The term base radio or BR is used to denote the transceiver and associated modules. As viewed in these instances, one base radio is a standalone configuration. A GTR 8000 Base Radio consists of a transceiver module, power amplifier module, fan module, and power supply. The transceiver module includes the functionality for the exciter, receiver, and station control with an optional transceiver option card. The base radio software, configuration, and network management, as well as inbound/outbound traffic handling, are performed through the transceiver module. On-board serial and Ethernet service ports are on this module for local servicing through CSS. The power amplifier module amplifies the low-level modulated RF signal from the transceiver module and delivers the amplified signal on the path to the transmit antenna. The power supply module supports the transceiver and power amplifier modules. Radio Frequency Distribution System (RFDS) provides the interface between the transceivers and the site antennas and between the power amplifier and the site antennas. 29 MN003286A01-H Chapter 1: GTR 8000 Base Radio Description 1.2 GTR 8000 Base Radio Components Table 1: Base Radio Modules and Function Base Radio Description Power Supply Power Amplifier (PA) Transceiver (XCVR) Transceiver Option Card Operates from either an AC or DC input and provides the DC operating voltage for the base radio. May also provide a separate battery charger to maintain the charge on a 48 VDC nominal system, positive or negative ground. Accepts a low-level modulated RF signal from the trans-

ceiver module and amplifies it for transmission through the site transmit antenna. Also provides a low-level RF feedback signal to the transceiver module to achieve the required transmitter linearity. Also performs functions re-

lated to the fan module. Provides the control, exciter, and receiver functions for the base radio. An optional board that attaches to the control board of the transceiver. Provides an internal 10 MHz frequency refer-

ence. For conventional base radio operation, it also pro-

vides the analog interfaces and WildCard I/Os. The trans-

ceiver option card is available in two categories:

OCXO (Oven Controlled Crystal Oscillator) TCXO (Temperature Compensated Crystal Oscillator) NOTICE: The OCXO board when initially pow-

ered on takes a few minutes to reach its opera-

tional temperature. During the warm-up period, if the base radio is configured to use the OCXO frequency reference, the base radio may report a frequency reference failure. This alarm condi-

tion automatically clears once the OCXO board has warmed up sufficiently to provide a stable reference. Fan Provides intermittent forced air cooling for the power am-

plifier and transceiver modules. 1.3 Supported System Configurations The GTR 8000 Base Radio is available in the following system architectures:

High Performance Data (HPD) Trunked IP Simulcast Subsystems (IV&D) ASTRO 25 Repeater Site Trunked Single-Site Repeater Configuration (IV&D) Centralized Conventional Architectures Distributed Conventional (Subsystem) Architecture 30 MN003286A01-H Chapter 1: GTR 8000 Base Radio Description ASTRO 3.1 Conventional System Analog and/or Digital Conventional, Trunked or Mixed-Mode Systems Trunked 3600 SmartZone Systems 1.3.1 Supported Frequencies for Trunked IV and D and Conventional Architectures The GTR 8000 Base Radio is available in the following frequency bands:

700, 800 MHz (700 MHz analog conventional is not available within the U.S.A. or Canada) UHF R1 (380435 MHz) UHF R2 (435524 MHz) VHF (136174 MHz) NOTICE: RF Distribution Functionality (RFDS) information provided in this documentation pertains to the RFDS equipment supplied by Motorola Solutions. 1.3.2 Supported Frequencies for HPD The GTR 8000 Base Radio is available for 25 kHz operation in the following frequency bands:

700 MHz 800 MHz 1.4 Overview For a GTR 8000 Base Radio in a Trunked IP Simulcast Subsystem The base radio captures inbound signals through external receive (Rx) antennas from the subscriber/

mobile radios and then amplifies, filters, and demodulates the signals into voice packets which are forwarded to a comparator. The comparator processes the received voice packets for a particular call and forwards the best quality voice packets to the zone core, which routes them to the associated base radio at each remote site. At a predetermined time, all base radios transmit the voice packets simultaneously on the same frequency to complete the communication. A maximum of 30 base radios can be installed per remote site. Each base radio has an Ethernet connection to a switch at the site for the Network Management interface. 1.5 Overview For a GTR 8000 Base Radio in an ASTRO 25 Repeater Site The base radios in an ASTRO 25 repeater site are set up in a single trunked site, with one active control channel and a number of voice channels at the site. If packet data services are supported at the site, a number of voice channels can be configured with packet data channel capability. Voice traffic is routed from each of the base radios to the system for distribution to other sites and is repeated by the base radios to support other local subscribers. However, data traffic is routed to the GCP 8000 Site Controller. The site controller routes these packets upstream to the zone core for further processing and routing. 31 MN003286A01-H Chapter 1: GTR 8000 Base Radio Description A maximum of 28 base radios can be installed at the site. Each base radio has either an Ethernet connection to a site LAN switch or an Ethernet connection to both site controllers at the site, depending on the site configuration. See the Repeater Site Infrastructure Feature Guide manual for details. Besides the power supply module supporting the transceiver and power amplifier modules, the power supply can also provide auxiliary power to a connected site controller. An ASTRO 25 repeater site can also support a mix of GTR 8000 Base Radios and standalone 10Base-T Ethernet Epic IV or Epic VI QUANTAR stations, or STR 3000 Base Radios. If a mix of GTR 8000 Base Radios and QUANTAR stations are at an ASTRO 25 repeater site, SNMPv1 and clear SWDL support is used at the site. 1.6 Overview For a GTR 8000 Base Radio in a Trunked Single-Site Repeater Configuration This configuration consists of standalone GTR 8000 Base Radios and standalone GCP 8000 Site Controllers in a single-site repeater configuration, or can be used in a multi-site system to provide a system migration step that enables replacement of PSC 9600 Site Controllers or base radios other than the GTR 8000 Base Radios. The base radios may be colocated with the site controllers, or be separated (non-colocated) from the site controllers. NOTICE: This configuration can only be used in non-voting configurations. Support is provided only for FDMA when the base radios are physically separated from and not colocated with the site controllers. TDMA requires the use of a frequency reference and timing reference that can only be provided through the CP3 links on the site controller, which cannot be extended to non-colocated base radios when the distance exceeds the noted limits. This configuration is supported only on repeater sites. An Ethernet cable is used to extend the site controllers signal to the first non-colocated base radio through the site controllers Net AUX port into the base radios SC-A port. The site controllers Net AUX port must be enabled and configured using the CSS for 100/FULL (speed and duplex). When the distance between the site controllers and the first non-colocated base radio exceeds 328 ft (100 m), an external HP 2620 24-port Ethernet LAN switch must be used to extend the site controllers signal. When there are additional non-colocated base radios and those base radios are more than 328 ft (100 m) from the previous non-colocated base radio, additional Ethernet LAN switches are required to continue to extend the signal of the site controller. See Figure 2: Single-Site Repeater Configuration 1 on page 33. 32 Figure 2: Single-Site Repeater Configuration 1 MN003286A01-H Chapter 1: GTR 8000 Base Radio Description If the distance between the first non-colocated base radio and subsequent non-colocated base radios is less than 328 ft (100 m), a single Ethernet LAN switch can be used to distribute the site controllers call control signaling to those non-colocated base radios. The stated distance limit for a shielded twisted pair Ethernet cable (CAT5) is 328 ft (100 m) before the signal degrades too much to be used. See Figure 3: Single Site Repeater Configuration 2 on page 33. Figure 3: Single Site Repeater Configuration 2 Once the site controller link is extended, the control plane could be open to access from elements other than the base radios. Each Ethernet LAN switch must be manually configured to provide MAC Port lockdown to make sure that only the proper devices can communicate with each other. MAC Port lockdown may also be applied on any unused Expansion Ports on the site controller. See the MAC Port Lockdown manual to lock down the site controller. The switch ports may be enabled or disabled according to specific security guidelines. See Enabling/Disabling Ports on HP Switches Using Local Access in the System LAN Switches manual. 33 MN003286A01-H Chapter 1: GTR 8000 Base Radio Description Each non-colocated base radio is equipped with a transceiver option card, which provides an internal 10 MHz frequency reference. See the Reference Oscillator Alignment Procedures of the base radio Alignment Screens in the Configuration/Service Software (CSS) Online Help for alignment details. The base radios that are colocated with the site controllers do not require the transceiver option card. When the Ethernet LAN switch is used in a configuration that does not include centralized network management, the switch must be programmed manually. See the System LAN Switches manual. 1.6.1 Configuring The Ethernet LAN Switch When and where to use: Use this procedure to configure an HP 2620 LAN switch for a Trunked Single-Site Repeater Configuration. Procedure:

1 Enter the following commands at the prompt: ProCurve Switch 2620-24#

2 ProCurve Switch 2620-24#erase startup-config This command removes any existing switch configuration. 3 ProCurve Switch 2620-24#config This command puts the switch into configuration mode. 4 ProCurve Switch 2620-24(config)#int X Using Port X is an example. 5 ProCurve Switch 2620-24(eth-X)#speed-duplex 100-Full This command sets the interface X to 100MB/Full Duplex. 6 ProCurve Switch 2620-24(eth-X)#write memory This command saves the configuration changes to persistent memory. 1.7 Overview For a GTR 8000 Base Radio in a High Performance Data (HPD) Subsystem The GTR 8000 Base Radio provides the radio frequency (RF) link between the system site controller and the subscriber/mobile radios. The base radio captures inbound signals through external receive

(Rx) antennas from the subscriber/mobile radios and then amplifies, filters, and demodulates the signals into data packets which are forwarded to the site controller. The site controller routes/receives digitized data payload to/from the Radio Network Gateway (RNG) for further processing and routing. The site controller receives digitized data payload and control packets from the RNG and routes them to a specified base radio. The base radio extracts the control instructions from the packets and uses them for internal management such as channel frequency assignment. The base radio maps the digital data packets to discreet voltage levels which are then used to modulate an RF carrier. The modulated RF carrier is amplified and may be combined with other RF channels, filtered and routed to the transmission (Tx) antennas. The first four base radios at the site are defined as home channel capable. Settings for the base radio are made through Unified Network Configurator (UNC) and Configuration/Service Software (CSS). Besides the power supply module supporting the transceiver and power amplifier modules, it can also provide auxiliary power to a connected site controller or receive multicoupler/low noise amplifier (RMC/

LNA). 34 MN003286A01-H Chapter 1: GTR 8000 Base Radio Description The HPD base radio provides a full-duplex RF interface to HPD Mobile Subscriber Units (MSUs). The HPD base radios are available for 25 kHz HPD operation in the 700 MHz or 800 MHz bands. Up to five HPD base radios may be installed at the site. Each base radio has an Ethernet connection to both of the site controller modules at the site. The HPD base radio uses Radio Link Adaptation (RLA) to provide high-speed, reliable, enhanced data performance when communicating traffic with MSUs. RLA uses adaptive modulation techniques, with slower, and more reliable modulation for control signaling and retries, and faster modulation methods when traffic is successfully being delivered between the base radio and MSUs. The HPD base radio is implemented with 2X receiver diversity. This receiver diversity enhances the inbound signals from the MSUs on the channel. Figure 4: GTR 8000 Base Radios in HPD Remote Site The HPD base radio uses Time Division Multiplex (TDM) frames for random access channels, reserved access channels, and broadcast messages. All carriers in the system are synchronized by a Global Positioning System (GPS) so that transmission slots are synchronized across sites. The base radio is able to schedule inbound/outbound traffic for half-duplex MSUs so that outbound traffic intended for the MSU does not conflict with inbound random or reserved access traffic from the MSU. 1.8 Overview for a GTR 8000 Base Radio in Conventional Architectures Throughout this manual, the term conventional addresses either an analog only base radio or an ASTRO 25 Conventional base radio that operates in either digital mode or mixed (analog/digital) mode. Conventional base radios operate within:

An analog only infrastructure 35 MN003286A01-H Chapter 1: GTR 8000 Base Radio Description A Centralized or Distributed Conventional Architecture, or An ASTRO 3.1 Conventional System. Each conventional base radio uses either:

A 2- or 4-wire TRC or 4-wire E&M interface in an analog infrastructure A V.24 interface for digital voice and data traffic to either a Channel Bank, Digital Interface Unit, Conventional Channel Gateway (CCGW), MLC 8000, or link converter, ASTRO-TAC 3000 Comparator, and an optional 4-wire link for analog voice in a mixed mode configuration An IP interface for digital voice and data traffic to a CCGW or GCM 8000 Comparator. NOTICE: For information about conventional functions and topologies the base radio supports, see the Conventional Operations manual. The device can be IP managed while using the 4-

wire/V.24 interface for channel traffic. NOTICE: A base radio can be implemented as a QUANTAR replacement within an ASTRO 3.1 conventional system.

The base radio can be used in the following trunked 3600 SmartZone systems:

Trunked SmartX 6809/MTC 3600 Site Controller Simulcast Subsystem Depending on the system capabilities, each base radio can be configured for analog voice (4-wire interface), digital voice (V.24 interface) or mixed-mode (4-wire and V.24 interfaces). These interfaces connect to either a channel bank or ASTRO-TAC 3000 Comparator. The base radio is available in the following frequency bands:

800 MHz UHF R1 (380435 MHz) UHF R2 (435524 MHz) VHF (136174 MHz) NOTICE: A GTR 8000 Base Radio can be implemented as a QUANTAR replacement within a trunked 3600 SmartZone system. The implementation details can be found in the Quick Guide for Replacing a Trunked 3600 QUANTAR with a GTR 8000 Base Radio manual. 1.10 Power Efficiency Package The GTR 8000 Base Radio is available in a Power Efficiency Package, which provides low standby power consumption (see Table 2: Standby Power Consumption on page 39) functionality for ASTRO 25 Conventional base radios and trunked base radios operating in the UHF-R1 and UHF-R2 frequency bands. The Power Efficiency Package optimizes the power consumption for supported base radios for the use of power generated from alternate energy sources such as solar or wind. 38 MN003286A01-H Chapter 1: GTR 8000 Base Radio Description The Power Efficiency Package hardware includes a modified transceiver, power amplifier, power supply, fan, and optional transceiver option card (internal reference) along with additional software configurations through Configuration/Service Software (CSS). The following conditions must be met to obtain a power consumption of less than or equal to 35 W:

DC source only Speaker turned OFF (if equipped with a transceiver option card) No activation of Aux Out Relays (if equipped with a transceiver option card) No 29 V AUX loads. For example: active draws by a site controller CSS configured for applications not requiring receiver diversity CSS Fan Holdover configured to short (length of time the fan stays ON after transmission) Ambient temperature of 104 F (40 C) or less (single fan operation disabling one of the fans within the fan module. See Replacing the Fan Assembly on page 238 in the Field-Replaceable Unit

(FRU) Procedures chapter for instructions on how to disable the fan.) NOTICE: To validate the 35 W standby power consumption specification, wait for the main fans to turn off after the transmitter dekeys. The turn off delay of the main fans is controlled by the fan holdover configuration in the CSS. Single fan operation requires the Tx Power Out in the CSS to be limited to 50 W. Transceiver, power amplifier, power supply, fan, and TCXO transceiver option card (internal reference) are all power efficiency package versions NOTICE: The TCXO transceiver option card is available only for non-simulcast conventional systems. The OCXO transceiver option card is available for trunked or simulcast systems, but does not guarantee 35 W. Table 2: Standby Power Consumption cast 35 W 35 W Internal Reference Ca-

This chapter explains how the GTR 8000 Base Radio works in the context of your system. 2.1 Functions of the GTR 8000 Base Radio Modules The following lists GTR 8000 Base Radio modules:

Transceiver (XCVR) module (with or without a transceiver option card) Power amplifier module Fan module Power supply module 2.1.1 Function of the Transceiver Module The transceiver module provides the control, exciter, receiver, and optional transceiver option card for the base radio. Figure 5: Transceiver Module (Front View) The transceiver generates the station reference, which typically must be locked on to one of many possible external sources. The external source can be either the site controller TDM clocks or the external reference operating at 5 MHz or 10 MHz. The transceiver SPI bus allows communication with its receiver and exciter circuitry, as well as the power supply module and power amplifier module. Two or three circuit boards in the transceiver are:

Transceiver Control Board Performs the control management, digital signal processing, and transmit and receive data formatting for the base radio. Transceiver RF Board Contains DC power conversion/regulation and performs receiver and exciter functions. 61 MN003286A01-H Chapter 2: GTR 8000 Base Radio Theory of Operation Transceiver Option Card An optional board that attaches to the control board. Provides an internal 10 MHz frequency reference. For conventional operation, it also provides the analog interfaces and WildCard I/Os. The transceiver option card requires an internal frequency reference oscillator alignment at different intervals mandated by its category and frequency band. See Base Radio Service Help > Service Screens > Alignment Screens in the CSS Online Help for the alignment procedures and mandated intervals. The transceiver option card is available in two categories:

OCXO (Oven Controlled Crystal Oscillator) operates at 0.1 ppm and is inclusive to temperature and aging. The OCXO Transceiver Option Card is available in 700/800 MHz, UHF R1/R2, and VHF frequency bands. TCXO (Temperature Compensated Crystal Oscillator) operates at 1.5 ppm, of which 0.5 ppm is allocated to temperature, and 1.0 ppm is allocated to aging. Reference precision with the TCXO is traded for lower power consumption. The TCXO mandates shorter maintenance intervals. The TCXO transceiver option card is available in UHF R1/R2 frequency bands. The TXCO is only available for non-simulcast conventional systems. 2.1.1.1 Transceiver Control Board The main operating software for the base radio is loaded in the XCVRs control section. As the main manager for the base radio, the XCVR control board provides operational control over the other station modules. It handles three types of information flow, in the following ways:

Serves as a gateway between the network and RF functionality, by distributing the RF payload to and from the network. Supports operational and diagnostic functions with digital control data (for example: site information, channel assignments, and identification numbers for call processing). Ensures the flow of other network management configuration information. Figure 6: Transceiver Control Board Information Flow on page 62 shows the information flow through the transceiver control and RF sections for trunked and conventional operation. Figure 6: Transceiver Control Board Information Flow 2.1.1.2 Transceiver RF Board In addition to DC power conversion/regulation, the XCVR RF board provides circuitry for the following exciter and receiver functions. 62 MN003286A01-H Chapter 2: GTR 8000 Base Radio Theory of Operation 2.1.1.2.1 Exciter 2.1.1.2.2 Receiver The exciter on the XCVR RF board provides the transmitter functions for the base radio. The exciter circuitry generates a low-level, modulated RF signal that passes to the power amplifier. It supports various modulation types as well as bandwidths up to 25 kHz, through software programming. The exciter also provides a controlled output power level to the power amplifier. The receiver provides either single receiver input or dual (HPD or TDMA) receiver inputs for dual diversity. The receiver also provides enhanced diagnostic capabilities using an on board noise source generator. It includes a wide tuning range (electronic varactor-tuned) preselector. The preselector is electronically tuned to the desired receive frequency anywhere between 792825 MHz, UHF R1 380 435 MHz, UHF R2 435524 MHz, or VHF 136174 MHz. 2.1.1.3 Transceiver External Interfaces The transceiver external interfaces include seven external ports, a switch, and LEDs. If a transceiver option card is part of the transceiver, there are four additional external ports. See GTR 8000 Base Radio Front Connections on page 111 for the port connections. See GTR 8000 Base Radio LEDs on page 265 for information on the LEDs. 2.1.1.3.1 Transceiver Switch The multifunction RESET switch on the front of the transceiver module is accessible through the drop-

down door to the left of the fans. The RESET switch has two functions:

Figure 7: Transceiver RESET Switch (viewable through the drop-down door) Table 29: Transceiver Front RESET Switch Functions User Action Result Press switch for less than 1 second Toggles between Tx Inhibit and Tx Enable (LED 3 blinks amber) Press switch for more than 3 seconds, then re-

Pressing the intercom button toggles the intercom function between the ON and OFF states. Figure 8: Transceiver Option Card Intercom Button (behind the fan module) 2.1.1.3.3 Transceiver Ports (Rear) The transceiver interconnects to the backplane using a 120-pin HVDML digital connector and 8-pack RF connector, as shown in the figure. These connections handle multiple signals including power supply communications, power amplifier communications, fan interface, and peripheral interface. The digital connection receive alarm data and the site controller Time Division Multiplexer (TDM) signals are used to pass reference and control data to the base radio. Figure 9: Transceiver Module (Backplane Connections) Single Receiver Input Dual Receiver Input An RJ-45 Ethernet port on the backplane is cabled to a site LAN switch for this channel. The backplane also provides an RF connection to the transceiver for receive (Rx) path A. RJ-45 Ethernet ports on the backplane are cabled to corresponding ports on the site controller backplanes (HPD). The backplane also provides RF connections to the transceiver for receive (Rx) paths A and B (HPD and TDMA). 2.1.2 Function of the Power Amplifier Module The power amplifier (PA) is a forced convection-cooled RF power amplifier. It accepts a low-level modulated RF signal from the transceiver module, and amplifies it for transmission through the site transmit antenna. Also, to complete the Cartesian correction loop (linearization method), it provides a low-level RF feedback signal to the transceiver module to achieve the required transmitter linearity. Transmit power output can be set using Configuration/Service Software (CSS). See Configuring Tx Power Values and Battery Type on page 154. 64 MN003286A01-H Chapter 2: GTR 8000 Base Radio Theory of Operation The power amplifier also performs functions related to the fan module, including reporting of the fan module status and supplying power to the fan power bus. Figure 10: Power Amplifier Module The power amplifier is comprised of six internal modules:

Core Board Converter Board Driver Amplifier Board Final Amplifier Board Distribution Board Output Circuitry 2.1.2.1 Power Amplifier Input/Output Connections There are three electrical connection assemblies on the power amplifier:

RF output (front QN "quick-N" connector) on the front of the power amplifier module NOTICE: This is cabled to the N-type female bulkhead connection at the rear of the base radio housing. DC power supply/control signal (backplane connection) RF input/feedback (backplane connection). 65 MN003286A01-H Chapter 2: GTR 8000 Base Radio Theory of Operation Figure 11: Power Amplifier (Backplane Connections) 2.1.3 Function of the Fan Module The fan module provides intermittent forced-air cooling for the power amplifier and transceiver modules. The fan module houses two 119 mm axial fans which deliver a total of approximately 160 cubic feet per minute of airflow. Nominal fan speed is 4100 revolutions per minute. A thermostat behind the fan module controls each fan. If the fan speed for either fan falls below 30% of the rated speed, a built-in speed sensor on each fan turns on the red Fan Alarm LED. If the fan module is used for the Power Efficiency Package, the following must be configured in the Configuration/Service Software (CSS) to take full advantage of the Power Efficiency Package:

Optional fan holdover time (length of time the fan stays ON after transmission). Disabling one of the fans within the fan module. See Replacing the Fan Assembly on page 238 for instructions on how to disable one of the fans. Configuring the base radios Tx Power Out in the CSS should be limited to 50 W. The fan module connects to the backplane through a 4-pin port on the front of the chassis. NOTICE: The power supply module has its own fan which provides independent airflow. Figure 12: Fan Module 66 MN003286A01-H Chapter 2: GTR 8000 Base Radio Theory of Operation 2.1.4 Function of the Power Supply The power supply, with front-to-rear airflow, operates from either an AC or DC input and provides the DC operating voltage for the base radio. However the power supply prioritizes an AC source (if present) over a DC source. Figure 13: Power Supply NOTICE: If the power supply module is used for the Power Efficiency Package, the power supply must be used in DC mode to obtain the 35 W standby power consumption performance. When operating from an AC source (90 to 264 VAC, 47-63 Hz), the supply generates two DC output voltages of 29 V with respect to output ground. The power supply automatically adjusts to AC input ranges and supplies a steady output. In AC mode, the power supply may provide a separate battery charger which can be used to maintain the charge on a 48 VDC nominal system, positive or negative ground, if installed. The supply generates two DC output voltages of 29 V with respect to output ground, when operating from a DC source (43.2 VDC to 60 VDC maximum), positive or negative ground. This voltage limit includes consideration of the battery charging "float voltage" associated with the intended supply system, regardless of the marked power rating of the equipment. Whether in AC, Battery Revert, or DC Only mode, at a voltage of 42 V or lower, the power supply shuts down to not damage any connected battery bank. Once this condition occurs, the power supply starts only after the applied voltage exceeds 45 V. The battery charger is not usable when operating from a DC input power source. This DC source must be located in the same building as the base radio, and it must meet the requirements of a SELV circuit. The power supply contains several switching-type power supply circuits as follows:

Power factor correction circuitry Battery charging circuitry Diagnostics and monitoring circuitry The power supply controls its own continuously running fan, changing its speed to fast, or slow as needed. 67 MN003286A01-H Chapter 2: GTR 8000 Base Radio Theory of Operation NOTICE: If the power supply module is used for the Power Efficiency Package, the power supply fan does not run below a 40 C air inlet temperature in DC mode with the transmitter in a de-keyed state. 2.1.4.1 AC/DC Power Distribution Base Radio Figure 14: AC and DC Power Distribution in the GTR 8000 Base Radio If present, the base radio operates from AC power as the preferred power source. When AC power is not available, the base radio switches to operate from the DC source. Operation returns to the AC source when the AC source is restored. Switchover from AC to DC and back again is fully automatic. The Main DC output of the power supply is used to provide power to the power amplifier and the transceiver. The Auxiliary output of the power supply is not used within the base radio, but is reserved for use as a redundant power input to other site components such as the site controller. 2.1.4.2 Power Supply Battery Charger The power supply may include an integrated battery charger. The battery charger is controlled through software residing on the associated device module. Software contains the information on supported battery types and obtains user-specific information pertaining to the particular site. The device software receives battery bus voltage and battery temperature information from the power supply, and uses these variables with supported battery charging profiles to return a signal which sets the charger output voltage appropriately. The battery charge and temperature conditions are viewed through 68 MN003286A01-H Chapter 2: GTR 8000 Base Radio Theory of Operation Configuration/Service Software (CSS) and Unified Network Configurator (UNC), or through alarms to Unified Event Manager (UEM). The maximum charging current available from the integrated charger is 3 A (48 VDC nominal system). A battery with capacity no larger than 60 Ah should be connected to a single charger to ensure that the charger maintains an adequate state-of-charge on the backup battery, and the backup battery is restored to full capacity within a reasonable amount of time following operation on battery backup power. In addition to standard sealed lead-acid batteries (valve-regulated lead acid or gel cells), the power supply supports charging of vented lead-acid and NiCd batteries. 2.1.4.3 Battery Temperature Sensor Cable The integrated charger in the power supply performs temperature compensated battery charging when a temperature sensor is connected. If the sensor is disconnected, the charger continues to operate as an uncompensated charger with the charging profile following the minimum charger voltage specified by the battery manufacturer. Included is a 40 ft battery temperature sensor cable, which attaches to a battery pack, supplied by your organization, and to the backplane of the device. This three-wire cable carries a voltage signal to the power supply from the sensor element, which must be mounted close to the storage battery. Voltage is proportional to the battery temperature, and the diagnostic circuitry in the power supply module. This cable is extended to a total length of 190 ft using 50 ft extensions. See Battery Temperature Sensor Mounting on page 104. IMPORTANT: Continuous operation with a disconnected sensor is not recommended. 2.1.4.4 ON/OFF Switch for Power Supply and Battery Charger This table identifies the switch states for the power supply and battery charger. Table 30: ON/OFF Switch - States for Power Supply and Battery Charger Switch Position Power Supply State Battery Charger State ON (1) DLN6781A can be started if desired (AC input only) DLN6805A Disabled OFF (0) Disabled (AC input only) Power Factor Correction

The following are some examples of the RFDS equipment available for your system. NOTICE: If the RTTE option was selected, a duplexer is required for applicable applications. 2.3.1 RFDS Preselector (700/800 MHz) The preselector provides a first level of band pass filtering for inbound RF signals. RF input and output connectors are cabled to the RF Output RX-A. This filter must be included to fulfill TIA102-CAAB Class A spurious response rejection (90 dB). The filter is not required when using a receiver multicoupler system. This filter CANNOT be retuned in the field. Figure 16: Preselector Filter (700/800 MHz) 2.3.2 RFDS Preselector (UHF) The preselector rejects unwanted signals including the transmitter signals from overloading the receiver.

It includes a cable that connects to the RF Peripherals port on the base radio backplane to provide temperature monitoring. 2.3.11 Antenna Relay Module The antenna relay module allows a single antenna to be used for both transmit and receive functions on a conventional GTR 8000 Base Radio. A signal from the base radio transceiver module controls the antenna relay module. The antenna relay module is typically mounted on the backplane cover on the rear of the base radio, or on the peripheral tray if the base radio is equipped with other options. Figure 25: Antenna Relay Module Connections on page 77 shows the antenna relay module input and output external connections. Settings for the antenna relay module are made through Configuration/Service Software (CSS) and UNC. NOTICE: If the antenna relay is Enabled and it is then disconnected, a failure is generated and logged stating the antenna relay is disconnected. However, the base radio also generates an exciter failure because the antenna relay is controlled and monitored through the exciter module. The exciter failure should be ignored until after the antenna relay failure is corrected. The failures are reported in the Status Report and UEM. 76 Figure 25: Antenna Relay Module Connections MN003286A01-H Chapter 2: GTR 8000 Base Radio Theory of Operation 2.3.11.1 Mounting Locations The antenna relay module may be installed in either of two locations. On base radios not equipped with the peripheral tray, the antenna relay is mounted on the backplane cover. Figure 26: Base Radio Backplane Mounting Location 77 MN003286A01-H Chapter 2: GTR 8000 Base Radio Theory of Operation Figure 27: Antenna Relay Module Mounted on Backplane Cover On base radios equipped with the peripheral tray, the antenna relay is mounted on the peripheral tray. 78 Figure 28: Antenna Relay Module Mounted on Peripheral Tray MN003286A01-H Chapter 2: GTR 8000 Base Radio Theory of Operation 2.3.11.2 Functional Operation The antenna relay module contains a relay with a set of normally open and normally closed contacts. A signal from the transceiver module controls the relay coil connected to the Receiver input port RX-A or the PA deck to a single transmit/receive antenna. NOTICE: With the relay de-energized, the antenna is connected to the Receiver input port RX-

A. To connect the antenna to the PA deck, the transceiver module must energize the relay. 79 MN003286A01-H Chapter 2: GTR 8000 Base Radio Theory of Operation Figure 29: Functional Block and Interconnect Diagram for Antenna Relay Module (Bracket Mounting) 80 MN003286A01-H Chapter 2: GTR 8000 Base Radio Theory of Operation Figure 30: Functional Block and Interconnect Diagram for Antenna Relay Module (Peripheral Tray Mounting) 81 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation Chapter 3 GTR 8000 Base Radio Installation This chapter details installation procedures relating to GTR 8000 Base Radio.

If additional equipment is installed, see the system design document the field engineer provided, or consult the Motorola Solutions Field Representative. Subsystem cabinets are self-supporting structures. In areas subject to seismic activity, additional bracing of the cabinet may be required to prevent it from tipping. However, the bracing hardware must be locally procured. No specific procedures are provided within this manual for bracing cabinets in active seismic areas. See the Motorola Solutions Standards and Guidelines for Communication Sites manual for details on seismic conditions. 88 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation 3.3.5 Mounting Cabinets or Racks to a Floor When and where to use: Perform the following steps to properly install a cabinet or open rack within a site building. Secure the cabinets and racks to the floor for optimum stability. This procedure is written so that the cabinet or rack is moved only once. Procedure:

footprint. 1 Carefully mark the mounting holes with a pencil, as indicated on the appropriate cabinet or rack 2 Drill the marked mounting holes to the appropriate depth of the mounting hardware with a hammer drill and bit. 3 Insert an anchor into the drilled hole. If necessary, tap the anchor into place using a hammer. 4 For cabinets, remove the four screws securing the bottom kick panel to the front and back of the cabinet. Remove the kick panel and set aside during installation. 5 Carefully move the cabinet or rack into the position indicated by the holes in the floor. WARNING: Equipment cabinets and racks are heavy and may tip. Use extreme caution when moving. Lift from top eyenuts with the appropriate apparatus, or secure the cabinet or rack from tipping if lifting from the bottom. Failure to do so could result in death or serious injury or equipment damage. 6 Adjust and level the cabinet or rack as necessary to position the cabinet mounting holes with the pre-drilled holes. 7 Secure the cabinet or rack to the site floor with the locally procured mounting hardware. IMPORTANT: If securing the cabinet or rack to a concrete floor, use 1/2-inch grade 8 bolts with anchors. 3.3.6 General Bonding and Grounding Requirements Cabinets and racks include a Rack Grounding Bar (RGB) with the capacity to terminate numerous ground wires. Attach equipment added to the cabinet or rack to the ground bar using solid or stranded 6 AWG copper wire. The RGB uses dual-hole lugs to terminate ground wires. The minimum number of dual-hole attachments is system-dependent and specified by the customer. This bar provides electrical continuity between all bonds and ground wire with a current-carrying capacity equal to or exceeding that of a 6 AWG copper wire. See the Motorola Solutions Standards and Guidelines for Communication Sites manual for more information on proper bonding and ground at a site. 3.3.7 General Cabling Requirements Diagrams for cabling are typically included in the system-specific configuration documentation Motorola Solutions provides. Also see the Motorola Solutions Standards and Guidelines for Communication Sites manual for cabling standards. IMPORTANT: System certification was completed using shielded cables. To prevent emission problems, use only shielded cables. Do not substitute other cable types. 89 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation Position the equipment to avoid excessive tension on cables and connectors. Cables must be loose with absolutely no stress on the connectors. Careful cable routing and securing the cables with tie wraps (or other devices) is one way to provide this protection. Set up preventive maintenance loops. Dress the cables neatly using cable ties. Do not tighten the cable ties until you are sure that the required service length and bend radius requirements are met. Leave cable ties loose enough to allow adjustment. Verify that all cables are properly labeled to match System-specific configuration documentation Motorola Solutions provided. Ensure that cables do not exceed the minimum bend radius as outlined in the Motorola Solutions Standards and Guidelines for Communication Sites manual. CAUTION: Use only Category 5 Shielded Twisted Pair (or higher) for cabling Ethernet connections. Motorola Solutions has engineered this system to meet specific performance requirements. Using other cabling and connectors may result in unpredictable system performance or catastrophic failure. NOTICE: For more information on cabling guidelines, see the documentation supplied with components from each equipment manufacturer. 3.3.8 General Power Guidelines and Requirements See the Motorola Solutions Standards and Guidelines for Communication Sites manual for information on providing electrical service, power budgeting, selecting batteries, and other topics for supplying power at the site. Perform electrical installation work in accordance with the current edition of the NFPA 70 and local building codes. Where required, use a qualified and licensed electrician for all electrical installations. 3.3.8.1 General AC Power Guidelines and Requirements The Motorola Solutions Standards and Guidelines for Communication Sites manual defines the guidelines and requirements for cabinets and racks which house equipment that requires AC power input. Some of the guidelines and requirements are as follows:

The cabinet or rack is designed to accept 120/240 V, single-phase power with an amperage service size as required by the electronic equipment. Cabinets and racks powered by commercial power must be equipped with a Nationally Recognized Test Laboratory (NRTL) certified power distribution module that contains a main circuit breaker or individual circuit breakers of the correct size as required for the electronic equipment or as the customer specified. A decal showing an electrical schematic of the power wiring is affixed to the inside surface of the cabinet. All AC power equipment and electrical components must conform to National Electrical Manufacturers Association (NEMA) and National Electrical Code (NEC). The AC power equipment must also be listed by an NRTL. A surge arrestor, designed to protect equipment systems from a 120/240 V service and load center, is placed on the power feed ahead of all individual load center circuit breakers. This gapless arrestor must be listed by an NRTL for the purpose intended. Selection of a surge arrestor is based on the susceptibility of the equipment powered by the electrical service, with margin provided for locally generated disturbances. See ANSI/IEEE C62.41

(21) for more details. 90 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation At least one 120 VAC, 15 A duplex convenience outlet equipped with Ground Fault Interrupter (GFI) protection must be provided in the electronic equipment compartment. CAUTION: Do not use surge/transient suppressors without careful and expert power system analysis. NOTICE: Redundant devices could be terminated on different AC main phases so that a single phase failure does not result in a power loss for both devices. 3.3.8.2 General Breaker Recommendations To ensure that a fault which causes the breaker to open does not result in the loss of multiple transmit channels, each power supply should have its own supply breaker. The breaker recommendations for AC and DC supply breakers are as follows:

For a 120 VAC, 60 Hz application, the AC supply breaker must be rated for a continuous current of 20 A. For a 220 VAC, 50 Hz application, the AC supply breaker must be rated for a continuous current of 10 A minimum, not to exceed 20 A. Individual DC breakers are not used. For information involving the sizing of cables and DC power distribution, see the Standards and Guidelines for Communication Sites manual. Site installation must include a single current interrupting device on the DC input distribution (fuse or circuit breaker) rated for the application loading, not to exceed 200 A. For each standalone device, the DC supply breaker should be rated for a continuous current of 25 A. 3.3.8.3 General Battery Installation Recommendations Position the batteries and charger as closely as possible to the rectifier system using the cables. Use a heavy gauge stranded cable to minimize voltage drop. Examples of the resistance of some heavy gauge wire are:

Table 33: Heavy Gauge Wire Resistance Examples Gauge

#6 gauge

#4 gauge

#2 gauge Resistance 0.3951 /1000 ft 0.2485 /1000 ft 0.1563 /1000 ft The maximum voltage drop can be calculated by knowing the peak current the radio system draws. Use the following formula:

Total Voltage drop = [/1000 ft] x [total loop length (ft)] x [Ipeak (A)] + [connector(s) voltage drop(s)]

See DC Power Connection Wire Gauge Calculations for Integrated Voice and Data on page 102 and DC Power Connection Wire Gauge Calculations for HPD on page 103 for additional guidelines on the cable sizing. 3.3.9 General Electrostatic Discharge Recommendations Electronic components, such as circuit boards and memory modules, can be sensitive to Electrostatic Discharge (ESD). Use an antistatic wrist strap and a conductive foam pad when installing or upgrading the system. 91 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation If an ESD station is not available, wear an antistatic wrist strap. Wrap the strap around the wrist and attach the ground end (usually a piece of copper foil or an alligator clip) to an electrical ground. An electrical ground can be a piece of metal that literally runs into the ground (such as an unpainted metal pipe), or the metal part of a grounded electrical appliance. An appliance is grounded if it has a three-

prong plug and is plugged into a three-prong grounded outlet. NOTICE: Do not use a computer as a ground, because it is not plugged in during installation. 3.3.10 FCC Requirements Radio frequency (RF) transmitters installed at sites within the US must be in compliance with the following FCC regulations:

The station licensee is responsible for the proper operation of the station at all times and is expected to provide observations, servicing, and maintenance as often as may be necessary to ensure proper operation. The transmitter ERP must not exceed the maximum power specified on the current station authorization. The frequency of the transmitter must be checked during initial installation of the transmitter, when replacing modules, or when making adjustments that affect the carrier frequency or modulation characteristics. 3.3.11 Networking Tools Use the following networking tools for installing and servicing the network:

However, provide all cabinets and racks with sufficient floor space to permit access for installation and service. Clearance required for service and installation is at least 2 ft in the front and rear. At least 2 ft floor access in front of the cabinet or rack. Front access:

94 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation Side and rear access:

At least 2 ft floor access at the rear of the cabinet or rack, or At least 2 ft access on at least one side of the cabinet or rack, plus 6 inches at the rear of the cabinet or rack. To maintain this clearance, the following is required:

If there is less than 2 ft rear access, do not install more than two cabinets or racks side by side, and allow at least 2 ft access on at least one side of each cabinet or rack. For the cabinet version, if there is less than 2 ft rear access, do not install the optional rear door on the cabinet. NOTICE: For the cabinet version, when an eyenut has to be replaced, provide at least 2 ft access to both sides of the cabinet so that both side panels can be removed. 3.4.2 Cabinet Version of the GTR 8000 Base Radio The GTR 8000 Base Radios are offered with factory cabinet options for mounting flexibility. Two cabinet height options are available:

31 in. 15 Rack Units (Option CA02446AA) 47 in. 24 Rack Units (Option CA02447AA) Each cabinet is ordered with a single base radio and Radio Frequency Distribution System (RFDS) equipment pre-installed. Additional base radios and other devices are installed in the cabinet during field installation. For spacing equipment or placing peripherals between base radios, additional slides rails can be ordered. The cabinets have knockouts on the top and bottom that provide space and separation of cable types when routing the cables. Follow the Motorola Solutions Standards and Guidelines for Communication Sites manual for the multiple knockouts for the different cable types as shown in Figure 33: Cabinet Dimensions on page 97. The doors on both cabinets are provided with standard locks (key# 2135), which come with two keys per lock. Each door can also be detached and mounted on a reverse direction. 3.4.2.1 Floor Mounting the Cabinet Version of the GTR 8000 Base Radio Securely fasten the cabinet to the floor or other rigid surface capable of supporting the load of the cabinet. 95 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation Figure 32: GTR 8000 Base Radio (Cabinet Version) Floor Mounting Detail IMPORTANT: The four 5/8 in. holes in the top of the cabinet are for stacking cabinets and are not intended for strength when lifting a cabinet. 3.4.2.2 Physical Dimensions and Clearances of the Cabinet Version of the GTR 8000 Base Radio The figures show the dimensions for both the 31 in. and 47 in. cabinets. Minimum recommended clearances are 36 in. (front and rear) for installation access. 96 Figure 33: Cabinet Dimensions MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation 3.4.2.3 Cabinet Mounting Rails The figures show the dimensions and spacings of the mounting rails inside both the 31 in. and 47 in. cabinets. The mounting rails are square hole and require cage nuts for additional equipment installation. 97 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation Figure 34: Cabinet Mounting Rails Motorola Solutions made no provision to enable the removal of a harness after the equipment has been lifted and placed flat onto a surface. Your organization must provide those provisions. 3.4.2.4 Vertical Lifting of Cabinets 3.4.2.4.1 Lifting Cabinets Vertically When and where to use: Use this procedure to lift the cabinet with a harness and place onto a flat surface. Procedure:

1 Place two temporary supports onto the floor or flat surface. Position the supports to facilitate the removal of harness. See Figure 35: Lifting a Cabinet with a Harness on page 99. 98 Figure 35: Lifting a Cabinet with a Harness MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation 2 Using the harness, lift the cabinet onto the two supports. 3 Remove the harness. onto the flat surface. 4 Lift one side of the cabinet slightly and remove one of the supports. Carefully lower the cabinet 5 Lift the other side of the cabinet slightly and remove the other support. Carefully lower the cabinet onto the flat surface. 3.4.2.5 Removing/Replacing a Cabinet Door When and where to use: The default orientation of the door hinge is on the right side of the cabinet. Use this procedure to change the hinge to the left side of the cabinet, or to replace a cabinet door. Procedure:

1 Loosen the M6 fastener and detach the ground cable from the bus bar. If removing the front cabinet door, the ground cable is detached from the M6 nut in the cabinet body. 99 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation Figure 36: Cabinet Door Removal 2 To remove the door, release the spring loaded latch. 3 Lift the door from the pin hinge. Figure 37: Cabinet Door Replacement 100 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation 4 Flip the door 180 and reattach it to the cabinet with the pin hinge. 5 Reattach the ground cable to the M6 nut in the cabinet body. 3.4.3 Rack Mounting The GTR 8000 Base Radio Mount the base radio housing in a rack that has been secured to the floor. For open racks, two brackets are required to distribute the weight. Without brackets, the center of gravity of the system shifts to the back, potentially causing structural issues with the rack. The brackets come with the required number of screws. Figure 38: Base Radio Mounted in Rack NOTICE: Perform this installation with two people so that one person can hold the device in place while the other person attaches the brackets to the rack. 3.4.3.1 Mounting the GTR 8000 Base Radio Procedure:

1 Determine where to mount the device on the rack and mark the location. The brackets are useful in making this determination, and the pin on the back of the bracket helps in finding the exact location on the rack. 2 Attach the brackets to the sides of the chassis:

a Use M6x1x13 machine screws with a captive washer (zinc plated). b Screw one bracket into the clinch nuts on the side of the chassis. c Screw the second bracket into the clinch nuts on the other side of the chassis. 101 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation 3 Lift the device into place on the rack using the pins on the brackets to properly line up the 4 Attach the two brackets to the rack:

a Screw two M6x1x10 thread-forming screws (black finish) through the front holes on one side of the chassis and into the bracket. b Screw two M6x1x10 thread-forming screws (black finish) through the front holes on the other side of the chassis and into the bracket. 3.4.4 Connecting Power This section covers topics on connecting power cables to the base radio, calculating the length of wire for various gauges, and mounting the battery temperature sensor. 3.4.4.1 Connecting Power Cables to a GTR 8000 Base Radio For standalone base radios, AC and DC inputs, provided by your organization, connect to the power supply through the backplane of the base radio. See GTR 8000 Base Radio Rear Connections

(Integrated Voice and Data) on page 106, GTR 8000 Base Radio Rear Connections (HPD) on page 109, and GTR 8000 Base Radio Front Connections on page 111. 3.4.4.2 DC Power Connection Wire Gauge Calculations for Integrated Voice and Data Because the power supply disconnects itself from the DC input when it senses that DC voltage has dropped to 42 VDC, it is important to minimize the voltage drop in the DC power supply loop (the total length of the 48 VDC hot wire and the DC return wire) to no more than 1 V total. Minimizing the voltage drop ensures that the maximum energy is removed from the battery before disconnecting the power supply from the DC input line. A base radio transmitting at 100 W draws up to 10 A* current when operating from a 54 V source

(nominal 48 VDC system). As voltage decreases (due to the standby battery discharging) the current increases proportionally (because the base radio appears to be a constant power load). At the low voltage disconnect point (42 V for a nominal 48 VDC system), the current is up to 13 A*. If a single pair of 2 AWG wire is used to connect the battery to the back panel, the maximum length of a single conductor would be 75 m (245 ft). Use of smaller gauge wire would reduce this length depending on the resistance of the wire.

* = The actual current value can be calculated from the power consumption value in the specifications tables. See GTR 8000 Base Radio Specifications on page 40. To determine the maximum length of wire for wire other than 2 AWG, the following relationship can be used:

102 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation Length (m/ft) = V/I/R where:

V = voltage drop in one leg of the loop (max = 0.5 V) I = current the base radio draws during DC operation R = resistance of the wire being considered (in Ohms per ft) For common wire sizes, the maximum distances shown in Table 34: DC Power Connection Wire Gauge Maximum Distances for an IV and D Site on page 103 apply. Table 34: DC Power Connection Wire Gauge Maximum Distances for an IV and D Site AWG Resistance (ohm/304.8 meter/ 1000 ft) Maximum Distance (for 13A) 2 3 4 5 6 0.1563 0.1970 0.2485 0.3133 0.3951 75 m (245 ft) 60 m (195 ft) 47 m (155 ft) 37 m (120 ft) 30 m (95 ft) 3.4.4.3 DC Power Connection Wire Gauge Calculations for HPD Since the power supply disconnects itself from the DC input when it senses that DC voltage has dropped to 42 VDC, it is important to minimize the voltage drop in the DC power supply loop (the total length of the 48 VDC hot wire and the DC return wire) to no more than 1 V total. Minimizing the voltage drop ensures that the maximum energy is removed from the battery before disconnecting the power supply from the DC input line. A base radio transmitting at 50 W draws up to 7.4 A current when operating from a 54 V source

(nominal 48 VDC system). As voltage decreases (due to the standby battery discharging) the current increases proportionally (since the base radio appears to be a constant power load). At the low voltage disconnect point (42 V for a nominal 48 VDC system), the current will be up to 9.5 A. Use of smaller gauge wire would reduce this length depending on the resistance of the wire. To determine the maximum length of wire for wire other than 2 AWG, the following relationship can be used:

Length (ft) = V/I/R where:

V = voltage drop in one leg of the loop (max = 0.5 V) I = current drawn by the base radio during DC operation (9.5A) R = resistance of the wire being considered (in Ohms per ft) For common wire sizes, the maximum distances shown in Table 35: Power Connection Wire Gauge Maximum Distances for HPD on page 103 apply. Table 35: Power Connection Wire Gauge Maximum Distances for HPD AWG Resistance (ohm/1000 ft) Maximum Distance 2 3 4 0.1563 0.1970 0.2485 102m (335 ft) 81m (265 ft) 64m (210 ft) 103 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation AWG Resistance (ohm/1000 ft) Maximum Distance 5 6 0.3133 0.3951 51m (165 ft) 40m (130 ft) 3.4.4.4 Battery Temperature Sensor Mounting A 40 ft battery temperature sensor cable is shipped with your device. This three-wire cable carries a voltage signal to the power supply from a sensor element which must be mounted close to the storage battery. Voltage is proportional to the battery temperature and the diagnostic circuitry in the power supply module. The 40 ft cable can be extended to a total length of 190 ft using 50 ft extensions

(Motorola Solutions part number 3084827Y04. See Motorola Solutions Support Center on page 220. Mount the sensing element of the temperature sensor so that it detects the actual battery temperature

(or the ambient temperature as close as possible to the batteries being charged). The two examples of mounting are as follows:

Example 1 Use cable ties to attach the sensing cable to the positive (or negative) power cable. A minimum of two cable ties should be used (spaced 6 inches apart), with one of the cable ties not more than 2 inches from the sensing element. Mount the sensing element not more than 2 inches from the battery post where the power cable connects. See Figure 39: Battery Temperature Sensor Example 1 on page 104. Figure 39: Battery Temperature Sensor Example 1 Example 2 104 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation Attach the sensing cable to an existing battery tray support bracket using cable ties or nylon loop straps of the proper size. Mount the sensing element not more than 2 inches from the surface of the batteries being monitored. Use a minimum of two cable ties and/or loop straps to secure the sensing cable to the bracket. Place the cable ties/ loop straps no more than 6 inches apart with one placed no more than 2 inches from the sensing element. See Figure 40: Battery Temperature Sensor Example 2 on page 105. Figure 40: Battery Temperature Sensor Example 2 3.4.5 GTR 8000 Base Radio Grounding Detailed grounding information is beyond the scope of this manual. See the Standards and Guidelines for Communication Sites manual for detailed information about grounding and lightning protection. IMPORTANT: Ground the battery system, either positive or negative, at the battery. The DC input (battery charger output) of the power supply floats with respect to earth ground. The power supply can therefore be used in either positive ground or negative ground DC systems. Connect the appropriate terminal (+ or -) of the DC system to protective earth at the battery. These instructions assume that all telephone lines, antenna cables, and AC or DC power cables have been properly grounded and lightning-protected. When rack installations have a primary rack and one or more expansion racks, all these racks must be connected to the same Sub System Ground Bus Bar (SSGB) (with no other rack connected to the SSGB). Grounding ensures that surge events do not produce ground potential differences that affect signals between the racks. 105 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation The backplane has a double lug with two lock nuts on the rear panel where the ground wire connects to the backplane on one end, and to the rack grounding bar on the other. The rack grounding bar is connected to the master ground bus bar. To use the grounding lugs, a length of #6 AWG wire with UL-listed ring lugs is required on both ends. This wire is shipped with the device. For the cabinet version of the base radio, the rack grounding bar is connected to the SSGB with a provided AWG2 dual hole lug.

NOTICE: Beginning with ASTRO 25 system releases 2019.x, see the "Installing Device Software Prerequisites" and related sections in the GTR 8000 Expandable Site Subsystem Feature Guide. 1 Transfer and install new software to a device using the Software Download Manager. See Software Download Manager on page 124. 2 Obtain the ASTRO25 media. Specifically, you need the Motorola Solutions Device OS Image media. See Loading Device OS Images to the UNC on page 127. Process:

122 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation 3 Obtain user names, passwords, and procedures required to access the devices on the network. For specific user names and passwords to access devices on the network, contact your system administrator. 4 Set up the users in the IT Admin group in Active Directory Users and Computers. See the Authentication Services manual. 5 Obtain the following values from the system administrator:

Line interface number Zone Controller (ZC) site link path 1 IP address ZC site link path 2 IP address Host name to access the Unified Network Configurator (UNC) server application using Secure SHell (SSH) (<username> @IP address format) Site ID number IP address 1 and 2 Primary and secondary NTP IP addresses NOTICE: The following are applicable to systems with Authentication, Authorization, and Accounting (AAA) Servers, Domain Controllers, or Syslog Servers. Primary, secondary, and tertiary Domain Name Services (DNS) IP addresses Requested DNS Domain Name Requested DNS Host Name System Name Primary SYSLOG Service Name Fully Qualified Domain Name (FQDN) Backup SYSLOG Service Name Fully Qualified Domain Name (FQDN) Remote Authentication Dial-In User Service (RADIUS) FQDN parameter value RADIUS Row Status parameter value RADIUS Service Time Out (seconds) parameter value RADIUS Service Retransmits Attempts parameter value RADIUS Service Dead Timer (min) parameter value RADIUS Specific Key parameter value RADIUS Service Global Key parameter value 6 Obtain the default credentials (local accounts, central authentication, and SNMPv3) for the device being installed, as well as the updated passwords for those types of accounts (so that you can change the password after you install the device). Contact your system administrator, if you do not have this information. See the SNMPv3 manual or see Local Password and SNMPv3 Passphrase Troubleshooting on page 219 for more information. 7 Configure the device as a RADIUS client on the RADIUS server. When these devices are configured with a RADIUS key that matches a shared secret for that device in Microsoft Windows Internet Authentication Service (IAS), they become RADIUS clients. They do not join the Active Directory domain. See the Authentication Services manual for more information. 8 NOTICE: This step is applicable to systems with AAA Servers, Domain Controllers, or Syslog Servers. To use the VoyenceControl component of the Motorola Solutions centralized configuration application for any of the site device procedures, set up the UNC. Depending on your organizational policies, you may also need to implement a secure protocol between the UNC 123 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation and the site device. Before performing any procedures using VoyenceControl, the device must be discovered in VoyenceControl, and the device configurations must be recently pulled to the UNC database. See the following ASTRO 25 system documentation: Unified Network Configurator manual and Securing Protocols with SSH manual. NOTICE: The names EMC Smarts Network Configuration Manager and VoyenceControl are used interchangeably for this product. 3.7 Software Download Manager The Software Download Manager (SWDL) is an application that can transfer only, install only, or transfer and install new software to devices. The new software can be installed either locally at a site or on the Network Management subsystem. Individual devices not connected to the system can be downloaded using single device mode. NOTICE: Throughout this manual, the name SWDL is used to refer to the Software Download Manager application. Software Download Security Transfer Modes A software download can be performed using the following security transfer modes:

Transfers the software without security, based on the File-Transfer Protocol (FTP) Clear SWDL Secure SWDL Transfers the software as encrypted, based on the Secure File-Transfer Protocol (SFTP) NOTICE: All secure sequential and simultaneous transfers use the Diffie-Hellman group exchange. The Diffie-Hellman group exchange is used for devices supporting Diffie-Hellman group exchange. The Diffie-Hellman group exchange enhances the security of Secure Shell

(SSH) protocol initial key exchange. See the Software Download Manager manual for details. Before initiating transfer, SWDL connects to the site in the zone to discover all devices. The transfer mode of all devices is displayed in the SWDL window. It is important that all devices have the same SWDL transfer mode. Otherwise, SWDL flags a mismatch of the SWDL transfer modes across site devices. SWDL provisions the credentials for Secure SWDL as part of initiating the SWDL operation. No user intervention is required. For a single device, Secure or Clear SWDL is configured based on the SWDL Transfer Mode configuration within the Configuration/Service Software (CSS). The Unified Network Configurator (UNC) can be used to schedule and configure all devices in the system at once. For information on how to configure the secure or clear SWDL transfer mode, see the Unified Network Configurator manual and Configuring Devices for Security in the CSS Online Help. Software Download Transfer Methods A software download can be accomplished in two ways:

Site Software Download Allows you to transfer and install application software from any location within a network. The Software Download Manager resides on the Network Management Client computer and a service computer/laptop loaded with the CSS application. From either of the computers, you can select device types to download software. Site Software Download allows you to select the zone, site, device types, and software download operation to perform. When performing a site software download, the site controller coordinates the software transfer for all trunked base radios, receivers, comparators, and reference distribution modules installed at the site. A site software download can only be performed on a trunked ASTRO 25 system. 124 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation NOTICE: Trunked GPW 8000 Receivers in a circuit simulcast configuration are not supported using a site software download. Single Device Software Download Allows you to transfer and install software to a single instance of a device (such as one base radio). This feature gives the technician the ability to install different versions of software. Single device software download is done from a service computer/laptop loaded with the CSS application either connected directly to the device or connected to the network. NOTICE: Conventional devices and 3600 base radios are supported only in single device software download. Site Software Download Functionality When SWDL is connected from a central remote location, SWDL performs a site software download to the site controllers, then to the comparators and base radios or receivers installed at the site. Both active and standby site controller modules have two flash memory banks for storing software. The device application is run from RAM, and is loaded from the active flash memory bank after a reset. One bank is active while the other bank is inactive. The transfer of the software using SWDL is a background process, without interruption of services at the site, that loads the software into the inactive bank. The site controller executes the software from one bank, while software is simultaneously downloaded to the inactive bank. The transfer and install are done in the background. An install causes the site controller to reset and load the RAM from the bank that was installed with the new software. NOTICE: For geographically redundant prime sites, a site software download should not be attempted while the third Site Controller (SC3) is in the active state. SWDL communicates with the site controllers to determine the number of existing remote sites and the number of channels. SWDL considers a channel or remote site to be accessible if its status is Not Unconfigured. This term means that the site must be set up with a service computer/laptop with CSS or a network management client before software download is performed on the site. The system downloads software to the site controllers, comparators, base radios, or receivers as a unit. Use SWDL to transfer software to each device type, then perform an install operation. During the transfer, the operation designates a proxy for each device type at each LAN. Site controllers proxy for comparators, and base radios or receivers proxy for each other. The proxy cross-transfers the software to other devices on the LAN. Using proxies minimizes system downtime. Transfers to the LAN are done simultaneously except for the site controller and comparators. Software installation is done on a channel-by-channel basis, starting with the highest number channel. When a channel software download occurs, the base radio or receiver which incorporates that channel is processed along with the comparator for that channel. For example, if channel 3 was being downloaded, comparator 3 and the base radios or receivers for channel 3 at each of the remote sites would be installed simultaneously. SWDL operation can be fault managed through Unified Event Manager (UEM), syslog, local SWDL log files, user messages, and device reports. For further information on SWDL, see the Software Download Manager manual. The operating software can also be loaded using the UNC. See the Unified Network Configurator manual to perform single device software downloads (ruthless download) to the devices. See the G-Series Equipment System Release User Guide for SWDL instructions specific to the operating characteristics of your existing system release. 125 MN003286A01-H Chapter 3: GTR 8000 Base Radio Installation 3.8 Installing Devices in the UNC When and where to use: The Unified Network Configurator (UNC) is the Network Manager used to discover a device and load Operating System images.

Updating factory-installed base radio application software Setting parameters in a configuration file stored on the GTR 8000 Base Radio that impacts both base radio and RF Distribution System (RFDS) functionality. This chapter details configuration procedures relating to the base radio. 4.1 Configuration Software Configuration of a device can be done on two software applications: Configuration/Service Software

(CSS) and Unified Network Configurator (UNC). CSS UNC Wizard is used to configure the parameters on the device. CSS can access devices remotely over the network, or locally through an Ethernet/serial connection to the service port on the device or through a LAN switch. CSS also can be used to view status information, equalize batteries, and check internal logs of the equipment at the site. See the CSS Online Help for configuration details. is a component of UNC used to configure the parameters of a site, subsite, and channel. See the UNC Wizard Online Help for configuration details. VoyenceControl/EMC Smarts is a component of UNC used to pull and push configurations and configure the parameters of the device. See the Unified Network Configurator manual for general information about using VoyenceControl/EMC Smarts functions. NOTICE:

The UNC is not applicable for K core or non-networked sites. While it is possible to configure a conventional device using the UNC, it is preferable to use CSS because configuration dependencies are enforced. Beginning with ASTRO 25 system releases 2019.x, VMware Smart Assurance Network Configuration Manager replaces the EMC Smarts Network Configuration Manager. See the

"Configuration Software" section in the GTR 8000 Expandable Site Subsystem Feature Guide. All parameters are programmed locally when the site is installed but not linked to a network. Test all parameters before making the site available. The ability to locally program provides the means to test the site before making it available for system operation. 4.2 Discovering a Device in the UNC When and where to use: Use these high-level steps to discover the devices in the Unified Network Configurator (UNC). See the Unified Network Configurator manual for details on discovering devices. Process:

If the Elevated Privileges Password field is active, enter the Elevated Privileges Password that was set up for this device. When accessing the device, if the default passwords do not work, the passwords may have been set to default values by a different system release of software. See "Resetting Device Passwords" in the CSS Online Help to reset the passwords to the current software release defaults. If Authentication Services are not enabled on a device, type any alphanumeric characters to populate the [Username, Password, and Elevated Privileges Password] fields, as they cannot be left blank. 9 To access the device and close the dialog box, click OK. The blank CSS main window appears. NOTICE: The Service menu is not available until you read the configuration file from the device using an Ethernet connection. 137 MN003286A01-H Chapter 4: GTR 8000 Base Radio Configuration 4.4.3 Serial Connection Configurations The following procedures set configuration parameters in the Configuration/Service Software (CSS) using a serial connection. 4.4.3.1 Setting the Device IP Address and Pairing Number in CSS Prerequisites: Obtain the required credentials information (local service account password and elevated privileges password) to configure the site devices before proceeding. The user credentials information includes both the current and new credentials. Without the current credentials, access to the device or to the user credentials is denied. See Local Password and SNMPv3 Passphrase Troubleshooting on page 219. NOTICE: Setting or changing the device IP Address causes the SNMPv3 configuration and user credentials to automatically reset. Procedure:

1 Connect to the device using Configuration/Service Software (CSS) through a serial port link. See Connecting Through a Serial Port Link on page 136. 2 From the menu, select Tools Set IP Address/BR_CM Pairing Number. NOTICE: If the device is not in a voting or simulcast IP only topology, the menu item is shown as Set IP Address/Box Number.

SNMPv3 user credentials reset to their factory default values. 8 To reconfigure the SNMPv3 user credentials, see Changing SNMPv3 Configuration and User 7 Click Close to close the dialog box. Credentials in CSS on page 144. 4.4.3.2 Pairing To a Comparator When operating in a voting, multicast, or IP simulcast configuration, base radios must be paired to comparators using the BR/CM Pairing Number. The BR/CM Pairing Number for the base radio and comparator is used to create an IP multicast group that allows the base radio and comparator to talk to each other. The base radio listens for messages that the comparator sends to establish an IP connection with all the paired base radios. When the base radio receives the message from the comparator, it extracts the comparator IP address from the message and uses it to send received voice and data back to the comparator. Communication from the comparator to the paired base radio always uses a multicast IP address. Communication between the paired base radio to the comparator always uses a unicast IP address. 138 MN003286A01-H Chapter 4: GTR 8000 Base Radio Configuration The multicast IP address is calculated based on the base radio and comparator pairing number and the formula as follows:

For Conventional Systems:

224.10.100.nnn, where nnn is: (2 * channel number) - 1 for channel number between [1, 127]

224.10.101.nnn, where nnn is: (2 * (channel number 127) - 1) for a channel number between [128, 200]

For Trunked Multi-Site Systems:

224.100.102.nnn, where nnn is: 100 + (2 * channel number) - 1 NOTICE: The BR/CM Pairing Number is not used for circuit (V.24 or 4-wire/V.24 hybrid link) configurations. See Setting the Device IP Address and Pairing Number in CSS on page 138 to set the pairing number. The pairing number can also be set using an Ethernet connection. See Setting the BR/CM Pairing Number in CSS on page 143. 4.4.3.3 Serial Security Services in CSS The Serial Security Services in Configuration/Service Software (CSS) enables the secure services and changes the device password. NOTICE: The Serial Security Services must be set before changing the SNMPv3 configuration and user credentials on a selected device in the site. Before enabling this parameter, any login and password may be used on the File Transfer Access Services login window to access a device. After Authentication Services are enabled, the login and password provided is checked against the following authentication sources:

Stored password RF site devices support a configurable password for the Local Service and Elevated Privileges accounts. The password is verified against the stored password for these accounts. Built-in logins and passwords RF site devices support built-in login/password combinations for a login by services such as the software downloads. Only certain software download login names are authenticated in this way. Centralized Authentication For authentication through centralized accounts instead of Local Service, Elevated Privileges, and built-in user accounts, use the Configure the Centralized Authentication parameter in CSS for the Challenge Handshake Authentication Protocol (CHAP). See Enabling/Disabling Centralized Authentication with CSS in the Authentication Services manual. This procedure requires an Ethernet connection to the device being configured. 4.4.3.3.1 Setting the Serial Security Services in CSS Prerequisites: Obtain the required credentials information (local service account password and elevated privileges password) to configure the site devices before proceeding. The user credentials information includes both the current and new credentials. Without the current credentials, you cannot access the device and cannot change the user credentials. See Local Password and SNMPv3 Passphrase Troubleshooting on page 219. Changing to the incorrect user credentials may lead to not being able to access the device through Configuration/Service Software (CSS) or Secure Shell (SSH). 139 MN003286A01-H Chapter 4: GTR 8000 Base Radio Configuration Procedure:

See Motorola Solutions Support Center on page 220. This chapter contains optimization procedures and recommended settings relating to GTR 8000 Base Radio. 5.1 Aligning the Internal Frequency Reference Oscillator The transceiver option card within a base radio provides an internal 10 MHz frequency reference which can be used as the primary or backup frequency reference source for the device. For conventional base radio operation, it also provides the analog interfaces and wildcard I/Os. After a base radio is installed or after the transceiver option card is replaced, align the internal frequency reference oscillator. Align the transceiver option card internal frequency reference oscillator to within 1 ppb (parts per billion). The measuring equipment used to make this alignment must be accurate to within 1 ppb. This accuracy typically requires test equipment with a double oven or a Rubidium reference oscillator. NOTICE: The base radio must be turned on for at least one week before the internal frequency reference oscillator is aligned. Align the internal frequency reference oscillator for an Oven Controlled Crystal Oscillator (OCXO) transceiver option card:

Upon installation of the base radio for all bands. Once every two years after installation for 700/800 MHz systems. Once every five years after installation for UHF systems. VHF systems do not require alignment after initial installation. Align the internal frequency reference oscillator for a Temperature Compensated Crystal Oscillator

(TCXO) transceiver option card:

Upon installation of the base radio for UHF. Every year after installation for UHF. The internal frequency reference oscillator can be aligned using two methods: manual alignment or auto alignment. See Base Radio Service Help Service Screens Alignment Screens in the CSS Online Help for the alignment procedures. 157 MN003286A01-H Chapter 5: GTR 8000 Base Radio Optimization 5.1.1 GTR 8000 Base Radio Time and Frequency Inputs Various external time and frequency inputs can be provided to the base radio for normal operation or for Internal Frequency Reference Oscillator alignment.

Sites equipped with storage batteries that provide power in case of primary power failure require that the battery cells be equalized periodically. See Base Radio Service Help Service Screens Alignment Screens in the CSS Online Help for the alignment procedures. NOTICE: Some batteries do not require equalization. See the battery manufacturer recommendations. 5.3 ASTRO Simulcast Alignment (Trunked Operation) ASTRO 25 Simulcast Alignment is used to enter a Launch Time Offset value (range 0.0 to 1000.0 usec), store the value in the base radio, and initiate a simulcast test pattern. See Base Radio Service Help Service Screens Alignment Screens in the CSS Online Help for the alignment procedures. 5.4 ASTRO/Analog Simulcast Alignment (Conventional Operation) In an ASTRO 25 simulcast subsystem, all station transmitters are synchronized to a 1 pulse per second (1PPS) signal from a Global Navigation Satellite System (GNSS) receiver. The 1PPS signal provides a common time reference for each of the transmitters. The ASTRO 25 signaling information arriving at the station transmitter includes timestamps that specify the transmit offset delay for the voice and data transmissions. The ASTRO/Analog Alignment screen allows adjustment of the overlap coverage areas, and to specify a launch time offset value, with a 0.1 s resolution. This value is added to the arriving launch time value to provide an adjusted launch time. The specified ASTRO 25 simulcast transmit offset delay value applies only to ASTRO 25 simulcast subsystems and is considered optional. The default offset value is 0 (zero), causing no adjustment to the launch time specified by the arriving timestamp value. For Analog Simulcast, the Transmit Offset Delay merely delays the Analog Simulcast Audio to provide the adjustment in the overlap coverage areas. See Base Radio Service Help Service Screens Alignment Screens in the CSS Online Help for the alignment procedures. 5.5 Carrier Squelch Alignment A Carrier Squelch (CSQ) Alignment is typically performed at an RF level which corresponds to 12 dB SINAD, or an RF level which corresponds to 20 dB quieting, or any other RF level selected. The CSQ Alignment screen facilitates the measurement of 12 dB SINAD for the base radio under testing by allowing the Rx Qualifiers to be set to Open. When the Rx Qualifiers are set to Open, receive audio is gated to the WL2 wireline port or to the speaker, regardless of the RF input level. The preferred SINAD measurement port is the WL2 wireline port; however, the speaker can also be used. 159 MN003286A01-H Chapter 5: GTR 8000 Base Radio Optimization When measuring SINAD, the pre-emphasis and high pass filters are set as they would be for analog voice operation. Because the channel characteristics are different, this procedure allows for CSQ Alignment and is done for both 12.5 kHz and 25 kHz channel bandwidth. If the station is configured for only one channel bandwidth, there is no need to perform a CSQ Alignment for the other bandwidth. See Base Radio Service Help Service Screens Alignment Screens in the CSS Online Help for the alignment procedures. 5.6 Tx Wireline Alignment Tx Wireline Alignment is used to set the levels to result in 60% system deviation for both Wireline Level Line 1(WL1) and Wireline Level Line 3 (WL3) and for setting the Wireline Squelch levels. See Base Radio Service Help Service Screens Alignment Screens in the CSS Online Help for the alignment procedures. 5.7 Rx Wireline Alignment Rx Wireline Alignment is used only for a base radio that processes analog receive audio and is connected with a 2- or 4-wire link to a console or a comparator in an analog only topology or an ASTRO 25 Analog/Mixed mode topology. See Base Radio Service Help Service Screens Alignment Screens in the CSS Online Help for the alignment procedures. The Metering Screen displays current values for power supply and transmitter metering points on multi-

site base radios, site repeater base radios, HPD base radios, and digital conventional base radios. See Base Radio Service Help Service Screens Metering Screen in the CSS Online Help for the procedures for testing the transmitter. 5.8 Transmitter Testing 5.9 Tuning a Preselector The optional VHF or UHF preselector assembly is mounted on the back of a base radio. The preselector assembly is a 3-pole (UHF) or a 5-pole (VHF) bandpass filter equipped with tuning slugs to adjust the passband corresponding to the operating frequencies of the base radio. If the preselector assembly is replaced in the field, or if the base radio operating frequencies are modified, the preselector must be field tuned. IMPORTANT: Tuning for best SINAD or Bit Error Rate (BER) response DOES NOT result in optimum tuning of the preselector assembly. Use this field tuning procedure to obtain optimum preselector performance. The following test equipment is required to properly tune the preselector assembly:

RF Signal Generator - Aeroflex 3900 Series Service Monitor (or equivalent) Dip/peak Monitor - HP435B Powermeter (or equivalent) with an HP8484A sensitive power head, Boonton Model 92E with BNC input, or Aeroflex 3900 Series Service Monitor using the spectrum analyzer function 160 MN003286A01-H Chapter 5: GTR 8000 Base Radio Optimization Torque driver capable of delivering 12 in-lb of torque and 10 mm deep well socket Tuning probe - Motorola Solutions Part No. 3082059X01, p/o TRN4083A tuning kit Flat-blade screwdriver NOTICE: An R2600 Communications Analyzer can both generate and measure simultaneously. A service monitor may be used for either the generator or the monitor function, but not both simultaneously.

DIP. Duplexer modules shipped with base radios are tuned at the factory. If a duplexer must be replaced in the field, the unit must be installed and tuned specifically to the transmit and receive frequency pair for the particular base radio. 5.10 Tuning a Duplexer 5.10.1 Field Tuning Overview NOTICE: These tuning procedures are valid for channels with a bandwidth of 200 kHz or less. If bandwidth is more than 200 kHz, the duplexer must be tuned by the Motorola Solutions Support Center (SSC). The duplexer module is composed of three low-pass/high-notch cavities and three high-pass/low-notch cavities. Each set of three cavities provides bandpass filtering for either the transmit RF signal or the receive RF signal. In general, the duplexer must be tuned so that the transmit cavity set passes the transmit signal and rejects the receive signal; concurrently, the receive cavity set must be tuned to pass the receive signal and reject the transmit signal. Tuning is performed by injecting RF signals and making tuning adjustments (using the tuning rods and trimmer screws) while monitoring for maximum or minimum readings on the RF millivoltmeter. Field tuning the duplexer module requires the following general adjustments:

Tune high-pass/low-notch cavities for maximum pass and reject response Tune low-pass/high-notch cavities for maximum pass and reject response Check high-pass/low-notch and low-pass/high-notch cavities for insertion loss Check high-pass/low-notch and low-pass/high-notch cavities for isolation 5.10.2 Required Test Equipment Tuning of the duplexer module requires the following test equipment:

The duplexers are pre-tuned to operate over the entire sub-band. 5.10.4 Tuning a VHF Duplexer The following procedures are most easily performed with the duplexer module removed from the rack or cabinet. Know the transmit and receive frequencies for the particular base radio before beginning. If the duplexer module is tuned according to instructions and does not meet specifications for return loss, insertion loss, and/or isolation, the duplexer must be returned to the Motorola Solutions Support Center (SSC) for repair. 5.10.4.1 VHF Duplexer Tuning Setup Perform the tasks in Setting Up for VHF Duplexer Tuning on page 168 before tuning the VHF duplexer module.

Procedure:

1 Connect to the base radio in Configuration/Service Software (CSS) through an Ethernet connection. See Connecting Through an Ethernet Port Link on page 141. 2 From the menu, select Service Metering Screens. The Metering Screen window opens on the Power Supply tab. Figure 79: Metering Screen Window 5.11.3 Verifying Receiver Performance for FDMA Operation When and where to use:

Use this procedure to verify receiver performance by measuring the Bit Error Rate (BER) and Received Signal Strength Indication (RSSI) for digital operation. Procedure:

1 Make the following connections to the base radio:

a Disconnect the BNC antenna cable (or N connector if preselector is present) from the receive antenna Port. 2 Set up the service monitor:

b Connect the service monitor GEN port to the base radio Antenna Port. a Set modulation to Project 25 (C4FM) with a Standard 1011 test pattern. b Set the service analyzer to generate at the receive frequency. c Set the RF level an initial value of -47 dBm. 186 MN003286A01-H Chapter 5: GTR 8000 Base Radio Optimization 3 Connect to the transceiver module in Configuration/Service Software (CSS) through an Ethernet connection. See Connecting Through an Ethernet Port Link on page 141. 4 From the menu, select Service Test And Measurement Screen. 5 Select the ASTRO BER RSSI Report tab. 6 If the base radio is not in service mode perform the following, otherwise go to step 7 a Click Change to Service Mode. b At the confirmation screen, click OK. The base radio halts activity in the current mode and switches operation to the requested mode. c Re-open the Test And Measurement Screen as described in step 4. 7 Set up the test in CSS:

a In the Pattern Type field, select 1011 Hz (FDMA). b In the Sampling Period (sec) list box, enter the number of required seconds. The time specifies the window over which the BER is calculated. c For BER measurement, in the Rx Branch for BER Test field, select the receive branch. The available selections for Rx Branch for BER Test are dependent on the set Pattern Type. 8 Measure the BER and RSSI:

a Click Start BER Measurement or Start RSSI Measurement. The Test And Measurement Screen dialog box displays the following results:

BER results in percentage RSSI results expressed in dBm. NOTICE: With the initial setting of the service monitor set for a carrier level of -47 dBm, you should expect a BER of 0.0 % and an RSSI level between -49 dBm and -45 dBm. Compensate for the loss of the cable connecting the service monitor to the base radio. NOTICE: If the receiver is inhibited, RSSI displays a meaningless value. b To create a log file for the BER and RSSI measurement, click Start Log. The Log Save As window appears. c Change the RF level and read the BER and RSSI again at the level appropriate for the base radio. The value should be less than 5%. See GTR 8000 Base Radio Specifications on page 40 for the appropriate value. d Key the transmitter in the base radio and readjust the generator output level until 5% BER is indicated on the service monitor. Record this level. Less than 1 dB of degradation should occur due to the transmitters being keyed. e Dekey the transmitter. f Click Stop BER Measurement or Stop RSSI Measurement to stop the test. 9 If Rx B is used as a backup and the site is not TDMA:

a Disconnect the test cable from the generator to Rx A at the base radio and connect it to Rx B. 187 MN003286A01-H Chapter 5: GTR 8000 Base Radio Optimization b Increase the generate level to -47 dBm. c Wait for Branch A to fail. Alarms may be generated during testing. 1 This can take up to two (2) minutes. 2 CSS Channel tab Time to Failure (sec) field controls the time to fail. d Repeat step 8. 10 If no further testing is needed, place the base radio into Normal Mode, as follows:

a Click Change to Normal Mode. b At the confirmation screen, click OK. The base radio halts activity in the current mode and switches operation to the requested mode. 11 Remove and restore the following connections to the base radio:

a Remove the service monitor GEN port connection from the base radio Antenna Port. b Restore the antenna connection to the Receive Antenna Port. 5.11.4 Verifying Receiver Performance in TTA Operation This procedure explains how to verify receiver performance in a system where a Tower Top Amplifier

(TTA) is present. Consult with any documentation that is specific to your system for the value of TTA Reserve Gain. If no information is available, use the following guidelines:

For most situations, the TTA Reserve Gain should be in the 5 dB to 10 dB range. In the absence of guidance specific to your system, 7.5 dB is a useable value for TTA Reserve Gain. NOTICE: This procedure for TTA testing is valid only for FDMA operation. An entirely different procedure for TTA testing is required for TDMA operation. Contact your system administrator for guidance, then contact your Motorola Solutions representative for assistance. The Receive path attenuators must be configured before performing this part of the procedure. The Rx path to the Rx antenna on the tower must be complete. When and where to use:

Use this procedure to verify receiver performance in a system where a Tower Top Amplifier (TTA) is present. Procedure:

1 Perform test setup:

a Configure the analyzer to generate an STD1011 pattern. b Connect the Analyzer Gen port (3900) or the RF Generator Out port (S412E) to the TTA Test Port using a TNC-m (3900) or N-m (S412E) to BNC-m test cable with known loss. Record the cable loss value on the T tab, Test Cable #4. c Configure the TTA so that the Antenna port is terminated in a 50 load. If the TTA controller has a time out feature for the termination, make sure you periodically reset the TTA termination as needed. 2 Connect to the transceiver module in Configuration/Service Software (CSS) through an Ethernet connection. See Connecting Through an Ethernet Port Link on page 141. 3 If the base radio is not in service mode perform the following, otherwise go to the next step. 188 MN003286A01-H Chapter 5: GTR 8000 Base Radio Optimization a From the CSS menu, select Service Test And Measurement Screen. b Click Change to Service Mode. c At the confirmation screen, click OK. The base radio halts activity in the current mode and switches operation to the requested mode. d Re-open the Test And Measurement Screen. 4 Initiate TTA testing:

a On the Test And Measurement Screen, select the ASTRO BER RSSI Report tab. b In the Pattern Type field, select Project 25. c In the Sampling Period (sec) list box, enter 1 for the required seconds. d Set the Analyzer Generate Frequency equal to the Base Radio Rx Frequency. 5 Test the Rx Noise Level with the TTA terminated:

a Turn the analyzer generator OFF. b In CSS, click Start RSSI Measurement. c Record the RSSI Value in the RSSI Level Terminated field of the FDMA Chan sheet. This Rx Noise Level is a relative value and used for future comparisons. 6 Test the Rx RSSI Test Port Reference Level with the TTA terminated:

a Turn the analyzer generator ON. b Establish an Analyzer Generate RF Level that produces an RSSI Level of -90.0 dBm. c Record the Analyzer Generate RF Level in the Gen Level Reference field of the FDMA Chan sheet. The sheet calculates the Actual Reference Level. d In CSS, click Stop RSSI Measurement. The Actual Reference Level is a relative value used for future comparisons to assist in troubleshooting. This test establishes a known reference that is about 30 dB above the typical noise floor, which minimizes the contribution of noise to the measurement and is a better indicator of the gain through the receive system. Testing at the sensitivity level is a function of the carrier to noise ratio. Noise has a much bigger impact when testing at the sensitivity level. The goal of this test is to give you the information to determine if you have a gain issue or a noise issue when troubleshooting a receive problem. 7 Test the Rx Sensitivity with the TTA terminated:

a In CSS, click Start BER Measurement. b Adjust the Analyzer Generate RF Level for a 5% 0.25% BER. c Record the Analyzer Generate RF Level in the Gen Level Terminated field of the FDMA Chan sheet. d In CSS, click Stop BER Measurement. e Click Start RSSI Measurement. f Record the RSSI (dBm) value in the RSSI Sensitivity field of the results sheet. 189 MN003286A01-H Chapter 5: GTR 8000 Base Radio Optimization g Click Stop RSSI Measurement. The Test Result Sheet calculates the Actual Sensitivity Term using Sensitivity Terminated Test Cable Loss - TTA Test Port Cable Loss - TTA Test Port Coupling Loss. This result is the reference used to determine site degradation or de-sense in the following tests. 8 Test Rx De-sense for TTA Normal without other transmitters keyed. The degradation is < 2 dB

@ 700/800/900 MHz, < 6 dB @ 450 MHz, or < 10 dB @ 150 MHz. CAUTION: This test and the following Rx De-sense TTA Normal with Transmitters Keyed test cannot be performed accurately if the channel is in use within the coverage area of the site (for example, a legacy system waiting for cutover). a Configure the TTA so that the antenna port is connected to the antenna (normal operation). b In CSS, click Start BER Measurement. c If needed, readjust the Analyzer Generate RF Level for 5% 0.25% BER. Watch the CSS BER for about 1 minute. d Record the Analyzer Generate RF Level in the Gen Lvl Desense no Tx field of the result sheet. The difference between this generator RF level and the level recorded in the Rx Sensitivity with the TTA Terminated test is the site degradation/de-sense. NOTICE: If the BER reading is not stable, there is an external interference or a variable noise floor. Make a note on the Test Result Sheet that Channel X BER went to Y% while performing this test. The worksheet calculates the Degradation no Tx value. The degradation should be less than specified at the beginning of this step. If the degradation is higher than recommended, consult with your system administrator to determine what the impact could have on talk-in coverage. The Gen Lvl Desense no Tx level from this test becomes the benchmark for future PM checks. 9 Test Rx De-sense for TTA Normal with transmitters keyed. The degradation is < 2 dB @

700/800/900 MHz, < 6 dB @ 450 MHz, or < 10 dB @ 150 MHz. This test is optional for 700/800/900 MHz. CAUTION: This test cannot be performed if the RF channel under test OR any of the RF channels being keyed up are in use with an operating system in the same coverage area. a Key up the transmitters at the site. WARNING: Verify that you have removed the power sensor from the Tx path before keying up multiple transmitters. b If needed, readjust the Analyzer Generate RF Level for 5% 0.25% BER. c Record the Analyzer Generate RF Level in the Gen Lvl Desense w/Tx field of the FDMA Chan sheet. d De-key the transmitters at the site. e In CSS, click Stop RSSI Measurement. The result sheet calculates the Degradation with Tx value. If the degradation is higher than recommended, consult with the System Engineer to determine what the impact could have on talk-in coverage. 10 Test the Rx Noise Level with the TTA normal. This test establishes the noise floor of the receive system:

The Aeroflex 3900 series High Performance Data (HPD) service monitor has two forms of power measurement:

Broadband is similar to the working of an in-line wattmeter. In-band is performed after the RF signal is down converted to baseband by a Digital Signal Processor (DSP). If the HPD service monitor runs continuously, it requires periodic calibration. Re-calibration is required only if the User Calibration Threshold is exceeded. The service monitor displays a flag at the bottom indicating to re-calibrate to maintain the accuracy indicated in the User Calibration Threshold. For an HPD signal, only the in-band power meter is available. The in-band power measurement accuracy without a user calibration is 1 dB. User calibration improves the accuracy at a specific 200 MN003286A01-H Chapter 5: GTR 8000 Base Radio Optimization frequency, bandwidth, and temperature by using the broadband power meter to correct the in-band power measurement. This correction occurs when an in-band user calibration is performed. Procedure:

1 Press the UTILS button on the service monitor twice. NOTICE: Wait for approximately 1 second or more before pressing the UTILS button the second time. The Utility Menu screen appears. 2 From the menu, select User Calibration. The User Calibration screen appears. 3 Click Run User Calibration in the upper right corner of the User Calibration screen. NOTICE: The default user calibration setting is 1.0 dB. This setting means that a user re-

calibration is not indicated on the HPD service monitor until the in-band power measurement has a potential of 1.0 dB error in the measurement (same as the basic in-

band power meter accuracy). For HPD, a 0.5 dB value or lower is more appropriate. This value may require more frequent re-calibrations, but it provides better performance. A User Calibration message box appears instructing you to remove all connectors from the ports. 4 Remove all connectors from the ports. Click Continue. A progress bar appears showing the progress of the calibration process. The calibration completes in approximately 2 min. NOTICE: Failure to remove all connectors and cables from the ports causes an inaccurate user calibration. Any connectors present causes a variation on the impedance seen by the instrument during calibration. 5.12.3 Measuring HPD Base Radio Tx Power, Frequency Accuracy, and Tx EVM Procedure:

Excessive dust drawn across and into the device circuit modules by the cooling fans can adversely affect heat dissipation and circuit operation. In such installation, be sure to clean or replace external filtering devices periodically. If dust has accumulated on the fan grills, cleaning the fan grills is recommended. When cleaning, take care to prevent dust from being pulled into the modules. Use a damp cloth to wipe the front of the fan grills. When removing the power supply, turn off the unit before proceeding. 6.2 Aligning the Internal Frequency Reference Oscillator NOTICE: The base radio must be turned on for at least one week before the internal frequency reference oscillator is aligned. See Base Radio Service Help Service Screens Alignment Screens in the CSS Online Help for the alignment procedures. 209 MN003286A01-H Chapter 7: GTR 8000 Base Radio Operation Chapter 7 GTR 8000 Base Radio Operation This chapter details tasks performed once the GTR 8000 Base Radio is installed and operational on your system. 7.1 Base Radio Operational States for Trunked Simulcast GTR 8000 Base Radio modules can be in any one of the following four operational states:

Standby Idle Assigned Isolated Standby Idle Assigned Isolated 210 During initialization, the base radio powers up into the standby state and waits for a status packet from the comparator. When initial contact with the comparator has been made, the base radio enters idle mode. The base radio sends a status message back to the comparator indicating that it is ready for the assignment. After a base radio has been assigned, it can begin to handle inbound/outbound traffic. In the case where the base radio fails to receive status packets from the comparator, the base radio enters isolated mode and dekeys. This isolated mode is reported in the Unified Event Manager (UEM). If the base radio becomes operational again, and receives the status packets from the comparator, it again replies with a channel status message. The base radio returns to the idle state and is ready for an assignment from the comparator. Adjacent Site Search Holdoff For IP simulcast subsystems with 16 to 32 subsite capacity and geographically redundant prime sites with 1 to 32 subsite capacity, the Transport Network requires longer than 1 second to recover following a failure. To compensate for the subscriber unit scatter, the subscriber units are required to remain on the site for a longer duration following a control channel loss. A message is used to instruct the subscriber units to remain on the site for 10 seconds following the loss of a control channel. The base radio automatically transmits this message upon loss of packets from the prime site. 7.2 Base Radio Operational States for Trunked Repeater and HPD A GTR 8000 Base Radio can be in one of four operational states:

During initialization, the base radio powers up into the standby state and waits for a status packet from the site controller. After initial contact with the site controller has been made, the base radio enters idle mode and sends a status message back to the site controller indicating that it is ready for assignment. MN003286A01-H Chapter 7: GTR 8000 Base Radio Operation The site controller responds with a channel grant message, and the base radio enables for service. If the base radio has a greater home channel preference setting than other base radios at the site, then the zone controller assigns the base radio as the home channel at the site. After a base radio has been assigned, it can begin to handle inbound/outbound traffic. In the case where the base radio fails to receive a number of consecutive status packets from the site controller, the base radio enters isolated mode and dekeys. This isolated mode is reported in the Unified Event Manager. If the base radio becomes operational again and receives status packets from the site controller, it replies with a channel status message. The site controller may then respond with a channel grant, and the base radio becomes enabled for service again. 7.3 Base Radio Operational States for Conventional A GTR 8000 Base Radio can be in one of two operational states:

Standby/Receiving Transmit During initialization, the base radio powers up into the standby/receiving state and is enabled for service. The base radio listens for any received transmissions. After the base radio has received a transmission, it can then key-up and transmit. 7.3.1 Packet Data interactions with Multiple NACs If a base radio supports multiple NACs, such as when using the community base radio feature (F7F/

F7E), in addition to a default NAC, inbound data can be received on any incoming NAC and is forwarded to its destination. Outbound data is only transmitted to the default NAC. Outbound data cannot be routed to a selected NAC, it is always sent on the default NAC. Repeated data is only transmitted on the default NAC and does not follow the inbound NAC when community repeater (F7F) is being used. 7.3.2 Supplementary Signaling interactions with Multiple NACs If a base radio supports multiple NACs, such as when using the community base radio feature (F7F/

F7E), in addition to a default NAC, inbound supplementary signaling can be received on any incoming NAC and is forwarded to its destination. If using F7F/F7E, the same that voice would be transmitted, the outbound supplementary signaling is transmitted on either the default NAC or the currently selected NAC. Outbound supplementary signaling cannot be routed to a selected NAC, it is always sent using either the default NAC or the same NAC that voice would be transmitted on according to F7F/F7E functionality. 211 MN003286A01-H Chapter 7: GTR 8000 Base Radio Operation 7.4 Illegal Carrier Determination Feature (Trunked) The Illegal Carrier Determination feature allows the device channels to continue operating with system-

configurable levels of channel interference. In an ASTRO 25 system, the device uses Received Signal Strength Indicator (RSSI), an RF Threshold Value, and the Malfunction Timer Value to implement this feature. Table 48: Illegal Carrier Determination If the channel receives a... and is assigned:

and is not assigned:

Valid Network Access Code (NAC) The device does not change since the carrier is considered valid. If the RF Threshold Value is ex-

ceeded, the device enters the Ille-

gal Carrier state and generates an Illegal Carrier message to Unified Event Manager (UEM). Invalid Network Access Code

(NAC) OR Carrier activity without NAC If the RF Threshold Value level is exceeded, the Malfunction Timer is acti-

vated. After the timer expires, the base radio enters the Illegal Carrier state and generates an Illegal Carrier message to UEM. While in the ille-

gal carrier state, calls are not assigned to this channel. If the illegal carrier disappears or drops below the RF Threshold Value for 12.5% of the time period defined by the Malfunction Timer Value (or 10 seconds, whichever is greater), an event is sent to UEM clearing the illegal carrier state, the base radio exits the illegal carrier state and the channel is again included in the available channel resource pool for call assignment If the illegal carrier disappears or drops below the RF Threshold Value for 12.5%, but not less than 10 seconds of the time period defined by the Malfunction Timer Value, an event is sent to UEM. 7.5 RF Channel Interference Determination Feature (Conventional) The RF Channel Interference Determination Feature allows radio channels to detect RF interference and log it to the station log. RF Channel Interference is declared when the Carrier Squelch level is exceeded and none of the receive qualifiers are met. Receive qualifiers are the programmed Private Line (PL), Digital Private Line (DPL), or receive Network Access Code (NAC) for the currently active channel. 212 MN003286A01-H GTR 8000 Base Radio Troubleshooting Chapter 8 GTR 8000 Base Radio Troubleshooting GTR 8000 Base Radio troubleshooting requires an understanding of hardware-based and software-

based diagnostics, as well as testing tools. Support is available from Motorola Solutions to assist with all steps in the troubleshooting process. This chapter provides fault management and troubleshooting information relating to GTR 8000 Base Radio. 8.1 GTR 8000 Base Radio General Troubleshooting Table 49: GTR 8000 Base Radio General Troubleshooting Problem General connectivity problems Troubleshooting 1 If you have access to the equipment, check the LEDs to verify that each piece of equipment is connected and operational. See GTR 8000 Base Radio LEDs on page 265. 2 In Configuration/Service Software (CSS), check the condition of the base radio and all associated devices and links. 3 Verify the base radio configuration through CSS. Verify that the IP ad-

dress for the base radio is correct. In CSS, send a diagnostic com-

mand to enable the base radio. 4 For a Conventional Base Radio, Conventional Receiver, Site Repeat-

er (if present in a Tsub), or an HPD Base Radio (if present in a Tsub), verify that the DNS Hostname is correct. If the DNS Hostname was in-

correct and then corrected, further corrections may be needed on the DNS server, UNC, and UEM. See the Troubleshooting chapter in the Authentication Services manual. 5 Verify that the physical cabling is firmly connected and in good condi-

tion. Check for any sharp bends or kinks in cabling. Test suspected cabling for noise, continuity, attenuation, and crosstalk. Replace the cabling if necessary. 6 Run ping, traceroute, pathping, and other network administration com-

mands to identify any link or intermediate devices (switch or routers) with high latency or connection problems. 7 If the connection fails to operate normally, send a restart command to the base radio through CSS. Consider cycling power to the base radio if necessary. 8 If it still fails to operate properly, create a backup of the current config-

uration, then reinstall the software and reconfigure the base radio. 9 Replace the base radio if necessary. 213 MN003286A01-H Chapter 8: GTR 8000 Base Radio Troubleshooting Problem Device does not pow-

er up Device is in a continu-

ous reset state Exciter Failure Analog (4-wire) Por-

tion of V.24 Hybrid Link Failure Troubleshooting 1 If you have access to the equipment, check the LEDs to determine which equipment is connected and operational. See GTR 8000 Base Radio LEDs on page 265. 2 In CSS, check the alarms for the base radio. 3 Check the power cabling and verify that the power source for the base radio is supplying the appropriate voltage. Try connecting the base ra-

dio to another power source or replace the power cabling if necessa-

ry. NOTICE: Check all power sources as there may be more than one. 4 Check for any physical damage to the modules and check whether the modules were properly grounded. 5 Replace any defective modules. Assure reference inputs are connected to the appropriate input. Verify that an antenna relay Enabled either in the UNC or CSS may have been disconnected. This disconnect causes the base radio to generate an exciter failure because the antenna relay is controlled and monitored through the exciter module. However, the exciter failure should be ignor-

ed until after the antenna relay failure is corrected. In a mixed mode configuration, with hybrid links, and when analog link monitor tone is enabled (Analog Link Idle Check is enabled in the CSS), the base radio detects a link failure when the analog link monitor tone and call activity are absent on the receive line (WL1). Disable Analog Idle Link Check in the CSS when the comparator type is ASTRO-TAC with DIGITAC or ASTRO-TAC with MLC 8000. When these failure conditions are met, the base radio:

1 Logs an occurrence of the failure in the local event log. This log is re-

trievable through the configuration interface. 2 If connected to centralized fault management equipment (optional), transmits an alarm indication to the fault manager to alert the system administrator of the failure. 3 A local visual indication is active due to this failure. Recovery of the link failure results in a similar set of actions to indicate that the failure event cleared. NOTICE: A failure of the transport line or a failure of the oppos-

ing host on the wireline link both appear to the base radio as a link failure. The base radio cannot distinguish between these two cases. V.24 Portion of Hybrid Link Fails In a mixed-mode configuration, with hybrid links, the base radio detects a V.24 link failure when packet activity is absent for a time on the outbound transmit line. When these failure conditions are met, the base radio:

1 Logs an occurrence of the failure in the local event log. This log is re-

trievable through the configuration interface. 214 MN003286A01-H Chapter 8: GTR 8000 Base Radio Troubleshooting Problem Troubleshooting Front Fan Malfunction In the event the fan assembly malfunctions, the base radio:

2 If connected to centralized fault management equipment (optional), transmits an alarm indication to the fault manager to alert the system administrator of the failure. 3 A local visual indication is active due to this failure. 4 Invokes a failure announcement for the 4-wire link because control signaling on the V.24 link drives activity on the 4-wire link. A 4-wire link cannot be used when the V.24 link is down. Recovery of the link failure results in a similar set of actions to indicate that the failure event cleared. NOTICE: A failure of the transport line or a failure of the oppos-

ing host on the wireline link both appear to the base radio as a link failure. The base radio cannot distinguish between these two cases. In the event the base radio detects a hardware issue with the transceiver option card, when used for analog and mixed mode operation, it:

1 Logs an occurrence of the failure in the local event log. This log is re-

trievable through the configuration interface. 2 If connected to centralized fault management equipment (optional), transmits an alarm indication to the fault manager to alert the system administrator of the failure. The alarm is associated with the base ra-

dio control module. 3 A local visual indication is active due to this failure. 1 Logs an occurrence of the failure in the local event log. This log is re-

trievable through the configuration interface. 2 If connected to centralized fault management equipment (optional), transmits an alarm indication of warning severity to the fault manag-

er to alert the system administrator of the failure. The alarm is associ-

ated with the base radio control module. 3 Provides a local visual indication associated with the failure. 4 If the base radio detects the maximum operable temperature has been exceeded, it transitions to a critical malfunction state, logs the state change, and generates a fault indication if connected to the UEM. The following conditions must be met to obtain a power consumption of less than or equal to 35 W:

DC source only card) Speaker turned OFF (if equipped with a transceiver option card) No activation of Aux Out Relays (if equipped with a transceiver option No 29 V AUX loads. For example, active draws by a site controller CSS configured for applications not requiring receiver diversity CSS Fan Holdover configured to short (length of time the fan stays ON after transmission) 215 Transceiver Option Card Hardware Mal-

function Power Consumption is greater than 35 W with power efficiency pack-

age MN003286A01-H Chapter 8: GTR 8000 Base Radio Troubleshooting Problem Troubleshooting Ambient temperature of 104 F (40 C) or less (single fan operation disabling one of the fans within the fan module. See Replacing the Fan Assembly on page 238 for instructions on how to disable the fan.) NOTICE: To validate the 35 W standby power consumption specification, wait for the main fans to turn off after the transmitter dekeys. The fan holdover configuration in the CSS controls the turn-off delay of the main fans. Single-fan operation requires the Tx Power Out in the CSS to be limit-

ed to 50 W. Transceiver, power amplifier,power supply, fan, and optional TCXO transceiver option card are all power efficiency package versions If the device module has been replaced and serial port access is not available to configure the IP address, the device may have the account locked out or the backplane slot has passwords enabled. Connect to the front-panel local Ethernet service port using a fixed IP address and per-

form the password reset. See Connecting Through an Ethernet Port Link on page 141 and Setting the Local Password Configuration in CSS on page 150. Unable to perform a password reset 8.2 GTR 8000 Base Radio Troubleshooting Tools Several tools are available for viewing and monitoring equipment and troubleshooting suspecting problems:

LEDs Unified Event Manager (UEM) to monitor links and components Unified Network Configurator (UNC) Configuration/Service Software (CSS) MOSCAD Network Fault Management (NFM) NOTICE: The Unified Event Manager (UEM) can be established as a more centralized fault management solution replacing the MOSCAD GMC. See the Unified Event Manger and the UEM/GMC Transition Setup Guide for details. In addition, see Quick Connect RF Coaxial Adapters for GTR 8000 Base Radio Support on page 122 for testing system performance. 8.2.1 Links and Components Monitoring in Unified Event Manager The Unified Event Manager (UEM) monitors critical links and components in the system. Monitoring may take place remotely from a central operations center. Two types of monitoring include:

Real-time monitoring of UEM Topology Maps, which alert faults as they occur. Evaluation of UEM Active Alarms Window on a regularly scheduled basis. 216 MN003286A01-H Chapter 8: GTR 8000 Base Radio Troubleshooting 8.2.1.1 Unified Event Manager Active Alarm Window Analyzation The Unified Event Manager (UEM) Active Alarms Window is useful for troubleshooting because it captures alarms that may occur intermittently or during off-hours. For example, you can review the Active Alarms Window to correlate reported loss of service with patterns of critical alarms for links and equipment. When analyzing the Active Alarms Window, look for the following patterns:

Failures sent with time stamps on or about the same time Failures from related equipment:

- Cards in the same device

- Equipment part of the same subsystem Many devices send out events that report both critical and non-critical events. Learn to distinguish between critical and non-critical events. See the Unified Event Manager manual or UEM Online Help for further details. 8.2.1.2 Diagnostic Options in Unified Event Manager This table summarizes the base radio diagnostic options in the Unified Event Manager (UEM). Table 50: Base Radio Diagnostic Options in UEM Description Option Restart Service Enabled Requests that the base radio performs a reset. Requests that the base radio enters service mode, allowing a tech-

nician to make alignment adjustments and run other tests while the base radio is offline. Requests that the base radio enters the enabled mode and handle traffic. 8.2.2 MOSCAD Network Fault Management If MOSCAD Network Fault Management (NFM) equipment is supported at the site, additional status, and alarm information for a device can be viewed through the MOSCAD NFM. 217 MN003286A01-H Chapter 8: GTR 8000 Base Radio Troubleshooting Figure 90: MOSCAD Network Fault Management Example When an alarm condition occurs, the alarm device for one of the modules begins to flash red. Selecting the LED box opens an alarm pop-up window indicating details of the alarm. To view the status of all alarms for a particular module within the device, select the alarm LED box corresponding to the particular module. Alarms can be acknowledged by pressing the Acknowledge button on the screen. See the MOSCAD Network Fault Management Feature Guide for details. NOTICE: The Unified Event Manager (UEM) can be established as a more centralized fault management solution replacing the MOSCAD GMC. See the Unified Event Manger manual and the UEM/GMC Transition Setup Guide for details. 8.2.3 Device Troubleshooting in Unified Network Configurator Use the Unified Network Configurator (UNC) to verify configuration data during system commissioning and later when you maintain or expand the system. Use UNC to do the following to the device:

Verify configuration Correct configuration errors See the Unified Network Configurator manual for further details. 8.2.4 GTR 8000 Base Radio Troubleshooting in Configuration/Service Software The GTR 8000 Base Radio can be locally or remotely configured or serviced through Configuration/

Service Software (CSS). CSS provides access to alarms, status information, and configuration settings for the base radio. Use CSS for the following tasks which may be useful when troubleshooting the base radio. See the CSS Online Help for specific details and instructions when performing these tasks. Enable and disable channels and services View and save a log of alarms 218 MN003286A01-H Chapter 8: GTR 8000 Base Radio Troubleshooting Verify the configuration Gather troubleshooting information that can be escalated to Motorola Solutions for evaluation 8.2.4.1 Internal Diagnostic Test Alarm Log The base radio has been designed with internal diagnostic tests that occur on power up and reset. Diagnostic tests are available for the control module and power supply. If a problem occurs during operation, it is reported as an alarm. All alarms are stored in the Alarm Log, accessible with Configuration/Service Software (CSS). The alarm log contains the name of the diagnostic test that failed and the time since the last power up. 8.2.4.2 Local Password and SNMPv3 Passphrase Troubleshooting The password reset mechanism in the Configuration/Service Software (CSS) application can be enabled/disabled. See Secure Remote Access Configuration > Device Security Configuration -

MSUs attempt to operate on another channel at the site. If another channel is not available, the MSUs attempt to register at another site. For HPD and repeater site operation, the base radio receives external frequency reference and network time synchronization from the active site controller over the Ethernet link. If there is a loss of the external time and frequency reference source, the base radio continues to maintain its own time and frequency stability to continue operations for a specified amount of time without degradation. Afterwards, operation continues with minimal degradation. 8.4 Conventional Site Controller Failure - Impact on GTR 8000 Base Radio for Conventional Operation For IP interfaced conventional base radios, a conventional site controller provides support for dispatch consoles to manage and control the conventional base radios in K core and M core type systems, the conventional site controller only provides support for the console to manage and control the conventional base radios when the primary (and optional secondary) zone controllers are not reachable. If the conventional site controller fails when it is the active call controller in either type system, the dispatch console loses its ability to manage and control the channel resources. However, subscriber radios may still be able to maintain communications using repeat functionality of the base radios or when the base radios are connected to a comparator. The comparators repeat functionality enables wide area repeat for subscribers. 8.5 Motorola Solutions Support Center Motorola Solutions Support Center (SSC) can help technicians and engineers resolve system problems, and ensure that warranty requirements are met.

If you must replace a FRU or part, it is essential to obtain the precise FRU Kit Number or part number, and to review the replacement procedures provided, including all safety precautions and system impact information. This chapter lists the FRUs and Field Replaceable Entities (FREs), and includes replacement procedures applicable to GTR 8000 Base Radio. 9.1 Field Replaceable Units (FRUs) and Parts When ordering Field Replaceable Units (FRUs), provide the FRU Kit Number. When ordering field replaceable parts, provide the part number. Contact Motorola Solutions Support Center (SSC) as needed for numbers not provided here (for cables internal to a GTR 8000 Base Radio, the part numbers are not listed in this documentation, but you can locate the part number on the cable before contacting Motorola Solutions SSC). See Motorola Solutions Support Center on page 220. WARNING: To guard against personal injury and/or damage to equipment, place the trunked base radio in Service Mode when performing service. The GTR 8000 Base Radio periodically keys up to pseudo train its linear transmitter autonomously when not assigned by the zone controller. Tx Inhibiting the base radio also prevents the transmitter from keying. Remember to place the base radio back in Normal Mode when service is complete.

The GTR 8000 Base Radio is a normal duplexed repeater while the GPW 8000 Receiver monitors the TX frequency. The other channel is for talk-

around (transmit and receive). This option is sometimes called the triple relay option. A GPW 8000 Receiver is used to monitor the second frequency. A standalone T7039A GTR 8000 Base Radio is required for this option kit. One GPW 8000 Receiver must be ordered without this option. This option kit includes 3 RF (transmit/receive) antenna relays, control cables, RF cables, and mounting hardware. The base radio must be ordered with the appropriate duplexer option. All option kit hardware and cables required are included in Table 85: T2-2R with Duplexer and Triple Relay Option Kit Parts List on page 305. NOTICE: The photos and illustrations in this section show the GPW 8000 Receiver with one chassis with one transceiver. A dual-slot chassis with two transceivers is available.
