Conference Circuit Test (#7)
This test verifies that the NPE channel for the port being tested can correc tly perform the conferencin g function.
Any FAIL This test can fail due to on-board or off-board problems. Off-board
problems 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 b oard. A TDM-BUS problem is usually the
result of a faulty board connected to the backp lane, or bent pins on the
backplane.
1. Look for EXP-PN and/or EXP-INTF errors in the error log. If present,
refer t o “EXP-PN” and “EXP-IN TF”.
2. Look for TDM-BUS errors in the error log. If present, refer to
“TDM-BUS”.
3. Look for TONE-BD and/or TONE-PT errors in the error log. If present,
refer to “TONE-BD” and “TONE-PT”.
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 is correctly using its allocated time slots. User-reported troubles
on this port should be investigated by using other port tests, by examining
station wiring, or by examining the station.
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 b oard 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.
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.
