If the UDS1 connects to a line-side terminating device such as a PRI
terminal adapter:
1. Retry the reset board command at 1-minute intervals a maximum of 5
times.
2. Enter the list measurement ds1-log PCSS 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.
8. If the test still fails, then escalate the problem.
PASS All administered trunks or ports of the UDS1 Interface circuit pack pass 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.
