MG-DS1 (DS1 Interface Media Module)
Issue 1 June 2005 1617
1 FAIL The test failed. The MM710 interface Media Module detected a loss of
multiframe alarm (LMA). An out of frame condition occurred on the
MM710 interface Media Module. The MM710 interface Media Module will
transmit a remote multiframe alarm (RMA) to the remote MM710 endpoint
until the LMA is retired.
If the MM710 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. Check the physical connectivity of the MM710 packs and of the
cable.
3. Replace the local MM710 interface Media Module, and repeat the
test.
4. Contact T1 Network Service or a technician at the far-end switch to
diagnose the remote DS1 endpoint.
If the MM710 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. Check the physical connection of the MM710 interface Media
Module to the terminating device, and check the premise distribution
system (or the intra-premise wiring) for physical connection failures.
4. Replace the local MM710 interface Media Module and repeat the
test.
5. Contact the vendor of the line-side terminating device to diagnose
the equipment.
