Base Radio Module Overview
The Motorola MTR3000 Base Station / Repeater (BR) provides a modular, flexible analog and digital station design
for today's communication systems and of the future. The stations are available for use in Analog Conventional,
Digital Conventional (MOTOTRBO), LTR Trunking, Passport Trunking, MOTOTRBO Capacity Plus Trunking, and
MOTOTRBO Connect Plus Trunking configurations.
The MTR3000 BR can either be configured as a stand-alone base station / repeater or as a base station / repeater
connected to a back-end network, as in the case of operating in IP Site Connect mode. As a base station /
repeater, it listens on one uplink frequency, and then re-transmits on a downlink frequency thus providing the RF
interface to the field subscribers. When configured for analog station operation, the BR is designed to operate with
most existing analog systems, therefore making a smooth migration to the MOTOTRBO system.
When configured for digital operation, the BR offers additional services. The digital BR operates in TDMA mode,
which essentially divides one channel into two virtual channels using time slots; therefore the user capacity is
doubled. The BR utilizes embedded signaling to inform the field radios of the busy/idle status of each channel
(time slot), the type of traffic, and even the source and destination information.
Note: When configured in Digital Mode, the BR can only be used as a repeater.
Note: At any given time, the BR either operates as a digital repeater or as an analog repeater.
The MTR3000 BR is divided into functional modules that separate the frequency band specific and transmitter
power specific circuits from other circuits and has separate modules for the control interface. These modules are
self contained functional blocks with module-specific alarms. This design facilitates the field replaceable unit
(FRU) concept of field repair to maximize system uptime.
Indicators and Connections
This section describes the LED indicators and connectors provided on the base station / repeater. The set of
LEDs indicate the operational status of the base station / repeater. There are two sets of connectors for devices
external to the base station / repeater:
• One set connects to external devices to enable full operation of the base station / repeater. These are
located at the back of the base station / repeater.
• Another set connects to external devices for servicing the base station / repeater. These are located on
the Station Control Module.
LED Indicators
A set of eight LEDs is located on the base station / repeater front bezel. The position of the eight LEDs on the
front bezel is shown below. These LEDs indicate the status of the base station / repeater during normal operation.
Front Bezel LEDs and Connectors
After booting up the base station / repeater, the six LEDs (Power/Status, TX Slot 1, TX Slot 2, RX Slot 1, RX Slot 2
and the Mode LEDs) flashes in unison. The general status and condition of the MTR3000 Base Station / Repeater
can be obtained by observing the eight LED indicators on the front bezel. The following tables show the LED
symbols and their meaning and identify the information conveyed via the LED indicators.
