Product Description 2.1 General Description The Tsunami Spread Spectrum radios provide a new level of control and convenience in a digital communications network. The Tsunami radios provide 10BaseT 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 Ethernet signals over any line-of-sight distance (typically up to 50 miles, depending on terrain and governmental regulations).

. 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, ETSI, 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 2-13 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 2.3.3 TXD RXD COLL BER SYNC MUTE FAN Alarm and Status Indicators When lit GREEN, indicates transmitted data into the wireless link. When lit GREEN, indicates received data from the far end of the wireless link. 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 Bit Error Rate (BER) alarm. When lit RED, this alarm condition indicates that the received signal bit error rate is above the error threshold of 1 x 10-6. This alarm condition typically indicates a path problem or a problem with the far-end radio and usually is not a problem with the near- end radio. 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. When lit RED, this is an alarm condition indicates that one or both of the following:

1) The security address setting for switch 2 on the back of the radio does not match the radio bridge on the other end of the link. 2) There is an excessive number of data errors on the 10BaseT connection that the radio will not transmit so it MUTEs (or BLOCKS) the data from being sent. When lit RED, this is an alarm condition indicating a failure with one or both of the internal cooling fans. The radio is designed to operate within specification when only one fan is operating. The two fans are provided for redundancy only. RADIO FAIL When lit RED, this is an alarm condition indicating a major failure with the near-end radio hardware. 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. PAGE 2-14 SECTION 2: PRODUCT DESCRIPTION INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 2.3.4 Controls ERROR ENABLE Link test transmits either an internal signal and re-transmits this signal back at the far-end radio. The near end then receives the signal. This is very useful for testing because the test signal can be monitored at the near-end and the quality of the entire link can be determined without anyone going to the far-end radio location. When lit RED, this indicates that bit error(s) occurred while in link test mode. This is a push-button switch that executes the link test mode. Link test is initiated by pressing and holding this switch for approximately 3 seconds. Once in link test mode, the LED which is embedded in the switch is illuminated YELLOW to indicate that the test is in progress. The LED on the near-end radio flashes while the far-end is solid. Link test is disabled by pushing and releasing the ENABLE button at either the near-end or far-end radio. Enabling link test will interrupt traffic. This is an out-of-service test. DISPLAY FAR END This push-button provides the capability to determine alarms and status of the far-

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 2-15 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 Connections 2.3.5 ORDERWIRE 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.

Prior to installation, you should familiarize yourself with the rear panel. Figure 2-3: Rear Panel SECTION 2: PRODUCT DESCRIPTION PAGE 2-17 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 RF Connection 2.4.1 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 rear 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. PAGE 2-18 SECTION 2: PRODUCT DESCRIPTION INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 DATA Connections 2.4.2 The connection for the Ethernet interface that carries the signals in and out of the radio is a RJ45 10BaseT connection. Auxiliary Data Connections 2.4.3 There are 5 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 This connector is used for monitoring alarms electrically. The alarm connections are essentially the same as described for the front panel, however instead of LED operation, alarm status is provided electrically by means of TTL and Form C relay connections. The TTL and Form C relays can be connected to other transmission equipment for monitoring alarm status locally or remotely. DIAG-

NOSTICS This is a serial interface port (RS-232 or RS-422, 9600 baud) to the Tsunami radio. This port provides maintenance information about the Tsunami radio(s) to a connected computer or terminal. This port is typically used for maintenance and troubleshooting. AUX DATA This is a serial interface port (RS-232 or RS-422, 9600 baud) which allows the user to connect auxiliary serial data from one point in the radio network to another. This facility can also be used for bridging the DIAGNOSTICS port for remote alarm and status monitoring or for connecting other equipment's serial alarm information. It can alternatively be used for separate data connection for serial devices. SECTION 2: PRODUCT DESCRIPTION PAGE 2-19 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 Switches 2.4.4 There are three sets of 8-segment DIP switches (SW1, SW2 & SW3) and two rotary switches (Address TENS and ONES), as shown in Figure 2-3 on the rear panel of the Tsunami radio. These switches provide user configuration of several radio parameters. A brief explanation for each function follows. Refer to the switch setting detail in Appendix B. SW1 Full or Half Duplex Filtering Enable/

Disable TBOS or Data Choose whether the bridge is to use the half duplex (normal-down position) or the full duplex mode. Half duplex uses the maximum bit rate in one direction while full duplex allows the maximum bit rate to be used in both directions simultaneously effectively doubling the maximum throughput if the LAN on each end of the link can transmit and receive at the same time if the network devices at each end of the bridge can and are set up to utilize the full duplex capability. OFF or down position (normal) allows only frames destined for another LAN to be transmitted over the WAN. ON or up switch setting sends all frames over the WAN. Disable filtering for LAN extender or segmenter applications. Select whether the auxiliary data port is to be used with OpenLYNX (TBOS interface) or by the user as a dedicated data port. OpenLYNX is the default

(down) stetting. Error Unlatch This switch segment selects an optional mode for the ERROR LED to flash for each error occurrence (instead of latching on). This can be useful for short duration link testing when the operator is located at the terminal site and watching for errors. Data Mute Disable Enable Aux Data the bridge radio. The radio may also MUTE This switch, when set in the ON/up position, will disable the automatic MUTE function of links communication if the security addresses of the link are not the same (see switch 2). Refer to section 2.3.3 for a description of the MUTE function and front panel light for further detail. the This switch segment allows the AUX DATA port to be optionally used as a clear service channel for RS-232 or RS-444 ( 9600 baud) user data. The radio normally uses this port for TBOS radio diagnostics. Set the switch to the ON or up position to use this port for your own data use. PAGE 2-20 SECTION 2: PRODUCT DESCRIPTION INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 SW2 Ethernet Bridge Address SW3 Spreading Code Channel Selection These switch segments allow the user to select a unique address for a particular link between two LANs. This feature provides a level of security to prevent another radio in the communication path to pick up the transmitted data unless it is set to the exact same address (1 out of 256 unique addresses). Be sure each point-to-point link is set to the same address. If not, the radio will invoke the MUTE function. This set of switch segments allow the user to select the spreading code for the spread spectrum signal. Both ends of a radio system must be set to the same code. Users may wish to change codes for radios that are nearby other similar radios to aid in interference rejection. (see Section 3.12.3) This set of switch segments programs the radio to match the specific RF channel corresponding to the RF filter set which has been installed. (see Section 3.12.1) Address There are two rotary switches which determine the radio's address (01 to 99). This address is used for Orderwire signaling (dial a particular radio in the network). Refer to Appendix B for Switch Settings SECTION 2: PRODUCT DESCRIPTION PAGE 2-21 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 2.5 Installation Accessories The Tsunami radio is shipped with several accessories commonly required for the radio as described below:

The box contains several related items inside including:

This manual Installation accessory kit (see Section 2.5) PAGE 3-2 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS 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 spread spectrum radios. These can be grid or solid parabolic antennas

(minimum 2 foot - .6 meter). Flat panel antennas are also acceptable if the beam width is kept to a minimum. 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 SPREAD SPECTRUM RADIOS 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 SPREAD SPECTRUM RADIOS 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, 5.8 GHz models of the Tsunami may be installed with any size directional antennas and operated at full power. The 2.4 GHz model may require power reduction where: Pout -

FL1+ G1 is replaced by 30 - [(G1 - 6)/ 3] + FL1 In some countries effective isotropic radiated power (EIRP) limits apply, such as +6 dBW (+36 dBm) in Canada. Output power may need to be reduced, and the above path planning equation changed such that: EIRP (dBm) = Pout + G1 - FL1 SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-5 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS 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, which is shown in Section 2.2, and calculate the fade margin as the difference between the two signal levels. Dispersive fade margin is another factor that many microwave path engineers may use to plan their link budget. For the Tsunami radio, the dispersive fade margin is in excess of 55 dB and therefore is not a determining factor in path planning. This excellent dispersive fade margin performance is important because the spread spectrum RF signal has considerably wide bandwidth. PAGE 3-6 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 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 (2.4 GHz or 5.8 GHz in the case of the 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 SPREAD SPECTRUM RADIOS 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 can be 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 the filter unit, as described in Section 4.2 (thus swapping the frequencies of both ends of the radio link). 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 SPREAD SPECTRUM RADIOS 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. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-9 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 Antenna Planning 3.3.8 Using the path planning tools, 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 spread spectrum radios. These can be grid or solid parabolic antennas (minimum 2 foot - .6 meter). Flat panel antennas are also acceptable if the beam width is kept to a minimum. PAGE 3-10 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS 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)

- 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)

- 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-

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 SPREAD SPECTRUM RADIOS 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 3-7 or 3-8 to connect the DC power cables. For example, for a negative DC power input, use Table 3-A and Figure 3-7. Table 3-A: DC Power Connection for Negative Supply NEGATIVE DC POWER INPUT

Either pin may be used to apply (-DC) DC power input. Similarly, pins 3 and 4 are connected together on the motherboard and may be used to apply (+DC) 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 SPREAD SPECTRUM RADIOS 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 3-7. 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 3-8. 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 SPREAD SPECTRUM RADIOS 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 3-16 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS 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. Figure 3-5: AC Connection SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-17 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS 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 (for 5.8 GHz radios) 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). For 5.8 GHz radios, to minimize feeder losses, the use of 5.8 GHz 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 coax cable can be used with 5.8 GHz radios. 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 SPREAD SPECTRUM RADIOS 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 (2.4 or 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 5.8 GHz and higher frequencies. 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 too high a loss at 5.8 GHz. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-19 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 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. For 2.4 GHz Tsunami radios, a minimum of 4 foot (1.2m) diameter antennas, or larger, are recommended. 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. PAGE 3-20 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 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. 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 3-10 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. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-21 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 Above 0 dBm RSL, the receiver may produce errors: however this level is rarely likely to be exceeded. A link budget calculation should be made to calculate the anticipated RSL as described in Section 3.3.3. During anomalous propagation conditions, the RSL may fade but will not increase up more than 10 dB (except in unusual very long paths which may fade up by 15 dB). Antenna alignment should enable the RSL to be peaked to the level calculated in the link budget. If the RSL is peaked but is approximately 20 dB below the calculated level, then it is likely that the antennas are aligned on a sidelobe of the antenna's radiated signal. In this case, the antennas should be rotated in a wide arc until the main lobe is located. (Other possible causes of low RSL are path obstructions, loss in connectors, adapters and pigtail jumper cables or different antenna polarization at each end of the link.)

Additional external lightning protection devices are recommended for the connections if the radio is installed in an area prone to lightning. The 10BaseT connection to the Tsunami is at the data interface on the rear of the shelf. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-23 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 3.12 DIP Switch Settings A quick reference guide to all DIP switches is provided in Appendix B. DIP switch settings are noted by their position, either up (1), or down (0), not by on/off as may be printed on the DIP switch assembly. 3.12.1 Channel Selection The Tsunami radio offers several frequencies of operation for the 2.4 GHz and the 5.8 GHz models (see Section 3.5).There are DIP switch segments (typical numbers 5 through 8 on SW3) which define the frequency channel plan of the Tsunami radio (refer to Appendix B). The DIP switches must be set to match the filter assembly that is mounted on the radio. For single and double capacity models, positions 5,6 and 7 define the frequency channel plan of the radio (e.g. B), the last DIP switch defines the transmit channel of the radio (e.g. A1 or A2). Radios are shipped from the factory with their DIP switch segments set to match the installed filter. In most cases, no modification of these switches is required.` Also, there are labels on the RF filter illustrating the correct DIP switch settings. One label is right side up and the other is upside down. Set the DIP switch settings for the label that is right side up. If a new filter is installed, or the existing filter is rotated for opposite channel configuration (e.g. A1 to A2), reset the DIP switches to match the right side up label on the filter. Refer to Section 4.2 for more information. The radio channel selection is user adjustable by removing and replacing, or reversing the filter assembly. This allows units of the same radio model to be used as spares for several channels. For example, if a network of Tsunami radios has several radios using all three channel plans at 5.8 GHz, a single spare unit of any channel plan can be used to spare all the radios. If a radio failure were to occur in the network, the filter assembly of the failed unit would be removed and replace the filter assembly in the spare radio. The DIP switch segments on the spare may need to change to match the installed filter and the spare radio could be put into service. The DIP switch setting must match the filter assembly mounted on the radio. Also, both radios of a link must have opposite channel plans (e.g. A1 and A2). Consult Section 4.2 of this manual for more information on changing RF channels. Consult Appendix B for proper frequency channel switch settings. Other NON-standard frequency plans may be offered in the future. In these cases, follow the DIP switch setting on the filter label. PAGE 3-24 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 3.12.2 Spreading Code Selection The spreading code is the pseudo-random chip sequence that is mixed with the data to produce the spread spectrum signal. The spreading code is generated by the Tsunami radio internally. Different codes can be selected using the DIP switches on the Tsunami radio rear panel. The spreading code must be the same for both ends of a radio link. The spreading code has no effect with the Model 31185 (8Mbps) 3-channel Tsunami. Spreading codes are all set in the factory to code 1. Should the code need to be changed, then both ends of the link must be changed. Changing the spreading code is an out-of-service adjustment. There are two DIP switch segments on SW3 located on the rear panel which select the spreading codes. See Figure 3-7 for DIP switch segment settings. Figure 3-7: Spreading Code Selection SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-25 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 3.13 1. System Turn-up to Service 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 DIP switch settings for frequency channel selection match that of the filter that is installed on the rear of the radio. Consult 3.12.1 for further details. The far-end radio must have the same channel plan (e.g. A, B, C) as the near-end radio, and the opposite Tx and Rx frequencies (e.g. A1 and A2 make up a matched pair of radios). Verify that the DIP switch settings for spreading code are the same for both ends of the radio link (see Section 3.12.3). 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 PAGE 3-26 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 accordance with Section 3.7. Verify the polarity and the absolute voltage on all pins. Verify ground connection for power. 7. Connect power to the Tsunami radio. Verify that the Front Panel ON LED indication is illuminated. This confirms that power has been properly applied. Ensure that the RF Antenna port connection is properly terminated before applying power to the Tsunami terminal, as in step 3. 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. 8. Place a voltmeter across the GND and PWR front panel test points. See Figure 3-8 and 3-9 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 In the USA, 5.8 GHz models may be operated at full power. 2.4 GHz models may require a power reduction of 1 dB from +30 dBm input power, as measured at the antenna feed, for every 3 dB that the antenna gain exceeds +6 dB. See Section 3.3.3 and Tables 3-C or 3-D for more details. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-27 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 Figure 3-8: Typical RF Output Power versus PWR Voltage, 2.4 GHz Models Use the Tsunami Factory Test Data sheet to determine more precisely the voltage corresponding to the RF output power. PAGE 3-28 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 Figure 3-9: Typical RF Output Power versus PWR Voltage, 5.8 GHz Models Use the Tsunami Factory Test Data sheet to determine more precisely the voltage corresponding to the RF output power. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-29 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 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. Connect a voltmeter across the GND and RSL front panel test points. This 9. 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) PAGE 3-30 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS 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. 10. 11. Once RSL is verified to be near the predicted value, the radio link is ready for data. You may verify error-free operation by using the link test function, as described in Section 3.13.2. If the link is not error-free, see Section 4.7 for troubleshooting guidelines. Once radio performance is verified and acceptable, with link test mode turned off (press the ENABLE button, the LED will turn off), the Tsunami radios can now be put into service with the intended Ethernet traffic. Connect to the LAN or computer using the RJ45 10BaseT connector. With Ethernet traffic applied in both directions, all front panel LEDs, except for POWER and the data TXD/RXD lights should be off. If any other LEDs are on, consult the trouble shooting sections of this manual. 12. 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.

to meet EIRP (effective isotropic radiated power) limits, such as +6 dBW in Canada. to meet transmitter output limits in the 2.4 GHz band for USA installations. 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 or 3-D 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) In the USA, 2.4 GHz models have an output limit which is determined by:

Tx Power (dBm) = 30 - [(Antenna Gain - 6)/ 3] + Feeder Loss 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. Figures 3-18 & 3-9 illustrate 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 3-34 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 3.13.2 Link Testing When a pair of Tsunami radios are installed and communicating with each other, a link test can be performed to evaluate the bridge performance. The Tsunami uses an internal test signal for link test. To test the link including the far-end radio, press ENABLE and hold for approximately 3 seconds. then release the ENABLE button on the front panel of the near-end radio. The ENABLE LED should now be blinking. If the ENABLE link test button LED is illuminated and not blinking, this means the far-end radio has initiated link test manually. When link test is enabled, the ERROR LED should not illuminate if the path is operating error-

free. If the ERROR LED illuminates, this means that at least one bit error has occurred. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-35 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 3.13.3 Error LED Mode Selection The ERROR LED illuminates if any errors are present in the data stream during link test. The default mode for this LED is latched. That is, when a single error occurs, the LED illuminates and stays lit until link test is turned off. This mode is especially useful for long term

(overnight) testing, or any time that an operator is not watching the radio during testing. There is an optional mode for this LED which is unlatched. This allows the user to view the error rate. In this mode, the LED will flash on each time a single or multiple error occurs. The LED turns off if no further errors occur. This mode can be useful if a BER test set is not available and the user wishes to determine the nature of any error conditions (bursting, dribbling, occasional). In unlatched mode, when any errors occur, the ERROR LED will illuminate for a minimum of one second. If errors continue within this one second interval, the LED will remain on until there are no errors for 1 second. The two modes for this LED are selected by a rear panel DIP switch, as shown in Figure 3-10. Figure 3-10: Error LED Mode Selection In the LED unlatch mode, after 100 errors the ERROR LED will remain lit to indicate excessive errors. PAGE 3-36 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS 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 and Address Selection 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 within 1.5% of nominal freq. 1.0 B Ringing Voltage

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

1. Using a small screwdriver, set the address of both terminals by rotating the address rotary selection switches on the rear panel of the Tsunami radio. The address is a two digit number

(from 01 to 99). Each Tsunami terminal in the network should have a unique address. This address acts like a phone number for other users to call a particular terminal. Each Tsunami terminal should have a unique address. Radio pairs (links) are shipped from the factory with addresses set to 01 or 02. Therefore, if only one pair is being used, address selection may not be necessary. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-37 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 Figure 3-11: RJ-11 Orderwire Telephone Connection 2. 3. 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 3-11 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. Simply pick up the handset of the near-end telephone and dial the two-digit address of the far-end Tsunami terminal. 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). The orderwire address is set by two rotary switches on the rear panel of the Tsunami radio. Use as small screwdriver to select the orderwire address (01 through 99). PAGE 3-38 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 4. 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 25-pin connectors as shown in Figure 3-12. 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 3-18. 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. VF Connector OrderWire Connection Figure 3-12: VF Port Connection SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-39 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 3.14.2 Alarm Connections External alarm outputs are provided at the 25-pin, D-type subminiature ALARM connector. There are two Form C summary alarm relays capable of switching 30 VDC at 1 A. Also, individual alarm logic outputs capable of sourcing and sinking 1mA are provided. These individual alarms interface to a single standard TTL load. When the unit is IN ALARM = 0, the TTL output is 0 V to 0.5 V. When the unit is NO ALARM = 1, the TTL output is +3.5 V to +5.5 V. See Table 3-E and Figure 3-13 for Alarm Connections. The summary alarm (Form C relay) is activated by any near-end front panel LED alarm condition, including if the internal link test mode is enabled. The out-of-service summary alarm (Form C relay) is activated by any of the following alarm conditions:

SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-41 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 3.14.3 Diagnostics Port Operation The Diagnostics Port is used to retrieve diagnostic about the Tsunami radios by means of a computer connection. This port is normally used only by Glenayre Western Multiplex. The diagnostics port allows connection of either EIA standard RS-232 or RS-422 devices to poll and receive status of the Tsunami radio. This serial port provides similar information to that which is normally available to a local operator by means of visual alarms and status (front panel LEDs, ADDRESS, DIP switch settings etc.), including voltage level measurements (such as RSL, PWR) and alarm port (see Section 3.14.2) status. The diagnostics port 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 Diagnostics port (such as far-end RSL, far-end alarms) by means of bridging the AUX DATA port (as described in Section 3.14.4). A DIP switch is used to define the command protocol for this port as shown in Figure 3-

14. The default setting is for user data. The other setting is for factory use only. Figure 3-14: Diagnostic Port Protocol Selection PAGE 3-42 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 3.14.3.1 Diagnostics Port using RS-232 For RS-232 diagnostics connection to the Tsunami radio, connect the serial device (modem, computer, terminal) to the male 9-pin subminiature connector in accordance with Figure 3-15.

Figure 3-16: RS-422 Diagnostic Port Connections Do not connect devices to both the RS-232 and RS-422 connections of the Diagnostics Port. This will cause data conflicts that will result in errors over the interface. PAGE 3-44 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS 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 or RS-422 serial interface, identical to the diagnostics port (see Section 3.14.3). This port does not affect the Ethernet traffic on the Tsunami radio. Figure 3-17: AUX DATA Cable Connection for Repeater/Hub SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-45 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 3.14.5 Fail-over option There is a separate fail-over switch available as an option (please consult the factory for a data sheet, pricing and availability). This protection switch option will switch from one radio to another radio set up similarly at a radio site with each radio being monitored in order to provide an even higher reliability for the radio link. For more information, request the protection switch data sheet or visit the web site.

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 SPREAD SPECTRUM RADIOS 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 the setting of corresponding DIP Switches. (See Section 3.12.1 for more details.) 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 or reorienting the existing filter. For any given model of Tsunami, the frequency channel can be changed by swapping and /or reorienting 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 or orient the existing filter such that the frequency channel label on the filter (showing the DIP switch positions) is right-side-up corresponding 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. Refer to the rear panel filter label or Section 3.12.1 for DIP Switch settings to correspond to Install the two screws which mount the filter to the rear panel. the new filter and reattach the antenna cable. As an example, the filter assemblies of an A1 and A2 terminal are identical. They are simply installed differently. An A1 terminal can be changed into an A2 by removing the filter and rotating it 180 degrees and reinstalling the filter. The DIP switch positions need to match the filter orientation, per the appropriate filter label. PAGE 4-2 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 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, B or C 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. SECTION 4: TROUBLESHOOTING PAGE 4-3 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 4.4 Technical Support Glenayre Western Multiplex provides 24-hour telephone technical support for installed Tsunami radios. Customers are encouraged to troubleshoot the radio and link in accordance with the latter part of this section in this manual before contacting Glenayre Western Multiplex. Glenayre Western Multiplex also has a limited supply of Tsunami radios that can be loaned to out-of-service customers for installation while units are being repaired. Loaner supply is limited, and is only used for critical applications on a first-come, first-served basis. Customer service #:

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 SPREAD SPECTRUM RADIOS 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. PAGE 4-6 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 BER (Bit Error Rate) Alarm 4.6.1 Function:

This LED indicates that the traffic being received from the far-end radio is exceeding the bit error rate threshold of the radio (approximately 1 x 10-6). This indicates that radio traffic currently has errors on it which may exceed acceptable levels. This LED will stay ON as long as the BER threshold is being exceeded. In some cases, it will turn ON and OFF, in which case there are bursts of errors causing intermittent degradation to the received data. In all cases, the LED will be on for at least 1 second for any group of errors which exceed the threshold, whether they are a burst of errors or a long string of errors. If the RX SYNC alarm is ON, the near-end or far-end radio in addition to the BER alarm (on the same radio); the RX SYNC alarm should be the first priority for troubleshooting. Possible Causes:

Path fading due to atmospheric conditions (usually accompanied by Far-End BER alarm) and low RSL voltage reading Poor transmission line connections (usually accompanied by Far-End BER alarm) and low RSL voltage reading Antenna problems, misalignment or path clearance (usually accompanied by Far-End BER alarm) and low RSL voltage reading Interference Received signal level (RSL) is too strong Far-end radio transmitter circuitry is faulty or Tx Power adjusted incorrectly (too low) Near-end radio receiver circuitry is faulty SECTION 4: TROUBLESHOOTING PAGE 4-7 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 Recommended Actions:

An internal loopback test should be performed to verify that errors are occurring over the link:

Verify that the near-end radio is set for internal Link Test mode and Latched Error LED

(both default settings of rear panel DIP switch positions, as described in Sections 3.12.2 and 3.13.3). Press and hold (for approximately 3 seconds, then release) the Link Test Enable switch on the front panel of one radio (this will take radios out of service). Let this test run for a few minutes. If the ERROR LED illuminates, this is verification that errors are on the link and troubleshooting should continue. Press the Link Test Enable switch to deactivate loopback mode. Next 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 (2.4 or 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. PAGE 4-8 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 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 frequencies on both terminals so that they are the opposite from their original settings (e.g. change A1 into A2 and A2 into A1). Make sure that you change the DIP switch settings to correspond to the channel change. After both ends are changed, 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 and set rear panel DIP switches to the desired settings for the installation. SECTION 4: TROUBLESHOOTING PAGE 4-9 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 4.6.2 MUTE Alarm Function:

This LED indicates an alarm condition for one or both of the following:

1) The security address setting for switch 2 on the back of the radio does not match the radio bridge on the other end of the link. 2) There is an excessive number of data errors on the 10BaseT connection that the radio will not transmit so it MUTEs the data from being sent. Possible Causes:

Intermittent path fading due to atmospheric conditions (usually accompanied by Far-

End RX SYNC or BER alarm) and low RSL voltage reading Also refer to 4.6.3 for other radio path problems. Improper radio switch settings (security address) Recommended Actions:

Verify that both radios in the link have the same security code settings. Correct the 10BaseT connection and/or the corrupt data traffic over the LAN. PAGE 4-10 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 4.6.3 RX SYNC (Receiver Synchronization) Alarm 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 Far-End RX SYNC or BER alarm) and low RSL voltage reading Poor transmission line connections (usually accompanied by Far-End RX SYNC or BER alarm) and low RSL voltage reading Antenna problems, misalignment, or path clearance (usually accompanied by Far-End RX SYNC or BER alarm) and low RSL voltage reading Improper radio settings (frequency channel, spread code) 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 each radio is set to the same spreading code (see Section 3.12.3). Verify that all connections between radios and antennas are secure and all devices between radios and antennas are rated for the radio frequency band (2.4 or 5.8 GHz). If RX SYNC alarm continues, follow recommended actions for a BER alarm as described in Section 4.6.1. SECTION 4: TROUBLESHOOTING PAGE 4-11 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 FAN Alarm 4.6.4 Function:

This alarm activates only when one or both of the internal fans are faulty. Possible Cause:

Faulty fan inside the radio. Recommended Actions:

1. Check environmental conditions of the radio. Assure that the ambient temperature at the radio location is within specification of the radio. If not, apply environmental conditioning to radio location or place radio at alternate location where the environmental specifications are met. 2. Visually inspect radio mounting area and ensure that right and left sides of the radio chassis are unobstructed for airflow. 3. Verify that at least one of the internal fans are operational by temporarily covering some of the ventilation holes on the right side of the radio (as you face the front panel) with a thin piece of paper. Slowly pull the paper outwards away from the ventilation holes to determine if the fan is pulling the paper toward the chassis. This can also be checked on the opposite side of the chassis to verify that the fans are pushing air out of the chassis. 4. 5. If at least one fan is working you may wish to postpone repair, as long as the unit is operating without any other errors (the radio is designed to operate with only one fan) If neither fan is working or if typical operating environment is greater than 30C, it is recommended that the unit be repaired at the soonest opportunity. Return the radio to the factory for repair. See Section 4.5 for details. PAGE 4-12 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 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 4-13 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 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 4-14 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS 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 ERROR LED indications during internal link testing. During internal test mode link testing, if an error is detected, the ERROR LED will illuminate. In default mode, this lamp will stay lit during link testing if a single error is detected. If Link Test has been performed over a period of time and the ERROR LED does not latch on, the radio link is operating completely error-free. The ERROR LED only operates in internal test signal link test mode. It is possible that no alarms appear on the front panel during normal operations, but there are errors present in the data stream. If the BER LED is lit, this indicates rather severe error conditions and it is best to follow the procedures provided in Section 4.6.1. In the case of this type of error, the following information can be helpful to troubleshoot the radio link. Indications:

In Link Test Mode, ERROR LED is illuminated Downstream equipment (Router, Switch, Hub, 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 10BaseT wiring. 2. Even if the BER alarm LED is unlit but errors continue, follow the instructions described in Section 4.6.1 SECTION 4: TROUBLESHOOTING PAGE 4-15 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS 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 5.8 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 4-16 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS 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. Spreading Code Selection There are 4 selectable spreading codes provided for the Tsunami radio (See Section 3.12.3). These codes are selected by DIP switches and provide some discrimination against interference from other Tsunami transmitters. The discrimination is limited to approximately 3 to 6 dB for radios using the same channel plan. This is the difference between the co-channel C/I when using different codes for the wanted and unwanted signals. When combined with a different frequency channel, the code discrimination improves significantly beyond 3 to 6 dB. See Section 3.12.3 for code selection details. 6. 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. 7. Equipment/Antenna Location Occasionally, interference is caused by the radio or the antenna being too close to another similar transmitter. For example, at 2.4 GHz, microwave ovens can exhibit interference if mounted near the radio or antenna. Other high powered transmitters may also cause interference. 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 4-17 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS 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 between 2.4 GHz and 2.5 GHz (for 2.4 GHz radios) or 5.7 GHz and 5.9 GHz (for 5.8 GHz radios) 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 range of 2.4 GHz to 2.5 GHz (for 2.4 GHz radios) and 5.7 GHz to 5.9 GHz (for 5.8 GHz radios) 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 4-18 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS 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. When Link Test is enabled at either end, no errors should be registered by the ERROR indication. 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 4-19 INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 Tsunami Tsunami 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 4-20 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL Tsunami FAMILY SPREAD SPECTRUM RADIOS 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 10BaseT inputs and outputs to both radios.

- Verify all DIP switch 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 10BaseT 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.

Upon shipment from the factory, these switches are set for factory default configuration, which is all switches down (in the zero position), except for SW3 positions 5 through 8, which are set to match the installed rear panel RF filter assembly (which determines the frequency channel for transmit and receive, such as A1, A2, B1, B2, etc.). The tables in this section provide a quick reference for the DIP switch functions and their settings. DIP switch settings are noted by their position, either up (1), or down (0), not by on/off as may be printed on the DIP switch assembly.
