Error Test
Code Result Description / Recommendation
FAIL DS1 Interface circuit pack failed in the Internal Looparound test.
1. Retry the command at 1-minute intervals up to 5 times.
2. If the DS1 Interface circuit pack is TN767, enter the list measurement
3. Verify that both endpoints of the DS1 link are administered using the same
4. Check the physical connectivity of DS1 Interface circuit packs and cable.
5. Contact T1 Network Service to diagnose remote DS1 endpoint.
6. If all of the above are OK, escalate this problem.
PASS All administered trunks of DS1 Interface circuit pack pass the Internal
Looparound test. The bit pattern consistency test is executed successfully over
the path that covers a DS1 port, cable, and the external NCTE device.
0 NO The test could not relate the internal ID to the port (no board).
BOARD
This could be due to incorrect translations, no board is inserted, an incorrect
board is inserted, or an insane board is inserted.
1. Verify that the board's translations are correct. Use the add ds1 UUCSS
2. If board was already administered correctly, check the error log to
3. If the board was found to be correctly inserted in step 1, issue the busyout
4. Issue the reset board command.
5. Issue the release busy board command.
6. Issue the test board long command.
