cmgSyncSignalFault — Synchronization signal lost.
1. Check that provisioned clock-sync source has a good signal by 
issuing a Media Gateway Processor (MGP) Command Line 
Interface (CLI) command show sync timing 
Procedure for setting synchronization timing sources on T1/E1 MM 
or MM710:
1. Be sure that the T1/E1 MM has been added properly on the 
Avaya S8300 Media Server or Avaya S8700 Media Server, 
otherwise go to System Access Terminal (SAT) and enter a 
add DS1 command before going to the MGP CLI and entering 
set sync interface or set sync source command. 
Otherwise the MGP CLI will not allow these commands to be 
executed.
2. Go to the MGP’s CLI, and first specify the primary and 
secondary clock sources for synchronizing the T1/E1 span, 
using the set synch interface command. 
Note: You don't specify the internal clock source from the CLI - 
only the primary and secondary. The local clock is "built-in" and 
not provisionable.
3. Enter a set sync source command to set to the specific 
MM710 T1/E1 Media Module to be used as the active clock 
reference.
4. Verify whether or not these commands were executed by 
issuing a show sync timing command to ensure that the 
source is provisioned and active, or visually inspect the Yellow 
LED on the MM710 Media Module.
Note: When the Yellow LED is on 2.7 seconds and off 0.3 
seconds, this means the tone-clock synchronizer is in “active” 
mode, and an external synchronization source is being used as 
a synchronization reference. Setting the sync timing was 
successful.
When the Yellow LED is on 0.3 seconds and off 2.7 seconds, 
this means the tone-clock synchronizer is in “active” mode and 
the internal (on-board) clock is being used as a synchronization 
reference. Setting the sync timing was not successful.
