Product Description 2.1 General Description The Lynx DS-3 provides a new level of control and convenience in a digital communications network. LYNX DS-3 is not a spread spectrum radio but it operates in the U-NII bands. Under FCC rules governing the U-NII bands, users are not required to have a license to operate the LYNX DS-3 radios in the United States as long as the radios meet the maximum allowable EIRP limits. The Lynx DS-3 carries up to 28 DS-1 signals between two locations without the expense and delay of installing cable or traditional (licensed) microwave. The DS-3 ports can interface any equipment (such as switches, and multiplexers) that provide a telco standard DS-3 port. Because each owner controls the operation of the link there is no reliance on any outside services. Lynx DS-3 operators are able to (1) operate instant links whenever needed, and (2) to be in control of their own network. The Lynx DS-3 offers two primary benefits:
CONVENIENCE Easy to install and operate with no user license requirements or frequency coordination in the USA, including Puerto Rico, and Canada. (Other countries may require a user license and/or frequency coordination). CAPABILITY Full transparent DS-3 signals over any line-of-sight distance (typically up to 20 miles, depending on terrain and governmental regulations). SECTION 2: PRODUCT DESCRIPTION PAGE 2-1 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 2.1.1 LYNX Evolution: 3 Generations In 1992, Western Multiplex Corporation introduced the original first generation Lynx radios. These radios were the first radios to provide T1 and E1 point-to-point communications in the world. In 1994, Western Multiplex Corporation added a significant feature to the Lynx product line. The second generation Lynx.cp product family provided controlled power, which allowed users to adjust the radio transmitter output power in order to meet EIRP limits. Also, Western Multiplex Corporation introduced the first double-capacity radios, the Lynx 2T6 and Lynx 2E6 in this family series. The third generation Lynx.sc and Lynx.HD now continues this product evolution by adding many additional user features, most notably a service channel. The service channel allows radios to carry additional traffic over the radio link, such as alarms or network management. In addition, orderwire and remote/far-end monitoring features have been added along with some improved performance features, such as forward error correction and extended temperature operation. In addition, the Lynx.sc is available in Fractional Capacities (56 to 512 kbps), and Lynx.HD is available in 4xT1and 4xE1 capacities in the 2.4 and 5.8 GHz ISM bands as well as 8xT1 and 8xE1 capacities in the 5.8 GHz ISM band. Lynx DS-3 radios incorporate all the unique features of the Lynx.sc/Lynx.HD generation, e.g. service channel, orderwire, extended operation temperature, far end monitoring, and network management.

Prior to installation, it is best to be familiar with the front panel of your particular model. Sections 2.3.2 through 2.3.5 briefly describe the front panel access and lights from left to right. that are used for Figure 2-1: Front Panel, Lynx DS-3 (single band), 5.3 or 5.8 GHz Figure 2-2: Front Panel, Lynx DS-3 (dual band), 5.3/5.8 GHz SECTION 2: PRODUCT DESCRIPTION PAGE 2-11 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 2.3.2 Test Points / Power Indicator ON This is an LED indication. When lit GREEN, the Lynx DS-3 is powered. GND RSL LOCAL TX PWR
. The Lynx DS-3 product does 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 Lynx DS-3 requires professional installation. Transmitted output power limits may apply when using this radio. Consult FCC, IC, Western Multiplex or other regulatory authorities for limits which may apply. See Section 3.13.1 for details on setting output power. PAGE 2-12 SECTION 2: PRODUCT DESCRIPTION INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 2.3.3 Alarm and Status Indicators DS3 INPUT DS1 INPUT BER When lit RED, this is an alarm condition indicating that the Lynx DS-3 is not receiving DS-3 input data. This alarm function can be disabled by rear panel DIP switch setting (see Section 2.4.4). Under data loss condition, the local transmitter injects AIS (Alarm Indication Signal). When lit RED, this is an alarm condition indicating that the Lynx DS-3 is not receiving DS1 at the DS1 INTERFACE (wayside input port). This alarm function can be disabled by rear panel DIP switch setting (see Section 2.4.4). Under data loss condition, the local transmitter injects AIS (Alarm Indication Signal). 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. RX SYNC 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 the RX SYNC alarm is active, AIS (Alarm Indication Signal) is injected into the DS-3 and DS-1 line transmit output data ports. AIS OUT FAN RADIO FAIL When lit RED, this is a status condition indicating that the radio receiver is transmitting AIS (Alarm Indication Signal) on the DS-3 and DS-1 line transmit output data port, due to loss of received signal. This typically indicates a path or connection problem or a near-end or far-end radio hardware problem. This alarm function can be disabled by rear panel DIP switch setting (see Section 3.12.7). When flashing rapidly, the security ID switches, SW2-1 through SW2-8, on the two radios are not identically set. Under this condition, DS-3 data is muted but other data ports function normally. 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. When lit RED, this is an alarm condition indicating a major failure with the near-end radio hardware. It can also indicate improper connections to the DS-1 output port, e.g. a short to ground on the DS-1 line. 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. SECTION 2: PRODUCT DESCRIPTION PAGE 2-13 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 2.3.4 Controls ERROR DS3 DS1 Loopback is a test method used which transmits either an internal or external test signal and loops this signal back at the far-end radio (re-transmits the signal back to the near end). The near end then receives the signal. The loopback function is very useful for testing the overall link performance. The test signal can be monitored at the near-end using either a bit error rate (BER) test set, or the internal test features, without requiring presence of a second person at the far-end radio location. Lynx DS-3 provides DS-3 loopback using both external and internal test signal, as well as DS-1 loopback using external test source only. When lit RED, this indicates that a bit error occurred while in loopback mode. If you are not using a BER test set, this LED may be observed to determine if there are any bit errors during loopback, for example during an overnight test. This is a push-button switch that executes the loopback mode for the DS-3 channel. Loopback is initiated by pressing and holding this switch for approximately 3 seconds. Once in loopback mode, the LED which is embedded in the switch is illuminated YELLOW to indicate that Loopback is ON. The LED on the near-end radio flashes while the far-end is solid. Loopback is disabled by pushing and releasing the DS3 button on either the near-end or far-end radio. This is a push-button switch that executes the loopback mode for the wayside DS-1. Loopback is initiated by pressing and holding this switch for approximately 3 seconds. Once in loopback mode, the LED which is embedded in the switch is illuminated YELLOW to indicate that Loopback is ON. The LED on the near-end radio flashes while the far-end is solid. Loopback is disabled by pushing and releasing the DS1 button at either the near-end or far-end radio. Enabling either DS3 or DS1 loopback 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.

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 Lynx DS-3 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 2-4: Rear Panel, 5.8 GHz DS-3 (single band) Figure 2-5: Rear Panel, 5.3/5.8 GHz DS-3 (dual band) PAGE 2-16 SECTION 2: PRODUCT DESCRIPTION INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 2.4.1 RF Connection The RF port of the Lynx DS-3 radio is a 50 Ohm, 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 Lynx DS-3, 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 waveguide transmission line at 5.8 GHz, EW-52 waveguide is recommended. EW-63 will also work, but may exhibit more loss. SECTION 2: PRODUCT DESCRIPTION PAGE 2-17 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 2.4.2 DATA Connections (DSX-3 and DSX-1) The connection for the DS-3 signal is BNC female (75 Ohm, unbalanced) as shown in Figures 2-4 and 2-5. There are two types of connections available for the wayside DS-1 interface: RJ-48(C) and DB-9 female. On any radio, either connector may be used as the DS-1 data interface. Using both RJ-48(C) and DB-9 simultaneously at any radio, will cause data errors. PAGE 2-18 SECTION 2: PRODUCT DESCRIPTION INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 2.4.3 Auxiliary Data Connections There are 4 auxiliary data connections for Lynx DS-3 as shown in Figure 2-4 and Figure 2-5. VF This DB-25 male connector is used to link two Lynx DS-3 radios at a repeater site for Orderwire operation. This would allow orderwire "telephone" calls to and from any point in the Lynx DS-3 network. At a 4-way repeater site, the VF ports must be connected to a 4-way, 4-wire bridge. The Lynx DS-3 orderwire circuit can also be connected to other existing orderwire networks. See Section 3.14.1 for details. ALARM This DB-25 female connector is used for monitoring alarms and status 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. In addition to the Form C and TTL alarms, there are two analog monitor points. DIAG-
NOSTICS This DB-9 male connector is a serial interface port (RS-232 or RS-422, 9600 baud) to the Lynx DS-3 radio. This port provides maintenance information about the Lynx DS-3 radio(s) to a connected computer or terminal. This port is typically used for maintenance and troubleshooting or connection to network management systems. AUX DATA This DB-9 female connector 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 (TBOS network management) or for connecting other equipment's serial alarm information. It can alternatively be used for separate data connection for LANs or other serial devices. SECTION 2: PRODUCT DESCRIPTION PAGE 2-19 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 2.4.4 Switches There are three sets of 8-segment DIP switches (SW1, SW2, and SW3) and two rotary switches
(Address TENS and ONES) on the rear panel of the Lynx DS-3 as shown in Figures 2-4 and 2-5. These switches provide user configuration of several radio parameters. A brief explanation for each function follows. Line Build Out
(DS-1) This set of switch segments allows the user to adjust the wayside DS-1 input signal to accommodate a variety of cable lengths from 0 to 655 feet to a DSX-1 interface.
(see Section 3.12.3) Line Code This set of switch segments allows selection between AMI or B8ZS coding for the wayside DS-1 signal. (see Section 3.12.2) Input Alarm Disable AIS Disable These switch segments allow the user to "turn off" the data loss alarms for the DS-1 and DS-3 input channel. This can be helpful if the data channel is not in use or while performing a maintenance or installation operation to temporarily turn off the alarm indication. Even when the data loss alarm is disabled, the Lynx DS-3 will inject AIS into the transmitted data stream when there is a data loss condition. (see Section 3.12.6) This switch segment allows the user to select whether or not an AIS signal will be automatically injected into the received T1 data stream at BER 1 x 10-3. This can be useful for measuring threshold or when a T1 channel is not in use. The AIS will be injected into the received T1 data stream if the radio loses sync (RX SYNC alarm active), even if the AIS disable function has been selected. (see Section 3.12.7) Diag-
nostics Protocol This switch segment is default set to Telemetry Bit Oriented Serial (TBOS) mode on the diagnostics port. This is a non-proprietary network management protocol which is common to some radio networks. The other selection is for factory use only. (see Section 3.14.3) PAGE 2-20 SECTION 2: PRODUCT DESCRIPTION INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 Enable Aux Data Security Code This switch segment allows the AUX DATA port to be optionally used as a clear service channel for RS-232 or RS-422 ( 9600 baud) user data. The radio normally
"bridges" the AUX DATA port to the DIAGNOSTICS PORT for TBOS radio network management.(see Section 3.14.4 or Appendix B) This set of switch segments allow the user to select the security code for the radio. Both ends of a radio system must be set to the same code. Users can protect against nearby similar radios that might pose potential security. If these switches are not matched on the radios, the DS-3 data is muted and the AIS LED will flash rapidly. The selection of these switches does not improve immunity to interference.
(see Section 3.12.5 or Appendix B) Loopback Mode This switch segment allows the user to select either the internal or an external test DS-3 signal for the DS-3 loopback function. DS-1 data loopback is only external and is not selectable. (see Section 3.12.4 or Appendix B) Error Unlatch Line Build Out
(DS-3) Channel Selection Address 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 loopback testing when the operator is located at the terminal site and watching for errors. (see Section 3.13.3 or Appendix B) This switch segment allows the user to adjust the DS-3 output signal to accommodate cable lengths (from 0 to 450 feet or from 450 to 900 feet) to a DSX-3 interface. (see Section 3.12.3 or Appendix B) 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 or Appendix B) There are two rotary switches which determine the radio's address (01 to 99). This address is used for Orderwire signaling and for the DIAGNOSTICS port TBOS address. (see Section 3.14.1) Refer to Appendix B for Switch Settings SECTION 2: PRODUCT DESCRIPTION PAGE 2-21 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 Installation Accessories 2.5 The Lynx DS-3 radio is shipped with several accessories commonly required for the radio as described below:

Installation & Adjustments 3.1 Shipping Container The equipment is shipped in boxes unless ordered as an integrated system and configured at the factory, in which case the equipment may be racked and shipped in a crate. The equipment is packaged so as to prevent damage in transit. The boxes should be left intact and sheltered until arrival at the installation site. the shipping container shows signs of damage, If the transportation company should be notified immediately. Extra care and inspection of the contents is advised immediately upon receipt. It is recommended that all the packaging materials be retained. In the unlikely event that the equipment must be returned to the factory, use the original packing materials for return shipment. The original packaging materials are also recommended for transporting the equipment from location to location. Inside the primary shipping containers, internal boxes may contain other items. These boxes should also be saved for future use. Also, save the Lynx DS-3 test data sheet that is provided. The test data sheet can be placed where the Lynx DS-3 terminal will be installed for future quick reference. This sheet could also be placed in the front pocket of this manual, and the manual kept at the radio location for future reference. All Lynx DS-3 units are individually tested and the actual measured performance recorded on the Factory Test Data Sheet. You will find this information to be of use during installation, troubleshooting and maintenance. A set of quick installation instructions is also provided which can be useful for easy reference during installation.

This manual Installation accessory kit (see Section 2.5) PAGE 3-2 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.3 Before Installation Task List There are several tasks that should be accomplished prior to installing the Lynx DS-3 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 may be used with Lynx DS-3 radios. The Lynx Product Guide provides a more comprehensive description of these tasks. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-3 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.3.1 Site Selection Requirements The radio site must have:
- access to the appropriate power
- close proximity to the telephone or computer system you wish to interconnect
- line-of-sight to the other radio location with adequate clearance
- location for mounting the antenna PAGE 3-4 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.3.2 Line-of-Sight and Path Clearance Guidelines The Lynx DS-3 radios will not operate properly unless they have line-of-sight between their corresponding antennas. The Lynx DS-3 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). The Lynx DS-3 Product Guide should be consulted for further detail on performing these calculations. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-5 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.3.3 RSL Calculation and Link Budget In USA, effective isotropic radiated power (EIRP) limits apply in the U-NII bands. Output power may need to be reduced for certain short paths. Maximum transmitter output power setting can be determined as follows:
Max Transmitter Power (dBm) = E G + FL where: E = 30 dBm for operation in the 5.25-5.35 GHz U-NII band 48 dBm for operation in the 5.750-5.825 GHz U-NII band G = Antenna Gain FL = Feeder Loss, including connectors 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 D = Distance of path in miles
(Dmiles = Dkilometers x 1.609) 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. PAGE 3-6 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.3.4 Fade Margin Calculation The fade margin is the difference between the actual received signal and the radios threshold. Using the formula provided in Section 3.3.3, the anticipated RSL can be calculated. Compare this RSL to the specified threshold of the Lynx DS-3 radio, which is shown in Section 2.2, and calculate the fade margin as the difference between the two signal levels. Refer to the Lynx Product Guide for additional information on fade margin performance for various operational conditions. Dispersive fade margin is another factor that many microwave path engineers may use to plan their link budget. For the Lynx DS-3, the dispersive fade margin is 38 dB, typical. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-7 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.3.5 Availability Calculation Availability of the microwave path is a measure of the percent of the time that the link will operate without producing an excessive BER due to multipath fading. In the absence of direct interference, availability is affected by the following:
- Path length
- Fade margin
- Frequency (5.3 and/or 5.8 GHz in the case of the Lynx DS-3 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, narrower beam antennas in conjunction with lower loss feeders
(by using high quality transmission line or shortening feed length). to the Lynx DS-3 Product Guide Refer for additional information on percentage availability performance for various operational conditions. PAGE 3-8 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.3.6 Frequency Plan Determination When configuring radios in a hub or repeater configuration, careful engineering of the Lynx DS-3 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), this is available in the dual band (5.3/5.8 GHz) Lynx DS-3. 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 Lynx DS-3 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 Lynx DS-3 radio nearby a transmitter that is the same as, or close to the Lynx DS-3 receive or transmit frequencies. In this case, the Lynx DS-3 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 Lynx DS-3 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 Single band Lynx DS-3 (5.8 GHz) operates using one frequency pair (channel A1, A2). Dual band Lynx DS-3
(5.3/5.8 GHz) operates using two frequency pairs (A1/A2 and B1/B2). SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-9 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.3.7 Power Supply Planning The Lynx DS-3 radio must have access to a supply of appropriate power, either DC or AC (if the AC adapter option has been ordered). The Lynx DS-3 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. 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 Lynx DS-3 radio). Backup power allows the radios and associated equipment to continue operation when primary power is interrupted. PAGE 3-10 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.3.8 Antenna Planning Using the path planning tools and equations presented in the Lynx DS-3 Product Guide, proper antenna size can be determined which will yield the desired path performance. In general, the larger the antenna that is used with the Lynx DS-3 radio, the better the link will perform. Larger antennas have narrower beamwidth and higher gain, which will yield better link performance
(higher fade margin, better availability) and improve immunity to interference (due to the smaller beamwidths). However, larger antennas are more costly to purchase and install than smaller antennas, in some cases requiring special equipment for installation. All of these factors should be taken into consideration when selecting an antenna. Consult the Lynx DS-3 Product Guide for more details on selecting antennas. Recommended Antenna Size Gain / 3 dB Beam Width 2 ft 4 ft 6 ft 8 ft 10 ft 29 dB / 6 35 dB / 3 38 dB / 2 41 dB / 1.5 43 dB / 1.3 In areas where transmitted output power restrictions apply, the use of larger antennas will maintain the benefit of narrow beamwidths and receive gain. However, output power may need to be reduced to meet regulations. (See Section 3.13.1) Prior to installation, the specific antenna location and mounting should be determined. This advanced planning also yields the transmission line requirements. Only directional antennas may be used with Lynx DS-3 radios. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-11 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.4 Tools Required The following tools may be required for the installation of the Lynx DS-3 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 Lynx DS-3 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.

Blank rack-mounting spaces above and below the Lynx DS-3 are recommended, especially if the surrounding equipment dissipates a considerable amount of heat (over 50W). The Lynx DS-3 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 Lynx DS-3 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 Lynx DS-3 may alternatively be placed on a table or shelf attached to a wall. Because of the low weight of the Lynx DS-3, any mounting option other than rack mounting will be less secure. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-15 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.7 Power Connection and Wiring There is no ON/OFF switch on the Lynx DS-3. 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 3-5 or 3-6 to connect the DC power cables. For example, for a negative DC power input, use Table 3-A and Figures 3-4, 3-5 and 3-6. 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 3-16 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.7.1 DC Power Wiring 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 Lynx DS-
3 radios consume less than 1 Amp at 48V and less than 2 Amps at 24V. Each Lynx DS-3 terminal should be externally fused separately with a 5 Amp maximum fuse. 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 3-6. 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 3-7. 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 Lynx DS-3 terminal until a load is connected to the antenna port (either an RF pad, or an RF cable and antenna).

A short length (~6 feet) flexible jumper coaxial cable (or pigtail) that is rated for up to 6 GHz and fitted with two N-type male connectors can be used to connect the antenna port to the antenna transmission line (see Section 3.9). A low loss 50-ohm cable (for example LDF4-50 1/2 inch coax) or EW-52 (using a N-type female to waveguide adapter) is recommended for the antenna transmission line between the top of the rack and the antenna. The return loss presented by the transmission line at the top of the rack should be as high as possible (20 dB, minimum recommended). The length of the antenna transmission line should be kept as short as possible (to minimize losses). To minimize feeder losses, the use of 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 as well. For the Lynx DS-3, 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 Lynx DS-3 radios: they may present high loss at 5.8 GHz. Do not use a low quality N-type jumper cable with the Lynx DS-3. Some cable types, such as RG-8, may have high loss at 5.8 GHz. PAGE 3-20 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 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 Lynx DS-3 (5.3 /5.8 GHz). After installation, the transmission line is terminated with an N-type male connector/adapter attached at the equipment end. For waveguide, this typically requires a CPR-to-N adapter. Prior to operation, the electrical integrity of the transmission line, including all connectors, can be checked with a simple DC check between the center conductor and outer conductor. (This is neither possible, nor required for waveguide). The transmission line should ideally be connected directly to the antenna at one end and to the Lynx DS-3 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 Lynx DS-3 radios: they may present high loss at 5.8 GHz. Do not use a low quality N-type jumper cable with the Lynx DS-3. Some cable types, such as RG-8, may have too high a loss at 5.8 GHz.

Please contact Western Multiplex factory for applicable gain and type restrictions to ensure compliance. 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 4 feet diameter are not recommended for urban areas due to their wider beamwidths, which results in higher interference susceptibility. For Lynx DS-3 radios, a minimum of 2 foot (0.6m) diameter (10 beam width) antennas is 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. 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 Lynx DS-3 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 Lynx DS-3. The RSL voltage reading can still be used to peak antennas even if the radios have not synchronized, however far-end RSL cannot be measured from the near-end terminal until radios are synchronized. To coarse align the antenna, first set it for flat elevation (no up or down tilt) using a spirit level. Then point it at a heading marker obtained using a compass back-bearing from an adjacent location, (ideally, 100 feet or more away from the antenna). If a heading marker cannot be set sufficiently far away (for example when on a city building roof or looking through a window) then a rough azimuth setting can be obtained by sighting along the antenna feed. PAGE 3-22 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 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 Lynx DS-3. 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 Lynx DS-3 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 signal level. Then the far antenna is aligned in the same way, using the RSL voltage of its local Lynx DS-3. Higher negative voltage corresponds to weaker RSL. 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 3-9 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 Lynx DS-3 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 Lynx DS-3 terminal to obtain the best estimate of your RSL. Above -5 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 SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-23 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 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.)

The DS-1 interface connection to the Lynx DS-3 is on the rear panel. The transmit and receive signal pairs are wired at the same 9-pin, D-type subminiature connector (See Figure 3-10 for pin connections). An 8-pin modular jack (RJ-48C) style connector is also available for DS-1 connections (See Figure 3-11 for pin connections). The 9-pin, D-type subminiature connector on the Lynx DS-3 is a female connector. A mating male connector should be wired with twin shielded twisted pair cable. Note that the shield must be wired to pin 2 or pin 4 on the radio end of the cable for grounding and not left floating. Additional external lightning protection devices are recommended for the DS-1 connections if the radio is installed in an area prone to lightning.

PAGE 3-26 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 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 single band Lynx DS-3 offers one channel plan, while the dual band Lynx DS-3 offers two channel plans, i.e. A1/A2 and B1/B2 (see Section 3.5). There are DIP switch segments (numbers 6 through 8 on SW3) which define the frequency channel plan of the Lynx DS-3 radio (refer to Appendix B). The DIP switches must be set to match the filter assembly that is mounted on the radio. For single band model, switch position 8 on SW3 determines the channel. For dual band model, switch positions 6, 7, and 8 on SW3 determine the channel (refer to Appendix B). Radios are shipped from the factory with their DIP switch segments set to match the installed filter. 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 both channel plans in the case of dual band Lynx DS-3. 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. Switch positions 4 and 5 on SW-3 are used for other parameters on the Lynx DS-3. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-27 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.12.2 Line Code Selection The DS-3 line code is B3ZS and is not selectable. The standard factory selection for DS-1 line code is Bipolar with 8 Zero Substitution (B8ZS). Should the Lynx DS-3 be required to be transparent to an Alternate Mark Inversion (AMI) coding format of the DS-1 data stream, the line code selection controlled by DIP Switch segments on the rear panel will need to be changed. If a B8ZS code is fed to the Lynx DS-3 while configured for AMI, bipolar violations will exist and errors will be present in the line transmit output signal (DS-1). If an AMI code is fed to the Lynx DS-3 while configured for B8ZS, bipolar violations will exist, but in this case, no errors will be present in the line transmit output signal (DS-1). To change the line code selection from B8ZS to AMI, DIP switch segments will need to be changed. Switch segment 3 on SW1 selects AMI or B8ZS for Channel 1 input. This is an out-of-
service adjustment. See Figure 3-12. 3 1 0 SW1 (REAR PANEL OF LYNX DS-3) 3 1 0 AMI B8ZS Figure 3-9: Line Code Switch PAGE 3-28 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.12.3 Line Build Out Selection Line build out accommodates different lengths of interconnecting cable for the DS-3 and wayside DS-1 (T1) connection. The standard factory selection for line build out (LBO) is 0-125 feet for DS-
1 and 0-450 feet for DS-3. Interconnecting the Lynx DS-3 with other equipment with a cable length greater than the length allowed by the standard LBO setting will require an LBO change. Changing LBO is an out of service adjustment. To change the LBO strap selection from 0-125 feet to a different length, select the position of the DIP switch segments as shown in Figure 3-13.

DIP switch segment SW3-1 selects external vs internal DS-3 test source. The DS-1 loopback is done using ONLY external test source. See Figure 3-14.

On the front panel and over the alarm and diagnostic interfaces, an alarm condition is normally generated if there is no input DS-3 or or no input DS-1 data signal to the radio. For example the Lynx DS-3 radio may have been installed in a location where wayside DS-1 signal is not in use. In this case, it may be desirable to disable the input alarm to the wayside DS-1 channel so that local and remote alarms are not regularly generated by the (known) lack of this data input. When the network is later expanded to include traffic on the wayside DS-1, this switch can be set to enable the input data alarm condition. See Figure 3-16 for DIP switch segment settings. The factory setting is for all input alarms enabled. When a DATA LOSS alarm condition occurs, the Lynx DS-3 will inject AIS into the incoming DS-3/DS-1 data stream, even if the input alarms have been disabled. 4 5 1 0 SW1 (REAR PANEL OF LYNX DS-3) DS-1 SW1-4 Input Alarm Enabled Input Alarm Disabled 0 1 DS-3 SW1-5 Input Alarm Enabled Input Alarm Disabled 0 1 Figure 3-13: Input Alarm Disable Switch PAGE 3-32 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.12.7 AIS Enable/Disable AIS (Alarm Indication Signal) is the blue code (all 1s) that keeps the digital line interface active under data loss conditions. AIS is required by certain equipment to maintain synchronization (for example, it is required on all leased line circuits). However, it is not required by all equipment (for example, a CSU/DSU will initiate its own blue code to the line under data loss conditions). Under test conditions, when measuring receive threshold, for example, it may be necessary, to disable AIS to facilitate BER measurement. There is a user selectable DIP switch segment on the rear panel of the Lynx DS-3 that includes selection of the AIS function (on/off) at the receiver line output. When the AIS is selected (on), the DS-1 or DS-3 signal will send blue code to the line when the received BER on either signal exceeds 1 x 10-3. This function is similar to a data mute function. When the AIS is disabled (off), no insertion of data will take place unless an RX SYNC alarm condition occurs. The AIS switch operates on DS-1 and DS-3 simultaneously. Refer to Figure 3-17 for DIP switch segment information. The standard factory setting is to have the demodulator AIS alarm selected ON because it prevents a severely errored signal (possibly unsynchronized) from being sent out to the line. It is recommended that AIS be selected ON for normal operation. It is recommended that AIS be selected OFF for measuring BER at threshold. This DIP switch does not affect AIS injection into the transmitted data stream upon a DATA LOSS condition. 6 1 0 SW1 (REAR PANEL OF LYNX DS-3) AIS SW1-6 ON OFF 0 1 Figure 3-14: AIS Switch SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-33 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.13 System Turn-up to Service 1. Prior to installing the system, it may be desirable to perform a back-to-back test of the Lynx DS-3 radio pair. Consult section 4.9 for further details. Back-to-back testing is a simple way to verify that the Lynx DS-3 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 Lynx DS-3 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 Lynx DS-3 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 Lynx DS-3 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) 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 security code selection are the same for both ends of the radio link (see Section 3.12.5). With the DC power source active, but not plugged into the Lynx DS-3 radio, using a voltmeter, confirm that the DC mating connector has the proper power connections in accordance with Section 3.7. Verify the polarity and the absolute voltage on all pins. Verify ground connection for power. PAGE 3-34 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 7. Connect power to the Lynx DS-3 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 Lynx DS-3 terminal, as in step 3. When the Lynx DS-3 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 3-18 and 3-19 for voltage setting information and Table 3-C for typical output power levels for given cable lengths where EIRP limits apply. Consult the Lynx DS-3 Product Guide for Path Planning to establish proper level for this setting. 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 Lynx DS-3 requires professional installation. With some Lynx DS-3 models, in certain countries, there may be Effective Isotropic Radiated Power (EIRP) the maximum output power that the Lynx DS-3 radio can transmit given the transmission line loss and the gain of the antenna. Consult with appropriate government agencies or Western Multiplex if there is any question regarding maximum output power allowed. 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 Table 3-D for more details.

PAGE 3-36 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 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 Lynx DS-3 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 Lynx DS-3 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 Lynx DS-3 radio transmitter output power. 9. Connect a voltmeter across the GND and RSL front panel test points. This voltage reading corresponds to the Received Signal Level (RSL) of the near-end radio. In other words, RSL is the amount of signal the near-end radio is receiving from the far-
end radio. Since the antennas have not been finely aligned, it is not expected at this time that the RSL will indicate very high. However, at this point it can be verified that some communication is taking place between the two Lynx DS-3 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 0 VDC at 0 dBm to -0.8 VDC at threshold). The Lynx DS-3 has a unique feature of allowing measurement of the far-end RSL from the near-end radio. This is only possible if the Lynx DS-3 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 5 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 SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-37 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 obstruction)
- Weather (inversion layers, ducting and multipath)
- Antenna feed (coaxial/connector) problem The Lynx DS-3 requires professional installation. Dont forget that the transmitter output power adjustment on the Lynx DS-
3 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 Lynx DS-3 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 loopback function, as described in Section 3.13.2 or BER testing, as described in Section 4.10. If the link is not error-free, see Section 4.7 for troubleshooting guidelines. Once radio performance is verified and acceptable, with loopback mode turned off (press the ENABLE button, the LED will turn off), the Lynx DS-3 radios can now be put into service with the intended T1 traffic. Connect the T1 signal to the DS-1 Interface 9-pin D connector or the RJ-45c connector. Refer to Section 3.11 for pin configurations of these connections. With T1 traffic applied in both directions, all front panel LEDs, except for POWER and any unused T1 ports, will be off. If LEDs are lit, consult Section 4 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.

In certain cases, it is necessary to adjust the output power from the factory setting, for example:
to meet EIRP (effective isotropic radiated power) limits. to avoid exceeding the maximum far-end RSL of 0 dBm. to coordinate a hub or repeater location. To ensure maximum protection of the radio circuits, always ensure the antenna connector is terminated when power is applied. For precise measurement of transmitter power, a calibrated RF power meter (such as the HP 435B with Power Sensor HP8481) is recommended. This power sensor can be connected directly to the output of the radio without exceeding the power rating. With some power meters, it may be necessary to place a calibrated in-line fixed attenuator between the radio antenna port and the power meter so as to not exceed the power meters maximum input level. Thruline power meters do not operate at Lynx DS-3 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, as shown in the Lynx DS-3 Product Guide. 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:
Max Transmitter Power (dBm) = E G + FL where: E = 30 dBm for operation in the 5.25-5.35 GHz U-NII band 48 dBm for operation in the 5.750-5.825 GHz U-NII band G = Antenna Gain FL = Feeder Loss, including connectors 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. 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. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-39 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.13.2 Loopback/BER Testing When a pair of Lynx DS-3 radios are installed and communicating with each other, a loopback or BER test can be performed to evaluate the link performance. The Lynx DS-3 uses an internal test signal for DS-3 loopback. Alternatively, an external test signal can be injected, as described in Section 3.12.4. Additionally, a DS-1 loopback may be performed using an external DS-1 test source such as a T1 BER test set. Any T1 test pattern may be used to make measurements at one end of the link, provided the test sequence contains adequate 1s density, which is no more than 15 consecutive zeros. A 215-1 or QRSS test may be used. However a 223-1 test will violate the 1s density requirement. 1s density requirements only apply when AMI line coding is used. The Lynx DS-3 factory default setting is for B8ZS line coding (see Section 3.12.2). To loop around the far-end radio, press either the DS-3 or the DS-1 loopback push button (located on the radio front panel) and hold for approximately 3 seconds, then release. The orange LED on the loopback enable push button should now be blinking. If the DS-1 or DS-3 loopback button LED is illuminated and not blinking, this means the far-end radio has initiated loopback
(either manually or through the DIAGNOSTICS port). When loopback is enabled using the internal test signal, 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. The DATA LOSS LED will illuminate if the external test signal mode has been selected (see Section 3.12.4) and there is no external test signal present at any of the DS-1 ports (9 pin, modular, or bantam connector). When using external test mode and an external test signal, the ERROR LED function does not apply. In external test mode the ERROR LED will not illuminate, even when errors are present. PAGE 3-40 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 An external BER test set is required for statistical BER analysis. Disconnect all external DS-1 signals and connect the BER test set to the input and output DS-1 MONITOR bantam jacks. Select external test mode (see Section 3.12.4) and initiate loopback using the ENABLE loopback button. Now the BER test can be initiated. Section 4.10 describes BER testing in more detail. Loopback may be turned off at either end of the link by simply pressing the ENABLE button at either end. If two BER test sets are used to measure the link performance
(one at each end) separately in each direction, frame slips will occur unless the BER test sets are synchronized with one test set as the master and the other as the slave. For multiple capacity radio models, only one loopback channel may be used at any one time. Loopback cannot be performed on more than one channel. SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-41 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 3.13.3 Error LED Mode Selection The ERROR LED illuminates if any errors are present in the data stream during loopback. This LED is only functional when using the internal test signal. The default mode for this LED is latched. That is, when a single error occurs, the LED illuminates and stays lit until loopback 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 loopback 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 3-20. 2 1 0 SW3 (Rear panel of LYNX DS-3) ERROR LED SW3-2 ERROR LED Unlatched ERROR LED Latched 1 0 Figure 3-16: Error LED Mode Selection In the LED unlatch mode, after 100 errors the ERROR LED will remain lit to indicate excessive errors.

end, or through a repeater configuration, or several repeater configurations. Telephone connection specifications:
REN (Ringer Equivalency Number) Ringing Voltage
(Ringing voltage is adequate for modern solid state ringers, NOT for the older mechanical type ringers) 1.0 B 48 VDC, typical This Orderwire service does not affect the normal radio transmission of T1 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 Lynx DS-3. The address is a two digit number
(from 01 to 99). Each Lynx DS-3 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 Lynx DS-3 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. Also, in a connected spur network, it may be desirable to maintain orderwire telephone addresses between 01 and 08 because the address doubles as the NMS/TBOS net address which is limited to the addresses 01 through 08 (see Section 3.14.3.3 for more information). SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-43 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 Figure 3-17: RJ-11 Orderwire Telephone Connection 2. 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 Lynx DS-3 front panel. This connector is wired identically to a standard two-wire telephone jack, see Figure 3-21 for details. 3. With a telephone connected to each Lynx DS-3 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 Lynx DS-3 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 Lynx DS-3 radios connected must have unique address settings
(telephone numbers). The orderwire address is set by two rotary switches on the rear panel of the Lynx DS-3. Use as small screwdriver to select the orderwire address (01 through 99). 4. If the Lynx DS-3 radios are connected in a repeater configuration, Orderwire services can be established to all Lynx DS-3 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 Lynx DS-3 terminals between their rear panel VF 25-pin connectors as shown in Figure 3-22. 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 Lynx DS-3 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 Lynx DS-3 as shown in Figure 3-22. PAGE 3-44 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 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 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. telephones in Figure 3-18: VF Port and VF Connections SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-45 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 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 3-23 for Alarm Connections. The summary alarm (Form C relay) is activated by any near-end front panel LED alarm condition, including if the loopback mode is enabled. The out-of-service summary alarm (Form C relay) is activated by any of the following alarm conditions:

Data Loss is activated when the input signal drops below 0.97 volts for 175 bit intervals and is deactivated as soon as the input signal level rises above 0.97 volts. Radio transmits AIS to the far-end if in alarm. This alarm may be disabled by DIP switch selection (see Section 3.12.6). BER - in alarm when the received signal is degraded to an error rate above radio threshold (approximately 1 x 10-6) AIS OUT - in alarm when the BER exceeds 1 x 10-3 for the received signal, or when there is an RX SYNC alarm condition.

TTL signals are in alarm when there is a TTL zero condition
(0 V to 0.5 V). 3.14.3 Diagnostics Port Operation The Diagnostics Port is used to retrieve diagnostic or network management information about the Lynx DS-3 radios by means of a computer connection. This can be accomplished locally or SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-47 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 remotely. Remote diagnostic port connections require either a modem (not included) connection be made to the serial port, when a local dial-up phone line is available at a radio site, or by means of direct connection through the AUX DATA port (Service Channel). The use of the AUX DATA channel can provide a network management port where serial interface data is available from all Lynx DS-3 radios in a network, provided that they are configured properly for this type of operation. (This section and Section 3.14.4 describe this further). The diagnostics port allows connection of either EIA standard RS-232 or RS-422 devices to poll and receive status of the Lynx DS-3 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-
24. The default setting is for TBOS commands (as described later in this section). The other setting is for factory use only.

TBOS is a poll and response protocol that operates on a RS-422 4-wire interface, one pair for transmit data (requests) to the radio, and one pair for receive data
(responses) from the radio. TBOS is asynchronous, serial, half duplex transmissions of ASCII words which consist of one start bit, 8 data bits, odd parity and two stop bits at 1200 baud. The connected terminal (remote or local) can poll the radio and determine status of the connected Lynx DS-3 radio. The Lynx DS-3 is also able to communicate TBOS commands over the RS-232 connections, instead of the RS-422 connections if desired. TBOS operates with a bit-map structure where each bit that the connected Lynx DS-3 radio sends to the TBOS terminal has a specific meaning with regard to status, alarms or controls. All TBOS network elements require a map for the network management software to interpret their responses to queries from the terminal. Table 3-F provides the TBOS map for the T1 Lynx DS-3 radios. The near-end RSL and Tx power test point voltages are encoded as 8 bit words that can be converted into reference voltages (the same as at the front panel of the radio. The address of the radio (see Section 3.14.1) serves as the display page number for the TBOS data. Since TBOS is limited to eight (8) displays of data, it is required that addresses of 01 through 08 be used for Lynx DS-3 radios in TBOS networks. Any radio with addresses other than 01 through 08 will not report to the TBOS bit-map. In order to view status displays of far-end radios, or other radios in the connected network, the AUX DATA port must be in Bridge (default) mode as described in Section 3.14.4. Alarm points within the TBOS map behave like the radio front and rear panel alarms. If DIP switches have been set to disable alarms, the alarms are disabled within the TBOS map.

In the default configuration, this service channel is bridged to the diagnostics port, providing TBOS network management for far-end radios including radio network management through repeaters and hubs. 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 T1 traffic on the Lynx DS-3 radio. For TBOS network management, or when the AUX DATA port is used as a clear service channel, co-located radios can be wired to one another to provide the information throughout the network. At a repeater or hub location, bridging is accomplished by cable connections between co-located Lynx DS-3 radios, via their AUX DATA ports, as shown in Figure 3-27 and 3-28. Figure 3-29 illustrates the pin-to-pin connections for this configuration. There is a related DIP switch position, as shown in Figure 3-30, that makes the AUX DATA port usable for customer data instead of the TBOS network management information. The factory default setting for this DIP switch is for TBOS network management. For non-TBOS external site management systems can be used with the Lynx DS-3 radios; Figure 3-26 shows a typical application. Here the reporting relies on external devices to communicate over the clear service channel of the Lynx DS-3 radio. Each radio is given a site location (see Section 3.14.1) and information on the radio status and control is fed through the diagnostic port to a remote terminal unit (RTU). These RTUs have the capability of providing for other external inputs at the remote site, for complete network management. Communication from each RTU is fed via the RS-232 port to the AUX DATA connector on the radio, in this configuration no bridging is required. RTUs that do not support TBOS can alternatively connect to the Lynx DS-3 alarm connector for discreet TTL alarms and/or test point voltages. If you are using TBOS network management and want full information on the in a single-hop application), the bridge function must be enabled. The service channel can only be used for TBOS network management or for Aux data, not both. When selected for TBOS, no other data should be connected to the AUX DATA port. far-end radio (even SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-53 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 Figure 3-23: Repeater and Hub TBOS Radio Network Management Figure 3-24: Repeater Application with Site Network Management PAGE 3-54 SECTION 3: INSTALLATION & ADJUSTMENTS INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 Figure 3-25: AUX DATA Cable Connection for Repeater/Hub SW1-8

Troubleshooting 4.1 Regular Maintenance The Lynx DS-3 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 LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 4.2 Changing Frequency Plans The Lynx DS-3 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 Lynx DS-3 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 (pre-tuned) radio frequencies may be required when installing spares or for special situations, such as interference mitigation. This is accomplished by installing an alternate filter or re-orienting the existing filter (diplexer). For any given model of Lynx DS-3, the frequency channel can be changed by swapping and /or re-orienting the filter. It is not necessary to remove the cover assembly of the Lynx DS-3 1. Remove the two screws which mount the filter to the Lynx DS-3 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. 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. 6. Slowly place the wired filter assembly so that it is flush with the rear panel. 7. Install the two screws which mount the filter to the rear panel. 8. Refer to the rear panel filter label or Section 3.12.1 for DIP Switch settings to correspond to the new filter. On the single-band Lynx DS-3, the filter assemblies of A1 and A2 terminal are NOT identical. And there is a circulator in each diplexer, so they can not be interchanged. However in the case of dual-band Lynx DS-3, the A1 can be converted to a B1 or vice versa, by changing the diplexer and setting the DIP switches. The same applies to A2 and B2. DIP switch selections need to match the filter orientation, per the appropriate filter label.

(single band) model must be used. The diplexer on the single band model is unique and contains a circulator at the antenna port, therefore the diplexer can not be rotated to accommodate for both A1 and A2 options. That is, for the single-band, a single-band terminal plus one of each type of diplexer is required to accommodate for both A1 and A2 option radios. For dual band (model 27700-91XX) Lynx DS-3 radios, one spare terminal can be used for either A1/B1 and a different spare terminal can be used for A2/B2. Spares for dual band Lynx DS-3
(5.3/5.8 GHz model) are band dependent, and one must be A1/B1 and the other must be an A2/B2. This will require stocking for two terminals as usable spares. A terminal can be re-
channelized from an A1 to a B1 only, or an A2 to a B2 only, but A1/B1 cannot be re-channelized to an A2/B2, as each split band transceiver cannot invert frequency bands. A minimum of one diplexer type may be kept as a spare, because it is bi-directional and can be inverted 180 degrees to change from A1 usage to A2, or B1 usage to B2 or vice versa. 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.

PAGE 4-4 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 4.5 Repair Policy The Lynx DS-3 terminal includes comprehensive alarm indicators designed to diagnose potential faults. 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 Lynx DS-3 is a complex system not designed for user repair. Do not remove the cover or open any part of the Lynx DS-3 terminal. The complete Lynx DS-3 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 W96-10 for complete repair policy details. This document is included in the front of this manual. to Lynx radios should be packaged in their original packing boxes for shipment whenever possible. Western Multiplex can provide an empty box shipment facilitate proper packaging. Regardless, proper and adequate packaging must be used for shipments to protect the radio(s) from damage. Western Multiplex can not be held responsible for any repairs due to inadequately packed materials. Damage caused by improper packing will likely result in higher repair costs and delays (refer to the Warranty section at the beginning of this manual). SECTION 4: TROUBLESHOOTING PAGE 4-5 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 4.6 Front Panel Status LEDs There are several front panel status LEDs on the Lynx DS-3. 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 LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 4.6.1 DATA LOSS Alarms Function:
These DATA LOSS Alarms indicate that no DS-3 and/or DS-1 is present at the rear panel data interface. The DS3 DATA LOSS alarm relates to the DS3 input (BNC) port, while the DS1 input alarm relates to the DS1 input (RJ-48C or DB-9) ports. The data loss alarms do not indicate a radio hardware failure. The capacity of the radio will determine how many DATA LOSS LEDs there are on the front panel. Sometimes the wayside DS-1 is not used at all, or will be used in the future. In this case, the DS1 alarm will be active because no DS-1 signal will be present. This alarm can be defeated by selecting SW1-4, a rear panel DIP switch, in the upside position, as described in Section 3.12.6. When there is a data loss condition, even if the data loss alarm has been disabled, the Lynx DS-3 injects AIS into the (RF) transmitted DS-1 signal. Possible Causes:
No DS-3 and/or DS-1 connection present at rear panel Improper pin connections of DS-3 and/or DS-1 connector(s) No data on DS-3 and/or DS-1 input connector(s) Recommended Actions:
1. Check to make sure that there is a DS-1 connection present on either of the three DS-1 connectors (9-pin D, 8-pin modular jack or Bantam) for the channel in alarm. On a multiple-capacity radio, if the alarm is on a channel which is unused at this time, the alarm condition can be disabled by a rear panel DIP switch, as described in Section 3.12.6.
(continued) SECTION 4: TROUBLESHOOTING PAGE 4-7 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 2. 3. Verify that the DS-1 line has data active at the radio connection. This can be accomplished using a BER tester or signal analyzer at the bantam jacks on the rear panel of the radio. Also, signal activity can be verified by using an oscilloscope. When monitoring the incoming DS-1 signal using the rear panel bantam jack, the BERT must be bridge terminated. Do not double-terminate the DS-1 interface. Verify that pin connections have been made properly (in accordance to Section 3.11). Make sure that you have connected the DS-1 with respect to DTE or DCE, depending on the DS-1 transmitting device. PAGE 4-8 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 4.6.2 BER (Bit Error Rate) Alarm 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 Incorrect setting of the LINE CODE and/or LBO 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 test mode and Latched Error LED (both default settings of rear panel DIP switch positions, as described in Sections 3.12.4 and 3.13.3). Press and hold (for approximately 3 seconds, then release) the Loopback 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. Also verify for both radios that the Line Build Out DIP SECTION 4: TROUBLESHOOTING PAGE 4-9 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 switches and DS-1 Line Code settings are in accordance with external DS equipment
(see Sections 3.12.2 and 3.12.3). Press the Loopback 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. If only one end has low RSL, this could be caused by low transmit output power from the opposite end radio. Verify that the transmitter output power of the radio opposite to the low RSL receiver has been set in accordance to path calculations, or EIRP restrictions (where applicable). Power adjustment must be performed by professional installation personnel only. The PWR test point can be used and compared with the Factory Test Data Sheet, the front panel recessed potentiometer can be turned clockwise to increase power. If an RF power meter is available, this can be connected to the RF output of the radio for precision measurement. This test will also verify that the radio transmitter is working properly. If one terminal (or both) has high RSL, this could be caused by a very short path or interference. To verify the possible presence of interference, remove DC power to the radio which is opposite to the one that is reading high RSL. Once power is removed, measure RSL on the remaining radio. If RSL voltage is higher than that which is listed for "Threshold" in the Factory Test Data Sheet, then an interfering signal is present. If interference is suspected, the easiest potential remedy is to swap frequency channels on both sides of the link. See Section 4.2 for details. Swap 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 the BER alarm continues, an external BER test should be performed to verify the extent of bit errors on the link. See Sections 4.9 and 4.10 for details on bit error rate testing. A BERT can be connected on one side of the link, the External test mode selected on the near-end radio, loopback enabled and bit errors evaluated. If the BER is above acceptable levels, continue to troubleshoot the link. 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 PAGE 4-10 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 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 4-11 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 4.6.3 RX SYNC (Receiver Synchronization) Alarm Function:
This LED indicates that the demodulator function is not synchronizing with the intended received signal. When the RX SYNC alarm is active, the Lynx DS-3 radio injects AIS onto the received DS-3 and DS-1 (line transmit out), even if AIS has been disabled by rear panel DIP switch setting. 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, security 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 security code (see Section 3.12.5). Verify that all connections between radios and antennas are secure and all devices between radios and antennas are rated for the radio frequency band. If RX SYNC alarm continues, follow recommended actions for a BER alarm as described in Section 4.6.2. PAGE 4-12 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 4.6.4 AIS OUT (Alarm Indication Signal) Function:
This LED informs the user that the near-end receiver is operating at BER 1 x 10-3 or is not receiving data and is therefore injecting AIS to the line transmit out of the DS-3 and DS-1 connectors. If the AIS has been disabled by rear panel DIP switch, AIS will not be injected onto the line transmit output unless there is a loss of sync (RX SYNC alarm). Possible Causes:
Local receiver has lost lock (RX SYNC) Local receiver is operating at BER >1 x 10-3 Recommended Actions:
1. Follow recommended actions for a RX SYNC alarm, as described in Section 4.6.3. SECTION 4: TROUBLESHOOTING PAGE 4-13 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 4.6.5 FAN Alarm 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 4-14 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 4.6.6 RADIO FAIL Alarm Function:
The RADIO FAIL alarm indicates a known problem with the radio hardware. Possible Causes:
Internal synthesizers are unlocked Internal digital circuits have failed DS-1 connection is incorrect Recommended Actions:
1. Disconnect the DS-1 connections from the rear panel. 2. If RADIO FAIL alarm clears, check DS-1 connections for proper pin connections and impedance as described in Section 3.11. Check rear panel LBO DIP switch settings as described in Section 3.12.3. 3. If RADIO FAIL alarm does not clear, remove power from the unit. 4. Check to make sure power supply voltages are within specification. 5. Even if the voltages were within specification, reapply power to the unit. 6. If RADIO FAIL alarm clears, place the radio back into service. 7. 8. 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 4-15 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 4.6.7 FAR END Alarm 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 4.6.6. PAGE 4-16 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 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, external bit error rate testing, or ERROR LED indications during internal loopback testing. During internal test mode loopback testing, if an error is detected, the ERROR LED will illuminate. In default mode, this lamp will stay lit during loopback testing if a single error is detected. If Loopback 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 loopback mode. Use a BERT to detect errors when using an external test signal. See Sections 3.12.4, 3.13.2 and 3.13.3 for more details. 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. However, some errors will not result in the BER alarm (such as bipolar violations, slow "dribbling" errors, improperly terminated DS-3 or DS-1 connections or incorrect settings of LBO or Line Code DIP switches), but will be exhibited on downstream data processing equipment or during a BER test. In other cases, there may be data errors due to atmospheric conditions (fading), interference or other reasons, but not at a high enough error level to be indicated with the BER alarm LED. In the case of these types of errors, the following information can be helpful to troubleshoot the radio link. Indications:
In Loopback Mode, ERROR LED is illuminated During external BER test, test equipment indicates errors Downstream equipment (mux, channel bank, CODEC, router, etc.) indicates errors Possible Causes:
Path fading due to atmospheric conditions Poor transmission line connections Antenna problems, misalignment or path clearance Received signal level (RSL) is too strong Incorrect Line Code setting (DS-1 only) Incorrect Line Build Out (LBO) setting Far-End radio transmitter circuitry is faulty Near-End radio receiver circuitry is faulty Interference SECTION 4: TROUBLESHOOTING PAGE 4-17 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 Recommended Actions:
1. Verify DIP switch settings corresponding to DS-1 Line Code (AMI or B8ZS) on both radios, as described in Section 3.12.2. They must be the same setting for both ends of the radio for each corresponding data channel (data channel 1 or data channel 2). Channel 1 and channel 2 can be different from one another if required by external interface equipment. 2. Verify DIP switch settings corresponding to Line Build Out (LBO) length on both radios, as described in Section 3.12.3. These may be different for each connection but need to match the length of the DS-1 cable connected to each data port. 3. Verify that external equipment is also set to the proper DS-1 Line Code (AMI or B8ZS), matching that of the Lynx DS-3 radio setting. 4. Verify DS-3 and DS-1 wiring in accordance to Section 3.11. 5. Even if the BER alarm LED is unlit but errors continue, follow the instructions described in Section 4.6.2 PAGE 4-18 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 Interference Countermeasures 4.8 The recommended interference countermeasures available to the Lynx DS-3 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 Lynx DS-3 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. 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 Lynx DS-3 offers several distinct non-
overlapping frequency channel plans (see Sections 3.5 and 4.2) and the radio's RF filter is able to reject interference more than 20 MHz away from the receive frequency. Offset frequencies combined with other countermeasures may enable several receive channels to operate at a single hub 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). 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. SECTION 4: TROUBLESHOOTING PAGE 4-19 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 Interference can sometimes be overcome by changing antenna polarization at both ends of the link. 5. Transmit Power The maximum level into the receiver is -5 dBm. Above this level, errors may occur in the receive data stream. Transmit output power should be reduced on very short paths to avoid overload. 6. Equipment/Antenna Location Occasionally, interference is caused by the radio or the antenna being too close to another similar transmitter. For example, other high powered transmitters may 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. PAGE 4-20 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 4.8.1 Use of a Spectrum Analyzer to Evaluate Potential Interference Connecting to the antenna and using "peak hold" on a spectrum analyzer, the spectrum between 5.725 GHz and 5.825 GHz (for single-band radios) or 5.250 GHz and 5.825 GHz (for dual-band radios) can be swept and any signals being received at levels above the radio's specified threshold identified. If potential interfering signals are found, then the Lynx DS-3 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 a from the A1/A2 plan to the B1/B2 plan
(dual-band option only) or by swapping terminals or RF filters so that A1 becomes A2. Signals outside the range of 5.725 GHz and 5.825 GHz (for single-band radios) or 5.250 GHz and 5.825 GHz (for dual-band 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 radio's threshold level is measured, there is potentially interference in this frequency channel. When using a spectrum analyzer for determining the presence of interference, very narrow resolution bandwidth settings must be used to detect signals down to the radio's threshold
(approximately 78 to -82dBm). SECTION 4: TROUBLESHOOTING PAGE 4-21 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 4.9 Back-to-Back Testing Back-to-back testing, as shown in Figure 4-1, is an ideal method of testing the Lynx DS-3 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 Lynx DS-3 radio:
BER tester Variable (60 dB range or more) RF attenuator (rated for the proper frequency, 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, without connecting the BER tester, both Lynx DS-3 radios should have no alarm conditions, except for DATA LOSS. When Loopback 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 Lynx DS-3 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 for the radios themselves, 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 BER and threshold tests can be run in both directions to isolate the radio problem
(if any). More information on BER testing is provided in Section 4.10. An RF power meter can be used to individually test each radio's output power. PAGE 4-22 SECTION 4: TROUBLESHOOTING INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 Figure 4-1: Back-to-Back Test Configuration
(When using a BER tester, initiate loopback on connected Lynx DS-3 and select external test mode as described in Section 3.12.4.) The Lynx DS-3 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. SECTION 4: TROUBLESHOOTING PAGE 4-23 INSTALLATION AND MAINTENANCE MANUAL LYNX DS-3 (45 Mbps) LICENSE-FREE (U-NII, LE-LAN) RADIOS MARCH 2000 4.10 BER (Bit Error Rate) Testing Bit error rate (BER) testing is the preferred way to evaluate a radio link's performance. It can be performed from end-to-end or in loopback mode (which tests both directions of the radio path). Figure 4-1 illustrates a typical BER test configuration for loopback testing (which may include the radio's path instead of in-line attenuators). Figure 4-2 illustrates a typical BER test configuration for end-to-end testing. When performing DS-3 BER testing, make sure of the following:
- Disconnect DS-3 inputs and outputs to both radios.
- Connect BER tester to data in/output connector(s)
- Select external test signal for loopback testing using the DIP switches as defined in Section 3.12.
- Verify all DIP switch settings.
- The BER test pattern chosen must contain adequate 1s density For the DS-3, a 215-1 or QRSS test pattern may be used. The Lynx DS-3 factory design for DS-3 line coding is B3ZS (see Section 3.12.2). If two BER test sets are used to measure the link performance separately in each direction, frame slips will occur unless the BER test sets are synchronized with one test set as the master and the other as the slave. BER 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 BER test sets over a link, the far-end unit slaved to the near-end unit's clock) or in loopback mode, as described in Section 4.9. If BER testing indicates an unacceptable level of errors, follow the instructions in Section 4.6.2. or perform a back-to-back test as described in Section 4.9.

Bellcore TR-TSY-000499 Issue 3, December 1989 1. Pulse Density Assurance and Maintenance At all signal interfaces, digital bit streams must contain sufficient energy for self-extraction of timing by various pieces of transmission equipment. The level of energy is controlled by ensuring that sufficient pulses (or ones) are present in the bit stream. In general, as the bit rate increases, the desired level of pulse density also increases, resulting in unique requirements applied to the different levels in the digital hierarchy. This section describes two approaches to ensure pulse density. The first, which is applied at a number of digital hierarchy levels, involves a unique line code substitution when a low pulse density threshold is detected. This is referred to a bipolar with N Zero Substitution (NZAS). The second approach, defined only at the DS-1 level, involves recording of blocks of the digital bit stream to ensure a continuous level of sufficient ones. Normal line coding is then applied to this recorded signal. This technique is referred to as Zero Byte Time Slot Interchange (ZBTSI).
(a) Bipolar with N Zero Substitution (BNZS) Coding BNZS is used at the DS-1 through DS-3 levels for zero code suppression. The line code is fundamentally bipolar. Binary ones in the source data stream are converted to alternating positive and negative pulses in the line signal, whereas no pulses (spaces) are transmitted for binary zeros. In bipolar coding, the polarity is changed at every occurrence of a one. To provide a substituted word that can be easily and reliably identified, BNZS coding uses intentional bipolar violations (BPVs) as its characteristic. BNZS coding substitutes a known pattern of zeros and ones in BPV for a string of zeros. In the signature pattern, B represents a normal bipolar pulse, V represents a pulse violating the bipolar rule, and 0 represents a zero (no pulse).
(b) Bipolar with 8 Zero Substitution (B8ZS) B8ZS is the recommended long-term network solution to providing clear channel capability in a DS-1 rate signal. In a DS-1 code, any sequence of eight consecutive zeros () is replaced with (VBVB). The polarity of the V (violation) pulses in the fourth and seventh bit positions are the same as the preceding pulses in the bit stream. Thus, if the preceding pulse were positive (+), the B8ZS substitution would be (++), while for a preceding negative pulse (), the substitution would be (++). At the receiver, the decoder recognizes the (VBVB) code and replaces it the original eight zeros. Table C-1 is an illustrative example of B8ZS.

(a) Nominal Rate The DS-1 signal has a nominal line rate of 1.544 Mb/s.
(b) Interface Specifications Table A-2 lists the DS-1 interface specifications. All signals appearing at a DS-1 cross-
connect shall satisfy each of the listed requirements.
(c) Pulse Shape Figure A-1 depicts the shape of an isolated pulse appearing at the DS-1 cross-connect. The shape in Figure A-1 applies to the output pulses of all equipment as it is seen at the DS-1. In this figure, the ordinate shows pulse amplitude normalized to unity at the pulse center. The abscissa is a time scale measure in Unit Intervals (UIs) relative to the pulse center. For DS-1, the UI is 648 ns (the reciprocal of the nominal bit rate).
(d) Pulse Density All terminals that generate a DS-1 signal shall meet the following constraints on the density of ones in the signal as delivered to the DS-1 cross-connect:
No more than 15 consecutive zeros In each and every time window of 8(N+1) digit time slots (where N can equal 1 through 23,) there must be at least N ones present. CASE 1 Input B8ZS Substitution Output CASE 2 Input B8ZS Substitution Output PRECEDING PULSE

DS-1 sinks should be capable of accepting a rate deviation of 130 ppm. Either of the following:
(1) Bipolar* satisfying the pulse density constraints of section A.1.
(2) B8ZS as described in Section A.1. One balanced twisted pair shall be used for each direction of transmission. See Figure A-2 for reference. A test load of 100 ohm with a tolerance of plus or minus 5% shall be used for the evaluation of pulse shape and the electrical parameters specified below. This load requirement applies only to DS-1 appearance of a source terminal, not a sink. See Figure A-2. Refer to Figure A-1. The pulse amplitude shall be between 2.4V and 3.6V measured at the center of the pulse, and may be scaled by a constant factor to fit the template.
(1) The power in a band no wider than 3 kHz centered at 772 kHz shall be between 12.6 and 17.9 dBm.
(2) The power In a band no wider than 3 kHz centered at 1544 kHz shall be at least 29 dB below that at 772 kHz. Power Imbalance There shall be less than 0.5 dB difference between the total power of the positive pulses and the negative pulses.
* Bipolar is also known as Alternate Mark Inversion (AMI). Successive logical ones are coded as pulses of alternately polarity. Zeros are coded zero. Two or more successive pulses of the same polarity are termed bipolar violations.

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 position 8 for the single band and SW3 positions 6 through 8 for the dual band option which are set to match the installed rear panel RF filter assembly. So SW3-6 through SW3-8 determine the frequency channel for transmit and receive. 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.
