Configuring The Ethernet Lan Switch; Overview For A Gtr 8000 Base Radio In A High Performance Data (Hpd) Subsystem - Motorola ASTRO 25 GTR 8000 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 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 either 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 as 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)

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).
