Port Diagnostic Test (#35)
This test checks a port’s battery feed circuitry. The battery feed circuitry is tested
for proper battery voltage by testing the switchhook state. In response to the test
message, the on-board firmware terminates the line and checks for switch-hook
presence. The termination is then removed, and a check is made for no
switch-hook presence. The MET set must be on-hook for the test to execute.
Any FAIL This test can fail 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. Resolve any EXP-PN and/or EXP-INTF errors.
2. Resolve any TDM-BUS errors.
3. Resolve any TONE-BD and/or TONE-PT errors.
4. Test the board when the faults from steps 1, 2, and 3 are cleared. Replace
the board only if the test fails.
PASS The port uses its allocated time slots correctly. Investigate user-reported
troubles on this port 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
ensure that there is a valid board inserted.
