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 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 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. If a TN736 or TN752 power unit circuit pack
is present, either the 631DB AC power unit or the 676B DC power unit
may be defective. (The 631DB power unit is used in a medium cabinet
powered by an AC source. The 645B power unit is used in a medium
cabinet powered by a DC power source.) The system may co ntain a
TN736 or TN752 power unit or a 631DB AC power unit, but not both
types of power units. To investigate problems with a 631DB AC power
unit, refer to the CARR-POW (carrier port power unit for AC-powered
systems) Maintenance documentation. To investigate problems with a
645B DC power unit, refer to the CARR-POW (carrier port power unit for
DC-powered systems) Maintenance documentation. 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 ex te rnal wiring.
