TIE-DS1 (DS1 Tie Trunk)
Issue 1 May 2002
8-1145555-233-142
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 UUCSS 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 entries.
2. Test every administered trunk 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 every port fails, check the CARR-POW (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 far-end PBX. Make sure that the near- and far-end switches and
any NTCE equipment (the CSUs) have the correct administration.
6. Replace the circuit pack.
NOTE:
If the conference circuit test fails for every port on a circuit pack, a -5 Volt
power problem is indicated. If a TN736 or TN752 power unit circuit pack
is present, the power unit may be defective. To investigate problems with
a power unit, see the RMC-ENV MO. If a red LED on TN736 or TN752
power unit circuit pack is on, replace the pack.
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.
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’s 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.
