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. 

: 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 

on page 770 to investigate 

problems with either a 631DB AC or a 645B DC power unit. 

: If a TN736 or TN752 power unit circuit pack is present, the 

power unit may be defective. See 

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.
