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 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 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
external wiring.

NO
BOARD
The test could not relate the internal ID to the port (no board).
This could be due to incorrect translations, no board is
inserted, an incorrect board is inserted, or an insane board is
inserted.
1. Check to ensure that the board translations are correct.
Use list config , and resolve any problems that are found.
2. If the board was found to be correctly inserted in step 1,
issue the busyout board command.
3. Issue the reset board command.
4. Issue the release busy board command.
5. Issue the test board long command. This should
re-establish the linkage between the internal ID and the
port. If this is not the case, check to see that there is a
valid board inserted.
