnel zone, diffraction and partial obstruction}

* one end of the radio link to the other using the Orderwire feature of the Tsunami radio. See Section 3.14.1 for details. lf RSL is lower than anticipated, recheck the path clearance and transmission line as these are the typical causes of low ASL. Radio operations can be verified by connecting radios back-to-back with attenuators (40-60 dB), (see Section 4.9). If the problem remains, consult Section 4 of this manual for troubleshooting techniques which will help determine the source of the problem. 9. Once radio performance is verified and acceptable, the Tsunami radios can now be put into service with the intended Fast Ethernet traffic. Connect to the LAN or computer using the RJ45 (wire) or ST (fiber) 100BaseT connector. With Fast Ethernet traffic applied in both directions, all front pane! LEDs, except for POWER and the data TXD/RXD fights should be off. If any other LEDs are on, consult the trouble shooting sections of this manual. 10. Now that the link is operational, other services can be connected including T1 (DSX-1), Orderwire, Diagnostics, Alarms and Aux Data (Service Channel).

to meet EIRP (effective isotropic radiated power) Itmits.

* to avoid exceeding the maximum far-end RSL of -30 dBm.

+ to coordinate a hub or repeater location. To ensure maximum protection of the radio circuits, always

@ ensure the antenna connector is terminated when power is applied. Never adjust output power above factory settings. For precise measurement of transmitter power, a calibrated RF power meter (such as the HP 435B with Power Sensor HP8481) is recommended. This power sensor can be connected cirectly to the output of the radio without exceeding the power rating. With some power meters, it may be necessary to place a calibrated in-line fixed attenuator between the radio antenna port and the power meter so as to not exceed the power meter's maximum input level. Thruline power meters do not operate at Tsunam/ RF frequencies. ff adjusting the output power to meet an EIRP limit, it will be first necessary to calculate the overall system gains and iosses, including feeder losses for the type of transmission line installed and the antenna gain. Also refer to Table 3-C for transmitter output power settings where installed with various transmission line lengths and antenna sizes. You may determine the radio transmit power for EIRP limited installations by the following equation:

Tx Power (dBm) = EIRP Limit(dBm) + Feeder Loss(dB) - Antenna Gain(dB) Tes For the US and Canada, a +30 dBm EIRP limit applies for the dual band (5.3/5.8 GHz) Tsunami radios and a +53 dBm EIRP limit applies for the single band (5.8 GHz) Tsunami radios. Output power may be adjusted using a small screwdriver and rotating the potentiometer which is recessed behind the front panel. Ciockwise rotation increases output power while counter-

clockwise rotation decreases output power. In figu of a caliorated RF power meter, the PWR test port voltage can be used to estimate the output power. Figure 3-7 illustrates the voltage reading for various output power levels. The factory test data sheet should be used to establish a more precise setting of this adjustment. After setting the correct output power, place the cover cap found in ihe installation accessory kit over the front panel receptacie.

Tsunami FAMILY WESTERN FAST ETHERNET WIRELESS BRIDGES INSTALLATION AND MAINTENANCE MANUAL Multiplex JULY 2000 4.2 Changing Frequency Plans The Tsunami RF frequency selections are listed in Section 3.5. The near-end radio and the far-

end radio must be corresponding (e.g. A1 / A2). The frequency of a given Tsunami terminal is set by the specific filter, the physical orientation of this assembly, and a setting within the CONFIG port (or NMS configuration instructions, Section 4.11). With respect to a given filter, the frequencies are fixed, because tuned RF filters are required for normal operation. Changing of the

(pre-tuned) radio frequencies may be required when installing spares or for special situations, such as interference mitigation. This is accomplished by installing an alternate filter. Itis not necessary to remove the cover assembly of the Tsunami 1. Remove any cabies connected to the antenna connector on the dipiexer (filter) and then temove the two screws that mount the filter to the Tsunarni chassis. 2. Slowly remove the filter from the chassis being careful to not endanger the cables that are connected to the rear side of the filter. 3. Disconnect the two SMA connectors that are attached to the rear of the filter with a 5/16 open end wrench. 4. Select the new filter such that the frequency channel label on the filter corresponds to the desired frequency channel (or rotate filter if applicable see note below). 5. Connect the two SMA connectors to the new or reoriented filter with the 5/16 open end wrench. 6. Slowly place the wired filter assembly so that it is flush with the rear panel. 7. Install the two screws that mount the filter to the rear panel. 8. Modify the operating frequency as described in the CONFIG menus {Section 4.11) Single-band versions of this radio can be interchanged irom Al to A2 by changing (bul not rotating) the installed filter. After filier is changed the frequency settings within the configuration menu (NMS) must be changed to match the installed filter. Dual-band versions of this radio also can change channels, but the orientation of low-side or high-side transmit must be retained. That is, an Al radio can only be changed into a B1 radio with a new filter, but not into an A2 or a B2. Likewise, the A2 radio can only be changed into a B2 radio with a new filter, but not into an Af or B1. The diplexer filters can goon any radio and must be properly oriented. After filter is changed, the frequency setting within the configuration menu

(NMS) must be changed to match the installed filter. Or eee PAGE 4-2 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY .

Far-End radio transmitter circuitry is faulty ed Near-End radio receiver circuitry is faulty

* Link security ID not the same for each radio Recommended Actions:

Check the following at each end of the link:

* Verify that rear panel fiiters are opposite channel plans on each end (e.g. one is A1 and other is A2). Verify that radio frequency settings match each instailed filter (in NMS menus).

* Verify that ail connections between radios and antennas are secure and all devices between radios and antennas are rated for the radio frequency band (5.3/5.8 GHz). Measure RSL by placing a voltmeter across RSL and GND test points. Compare this voltage to the Factory Test Data Sheet and estimate the RSL in dBm. Compare this to the RSL that was expected using path calculations (see Section 3.3.3}. Press and hold the DISPLAY FAR END button and measure the far-end RSL (while continuing to hold the button). Compare this RSL to the Factory Test Data Sheet for the far-end radio and estimate the RSL in dBm. Again, compare this RSL to the expected RSL from the link budget calculations. lf RSL from both ends of the radio are approximately the same as each other, but lower than anticipated for this installation, then the likely cause of the BER alarm(s} is excessive losses between the radios. Excessive loss problems could include the transmission line at either end, all adapters, connectors, the antennas, the antenna alignment as well as the path itself (any obstructions or clearance problems). Antenna alignment, line-of-sight and path clearance shouid be verified; if this does not improve ASL, all devices between the radios and their antennas at both ends should be checked. Make sure ail transmission fine, connectors and any other devices eee SECTION 4: TROUBLESHOOTING PAGE 4-7 Tsunami FAMILY WES TE RN FAST ETHERNET WIRELESS BRIDGES

; INSTALLATION AND MAINTENANCE MANUAL Multiplex JULY 2000 are properly rated for operation at the radio's frequency (5.3/5.8 GHz). If only one end has low RSL, this could be caused by low transmit output power from the opposite end radio. Verify that the transmitter output power of the radio opposite to the low RSL receiver has been set in accordance to path calculations, or EIRP restrictions (where applicable). Power adjustment must be performed by professional installation personne! only. The PWR test point can be used and compared with the Factory Test Data Sheet, the front panel recessed patentiometer can be turned clockwise to increase power. If an RF power meter is available, this can be connected to the RF output of the radio for precision measurement. This test will also verify that the radio transmitter is working properly. If one terminal (or both) has high RSL, this could be caused by a very short path or interference, To verify the possible presence of interference, remove DC power to the radio which is opposite to the one that is reading high RSL. Once power is removed, measure RSL on the remaining radio. If RSL voltage is lower than that which is listed for "Threshold" in the Factory Test Data Sheet, then an interfering signal is present. If interference is suspected, the easiest potential remedy is to swap frequency channels on both sides of the link. See Section 4.2 for details. Swap terminals at both ends of the link so that they are the opposite from their original installation. After both ends are moved, reconnect the radios and determine if the BER alarm is still active. If the BER alarm is Still active, other frequency channels can be installed, or other interference countermeasures can be tried, in accordance with Section 4.8. If all path retated and data input problems have been pursued and the BER alarm is still active, the probiem could be related to a radio failure. While radio failure is typically indicated by more severe alarm conditions, it is possible that one of the radios may be out of specification, and this Could be the cause of the BER alarm. A back-to-back test will verify proper radio operation. See Section 4.9 for details. A threshold test on both radios along with a test to verify proper RF output power would be beneficial. Perform a back-to-back test before returning any radio terminal to

@ the factory for repair. A back-to-back test verifies radio operation.

(See Section 4.9). If the radios successfully pass their back-to-back testing, the probiem is likely with the path or the connections between the radio and the antenna or interference. Before reinstalling the radios, be Sure to set the output power to the appropriate level for the installation.

FAST ETHERNET WIRELESS BRIDGES we 5 TERN JULY 2000 Multiplex 4.7 Errors in the Data Stream When the radio is in service, errors in the data stream may occur. This is usually known to the operator by either faulty data indications of downstream equipment or external bit error rate testing. it is possible that no alarms appear on the front pane! during normal operations, but there are errors present in the data stream. Some errors will not result in no alarm (such as bipolar violations, slow dribbling errors, improperly terminated connections or incorrect settings), but will be exhibited on downstream data processing equipment or during a BER test. In other cases, there may be data errors due to atmospheric conditions (fading), interference or other reasons, but not at a high enough error level to be indicated with the BER alarm LED. in the case of these types of errors, the following information can be helpful to troubleshoot the radio fink. Indications:

* During external BER test, test equipment indicates errors

* Downstream equipment (mux, channel bank, CODEC, router, atc.) indicates errors Possible Causes:

* Path fading due to atmospheric conditions

* Poor transmission fine connections

* Antenna problems, misalignment or path clearance

* Received signal jevel (RSL) is too strong

* Far-End radio transmitter circuitry is faulty

* Near-End radio receiver circuitry is faulty

% ~~ Interference Recommended Actions:

1. Verify 100BaseT wiring. 2. Follow the instructions described in Section 4.6.1 rr SECTION 4; TROUBLESHOOTING PAGE 4-11 Tsunami FAMILY WESTERN FAST ETHERNET WIRELESS BRIDGES INSTALLATION AND MAINTENANCE MANUAL Multiplex JULY 2000 4.8 Interference Countermeasures The recommended interference countermeasures available to the Tsunami operator are as follows:

1 Short Paths The single most effective countermeasure against interference is to maintain short path" length, This may be achieved by dividing long paths into multiple small paths by cascading hops. Intermediate repeaters may be formed using back-to-back Tsunami terminals and transmit output power reduced, if required. By definition, "short path" is defined as a path where fades are extremely rare and signal levels vary by no more than +3 dB during fades. This distance will vary with the RF frequency. Typically a "short path" is defined as any path length shorter than 5 miles at 5.3/5.8 GHz. 2, Narrow Beam Antennas (high gain}

This is the next most effective countermeasure. Narrow beam antennas ensure that the transmitted power is sent in a single direction and this minimizes the possibility of causing interference inadvertently to other users. Narrow beam antennas also reject off-azimuth signals being received from potential sources of interference and have high gain which boosts desired receive levels and improves the carrier to interference ratio. When selecting narrow beam antennas, it is helpful to know that larger antennas generally outperform smaller antennas. Another important antenna specification is the front-to-back ratio which ensures rejection of unwanted signals from azimuth angles behind the antenna. 3. Frequency Selection This is another very effective countermeasure. The Tsunami radio offers several distinct non-

overlapping frequency channel plans (see Sections 3.5 and 4.2) and the radios RF filter is able to reject interference more than 10 MHz away from the receive frequency. Offset frequencies combined with other countermeasures may enabie several receive channels to operate at a single hub site. Because of the limited spreading ratio used, frequency selection is more efficient than code selection for interference rejection when operating multiple Tsunami terminals at a single Site. Interference can often be overcome by exchanging frequencies of both-ends of the radio link

(e.g. change your A1 terminal to an A2 and change the other end from an A2 to an A1}. Also, changing channel pians (e.g. from A to B) can be very effective. (See Section 4.2). rrr oO PAGE 4-12 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY . FAST ETHERNET WIRELESS BRIDGES WE 5 TERN JULY 2000 Multiplex 4. Antenna Polarization Cross-polarized antennas can provide approximately 20 to 30 dB discrimination of unwanted signals. The actual discrimination will depend upon the antenna design and any rotation of polarization along the path, for example, due to reflections. Discrimination only exists between two orthogonal polarizations:

- vertical vs. horizontal or

- left-pand circular vs. right-hand circular There is only 3 dB discrimination between circular and linear (vertical or horizontal) polarization. interference can sometimes be overcome by changing antenna polarization at both ends of the link, 5. Transmit Power The maximum Jevel into the receiver is -30 dBm. Above this level, errors may occur in the receive data stream. Transmit output power should be reduced on very short paths to avoid overload, 6. Equipment/Antenna Location Occasionally, interference is caused by the radio or the antenna being too close to another similar transmitter. Moving the radio, the antennas, or the interfering equipment can reduce or eliminate interference. ke interference countermeasures rely {fo some extent on the . y: measurement of the received interference fevel and frequency.

, . Prior to turning up a new hop, a spectrum analyzer can be used to moniter the spectrum at each end to check for possible interfering signals. See Section 4.8.1 for more details. SECTION 4: TROUBLESHOOTING PAGE 4-13 G INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY WESTERN FAST ETHERNET WIRELESS BRIDGES Multiplex JULY 2000 4.8.1 Use of a Spectrum Analyzer to Evaluate Potential Interference Connecting to the antenna and using peak hold" on a spectrum analyzer, the spectrum across the receive frequency range of the radio can be swept and any signals being received at levels above the radios specified threshold identified. 'f potential interfering signals are found, then the Tsunami frequency plan can be changed to avoid a receive channel which may contain significant interlerence (see Section 4.2). For example, interference may be reduced by moving from the A1/A2 pian to the B1/B2 plan or by swapping terminals or RF filters so that A1 becomes A2. wy Signals outside the receiver frequency range may be ignored:

Ay they will nol cause interference. lf a spectrum analyzer is not available, the RSL voltage can be used to indicate the background noise and interference level within the receiver AF filter band when the far-end transmitter is turned off. With the far-end radio turned off, if an ASL voltage level below the radio's threshold level is measured, there is potentially interference in this frequency channel. When using a spectrum analyzer for determining the presence of interference, very narrow resolution bandwidth settings must be used to detect signals down to the radio's threshold

(approximately -80 dBm, depending on radio type). rt PAGE 4-14 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY . FAST ETHERNET WIRELESS BRIDGES WESTERN JULY 2000 Multiplex 4.9 Back-fo-Back Testing Back-to-back testing, as shown in Figure 4-1, is an ideal method of testing the Tsunami radios. This testing eliminates link problems caused by auxiliary equipment, instailation, or the radio path and isolates potential radio hardware problems. Back-to-back testing must be performed with both radios at the same location. The following test equipment is required:

** DC power source capable of supplying approximately 90 Watts (total) to the radios (or two AC adapters) One low-loss coaxial cable, N-to-N male

* One (or more} coaxial in-line calibrated fixed attenuators, 40 to 80 dB total attenuation The following test equipment may also be useful to perform further testing of the Tsunami radio:

+ BER tester

* Variable (60 dB range or more) RF attenuator (rated for the proper frequency, 2.4 or 5.8 GHz)

+ RF power meter Back-to-back testing must be performed to verify a radio problem before returning any radio to the factory for repair. When the equipment is connected as shown in Figure 4-1, both Tsunami radios shauld have no alarm conditions. If these conditions have been met, then it is likely that the Tsunami radio is operating in accordance to specifications. If errors or alarms occur during this test, verify that ail DIP switch settings are properly set. If alarms or errors are still present, the radio is likely to be faulty. If further troubleshooting is required, a variable RF attenuator can be inserted between the radios to fade down the path to determine that the threshold specification is being met. The threshoid tests can be run in both directions to isolate the radio problem (if any}. More information testing is provided in Section 4.10. An RF power meter can be used to individually test each radios output power. rere SECTION 4; TROUBLESHOOTING PAGE 4-15 Tsunami FAMILY WESTERN FAST ETHERNET WIRELESS BRIDGES

It can be performed from end-to-end or in link test mode {which tests both directions of the radio path). Figure 4-2 illustrates a typical test configuration (which may include the radio's path instead of in-line attenuators). Figure 4-2 illustrates a typical test configuration for end-to-end testing. When performing testing, make sure of the following:

- Disconnect all 100BaseT inputs and outputs to both radios.

- Verify all configuration settings. Link testing may be performed on the bench, with two terminals back to back, or over the radio path. Also, it may be performed from end-to-end (which requires two 100BaseT test sets over a link, the far-end unit slaved to the near-end unit's clock) or in loopback mode, as described in Section 4.9. if link testing indicates an unacceptable level of errors, follow the instructions in Section 4.6.1. or perform a back-to-back test as described in Section 4.9.

The NMS port can have a unique domain that is valid only with the PC thal is being used for network management and system-wide operational status and will not interfere with 100BaseT traffic as the radio's MAC address plus its 1P address are unique. Radios are set at the factory to IP addr: 10.0.0.1. Temporally set your PCs domain (write down its present IP address) to a suggested setting of PC=10.0.0.5-the PC will force a re-boot. Re-boot the PC computer attached to the first radio's 10BaseT NMS port and jog-in to radio NMS wfavorite browser (IE or Netscape) after log-in (manager:manager). Change the IP address

Do the same with other radio (may have to reboot computer attached to this other 10.0.0.1 radio as the other's MAC address does not match the MAC/IP address the PC knows about}. Set the IP address this radio to a different iP address in your normal operating domain. Set your PC back to its original domain (will force reboot again).

A: Ethernet is a type of network cabling and signaling specifications (OS! Mode! layers 1

[physical] and 2 [data fink]} originally developed by Xerox in the late 1970. The IEEE's

(Institute of Electrical and Electronics Engineers) used Ethernet Version 2 as the basis for the 802.3 CSMA/CD network standard Q: What is an 802.3 network?

A: That's IEEE-ish for Ethernet. Q: What is CSMA/CD?

A: CSMA/CD is the media access control mechanism used by Ethernet and 802.3 networks, in other words, it determines how a packet of data is placed on the wire. CSMA/CD stands for "Carrier Sense Multiple Access, with Collision Detection". Before an Ethernet device puts a packet on the wire", it listens to find if another device is already transmitting. Once the device finds the wire is clear, it starts sending the packet while aiso listening to hear if another device started sending at the same time (which is called a collision). Refer to the Q&A on collisions for more info about this phenomena.

@: What is an OS! Model?

A: The Open Systems Interconnect (OS!) reference model is the !SO (International Standards Organization) structure for the "idea!" network architecture. This Model outlines seven areas, or layers. for the network. These layers are (from highest to lowest). LAYER 7) Applications: Where the user applications software lies. Such issues as file access and transfer (FTP), virtual terminal emulation. Internet connections (HTTP}, inter-

process communication and the like are handied here. 6) Presentation: Differences in data representation are dealt with at this level. For example, UNIX-style line endings (CR only} might be converted to MS-DOS style

(CRLF), or EBCIDIC to ASCII character sets 5) Session: Communications between applications across a net- work is controlled at the session layer. Testing for out-of-sequence packets and handling two-way communication are handied here. 4) Transport: Makes sure the lower three layers are doing their job correctly, and provides a transparent. logical data stream between the end user and the network service s/he is using. This is the lower layer that provides local user services. 3) Network: This layer makes certain that a packet sent from one device to another actually gets there in a reasonable period of time. Routing and flow control are performed here. This is the lowest layer of the OSi model that can remain ignorant of i SECTION 5: APPENDICES PAGE 5-3 INSTALLATION AND MAINTENANCE MANUAL

Tsunami FAMILY WESTERN FAST ETHERNET WIRELESS BRIDGES Multipiex JULY 2000 the physical network 2) Data Link: This layer deals with getting data packets on and off the physical layer. error detection and correction and retransmission. This layer is generally broken into two sub-layers: The LLC (Logical Link Control} on the upper half, which does the error checking, and the MAC (Medium Access Control) on the lower half, which deais with getting the data on and off the physical layer (wire, fiber and Tsunami Wireless Bridges). 1) Physical: The nuts and bolts layer. Here is where the cable, fiber, radio, connector and signaling specifications are defined. Q: What does an Ethernet packet look like?

PAGE 5-4 SECTION 5: APPENDICES Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES JULY 2000 WESTERN INSTALLATION AND MAINTENANCE MANUAL

( Multipfex A: It is the unique hexadecimal (numbering base 16) serial number assigned to each Ethernet network device to identify it on the network.. With Ethernet devices {as with most other network types}, this address is permanently set at the time of manufacturer, though it can usually be changed through software (though this is generally a Very Bad Thing to do}. Q: Why must the MAC address fo be unique?

A: Each communicating end device (not bridges) has a unique MAC address. so that it will be able to exclusively grab packets off the network meant for it IF MAC addresses are not unique, there is no way to distinguish between two devices. Devices on the network watch network traffic and look for their own MAC address in each packet to determine whether they should decode it or not. Special circumstances exist for broadcasting to every device. Q: Is there a special numbering scheme for MAC addresses?

A: The MAC addresses are exactly 6 bytes in length, and are usuaily written in hexadecimal as 12:34:56:78:90:AB (the colons may be omitted, but generally make the address more readable}. Each manufacturer of Ethernet devices applies for a certain range of MAC addresses they can use. The first three bytes of the address determine the manufacturer. RFC-1700 (available via FTP) lists some of the manufacturer-assigned MAC addresses. A more up-to-date fisting of vendor MAC address assignments is available on ftp.Ics.mit.edu in pub/map/Ethernet-codes. Q: What does CRC mean?

A: Cyclical Redundancy Check - A method of detecting errors in a message by performing a mathematical caicuiation on the bits in the message and then sending the results of the calculation along with the message. The receiving work-station performs the same calculation on the message data as it receives it and then checks the results against those transmitted at the end of the message. If the results don't match, the receiving end asks the sending end to send again. Q: What do 10Base5, 10BaseT, 10Base2, etc mean?

A: These are the IEEE names for the different physical types of Ethernet. The "10" stands for maximum signaling speed: 10MHz. Base means Baseband. 10BaseT, where the T means twisted pair, and 10BaseF where the F means fiber (see the following Q&A for specifics). This actually comes from the IEEE committee number for that media. In actual practice:

10Base2 Is a maximum of 10MHz Ethernet running over thin. 50 Ohm baseband coaxial cable. 10Base2 is also commonly referred to as thin-Ethernet or Cheapernet. 10Base5 is 10MHz Ethernet running over standard (thick) 50 Ohm baseband coaxial cabling. 10BaseF is Ethernet running over fiber-optic cabling. 10BaseT is Ethernet running over unshielded, twisted-pair cabling. Q: What is UTP?

er SECTION 5: APPENDICES PAGE 5-5 Tsunami FAMILY WESTERN FAST ETHERNET WIRELESS BRIDGES

( INSTALLATION AND MAINTENANCE MANUAL Multiplex JULY 2000 A: Twisted pair cables. UTP is for Unshielded, Twisted Pair, while STP is for Shielded, Twisted Pair. UTP is what's typically installed by phone companies (though this is often not of high enough quality for high- speed network use) and is what 10BaseT Ethernet runs over. UTP is graded according to its data carrying ability (e.g., Level 3, Level 4, Level 5). 10BaseT Ethernet requires at least Level 3 cable. Many sites now install only Level-5 UTP (CATegory 5), even though level 4 is more than sufficient for 10BaseT, because of the greater likelihood that emerging high-speed standards will require cable with better bandwidth capabilities. Q: Are there any restrictions on how Ethernet is cabled?

A: Yes, there are many, and they vary according to the media used. First of all, there are distance limitations: }OBaseT generally accepted to have a maximum run of 100-150M, but is really based on signal loss in dB's (11.5db maximum loss source to destination}

Then there are limitations on the number of repeaters and cable segments allowed between any two stations on the network. The rule is, any possible path between two network devices on an unbridged/unrouted network cannot pass through more than 4 repeaters or hubs, nor more than 3 populated cable segments. 10BaseT and 10BaseF are star-wired, so there is no minimum distance requirement between devices, since devices cannot be connected serially. You can install up to the Ethemet maximum of 1024 stations per network with both 10BaseT and

{0BaseF. Q: When should | choose 10BaseT, 10BaseF (or others)?

A: The specific environment and application must be considered when selecting your media type. However, there are some general rules-of-thumb that you can consider:

Avoid using copper between buildings. The electrical disturbances caused by lightning, as well as naturally occurring differences in ground potential over distance, can very quickly and easily cause considerable damage to equipment and people. The use of fiber-optic cabling between buildings eliminates network cabling as a safety risk. There are also various wireless media available for inter-buiiding links, such as laser. spread-spectrum RF and microwave. 10BaseT is the most fiexible topology for LANs, and is generally the best choice for most network installations. 10BaseT hubs, or multi-hub concentrators, are typically installed in a central location to the user community, and inexpensive UTP cabling is run to each network device (which may be 100m, or 330ft, from the hub}. The signaling technology is very reliable, even in somewhat noisy enviranments, and 10BaseT hubs will usually detect many network error conditions and automatically shut-down the offending port(s) without affecting the rest of the network (unless, of course, the offending port was your server, shared printer, or router to the rest of the world. 10BaseF, and its predecessor, FOIRL, are the only recommended topologies for inter-

building links. However, they need not be limited to this role. 10BaseF can also be run to the desktop, though the cost is prohibitively high in all but the most specialized environments (generally, extremely noisy manufacturing facilities, or very security-

Multiplex conscious installations). More commonly, FOIRL (and now, 10BaseF) is used inside buildings and long distance wireless connections to form backbone networks. Q: Is there an official "standard" punch down scheme for 10BaseT?

A: Get a copy of EIA/TIA-568, it covers all of that sort of stuff: horizontal. vertical, connectors, patch cords, cross-connects. etc. Q: Is it safe to run Unshield Twisted Pair next to power cable?

A: According to EIA/TIA-569, the standard wiring practices for running data cabling and companion to the above referenced EIA/TIA-568, you should not run data cable parallel to power cables. However, in reality. this should not be a problem with networks such as 10BaseT. 10BaseT uses differential signaling to pick the data signals off the wire. Since any interference from nearby power lines will usually affect all pairs equally, anything that is not canceted-out by the twists in the UTP should be ignored by the receiving network interface. Q: Can | connect the 10BaseT interface of two devices directly together, without using a hub?

A: Yes, but not more than 2 devices, and you also need a special jumper cable between the two 10BaseT ports:

mh tw Roe Q: What is a "segment"?

A: A piece of network wire bounded by bridges, routers, repeaters or terminators.

@ What is a "subnet"?

A: Another overloaded term. it can mean, depending on the usage, a segment, a set of machines grouped together by a specific protocol feature (note that these machines do not have to be on the same segment, but they could be} or a big nylon thing used to capture enemy subs Q: What is a repeater?

A Arepeater acts on a purely electrical level to connect to segments. Ail it does is amplify and reshape (and, depending on the type, possibly retime) the analog waveform to extend network segment distances. it does not know anything about addresses or forwarding, thus it cannot be used to reduce traffic as a bridge can in the example above. Q: What is a "hub"?

SECTION 5: APPENDICES PAGE 5-7 Tsunami FAMILY WESTERN FAST ETHERNET WIRELESS BRIDGES

( INSTALLATION AND MAINTENANCE MANUAL Multiplex JULY 2000 A: A hub is a common wiring point for star-topology networks, anc is a common synonym for concentrator (though the latter generally has additional features or capabilities). 10BaseT and 10BaseF Ethernet and many proprietary network topologies use hubs to connect multiple cable runs in a star-wired network topology into a single network. Hubs have multiple ports to attach the different cable runs. Some hubs {such as 10BaseT} include electronics to regenerate and retime the signa! between each hub port. Others (such as 10BaseF} simply act as signal splitters, similar to the multi-tap cable-TV splitters you might use on your home antenna coax (of course, 10BaseF uses mirrors to split the signals between cables). Q: What is a bridge?

A. A bridge will connect to distinct segments and transmit traffic between them. This allows you to extend the maximum size of the network while still not breaking the maximum wire length, atiached device count, or number of repeaters for a network segment. Q: What does a "learning bridge"?

A. A learning bridge monitors MAC (OSI layer 2) addresses on both sides of its connection and attempts to learn which addresses are on which side. It can then decide when it receives a packet whether it should cross the bridge or stay local (some packets may not need to cross the bridge because the source and destination addresses are both on one side}. if the bridge receives a packet that it doesnt know the addresses of, it will forward it by default. IEEEs standard for a learning bridge is 802.1D. Q: Is there a maximum number of bridges allowed on a network?

A: Per {EEE 802.1 {d), the maximum number of concatenated brides in a bridged LAN is 7. This number is rather arbitrary, however, and is based on simulations of application performance with expected bridge delays. In addition, the number assumes that all bridges are LOCAL (no remote WAN connections}, and that the default Hold Time of 1 second is in place (this is the time after which a bridge will discard a frame it is holding). This prevents extra-late frame delivery. (i.e, a frame should never be delivered more than ~7 seconds after is it sent). The rule of thumb for wireless WAN bridged LANs is to limit the number of hops to 4. Q: What is a router?

A: Routers work much like bridges, but they pay attention to the upper network layer protocols (OSI layer 3} rather than data link layer (OSI layer 2) protocols. A router will decide whether to forward a packet by jooking at the protocol Jevel addresses (for instance, TCP/IP addresses) rather than the MAC address. Because routers work at layer 3 of the OSI stack, it is possible for them to transfer packets between different media types {i.e., leased lines, Ethernet, token ring, X.25, Frame Relay and FDDI). Many routers can also function as bridges. PAGE 5-8 SECTION 5: APPENDICES INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY . FAST ETHERNET WIRELESS BRIDGES WE 5 TERN Multiplex JULY 2006 Q: So should | use a router or a bridge?

A: There is no absolute answer to this. Your network layout, type and amount of hosts and traffic, and other issues (both technical and non-technical} must be considered. Routing would always be preferable to bridging except that routers are slower and usually more expensive (due to the amount of processing required to look inside the physical packet and determine which interface that packet needs to get sent out), and that many applications use non-routable protocols. Rules of thumb:

Bridges are usually good choices for small networks with few, if any, slow redundant links between destinations or for connecting distant LANs. Further, bridges may be your only choice for certain protocols. unless you have the means to encapsulate {tunnel} the un-

routable protocol inside a routable protocol. Routers are usually much better choices for larger networks, particularly where you want to have a relatively clean WAN backbone. Routers are better at protecting against protocol errors (such as broadcast storms) and bandwidth utilization. Since routers look deeper inside the data packet, they can also make forwarding decisions based on the upper-layer protocols. Occasionally, a combination of the two devices are the best way fo go. Bridges can be used to segment small networks that are geographically close to each other, between each other and the router to the rest of the WAN. Q: Are there problems mixing Bridging & Routing?

A: Only if you plan on having bridged links in parallel with routed links. You need to be very careful about running bridges providing links in parallel to a router. Bridges may forward broadcast requests which will confuse the router there are iots of protocols you may not think of filtering (e.g. ARP, Apple ARP over 802.3 etc. etc.). Also, DECnet routers have the same MAC address on all ports. This. will probably cause the bridge to think it is seeing an Ethernet loop. Q: Who makes the fastest/easiest/most advanced bridges or routers?

A: The IETF runs bench marks on a wide selection of wired/fiber bridges and routers. Network Computing runs bench marks for wireless routers (point-to-multipoint) and bridges (point-to-point). Q: What does "IPG" mean?

A: The InterPacket Gap {more properly referred to as the InterFrame Gap, or IFG) is an enforced quiet time of 9.6 us between transmitted Ethernet frames. Q: What means "promiscuous mode"?

A: Promiscuous mode is a condition where the network interface controller wiil pass all Ethernet frames. regardless of destination address, up to the higher level network layers. SECTION 5: APPENDICES PAGE 5-9 Tsunami FAMILY WESTERN FAST ETHERNET WIRELESS BRIDGES

( INSTALLATION AND MAINTENANCE MANUAL Multiplex JULY 2090 Normally the network controller will only pass up frames that have that device's destination address. However, when put in promiscuous mode, all frames are passed on up the network stack regardless of destination address. Promiscuous mode is usually used by network monitoring tools and transparent bridges. Q: What Is a collision?

A: A condition where two devices detect that the network is idle and end up trying to send packets at exactly the same time (within 1 round-trip delay}. Since only one device can transmit at a time, both devices must back off and attempt to retransmit again. The retransmission algorithm requires each device to wait a random amount of time, so the two are very likely to retry at different times, and thus the second one will sense that the network is busy and wait until the packet is finished. If the two devices retry at the same time (or almost the same time} they will collide again, and the process repeats until either the packet finally makes it onto the network without collisions, or 16 consecutive collision occur and the packet is aborted. Q: What causes a collision?

A: See above. Ethernet is a CSMA/CD (Carrier Sense Multiple Access/ Collision Detect}

system. It is possible to not sense carrier from a previous device and attempt to transmit anyway, or to have two devices attempt to transmit at the same time: in either case a collision results. Ethernet is particularly susceptible to performance loss from such problems when people ignore the "rules" for wiring Ethernet. Q: How many collisions are too many?

A: This depends on your application and protoco!. In many cases, collision rates of 50% will not cause a large decrease in perceived throughput. If your network is slowing down and you notice the percentage of collisions is on the high side, you may want try segmenting your network with either a bridge or router to see if performance improves. Q: How do | reduce the number of collisions?

A: Disconnect devices from the network. Seriously, you need to cut- down on the number of devices on the network segment to affect the collision rate. This is usually accomplished by splitting the segment into two pieces and putting a bridge or router in between them. Q: What is a late collision?

A: A late collision occurs when two devices transmit at the same time, but due to cabling errors {most commonly, excessive network segment length or repeaters between devices) neither detects a collision. The reason this happens is because the time to propagate the signal from one end of the network to another is tonger than the time to put the entire packet on the network, so the two devices that cause the late collision never see that the other's sending until after it puts the entire packet on the network. Late collisions are detected by the transmitter after the first "slot time" of 64 byte times. They PAGE 5-10 SECTION 5; APPENDICES INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES . WESTERN JULY 2000 Multiplex are only detected during transmissions of packets longer than 64 bytes. It's detection is exactly the same as for a normal collision: it just happens "too late."

Typical causes of late collisions are segment cable lengths in excess of the maximum permitted for the cable type. faulty connectors or improper cabling, excessive numbers of repeaters between network devices, and defective Ethernet transceivers or controllers. Another negative concerning late collisions is that they occur for small packets also, but cannot be detected by the transmitter. A network suffering a measurable rate of late collisions (on large packets} is also suffering lost small packets. The higher protocols do not cope well with such losses. Well, they cope, but at much reduced speed. A 1% packet loss is enough to reduce the speed of NFS by 90% with the default retransmission timers. That's a 10 times increase of the problem!

Finaily, Ethernet controllers do not retransmit packets lost to late collisions. a Q: What is a jam?

A: When a workstation receives a collision, and it is transmitting, it puts out a jam so all other stations will see the collision also. When a repeater detects a collision on one port, it puts out a jam on all other ports. causing a collision to occur on those lines that are transmitting, and causing any non-transmitting stations to wait to transmit. Q: What is a broadcast storm?

A: An overloaded term that describes an overloaded protocol. Basically it describes a condition where devices on the network are generating traffic that by its nature causes the generation of even more traffic. The inevitable result is a huge degradation of performance or complete loss of the network as the devices continue to generate more and more traffic. This can be related to the physical transmission or to very high jevel protocols. Q: How do | recognize a broadcast storm?

A: That depends on what level it is occurring. Basically you have to be aware of the potential for it beforehand and be looking for it, because in a true broadcast storm you will probably be unable to access the network. This can change dramatically for a higher level protocol. NFS contention can result in a dramatic DROP in Ethernet traffic, yet no one will have access to resources. Q@: How can | prevent a broadcast storm?

A: Avoid protocols that are prone to it. Route (with routers} or Bridge (with wired/wireless bridges) when it is practical. Q: What is *high traffic on an Ethernet? 5%? 20%? 90%?

A. High traffic is when things start slowing down to the point they are no longer acceptable There is not set percentage point, in other words. Usually start paying attention when it SECTION 5: APPENDICES PAGE 5-11 Tsunami FAMILY WESTERN FAST ETHERNET WIRELESS BRIDGES

( INSTALLATION AND MAINTENANCE MANUAL Multiplex JULY 2000 gets over 40-50%. Q: Why do I see different throughput speeds?

A: Bridges (such as Tsunami) are ISO Layer 2 Data Link Layer (use MAC address for filtering) devices where they provide their full stated throughput. At level 2 (bridges) or 3

{routers} where hardware plays the major part, the most common tester is the SmartBits 200 product from NetCom Systems. At Application Layer 7, you will see less than 40%

throughput from the maximum capacity measured w/SmartBits due to the increased protocol/software overhead at that level. Layer 7 can be tested with software such as Ganymedes Chariot or Qcheck product. As an example: testing copper CATS cable with SmartBits will test 100% throughput (let's say you can send/rcv a full 10Mbps). At Layer 7 you will be transferring data at the 10Mbps rate. but only 4Mbps of user data will transfer (Ethernet has a high overhead of bytes added to each data packet each time you go up a layer). The advantage is the more complex overhead makes the data virtually resilient to corruption and minor errors (i.e. collisions), its easy to reroute and can use inexpensive plug/play devices like hubs/switches instead of multiplexers as used in the telco industry (i.e. LYNX T1 radios) Westem Multiplex tests at Layer 2 where bridges are defined. At layer 7 (Application Layer), you will see less than 40% or more depending on the other traffic that may be on the LAN as this layer is more dependent on the type of data being sent (it does not matter if it's wire, fiber or any Ethernet bridge -wired or wireless). Another way to look at it: the model 31145 12Mbps (10Mbps 10BaseT+T1/E1 wayside) bridge will test the same as a piece of CATS Ethemet cable. Q: How can | test an Ethernet?

A: This depends on what level you want to test. The most basic test (a.k.a., "the fire test") is to connect a pair of devices to the network and see if they can communicate with each other. If you want to test the electrical integrity of the wire (i.e., will it carry 2 signal properly}, a TDR or cable scanner that incorporates TDR and other functions. would be the most comprehensive tool. If you need to test the performance or troubleshoot protocol transmission problems, you will need special and usually very expensive software, usually coupled with custom hardware, to capture, optionally filter, and analyze the network packets. Also, see the answer to the question above. Q: What is a "TDR"?

A: A Time-Domain Reflectometer is a tool used to detect cable faults. This device operates by sending a brief signa! puise down the cable and looking for its reflection to bounce back. By analyzing the reflected pulse, it is possible to make judgments about the quality of the cable segment. More advanced units can not only detect and identify the nature of the problem, but give a reasonably accurate indication of the problem's iocation (distance from the point of the test). There is also a device known as an OTDR, which is an Optica!

Time-Domain Reflectometer for fiber-optic cables. Q: What is a "BERT'?

A. There are many built into most DOS Unix and other operating systems. For example, the ping command can be used to determine if a given host is alive, and will aiso tell you the round trip transmission time. The command ifconfig will tell you the status of the network interfaces. netstat will summarize statistics for network usage. DOS commands (through Windows DOS application) are:

ARP Displays and modifies the IP-to-Physical address translation tables used by address resolution protocol (ARP}. ARP -a [inet_addr] [-N if_addr]

a Displays current ARP entries by interrogating the current protocol data. If inet_addr is specified, the IP and Physical addresses for only the specified computer are displayed. If more than one network interface uses ARP, entries for each ARP table are displayed.

-g Same as -a. inet_addr Specifies an internet address.

-Nif_Laddr Displays the ARP entries for the network interface specified by if_addr

-d Deletes the host specified by inet_addr. Ss Adds the host and associates the Internet address inet_addr with the Physical address eth_addr. The Physical address is given as 6 hexadecimal bytes separated by hyphens. The entry is permanent. eth_addr Specifies a physical address. if_addr If present, this specifies the Internet address of the interface whose address translation table should be modified. If not present, the first applicable interface will be used. Example:

> arp -s 157.55.85.212 00-aa-00-62-c6-09 .... Adds a static entry.

>arp-a .... Displays the arp table. FTP Transfers files to and from a computer running an FTP server service (sometimes called 2 daemon). FTP can be used interactively. FTP [-vj [-d] [-i] [-n] [-g] [-s:filename] [-a] [-w:windowsize] [-A] [host]
