1 FAIL The UDS1 interface circuit pack detected a loss of
multiframe alarm (LMA). An out of frame condition
occurred on the UDS1 interface circuit pack. The UDS1
interface circuit pack will transmit a remote multiframe
alarm (RMA) to the remote UDS1 endpoint until the LMA
is retired.
If the UDS1 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 UDS1 packs
and of the cable.
4. Replace the local UDS1 interface circuit pack, and
repeat the test.
If the UDS1 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 UDS1
interface circuit pack to the terminating device, and
check the premise distribution system (or the
intra-premise wiring) for physical connection
failures.
5. Replace the local UDS1 interface circuit pack and
repeat the test.
