SECTION 1: HOW TO USE THIS MANUAL PAGE 1-5 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 2. Product Description 2.1 General Description The Tsunami communications network. license-free radios provide a new level of control and convenience in a digital These Tsunami radios provide 100BaseT intelligent bridging between two locations without the delay and expense of installing cable or traditional microwave. Because each owner controls 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:

v CONVENIENCE to install and operate with no user Easy license requirements or frequency coordination in the USA. (Other countries may require a user license and/or frequency coordination). v CAPABILITY transparent Fast Ethernet connections with no Full 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 CAT5 cable with SmartBits will test 100% throughput (let's say you can send/rcv 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 CAT5 Ethernet cable.

The IP address for the NMS port will now be available through the radios DATA ports. This must be done on both ends of the bridge link. Note: Multicasting with in-band connection may cause collisions in the data stream. 2.3.2 Test Points / Power Indicator ON GND RSL LOCAL TX PWR

. This is an LED indication. When lit GREEN, Tsunami is powered. The Tsunami radio products do not have an on/off switch. 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. Note: The ground lug on the Model 28010 ODU must be properly connected to earth ground. 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 FAR 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. RSL is located on the Model 28010 ODU with a weather protected BNC connector. 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 (software controlled on Model 28010 with ODU transceiver) 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. Not available on models with ODU component. The Tsunami system requires professional installation. Transmitted output power limits may apply when using this radio.

When pressed and held, the alarm and status LEDs and the RSL test point

(except for the Model 28010 with ODU) correspond to the far-end radios status and RSL value. 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. SECTION 2: PRODUCT DESCRIPTION PAGE 2-13 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 2.3.6 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 at 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 for operation, but provide additional facilities to the user. EOW VF 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. 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. This circuit is 4-wire audio (2xTx and 2xRx) 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. PAGE 2-14 SECTION 2: PRODUCT DESCRIPTION INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 CONFIG 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 connected computer or terminal. Consult factory for operation. 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. 10BaseT NMS This is an Ethernet connection for access to the Tsunami NMS (SNMP or HTML). See section 4.11 for more detail for operation. Note: Multicasting with in-band connection may cause collisions in the data stream. T1 E1 This is a wayside data channel for T1 (DS-1) interface of auxiliary traffic (2XXX0-51 Models). This is a wayside data channel for E1 (CEPT-1) interface of auxiliary traffic (2XXX0-52 Models).

v This manual v Installation accessory kit (see Section 2.5) PAGE 3-2 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 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 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 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 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 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 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. 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 Pout - FL1+ G1 by the EIRP limit. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-5 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 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 (5.3 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 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 in conjunction with lower loss feeders (by using high quality transmission line or shortening feed length). PAGE 3-6 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 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 should 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 plan (e.g. A versus B). However, with careful engineering, placing more than one radio of the same frequency channel plan at the same site is easily accomplished. In fact, the Tsunami frequency plan 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 A1) should be used at a site to minimize interference. Using alternate channels (e.g. A1 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. Section 4.8 of this manual describes interference countermeasures in further detail. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-7 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 3.3.7 Power Supply Planning The Tsunami radio 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 Antenna Planning Using the path planning tools and equations presented in the Product Guide, proper antenna size can be determined which will yield the desired path performance. In general, the larger the antenna that is used with the 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 an antenna. Consult the Product Guide for more details on selecting antennas. Recommended Antenna Size 2 ft 4 ft 6 ft 8 ft 10 ft Gain / 3 dB Beam Width 29 dB / 6 35 dB / 3 38 dB / 2 41 dB / 1.5 43 dB / 1.3 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 directional antennas may be used with these radios.

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 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. PAGE 3-12 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 3.7 Power Connection and Wiring (Models w/o ODU) There is no ON/OFF switch on the Tsunami. 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-A or 3-B along with the associated diagram of Figure 3-4 or 3-5 to connect the DC power cables. For example, for a negative DC power input, use Table 3-A and Figure 3-4.

For DC power return connection, connect to the opposite voltage

(either the -DC or the +DC Pin) and connect the return to ground at the DC power plug on pins 2 and/or 5. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-13 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 3.7.1 DC Power Wiring (Models w/o ODU) Connect the power cable with adequate current rating (minimum of 20 AWG) to the terminals shown on the removed (not plugged into the radio) DC power plug using the screw connections. The recommended minimum current rating of external fuses and cables is 3 Amps. The Tsunami radios consume less than 1 Amp at 48V and less than 2 Amps at 24V. 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 5 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 3-4. 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 3-5. 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).

Connect the ground return connection to pin 1 and use an optional jumper - 2 to 3 for ground reference. See Figure 3-9. If using positive power, connect the positive voltage to pins 1 or 2. Connect the ground return connection to pin 6 and use an optional jumper - 4 to 5 for ground reference. See Figure 3-10. The ground connection is available at pins 3 and 4. 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 and nut (#4x40) is provided on the left front 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. Be sure to use the local electrical code to determine wire size and proper connection to the grounding screw. Use a DVM (digital voltmeter) to verify voltage and polarity on the DC power plug. Do not connect the DC power plug to the front of the IDU until the ODU is connected via coax).

mounted on outdoor permanent structures with a separation distance of at least 1.5 meters from all persons during normal operation. Users and installers must be provided with antenna instructions and transmitter operating conditions, including antenna co-location requirements of 1.1307(b)(3), for satisfying RF exposure compliance. installation The antenna installation consists of permanently mounting the antenna to the mast/pole/tower 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 2.0 feet diameter are not recommended. 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. Be sure to have all the necessary tools available (see section 3.4) before mounting the antenna and ODU. 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 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 radio. See figure 3-11. 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.

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 3.9 before applying DC power to the 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 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 radio ODU. When aligning antennas it may be convenient to allow direct visibility 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 3-13 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 receivers, but an approximate estimate of the potential RSL value may be made using this figure. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-25 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 Use the Factory Test Data Sheet shipped with your terminal to obtain the best estimate 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 not increase up more than 10 dB (except in unusual very long paths which may fade up by 15 dB). 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 antenna's radiated signal. In this case, the antennas should be rotated in a wide arc until the main lobe is located. (Other possible causes of low RSL are path obstructions, loss in connectors, adapters and pigtail jumper cables or different antenna polarization at each end of the link.)

A short length (~6 feet) jumper cable such as RG-214 coax (or pigtail) fitted with two N-

type male connectors can be used to connect the antenna port to the antenna transmission line

(see Section 3.9). The recommended cable 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 LDF4.5-50) is recommended. Coaxial cable 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. Do not use right angle N-type connectors with the 5.8 GHz Tsunami radios: they may present high loss at 5.8 GHz. Do not use a low quality N-type jumper cable with the Tsunami. Some cable types, such as RG-8, may have high loss at 5.8 GHz. Radio w/o Outdoor Unit (ODU) Radio mounting with ODU SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-27 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 3.12 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 length (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 manufacturers 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 building/enclosure. the coax cable before entering the bottom of 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 should 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 stress on either connection. 7/8 inch coax cable or larger is not recommended for use at 5.3 GHz and higher frequencies. Do not use right angle N-type connectors with the 5.3 or 5.8 GHz Tsunami radios: they may present high loss at 5.3 or 5.8 GHz. Do not use a low quality N-type jumper cable with the Tsunami. Some cable types, such as RG-8, may have too high a loss at 5.3 and 5.8 GHz. PAGE 3-28 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 3.13 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 smaller 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 example, 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 manufacturers instructions. Unless special test equipment is available, two operating Tsunami terminals are required to align the antennas. Alternatively, 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 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.

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 front panel RSL test point 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. When aligning antennas it may be convenient to run two wires from the RSL 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 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.

PAGE 3-32 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 3.15 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 tested. This step can eliminate a majority of troubleshooting once the radios are installed. for temporary near-end and A cellular phone or two-way radio system (walkie talkie, CB, mobile radio) can be very useful during installation. These can be used 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. 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. Connect the transmission line to the antenna, and feed it to the Tsunami radio location. 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 IDUs Front Panel ON LED indication is illuminated. This confirms that power has been properly applied. Ensure is properly terminated before applying power to the Tsunami terminal, as in the RF Antenna port connection that SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-33 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 step 3. 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. Place a voltmeter across the GND and PWR front panel test points. See Figure 3-15 for voltage setting information and Table 3-E for typical output power levels for given cable lengths where EIRP limits apply. If necessary, use a small screwdriver at the front panel receptacle to adjust the output power of the local transmitter in accordance with the path analysis calculations. The recessed potentiometer is rotated clockwise to increase transmit output power and counter clockwise to decrease transmit output power. After verifying correct setting of the transmit output power, disconnect the voltmeter. Place the cover cap found in the installation accessory kit over the front panel receptacle. 7. The Tsunami radio requires professional installation. With some Tsunami models, in certain countries, there may be Effective Isotropic Radiated Power (EIRP) the maximum output power that the Tsunami radio can transmit given the transmission line loss and the gain of the antenna.

SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-35 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 8. For precision measurement of transmit output power, it is best to connect an RF power meter to the antenna port. The PWR port voltage may not provide enough precision. This is especially important where EIRP limits apply to the installation. In cases of no EIRP limits, the radio transmitter output power should be left at the factory setting, except for very short paths using very high gain antennas, where excessive power may not be advised. Dont forget that the RF output port should be terminated at all 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 RF 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 (typically 20 dB or more) between the Tsunami radio and the power meter to assure proper operation and safety for the RF power meter. The value of this fixed attenuation can then be added to the value of the RF power meter reading to obtain the actual Tsunami radio transmitter output power. 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 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 3.13. 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 3-14. The Tsunami radio has a unique feature of allowing measurement of the far-end RSL from the near-end radio. This is only possible if the Tsunami radios 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 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.) PAGE 3-36 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001

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

- Weather (inversion layers, ducting and multipath)

- Antenna feed (coaxial/connector) problem 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. 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. 9. 10. 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 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 3.17 for details on these connections. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-37 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 3.16 Output Power Adjustment The Tsunami radio requires professional installation. In certain cases, it is necessary to adjust the output power lower (never higher) from the factory setting, for example:

to meet EIRP (effective isotropic radiated power) limits. 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 directly 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 meters maximum input level. Thruline power meters do not operate at Tsunami RF frequencies. If adjusting the output power to meet an EIRP limit, it will be first necessary to calculate the overall system gains and losses, including feeder losses for the type of transmission line installed and the antenna gain. Also refer to Table 3-E 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) 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. Clockwise rotation increases output power while counter-clockwise rotation decreases output power. In lieu of a calibrated RF power meter, the PWR test port voltage can be used to estimate the output power. Figure 3-15 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 the installation accessory kit over the front panel receptacle. v v v FCC EIRP limitations:

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 3-16 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-

16. 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. If your existing orderwire PAGE 3-40 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 network uses 2 digit addressing, and 0 dBm VF interface, it can be connected to a Tsunami as shown in Figure 3-16. Dialing a V (star key) on the orderwire telephone implements an all call feature which rings all connected radios. Also, if a phone anywhere in the connected network has accidentally been left off-hook, the # (pound key) key can be used to mute all off-hook handsets until they are placed on and off hook again. like a party The orderwire operates telephones provide communication to all other telephones in the connected network. Even if a particular telephone does not ring, it can still be used to talk and listen to any ongoing orderwire activity if the orderwire is in use at other terminal locations. line.

There are two Form C summary alarm relays capable of switching 30 VDC at 1 A. See Table 3-E and Figure 3-17 for Alarm Connections. The summary alarm (Form C relay) is activated by any near-end front panel LED alarm condition, including if the internal test mode is enabled. The out-of-service summary alarm (Form C relay) is activated by any of the following alarm conditions:

SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-43 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 3.14.3 Configuration Port Operation The Config Port is used to retrieve diagnostic information and to configure additional features within the Tsunami radios by means of a computer connection via SERIAL interface. 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-

Connection to the AUX DATA port is an RS-232 serial interface, identical to the config port (see Section 3.17.3). This port does not affect the Ethernet traffic on the Tsunami radio. The following HELP screen will be presented. Type one of the listed commands. In this example, the setIP command was initiated. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-45 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET WIRELESS BRIDGES December 2001 3.17.5 T1 (DSX-1) Interface Connection The Tsunami radio also provides a wayside T1 connection. This connection allows for standard DSX-

1 connect of voice circuits without affecting the Ethernet traffic. A standard RJ-48c connector is provided for this connection. 3.17.6 CEPT-1 (E1) InterfaceConnection The CEPT-1 interface connection provides a balanced (120 ohm) wayside E1 connection. If an unbalanced 75 ohm connection (RJ45) is required, an optional balun will provide this interface. If you can not locate these baluns

(balanced/unbalanced) devices, please consult the factory. Additional external lightning protection devices are recommended for all user connections if the radio is installed in an area prone to lightning. 3.17.7 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 10BaseT 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 10BaseT 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 for details or assistance with NMS connections, if required. factory Note: Multicasting with in-band connection may cause collisions in the data stream.
