MG-DS1 (DS1 Interface Media Module)
196 Maintenance of the Avaya G350 Media Gateway
June 2004
1 FAIL The test failed. The MG-DS1 interface Media Module detected a loss of
multiframe alarm (LMA). An out of frame condition occurred on the MG-
DS1 interface Media Module. The MG-DS1 interface Media Module will
transmit a remote multiframe alarm (RMA) to the remote MG-DS1
endpoint until the LMA is retired.
If the MG-DS1 connects to a T1 network facility or to another switch, do
the following:
1
Verify that both endpoints of the DS1 link are administered
using the same signaling mode, framing mode, and line
coding.
2
Contact T1 Network Service or a technician at the far-end
switch to diagnose the remote DS1 endpoint.
3
Check the physical connectivity of the MG-DS1 packs and
of the cable.
4
Replace the local MG-DS1 interface Media Module, and
repeat the test.
If the MG-DS1 connects to a line-side terminating device (for example, a
PRI terminal adapter), do the following:
1
Verify that the switch DS1 and the line-side terminating
device are administered using the same signaling mode,
framing mode, and line coding.
2
Investigate the maintenance status of the line-side
terminating device. Refer to the ’Line-Side Terminating
Device Operating Manual’ for information.
3
Contact the vendor of the line-side terminating device to
diagnose the equipment.
4
Check the physical connection of the MG-DS1 interface
Media Module to the terminating device, and check the
premise distribution system (or the intra-premise wiring)
for physical connection failures.
5
Replace the local MG-DS1 interface Media Module and
repeat the test.
