Minor alarms are often accompanied by slip and misframe alarms against 
the board. Trunk alarms and hardware error logs may occur on the 
associated trunks.

If the UDS1 connects to a T1 network facility or to another switch, do the 

following:

1. The performance of the DS1 link between the UDS1 interface circuit 

pack and the remote DS1 endpoint is poor. Enter list 
measurement ds1-log location to read the error seconds 

measurement.

2. Verify that both endpoints of the DS1 link are administered using the 

same signaling mode, framing mode, and line coding.

3. Contact T1 Network Service or the technician at the remote switch to 

diagnose the equipment.

4. Check the physical connectivity of the UDS1 interface circuit packs 

and the cable.

5. 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. The performance of the DS1 link between the UDS1 interface circuit 

pack and the line-side terminating device is very poor. Enter list 
measurement ds1-log location to read the error seconds 

measurement.

2. Verify that the switch DS1 and the line-side terminating device are 

administered using the same signaling mode, framing mode, and line 
coding.

3. Investigate the maintenance status of the line-side terminating 

device. Obtain the error seconds measurement on the terminating 
device (if possible). Refer to the 'Line-Side Terminating Device 
Operating Manual' for information.

4. Contact the vendor of the line-side terminating device to diagnose the 

equipment.

5. 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.

6. Replace the local UDS1 interface circuit pack and repeat the test.
