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. 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.
7. 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. See
CARR-POW (Carrier Power Supply)
on page 770 to investigate
problems with either a 631DB AC or a 645B DC power unit.
S8700 IP: If a TN736 or TN752 power unit circuit pack is present, the
power unit may be defective. See RMC-ENV (Power/Fan
Sensors) on page 1951 to investigate problems with a power unit. If
a red LED is lit on TN736 or TN752 power unit circuit pack, 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.
