2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the reset board command at 1-minute intervals for a maximum of 5
times.
FAIL The UDS1 Interface circuit pack failed in the Internal Looparound Test.
If the UDS1 connects to a T1 network facility or another switch:
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 both endpoints of the DS1 link are administered using the same
signaling mode, framing mode, and line coding.
4. Check the physical connectivity of DS1 Interface circuit packs and c able.
5. Replace the local UDS1 Interface circuit pack and repeat the test.
6. Contact T1 Network Service to diagnose the remote DS1 endpoint.
FAIL
(cont’d.)
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 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.
