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.

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.
