Faceplate LEDs
The faceplate LEDs provide status information using a color coded message format. Table 4 gives a
description of all faceplate LEDs for the T1 RCU when used with the Total Access 850 system.
For these LEDs...

Faceplate Bantam Jack
The faceplate bantam jack provides a means to monitor the network T1 connected to the rear of the
Total Access 850 chassis. The jacks accept standard 310-type bantam plugs. Figure 4 displays the bantam

This color light... Indicates that...
OFF there is no power to the system.
Solid GREEN the system is connected to an active power source.
OFF there are no active T1 alarms on the system.
ON there is an active T1 alarm (yellow, red, or blue alarm) on
the system.
AMBER the network T1 is in test mode (loopback).
Blinking RED there are errors on the network T1 (framing errors,
bipolar violations, or CRC errors).
Blinking GREEN there is transmit data detected on the V.35 port. This
LED blinks with data traffic.
Blinking GREEN there is received data detected on the V.35 port. This
LED blinks with data traffic.
OFF there is no active Ethernet link.
Solid GREEN there is a valid Ethernet link on the 10BaseT interface.
Blinking GREEN there is received or transmitted data detected on the
Ethernet interface. This LED blinks with data traffic.
