Synchronization Status - Avaya G450 Manual

Setting synchronization
If the Avaya G450 Media Gateway includes a second MM710 media module, enter the following
additional command:
set sync interface secondary v3
set sync source secondary
If, for any reason, the primary MM710 media module cannot function as the clock
synchronization source, the system uses the MM710 media module located in slot 3 of the
Avaya G450 Media Gateway chassis as the clock synchronization source. If neither MM710
media module can function as the clock synchronization source, the system defaults to the local
clock running on the S8300 Server.
To disassociate an interface previously specified as the primary or secondary clock
synchronization source, enter clear sync interface primary or clear sync
interface secondary.
To enable or disable automatic failover and failback between designated primary and secondary
synchronization sources, enter set sync switching enable or set sync switching
disable.

Synchronization status

The yellow ACT LED on the front of the MM710 media module displays the synchronization
status of that module.
If the yellow ACT LED is solidly on or off, it has not been defined as a synchronization
●
source. If it is on, one or more channels is active. If it is an ISDN facility, the D-channel
counts as an active channel and causes the yellow ACT LED to be on.
When the MM710 is operating as a clock synchronization source, the yellow ACT LED
●
indicates that the MM710 is the clock synchronization source by flashing at three second
intervals, as follows:
The yellow ACT LED is on for 2.8 seconds and off for 200 milliseconds if the MM710
●
media module has been specified as a clock synchronization source and is receiving a
signal that meets the minimum requirements for the interface
The yellow ACT LED is on for 200 milliseconds and off for 2.8 seconds if the MM710
●
media module has been specified as a synchronization source and is not receiving a
signal, or is receiving a signal that does not meet the minimum requirements for the
interface
