(cont’d) FAIL
(cont’d) Proceed as follows unless power or tone problems are suspected (see note
below).
1. To see if the problem is on-board, disconnect the port from the far end,
and retry the test. Coordinate this with the CO, or do it after busy hours.
2. If the retry fails, replace the circuit pack.
3. If the retry passes and no troubles have been reported, disable the test in
the trunk group administration. If the retry passes and troubles are
reported, coordinate isolation with the CO.
NOTE:
If the loop-around and conference circuit test fails for every port on a
circuit pack, a -5V power problem is indicated. A power unit may be
defective (CARR-POW). If the test fails on more than 1 port, check for
errors on the TONE-BD or the TONE-PT MOs.
4. Rerun the test.
PASS DID Trunk Looparound and Conference test is successful. This port is
functioning properly.
1. If users are reporting troubles, examine loop connections to the port and
refer problem to the CO.
0 NO
BOARD The test could not relate the internal ID to the port (no board).
1. Verify that the board’s translations are correct.
2. Issue the busyout board command.
3. Issue the reset board command.
4. Issue the release busy board command.
5. Issue the test board command. This should establish the link between
the internal ID and the port.
