Base Station/Repeater Operation: Description 3-1
Chapter 3 Base Station/Repeater Operation
3.1 Description
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 SCM.
3.1.1 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 in Figure 3-1. These LEDs indicate the status of the base station/repeater
during normal operation.
Figure 3-1 Front Bezel LEDs and Connectors
For further information on the states of these LEDs, refer to “Front Bezel LEDs” on page 2-28.
3.1.2 External Device Connections
Refer to Section 2.3: Electrical Connections for the position of the base station/repeater external
connectors and line cord, located on the back panel.
The connection to external devices on the back panel is the J7 Auxiliary System Connector. The
connector is a 25-pin connector used for connecting to an external device such as a trunking
controller, tone remote adaptor or phone patch. See Figure 2-10 for the location of the connector.
The connection to external devices on the front of the SCM is the BNC connector. The connector
allows the base station/repeater to be connected to a 5 MHz or 10 MHz external reference signal.
Figure 3-1 shows the location of the connectors on the front of the SCM and Figure 3-2 shows the
position of the BNC connector on the SCM.
