If the UDS1 connects to a line-side terminating device such as a PRI 
terminal adapter:

1. Retry reset board location at 1-minute intervals up to 5 times.
2. Enter list measurement ds1-log location to read the error 

seconds measurement.

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

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

4. 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.

5. Check the physical connection of the UDS1 Interface circuit pack to 

the terminating device. Check premise distribution system (or 
intra-premise wiring) for physical connection failures. If the error 
seconds measurement is severe, investigate premise distribution 
system wiring for noise and distance limitation.

6. Replace the local UDS1 Interface circuit pack, and repeat the test.

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

equipment.

 

PASS

Every administered trunk or port of the UDS1 Interface circuit pack passes 

the Internal Loop-Around test. The bit pattern consistency test is executed 

successfully over the path that covers a DS1 port, cable, and the external 

NCTE device.
