FAIL The UDS1 interface circuit pack detected a red alarm. An out of
frame condition occurred on the UDS1 interface circuit pack.
The UDS1 interface circuit pack will transmit a yellow alarm to
the remote UDS1 endpoint until the red alarm 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.
