DID-DS1 (Direct Inward Dial Trunk)
Issue 1 June 2005 895
Any FAIL The NPE of the tested port did not conference the tones correctly. This
can cause noisy and unreliable connections.
1. Enter list configuration board location. The circuit pack
must be a TN767C V3 or later. The error log may have Error Type
#1281.
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, a -5V power problem is indicated. Check
CARR-POW (Carrier Power Supply)
on page 770.
4. If several ports fail, resolve any TONE-BD (Tone-Clock Circuit)
on
page 2327 or TONE-PT (Tone Generator)
on page 2353 errors and
rerun the test.
5. If the retry passes and troubles are 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.
PASS The port can correctly conference multiple connections. Investigate
user-reported troubles on this port using other port tests and by examining
station, trunk, or external wiring.
This test always passes for TN742 Analog circuit packs prior to Vintage 4.

BOARD
The test could not relate the internal ID to the port. 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 lIst config,
and resolve any problems that are found.
2. If the board was found to be correctly inserted in step 1, enter
busyout board location
3. Enter reset board location
4. Enter release board location
5. Enter test board location long
This should re-establish the link between the internal ID and the port.
If not, check to see that there is a valid board inserted.
