INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES December, 1999 3.10 Antenna Installation & Alignment INSTALLER CAUTION: Antennas used for this device must be fix-mounted on permanent outdoor structures to provide 5 feet or more separation from all persons during device operation to comply with FCC RF exposure requirements. Installers should contact manufacturer for applicable 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. PAGE 3-18 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES December, 1999 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 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. provide orderwire telephone will An 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 fine alignment. The phone interconnect cable can be extended to the antenna when desired. for antenna end-to-end 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. PAGE 3-19 SECTION 3: INSTALLATION & ADJUSTMENTS

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 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:

CONVENIENCE to install and operate with no user license Easy 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) SECTION 2: PRODUCT DESCRIPTION PAGE 2-1 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 2.2 Specifications All specifications are subject to change without notice. 2.2.1 Transmitter Frequency Selection NMS selection with installer-removable 7-cavity RF filter assembly Frequency A1 A2 B1 B2 Modulation Dual-Band 5284 MHz 5759 MHz 5316 MHz 5791 MHz OQPSK Single-Band 5750 MHz 5800 MHz N/A N/A Output Power

Prior to installation, it is best to be familiar with the front panel of your particular model. Sections 2.3.2 through 2.3.5 briefly describe the front panel access and indicators. Figure 2-1: Front Panel SECTION 2: PRODUCT DESCRIPTION PAGE 2-9 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 2.3.2 ON GND RSL LOCAL TX PWR

. Test Points / Power Indicator 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. 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. 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, Glenayre 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 and the RSL test point 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. PAGE 2-12 SECTION 2: PRODUCT DESCRIPTION INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 Connections 2.3.5 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 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. SECTION 2: PRODUCT DESCRIPTION PAGE 2-13 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 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. T1 This is a wayside data channel for T1 (DS-1) interface of auxiliary traffic.

AC Power Supply AC Power Cord If ordered as an option, this power supply provides AC to DC conversion for use with AC powered locations. This power cord connects the AC Power Supply, if ordered, to a standard 115V U.S. AC outlet. Rack Mount Brackets Two brackets (along with required mounting screws) are provided which allow 19-

inch rack mounting of the Tsunami radio. Terminal Connector D Connector 9-pin RF Power Adjustment Cover This is a 6-pin mating connector used for DC power supply. Four of these mating connectors are provided. One is used for the VF port, one for the CONFIG port, one for the ALARMS port and one for the AUX DATA port. A small plastic cap is provided which is placed over the RF output power adjustment receptacle once output power has been set by professional installation personnel. Do not adjust the power higher than the factory setting! Before setting the power level lower, note the factory setting or keep the radios configuration sheet attached for future reference. Other accessories are available, such as orderwire handsets, connector adapters and special cables. These can be ordered separately upon request.

This manual Installation accessory kit (see Section 2.5) PAGE 3-2 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 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. Glenayre Western Multiplex recommends a maximum beamwidth of 10 degrees for directional systems. Site Selection Requirements 3.3.1 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 W IRELESS BRIDGES SEPTEMBER 1999 Line-of-Sight and Path Clearance Guidelines 3.3.2 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 W IRELESS BRIDGES SEPTEMBER 1999 RSL Calculation and Link Budget 3.3.3 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 W IRELESS BRIDGES SEPTEMBER 1999 Fade Margin Calculation 3.3.4 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. Availability Calculation 3.3.5 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 W IRELESS BRIDGES SEPTEMBER 1999 Frequency Plan Determination 3.3.6 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 countermeasures in further detail. this manual describes interference SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-7 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 Power Supply Planning 3.3.7 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. Antenna Planning 3.3.8 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 directional antennas should be used with Tsunami radios. These can be flat panel or solid parabolic antennas. PAGE 3-8 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 3.4 Tools Required The following tools may be required for the installation of the 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 arent 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.

This channel plan arrangement allows users to implement Tsunami systems in the proximity of other Tsunami radios (planned or unplanned), hub and repeater applications, and can be used to mitigate interference. The channel plans are illustrated below in Figures 3-1 through 3-2. Section 4.2 and 4.3 describe how to change frequency channel assignments of a Tsunami radio.

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. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-11 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 3.7 Power Connection and Wiring 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 3-3 or 3-4 to connect the DC power cables. For example, for a negative DC power input, use Table 3-A and Figure 3-3. Table 3-A: DC Power Connection for Negative Supply NEGATIVE DC POWER INPUT

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. PAGE 3-12 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 DC Power Wiring 3.7.1 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 3-3. 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). SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-13 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 Figure 3-3: Negative Voltage DC Connection Figure 3-4: Positive Voltage DC Connection Make sure that when connecting the mating plug that it is properly oriented (terminal screws pointing up) and securely fastened. PAGE 3-14 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 AC Power Connection 3.7.2 The optional AC power supply operates from any AC voltage 100V - 250V and 50 Hz or 60 Hz. The AC supply is equipped with a mating connector that plugs directly into the Tsunami radio and an AC cord with a 3-pin AC plug. The AC cord color code is shown in Figure 3-5 in case users wish to replace the AC plug supplied with a different type of plug. Figure 3-5: AC Connection SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-15 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 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 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. PAGE 3-16 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 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 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. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-17 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 3.10 Antenna Installation & Alignment Due to the possibility of exposure to RF radiation above the recommended levels, do not stand within five (5) feet of the antenna during system operation. It is the responsibility of the installer to insure that the antenna is fix-mounted in a place that is not accessible to the public and not pointed in a direction where human exposure may exceed these recommendations. 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. PAGE 3-18 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 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 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. provide orderwire telephone will voice An 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 fine alignment. The phone interconnect cable can be extended to the antenna when desired. for antenna end-to-end 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. Use the Factory Test Data Sheet shipped with your Tsunami 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). SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-19 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 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.)

Additional external lightning protection devices are recommended for the connections if the radio is installed in an area prone to lightning. The 100BaseT connection to the Tsunami is at the data interface on the front of the shelf. Either wire or fiber connections can be used. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-21 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 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 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. 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. PAGE 3-22 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 Ensure that the RF Antenna port connection is properly terminated before applying power to the Tsunami terminal, as in 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. 7. Place a voltmeter across the GND and PWR front panel test points. See Figure 3-7 for voltage setting information and Table 3-C 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. 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. Consult with appropriate government agencies or Glenayre Western Multiplex if there is any question regarding maximum output power allowed.

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. 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 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 3-6 in Section 3-20. 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.)

- Path clearance (line-of-sight, earth curvature, Fresnel zone, diffraction and partial obstruction) SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-25 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999

- 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. 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. 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 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. 10. 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.

(As apply to the in US and Canada) SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-27 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 3.13 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-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) 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 3-7 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 the installation accessory kit over the front panel receptacle. PAGE 3-28 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 3.14 Additional Connections There are additional customer connections which are optional and are not required to make the Tsunami operational but may prove useful. 3.14.1 Orderwire Connection Orderwire is a telephone type wayside service which allows users of the Tsunami radio to establish voice communications from one radio to another, either directly to the companion far-

end, or through a repeater configuration, or several repeater configurations. Telephone connection specifications:

REN (Ringer Equivalency Number) DTMF tones Ringing Voltage

(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 3-18 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 3-8. 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 network uses 2 digit addressing, and 0 dBm VF interface, it can be connected to a Tsunami as shown in Figure 3-8. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-29 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 Dialing a (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. The orderwire operates like a party line. All 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.

There are two Form C summary alarm relays capable of switching 30 VDC at 1 A. See Table 3-E and Figure 3-9 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:

PAGE 3-32 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 3.14.3 Configuration Port Operation The Config Port is used to retrieve diagnostic about the Tsunami radios by means of a computer connection. The config port allows connection of RS-232 devices to poll and receive status of the Tsunami radio. The config port provides front panel alarm and control information and can also provide extended information including some advanced diagnostics and configuration information. Any information that is available on the far-end terminal is also available at the near-end config port

(such as far-end RSL, far-end alarms). Details of this interface are forthcoming in future editions of this manual. At this point in time, it is advised that the NMS port be used with an HTML browser to monitor and configure all radio parameters, when desired. 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 3-10. Figure 3-10: RS-232 Config Port Connections Pins 6 communications to operate properly. through 9 must not be connected for RS-232 SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-33 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 3.14.4 AUX DATA (Digital Service Channel) Connection The AUX DATA port is a separate wayside serial port which can be configured to allow the connection of any user serial data (to 9600 baud) through the radio network. Connection to the AUX DATA port is an RS-232 serial interface, identical to the config port (see Section 3.14.3). This port does not affect the Ethernet traffic on the Tsunami radio. PAGE 3-34 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 3.14.5 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 SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-35 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 3.14.6 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. 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.

Troubleshooting 4.1 Regular Maintenance The Tsunami radios do not require any regular maintenance, however, it is prudent to monitor the radio link at regular intervals to assure that the link conditions are not changing. When visiting a radio site for maintenance, the following items may be checked and their results recorded:

RSL Voltage PWR Voltage Far-end RSL Voltage Alarm conditions Verify radio has adequate ventilation Verify security ID is set the same at each radio through NMS If any alarm conditions exist, they should be recorded, and troubleshooting procedures from this Section of the manual should be followed. SECTION 4: TROUBLESHOOTING PAGE 4-1 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 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. It is not necessary to remove the cover assembly of the Tsunami 1. Remove any cables connected to the antenna connector on the diplexer (filter) and then remove the two screws that mount the filter to the Tsunami 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. 8. Modify the operating frequency as described in the CONFIG menus (Section 4.11) Install the two screws that mount the filter to the rear panel. Single-band versions of this radio can be interchanged from A1 to A2 by changing (but not rotating) the installed filter. After filter 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 A1 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 A1 or B1. The diplexer filters can go on 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. PAGE 4-2 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 4.3 Using a Spare Terminal For dual-band units, a spare of each band may be required. For single-band units, one spare Tsunami terminal will service both channel orientations. See Section 4.2 for changing frequencies of a spare radio. Customers with several radios, or radios in critical operations are encouraged to purchase one or more spare radios of each model in their system. This will allow rapid restoration of radio service in the unlikely event of a radio failure.

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 4.9), 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:

RMA number description of the problem your name and telephone number return shipping address 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 Glenayre 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. Glenayre 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). SECTION 4: TROUBLESHOOTING PAGE 4-5 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 4.6 Front Panel Status LEDs There are several front panel status LEDs on the Tsunami radio. These LEDs indicate conditions where either a hardware failure has occurred or the radio link is not optimum. In many cases, a combination of LEDs may be illuminated. The following sections describe the necessary troubleshooting procedures should any LED(s) indicate a problem during or after installation. Radio Fail RF Link TXD RXD COLL Green = Radio hardware O.K. Red = Hardware failure detected Green = Error-free operation Yellow = Bit errors occurring Red = Excessive bit errors or radio link failure Flashing = Link ID mismatched Green = 100BaseT data transmit present Yellow = 100BaseT port connected (no data present) Off = No 100BaseT connection detected Green = 100BaseT data receive present Yellow = 100BaseT port connected (no data present) Off = No 100BaseT connection detected Yellow = Collisions occurring on 100BaseT (half-duplex mode) FAR END Red = Alarm(s) present on the far-end radio**

** Radio Fail, RF Link (yellow or red), T1 Input (yellow or red) PAGE 4-6 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 RF LINK Alarm 4.6.1 Function:

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

Severe path fading due to atmospheric conditions, usually accompanied by low RSL voltage reading Poor transmission line connections usually accompanied by low RSL voltage reading Antenna problems, misalignment, or path clearance usually accompanied by low RSL voltage reading Improper radio settings (e.g. frequency channel) Received signal level (RSL) is too strong Interference Far-End radio transmitter circuitry is faulty 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 filters are opposite channel plans on each end (e.g. one is A1 and other is A2). Verify that radio frequency settings match each installed filter (in NMS menus). 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 SECTION 4: TROUBLESHOOTING PAGE 4-7 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 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 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 4.9). 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. PAGE 4-8 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 RADIO FAIL Alarm 4.6.2 Function:

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

Internal synthesizers are unlocked 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. 6. If RADIO FAIL alarm does not clear, perform a back-to-back test to verify radio operation, as described in Section 4.9. If RADIO FAIL alarm is still active in a back-to-back test, return the radio to the factory for repair (see Section 4.5). SECTION 4: TROUBLESHOOTING PAGE 4-9 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 FAR END Alarm 4.6.3 Function:

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:

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 through 4.6.4. PAGE 4-10 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 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 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:

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

Path fading due to atmospheric conditions Poor transmission line connections Antenna problems, misalignment or path clearance Received signal level (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 SECTION 4: TROUBLESHOOTING PAGE 4-11 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 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 enable 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 plans (e.g. from A to B) can be very effective. (See Section 4.2). PAGE 4-12 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 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-hand 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 level 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. Interference countermeasures rely to some extent on the measurement of the received interference level and frequency. Prior to turning up a new hop, a spectrum analyzer can be used to monitor 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 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 Use of a Spectrum Analyzer to Evaluate Potential Interference 4.8.1 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. If potential interfering signals are found, then the Tsunami frequency plan can be changed to avoid a receive channel which may contain significant interference (see Section 4.2). For example, interference may be reduced by moving from the A1/A2 plan to the B1/B2 plan or by swapping terminals or RF filters so that A1 becomes A2. Signals outside the receiver frequency range may be ignored:

they will not cause interference. If a spectrum analyzer is not available, the RSL voltage can be used to indicate the background noise and interference level within the receiver RF filter band when the far-end transmitter is turned off. With the far-end radio turned off, if an RSL voltage level below the radios 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 radios threshold

(approximately -80 dBm, depending on radio type). PAGE 4-14 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 4.9 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:

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 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 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 threshold 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. SECTION 4: TROUBLESHOOTING PAGE 4-15 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 Tsunami 5284 Figure 4-1: Back-to-Back Test Configuration The Tsunami radios will be damaged if appropriate attenuation is not supplied between radios. You must provide a minimum of 40 dB and no more than 80 dB attenuation between the two radios. PAGE 4-16 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES SEPTEMBER 1999 4.10 LINK Testing Link testing is the preferred way to evaluate a radio links performance. 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 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 units 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.

1) 2) 3) SNMP Browser graphical user interface TelNet (not implemented at this printing) 4.11.1 SNMP Instructions to be supplied 4.11.2 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 10.0.0.2 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

Product Description 2.1 General Description The Tsunami unlicensed 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 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:

CONVENIENCE to install and operate with no user license Easy 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) SECTION 2: PRODUCT DESCRIPTION PAGE 2-1 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 2.2 Specifications All specifications are subject to change without notice. 2.2.1 Transmitter Frequency Selection Craft port selection with installer-removable 7-cavity RF filter assembly Frequency A1 A2 B1 B2 Modulation Dual-Band 5281.1 MHz 5756.0 MHz 5318.9 MHz 5794.1 MHz OQPSK Output Power (typ.)

Prior to installation, it is best to be familiar with the front panel of your particular model. Sections 2.3.2 through 2.3.5 briefly describe the front panel access and indicators. Figure 2-1: Front Panel, 2.4 GHz PAGE 2-10 SECTION 2: PRODUCT DESCRIPTION INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 2.3.2 ON GND RSL LOCAL TX PWR

. Test Points / Power Indicator 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. This is a test point which relates to the Received Signal Level (RSL). A voltage can be 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. This is a test point which corresponds to the output transmit power of the radio. A voltage can be 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, Glenayre Western Multiplex or other regulatory authorities for limits which may apply. See Section 3.13.1 for details on setting output power. SECTION 2: PRODUCT DESCRIPTION PAGE 2-11 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 2.3.3 TXD RXD COLL NMS Alarm and Status Indicators When lit GREEN, indicates transmitted data is active at the data port. When lit GREEN, indicates received data is active at the data port. This is an alarm. When lit RED, indicates that Ethernet collisions are occurring. These collisions may be normal for a heavily used WAN, but should be remedied as soon as possible as the maximum throughput of the radio link is not being realized. It is normal for the COLL indicator to blink occasionally. This is the network management system alarm. When lit RED, this alarm condition indicates that there is a problem with the connection to the NMS of the Tsunami radio. RF LINK When lit RED, this is an alarm condition indicating that the intended received signal is not being received. This alarm may indicate problems related to the path, connections, or the near-end or far-end radio hardware. T1 Input When lit RED, this is an alarm condition indicating a problem with the wayside T1 connection. RADIO FAIL When lit RED, this is an alarm condition indicating a major failure with the near-end radio hardware. It can also indicate improper connections to the CEPT-1 input port. FAR END When lit RED, this is an alarm condition indicating that there are alarm or status conditions present on the far-end radio. Press and hold the "Display Far End" button on the near-end radios to indicate the alarm conditions for the far-end radio terminal. Monitoring the far-end alarms can be helpful for radio installation and routine maintenance.

end radio. When pressed and held, the alarm and status LEDs and the RSL test point 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 W IRELESS BRIDGES JUNE 1999 Connections 2.3.5 ELECTRONIC ORDERWIRE (EOW) This connection is used to access the 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.

(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 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 a RJ45 100BaseT wire connection or ST 100BaseT fiber connection. PAGE 2-14 SECTION 2: PRODUCT DESCRIPTION INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 AUXILIARY CONNECTIONS There are 6 auxiliary data connections for Tsunami as shown in Figure 2-3. 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 CONFIG AUX DATA 10BaseT NMS T1 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. 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. 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. This is an Ethernet connection for access to the Tsunami NMS (SNMP/HTML). This is a wayside data channel for T1 (DS-1) interface of auxiliary traffic.

This manual Installation accessory kit (see Section 2.5) PAGE 3-2 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 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. Glenayre Western Multiplex recommends a maximum beamwidth of 10 degrees for directional systems. Site Selection Requirements 3.3.1 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 W IRELESS BRIDGES JUNE 1999 Line-of-Sight and Path Clearance Guidelines 3.3.2 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 W IRELESS BRIDGES JUNE 1999 RSL Calculation and Link Budget 3.3.3 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 W IRELESS BRIDGES JUNE 1999 Fade Margin Calculation 3.3.4 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. PAGE 3-6 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 Availability Calculation 3.3.5 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). SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-7 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 Frequency Plan Determination 3.3.6 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 countermeasures in further detail. this manual describes interference PAGE 3-8 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 Power Supply Planning 3.3.7 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. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-9 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 Antenna Planning 3.3.8 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 directional antennas should be used with Tsunami radios. These can be flat panel or solid parabolic antennas. PAGE 3-10 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 3.4 Tools Required The following tools may be required for the installation of the 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 arent 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 Craft Port or NMS access)

- 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.

This channel plan arrangement allows users to implement Tsunami systems in the proximity of other Tsunami radios (planned or unplanned), hub and repeater applications, and can be used to mitigate interference. The channel plans are illustrated below in Figures 3-1 through 3-2. Section 4.2 and 4.3 describe how to change frequency channel assignments of a Tsunami radio.

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. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-13 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 3.7 Power Connection and Wiring 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 3-3 or 3-4 to connect the DC power cables. For example, for a negative DC power input, use Table 3-A and Figure 3-3. Table 3-A: DC Power Connection for Negative Supply NEGATIVE DC POWER INPUT

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. PAGE 3-14 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 DC Power Wiring 3.7.1 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 3-3. 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). SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-15 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 Figure 3-3: Negative Voltage DC Connection Figure 3-4: Positive Voltage DC Connection Make sure that when connecting the mating plug that it is properly oriented (terminal screws pointing up) and securely fastened. PAGE 3-16 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 AC Power Connection 3.7.2 The optional AC power supply operates from any AC voltage 100V - 250V and 50 Hz or 60 Hz. The AC supply is equipped with a mating connector that plugs directly into the Tsunami radio and an AC cord with a 3-pin AC plug. The AC cord color code is shown in Figure 3-5 in case users wish to replace the AC plug supplied with a different type of plug. Diagram TBD Figure 3-5: AC Connection SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-17 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 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 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. PAGE 3-18 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 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 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. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-19 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 3.10 Antenna Installation & Alignment Due to the possibility of exposure to RF radiation above the recommended levels, do not stand within two (2) feet of the antenna for prolonged periods during system operation. It is the responsibility of the installer to insure that the antenna is mounted in a place that is not accessible to the public. The antenna installation consists of mounting the antenna on the 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. If the antenna is to be mounted indoors, "looking" through a window, it is recommended that the antenna be placed approximately 12 inches away from the glass and within 10 degrees of a right angle to the glass. The glass should be lead-free or very low-lead content type and avoid any metallic glass coatings for best results. The antenna must be very rigidly mounted, with adequate room for azimuth and elevation adjustment. 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). PAGE 3-20 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 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 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. provide orderwire telephone will An 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 fine alignment. The phone interconnect cable can be extended to the antenna when desired. for antenna end-to-end 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. Use the Factory Test Data Sheet shipped with your Tsunami 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). SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-21 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 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.) Figure 3-6: Typical RSL Voltage versus Received Signal Level (RSL) PAGE 3-22 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 3.11 Ethernet Interface Connection The 100BaseT interface connection to the Tsunami radio is on the front panel. Additional external lightning protection devices are recommended for the connections if the radio is installed in an area prone to lightning. The 100BaseT connection to the Tsunami is at the data interface on the front of the shelf. Either wire or fiber connections can be used. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-23 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 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 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. 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. PAGE 3-24 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 Ensure that the RF Antenna port connection is properly terminated before applying power to the Tsunami terminal, as in 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. 7. Place a voltmeter across the GND and PWR front panel test points. See Figure 3-7 for voltage setting information and Table 3-C 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. 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. Consult with appropriate government agencies or Glenayre Western Multiplex if there is any question regarding maximum output power allowed. limits which dictate SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-25 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 Figure 3-7: Typical RF Output Power versus PWR Voltage Use the Tsunami Factory Test Data sheet to determine more precisely the voltage corresponding to the RF output power. PAGE 3-26 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 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 can be adjusted to maximum for installation, 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. 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 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 range over the full receiving capability of the radio

(approximately 10 VDC at 0 dBm to 0.0 VDC at threshold). 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.)

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

- Weather (inversion layers, ducting and multipath) SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-27 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999

- 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. 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. 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 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. 10. Now that the link is operational, other services can be connected including Orderwire, Diagnostics, Alarms and Aux Data (Service Channel). Consult Section 3.14 for details on these connections.

(As apply to the in US and Canada) SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-29 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 3.13 Output Power Adjustment The Tsunami radio requires professional installation. In certain cases, it is necessary to adjust the output power from the factory setting, for example:

to meet EIRP (effective isotropic radiated power) limits. to avoid exceeding the maximum far-end RSL of 0 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. 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-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) For the US and Canda, a +30 dBm EIRP limit applies for channels A and B of these Tsunami radios. A +53 dBm EIRP limit applies for channel C. 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 3-7 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 the installation accessory kit over the front panel receptacle. PAGE 3-30 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 3.14 Additional Connections There are additional customer connections which are optional and are not required to make the Tsunami operational but may prove useful. 3.14.1 Orderwire Connection Orderwire is a telephone type wayside service which allows users of the Tsunami radio to establish voice communications from one radio to another, either directly to the companion far-

end, or through a repeater configuration, or several repeater configurations. Telephone connection specifications:

REN (Ringer Equivalency Number) DTMF tones Ringing Voltage

(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 3-18 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 3-8. 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 network uses 2 digit addressing, and 0 dBm VF interface, it can be connected to a Tsunami as shown in Figure 3-8. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-31 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 Dialing a (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. The orderwire operates like a party line. All 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.

The config port allows connection of RS-232 devices to poll and receive status of the Tsunami radio. The config port provides all front panel alarm and control information and can also provide extended information including some advanced diagnostics and configuration information. Any information that is available on the far-end terminal is also available at the near-end config port

(such as far-end RSL, far-end alarms).

Troubleshooting 4.1 Regular Maintenance The Tsunami radios do not require any regular maintenance, however, it is prudent to monitor the radio link at regular intervals to assure that the link conditions are not changing. When visiting a radio site for maintenance, the following items may be checked and their results recorded:

RSL Voltage PWR Voltage Far-end RSL Voltage Alarm conditions Verify radio has adequate ventilation If any alarm conditions exist, they should be recorded, and troubleshooting procedures from this Section of the manual should be followed. SECTION 4: TROUBLESHOOTING PAGE 4-1 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 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. With respect to a given filter, the frequencies are fixed, because tuned RF filters are required for normal operation. Changing of the (pretuned) radio frequencies may be required when installing spares or for special situations, such as interference mitigation. This is accomplished by installing an alternate filter. For any given model of Tsunami, the frequency channel can be changed by swapping the filter. It is not necessary to remove the cover assembly of the Tsunami 1. Remove any cables connected to the antenna connector on the diplexer (filter) and then remove the two screws which mount the filter to the Tsunami 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. 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. 8. Modify the operating frequency as described in the CONFIG menus Install the two screws which mount the filter to the rear panel. PAGE 4-2 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 4.3 Using a Spare Terminal One spare Tsunami terminal of a given model type will service any other radio in that same model type, independent of frequency channel plan. For example, a similar model 5.8 GHz channel A2 can be used as a spare for any A or B channel radio at 5.8 GHz. See Section 4.2 for changing frequencies of a spare radio. Customers with several radios, or radios in critical operations are encouraged to purchase one or more spare radios of each model in their system. This will allow rapid restoration of radio service in the unlikely event of a radio failure.

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 4.9), 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:

RMA number description of the problem your name and telephone number return shipping address 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 Glenayre 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. Glenayre 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). SECTION 4: TROUBLESHOOTING PAGE 4-5 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 4.6 Front Panel Status LEDs There are several front panel status LEDs on the Tsunami radio. These LEDs indicate conditions where either a hardware failure has occurred or the radio link is not optimum. In many cases, a combination of LEDs may be illuminated. The following sections describe the necessary troubleshooting procedures should any LED(s) indicate a problem during or after installation. PAGE 4-6 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 RF LINK Alarm 4.6.1 Function:

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

Severe path fading due to atmospheric conditions, usually accompanied by low RSL voltage reading Poor transmission line connections usually accompanied by low RSL voltage reading Antenna problems, misalignment, or path clearance usually accompanied by low RSL voltage reading Improper radio settings (e.g. frequency channel) Received signal level (RSL) is too strong Interference Far-End radio transmitter circuitry is faulty Near-End radio receiver circuitry is faulty Recommended Actions:

Check the following at each end of the link:

Verify that rear panel filters are opposite channel plans on each end (e.g. one is A1 and other is A2). Verify that rear panel DIP switch settings match each installed filter (see Section 3.12.1). 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 4-7 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 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 higher 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 4.9). 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. PAGE 4-8 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 RADIO FAIL Alarm 4.6.5 Function:

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

Internal synthesizers are unlocked 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. 6. If RADIO FAIL alarm does not clear, perform a back-to-back test to verify radio operation, as described in Section 4.9. If RADIO FAIL alarm is still active in a back-to-back test, return the radio to the factory for repair (see Section 4.5). SECTION 4: TROUBLESHOOTING PAGE 4-9 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 FAR END Alarm 4.6.6 Function:

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:

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 through 4.6.4. PAGE 4-10 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 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 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:

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

Path fading due to atmospheric conditions Poor transmission line connections Antenna problems, misalignment or path clearance Received signal level (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 SECTION 4: TROUBLESHOOTING PAGE 4-11 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 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 5.8 GHz or 7 miles at 2.4 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 enable 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 plans (e.g. from A to B) can be very effective. (See Section 4.2). PAGE 4-12 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 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-hand 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 level into the receiver is 0 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. Interference countermeasures rely to some extent on the measurement of the received interference level and frequency. Prior to turning up a new hop, a spectrum analyzer can be used to monitor 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 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 Use of a Spectrum Analyzer to Evaluate Potential Interference 4.8.1 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. If potential interfering signals are found, then the Tsunami frequency plan can be changed to avoid a receive channel which may contain significant interference (see Section 4.2). For example, interference may be reduced by moving from the A1/A2 plan to the B1/B2 plan or by swapping terminals or RF filters so that A1 becomes A2. Signals outside the receiver frequency range may be ignored:

they will not cause interference. If a spectrum analyzer is not available, the RSL voltage can be used to indicate the background noise and interference level within the receiver RF filter band when the far-end transmitter is turned off. With the far-end radio turned off, if an RSL voltage level above the radios 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 radios threshold

(approximately -87 to -95 dBm, depending on radio type). PAGE 4-14 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 4.9 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:

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 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 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 threshold 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.

You must provide a minimum of 40 dB and no more than 80 dB attenuation between the two radios. PAGE 4-16 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY FAST ETHERNET W IRELESS BRIDGES JUNE 1999 4.10 LINK Testing Link testing is the preferred way to evaluate a radio links performance. 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 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 units 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.
