DS1-BD (DS1 Interface Circuit Pack)
Issue 1 May 2002

555-233-143
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
ds1-log UUCSS command to read the error seconds measurement.
Otherwise, skip this step.
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 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.

NO
BOARD
The test could not relate the internal ID to the port (no 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
command to administer the DS1 interface if it is not already administered.
2. If board was already administered correctly, check the error log to
determine whether the board is hyperactive. If so, the board was shut
down. Reseating the board will re-initialize it.
3. If the board was found to be correctly inserted in step 1, issue the busyout
board command.
4. Issue the reset board command.
5. Issue the release busy board command.
6. Issue the test board long command.
This should re-establish the linkage between the internal ID and the port.
