Troubleshooting

Information

This chapter describes troubleshooting features.

Troubleshooting Interfaces

The Telephony Modem provides two troubleshooting interfaces: the 
front panel LEDs and the telemetry block.

Front Panel LEDs

The front panel LEDs provide information about DOCSIS and tele-
phony status.

The LED patterns shown in this section are valid for the default firm-
ware version installed on the Telephony Modem. See the 

Troubleshoot-

ing Guide

 corresponding to the actual firmware installed for updated 

LED patterns.

Power-On Self Test Failure Pattern

When a Telephony Modem fails power-on self test (POST), it repeats 
the following sequence:

•

POWER LED on for 2 seconds; other LEDs off

•

All LEDs flash rapidly (10 times per second) for 10 seconds

A Telephony Modem repeatedly displaying this sequence is defective 
and should be replaced.
