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. 

: 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 

page 770. If a red LED on TN736 or TN752 power unit circuit pack is 

on, replace the pack.

: 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 

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.
