Setting G700 Synchronization
If the AvayaTM G700 Media Gateway contains an AvayaTM MM710 Media Module (DS1), it is usually 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 AvayaTM S8300 Media Server, however, the usual 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:
- 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.
- 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.
- 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.
- At the prompt, type set syn sou pri.
- 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.
