1 FAIL The test failed. 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 UD S1 interface circuit pac k, 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 devic e, and check the prem ise distribution system (or the
intra-premise wiring) for physical connection failures.
5. Replace the local UDS1 interface circuit pack and repeat the test.
