Description/ Recommendation
1. Retry the reset board command at 1-minute intervals a maximum of 5
times.
2. Enter the list measurement ds1-log UUCSS command 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.
