GTR 8000 Base Radio Description
This chapter provides a high-level description of the GTR 8000 Base Radio and the function it serves
in your system.
1.1
Introduction
Figure 1: GTR 8000 Base Radio
This manual provides information on the standalone GTR 8000 Base Radio and associated
applications. 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.

GTR 8000 Base Radio Components
Table 1: Base Radio Modules and Function
Base Radio Description
Power Supply 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.
Power Amplifier (PA) 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 related to the fan module.
Transceiver (XCVR) Provides the control, exciter, and receiver functions for
the base radio.
Transceiver Option Card An optional board that attaches to the control board of the
transceiver. Provides an internal 10 MHz frequency reference. For conventional base radio operation, it also provides the analog interfaces and WildCard I/Os. The transceiver option card is available in two categories:
OCXO (Oven Controlled Crystal Oscillator)
•
• TCXO (Temperature Compensated Crystal Oscillator)
NOTICE: The OCXO board when initially powered on takes a few minutes to reach its operational 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 condition 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.

1.4
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-E
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
Chapter
MN003286A01-E
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.

MN003286A01-E
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
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.

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-E
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.

Overview of a GTR 8000 Base Radio in a Trunked 3600 System
In a trunked 3600 system, the GTR 8000 Base Radio control channel runs at 3600 bps, and the voice
channels can be configured for analog or ASTRO® 25 voice operation.
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 (380–435 MHz)
• UHF R2 (435–524 MHz)
• VHF (136–174 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.

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
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.

®
MN003286A01-E
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 237 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.

License Auditing
License auditing for ASTRO®
License Manager to ensure that site licenses have been purchased and also to prevent the transfer of
site licenses across systems.
The License Manager performs the following functions:
• Monitors the number of site devices in use within the system.
• Audits the number of active licenses.
• Displays a noncompliance notification on the Unified Event Manager (UEM) when the number of
devices exceeds the licenses.
If a site license is not present, the following functions do not occur:
• Send or receive audio
25 G-series devices at M and L core systems can be enabled through the

• Vote audio
Implement site control functions; such as assigning channels or calls.
•
Any issues with an existing site license are sent to the UEM without system functionality being
restricted.

GTR 8000 Base Radio Theory of Operation
Chapter 2
GTR 8000 Base Radio Theory of
Operation
For an understanding of the GTR 8000 Base Radio components, review the modules that provide the
base radio functionality, the modules that provide RF distribution functionality (RFDS), and the
backplane that connects to other modules within the site.
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-E
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
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
base radio is loaded in the XCVRs control section. As the main
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-E
Chapter
2.1.1.2.1
2: GTR 8000 Base Radio Theory of Operation
Exciter
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.
2.1.1.2.2
Receiver
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 792–825 MHz, UHF R1 380–
435 MHz, UHF R2 435–524 MHz, or VHF 136–174 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
page 264 for information on the LEDs.

Transceiver Switch
The multifunction RESET switch on the front of the transceiver module is accessible through the dropdown door to the left of the fans. The RESET switch has two functions:

Transceiver Option Card Intercom Button
The intercom button on the front of the transceiver option card is accessible behind the fan module.
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
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.

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 153.

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 237 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.

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

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-E
Chapter
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
2: GTR 8000 Base Radio Theory of Operation
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

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.

Chapter 3: GTR 8000 Base Radio Installation
• Use strain relief when installing and positioning cables and cords to help ensure that no interruption
of service occurs.
Provide an appropriate amount of space around all components to allow for proper air flow, cooling,
•
and safe access to equipment.
• Locate the site racks and other equipment with enough spacing to allow access for service.
NOTICE: Proper spacing of equipment is essential for ease of maintenance and safety of
personnel. Spacing requirements have been established to meet the National Fire Protection
Associations (NFPA) code, and the American Society of Heating, Refrigerating, and Air
Conditioning Engineers (ASHRAE) standards. Adhere to any local regulations that apply to
the installation.
• Locate the system in an area free of dust, smoke, and electrostatic discharge (ESD).
See the Motorola Solutions Standards and Guidelines for Communication Sites manual for details
•
on these space requirements.
3.3.4
General Cabinet Bracing Recommendations
Use all supplied bracing hardware when installing a rack or cabinet, and secure all equipment within a
rack or cabinet.
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.
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:
1 Carefully mark the mounting holes with a pencil, as indicated on the appropriate cabinet or rack
footprint.
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.
88
MN003286A01-E

bolts with anchors.
3.3.6
3: GTR 8000 Base Radio Installation
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
standards.
IMPORTANT: System certification was completed using shielded cables. To prevent emission
problems, use only shielded cables. Do not substitute other cable types.
• 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.

on providing electrical service, power budgeting, selecting batteries, and other topics for supplying
power at the site.
89
MN003286A01-E
Chapter 3: GTR 8000 Base Radio Installation
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.
• 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 Resistance
#6 gauge 0.3951 /1000 ft
#4 gauge 0.2485 /1000 ft
#2 gauge 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 = [Ώ
See DC Power Connection Wire Gauge Calculations for Integrated Voice and Data on page 101 and
DC Power Connection Wire Gauge Calculations for HPD on page 102 for additional guidelines on the
cable sizing.
/1000 ft] x [total loop length (ft)] x [Ipeak (A)] + [connector(s) voltage drop(s)]
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.
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 threeprong 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.
