Any FAIL The NPE of the tested port did not conference the tones correctly. This can
cause noisy and unreliable connections.
1. Enter the list configuration board PCSS command. If the circuit pack is
a TN767B vintage 8 or 9, replace the circuit pack with a TN767C V3 or
later. The error log may have error type 1281.
2. Test all administered trunks on the board. If one fails, this could be an
off-board problem (such as an incoming seizure or an off-hook port
seizure during the test). Retest the board.
3. If all of the ports fail, check the CABINET (see note below).
4. If several ports fail, check the error log for TONE-BD or TONE-PT errors. If
there are such errors, take the appropriate action. When the TONE errors
have cleared, rerun the test.
5. If the retry passes and troubles have been reported, coordinate isolation
with the CO. Make sure that the switch, the CO, and any NTCE
equipment (the CSUs) have the correct administration.
6. Replace the circuit pack.
NOTE:
If the conference circuit test fails for all ports on a circuit pack, a -5 volt
power problem is indicated.
PASS The port can correctly conference multiple connections. User-reported
troubles on this port should be investigated using other port tests and by
examining station, trunk, or external wiring.
NOTE:
This test always passes for TN742 Analog circuit packs prior to
Vintag e 4.
0NO
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 lIst
config command and resolve any problems that are found.
2. If the board was found to be correctly inserted in step 1, issue the
busyout board command.
3. Issue the reset board command.
4. Issue the release busy board command.
5. Issue the test board long command. This should re-establish the linkage
between the internal ID and the port. If this is not the case, check to see
that there is a valid board inserted.
