Setting G700 Synchronization; Viewing G700 Sync Sources - Avaya G700 Maintenance Manual

5 G700 Component Maintenance:

Setting G700 Synchronization

If the Avaya TM G700 Media Gateway contains an Avaya
advisable to set the MM710 up as the primary synchronization source for the G700. In so doing, clock sync
signals from the Central Office (CO) are used by the MM710 to synchronize all operations of the G700. If
no DS1 is present, it is not necessary to set synchronization.
If Avaya MultiVantage™ Software 1.2 is running on an Avaya
SAT screens for "display sync" and "change sync" are not present. It becomes necessary to set clock
synchronization using the CLI interface with the Media Gateway Processor. Use the following procedure:
1 . Login at the Welcome to Media Gateway Server menu.
You are now logged-in at the Supervisor level on the Media Gateway Processor. The prompt
appears as MG-mmm-1(super)>, where mmm is the administered G700 Media Gateway number
in the network.
2 . Type configure to access the configuration prompt.
The prompt will change to indicate that you are in configuration mode. In the configuration mode,
you may use the set commands.
3 . At the prompt, type set sync interface primary <mmid>.
The MM710 Media Module is now configured as the primary clock synchronization source for
the G700 Media Gateway.
4 . At the prompt, type set syn sou pri.
5 . If the G700 Media Gateway contains a second MM710 Media Module, type set sync interface
secondary.
If, for any reason, the primary MM710 Media Module cannot function as the clock
synchronization source, the system defaults to the secondary MM710 Media Module for that
function. If neither MM710 Media Module can function as clock synchronization source, the
system defaults to the local clock running on the S8300 Media Server.
!
CAUTION:
Verify that the other end of the DS1 that you have selected as primary or secondary is not
syncing from you.

Viewing G700 Sync Sources

If you want to determine the locations of the clock synchronization sources, do the following:
1 . As in the procedure above, open a session in the Media Gateway Processor.
The command prompt should appear as MG-mmm-1(super)>, where mmm is the number by
which the G700 Media Gateway is registered in the network.
2 . Type show sync timing
This command displays the locations and status of the primary, secondary, and local clock
sources.
