TIE-DS1 (DS1 Tie Trunk)
Issue 4 May 2002
10-1747 555-233-123
2053 ABORT At least one of the following errors is found on the DS1 circuit
pack: 1281—Loss of signal, 1793—Blue Alarm, 2049—Red
Alarm, 2305—Yellow Alarm, 1537—Hyperactivity.
Look for the above error types in the Hardware Error Log and
follow the procedures given in the appropriate DS1-BD or
UDS1-BD maintenance documentation for the listed error
types.
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 UUCSS . 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 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 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-end and far-end switches and any NTCE
equipment (the CSU's) have the correct administration.
