FAIL The DS1 Interface circuit pack detects a Minor alarm. The DS1
bit error rate is greater than 1/1,000,000 and less than 1/1000.
1. The performance of DS1 link between DS1 Interface circuit
pack and remote DS1 endpoint is poor. If DS1 Interface
circuit pack is TN767, enter list measurement ds1-log
UUCSS command to read the error seconds
measurement.
2. Verify that both endpoints of the DS1 link are administered
using the same signaling mode, framing mode, and line
coding.
3. If the DS1 interface circuit pack connects to a T1 facility,
call the vendor of the T1 carrier to diagnose the remote
DS1 endpoint. If the DS1interface circuit pack connects
directly to a switch, call the system technician of the
remote switch to diagnose the DS1 endpoint.
4. Check the physical connection of the DS1 pack and of the
cable.
5. If this continues to fail, escalate this problem.
PASS No Minor alarm is detected in DS1 Interface circuit pack.
0 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. Check to ensure that the board 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 if the board is hyperactive. If this is
the case, the board is shut down. Reseating the board will
re-initialize the board.
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 link between the internal ID and
the port.
