(cont’d.)
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 poor. Enter the list measurement ds1-log
PCSS command 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.
7. If the test still fails, escalate the problem.
PASS No Minor alarm is detected in the UDS1 Interface circuit
pack.
