FAIL This can be due to on-board or off-board problems. Off-board
problems of concern include EXP-PN and EXP-INTF faults,
TDM-BUS faults, and faults associated with the tone
detectors/tone generators. Clear all off-board problems before
replacing the board. Keep in mind that a TDM-BUS problem is
usually the result of a faulty board connected to the backplane
or bent pins on the backplane.
1. Look for EXP-PN and/or EXP-INTF errors in the error log.
If present, refer to the EXP-PN Maintenance
documentation and the EXP-INTF Maintenance
documentation.
2. Look for TDM-BUS errors in the error log. If present, refer
to the TDM-BUS Maintenance documentation.
3. Look for TONE-BD and/or TONE-PT errors in the error log.
If present, refer to the TONE-BD Maintenance
documentation and the TONE-PT Maintenance
documentation.
4. Retest when the faults from steps 1, 2, and 3 are cleared.
Replace the board only if the test fails.
PASS The port is correctly using its allocated time slots.
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, check to see that there is a
valid board inserted.
