Any FAIL This test can fail due to on-board or off-board problems.
Off-board problems of concern include 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-INTF errors in the error log. If present, refer
to 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. Retest the board when the faults from steps 1 and 2 are
cleared.
PASS The port is correctly using its allocated time slots.
User-reported troubles on this port should be investigated
using other port tests and 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 list config, and resolve any problems that are found.
2. If the board was found to be correctly inserted in step 1,
issue busyout board.
3. Issue the reset board command.
4. Issue the release busy board command.
5. Issue test board long. 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.
