Description / Recommendation
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 E1/T1 MM or
MM710:
1. Be sure that the E1/T1 MM has been added properly on the
Avaya™ S8300 Media Server or Avaya™ S8700 Media Server,
otherwise go to System Access Terminal (SAT) and issue a ADD
DS1 command before going to the MGP CLI and issuing a 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 E1/T1 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. Issue a set sync source command to set to the specific MM710
E1/T1 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.
5. If there is more than one MM710 Media Module, and they have
been set up as primary and secondary, this behavior could be on
the second and not the timing of the bus.
