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.
0NO
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 the list config command, 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, dispatch to check to
ensure that there is a valid board inserted.
