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. 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.
S8700 MC: 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 contain 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 or
645B DC power unit, see CARR-POW (Carrier Power Supply)
on
page 770. If a red LED on TN736 or TN752 power unit circuit pack is
on, replace the pack.
S8700 IP: 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 RMC-ENV (Power/Fan Sensors)
on page 1951.
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.
