Conference Circuit Test (#7)
One or more NPEs reside on each circuit pack with a TDM Bus interface. The
NPE controls port connectivity and gain, and provides conferencing functions on
a per-port basis. The Conference Circuit Test verifies that the NPE channel for the
port being tested can correctly perform the conferencing function. The NPE is
instructed to listen to several different tones and conference the tones together.
The resulting signal is then measured by a Tone Detector port. If the level of the
tone is within a certain range, the test passes.
Any FAIL The test failed. This can be 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 TONE-BD and/or TONE-PT errors in the error log. If present,
refer to the TONE-BD Maintenance documentation and to the TONE-PT
Maintenance documentation.
2. Retest when the faults from step 1 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 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.
