Avaya Communication Manager controlled maintenance
ISDN-SGR (ISDN-PRI Signaling Group)
Maintenance of the Avaya G350 Media Gateway
141
June 2004
The operation of the entire ISDN-PRI signaling group depends on several other entities: the ISDN-PRI
signaling channel ports, the MG-DS1 Interface Media Module on which the D-channels reside and the
system link that is carried over the packet bus to the processor. When there are problems with the
ISDN-PRI signaling group, also investigate ISDN-LNK, MG-DS1, and SYS-LINK.
Error Log Entries and Test to Clear Values
Notes:
•
This switch sent a message to the far-end switch or terminal adapter, and the far-end did not
respond in the allotted time. Possible causes include link failure and congestion or outage at the
far-end. The Aux Data field contains Layer 3 protocol information used by internal counters.
If no other symptoms are present, no action is required. If Layer 3 communication is down, there
should be indications in the form of alarms and errors for link components. Check out other errors
against ISDN-SGR, ISDN-TRK, and other hardware components on the link.
There is no test to clear these errors. The error counter is decremented by 1 every 15 minutes.
