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.
