Conference Circuit Test (#7)
One or more NPEs reside on each circuit pac k with a TDM Bus interface. The NPE controls port connectivity and gain, and provid es conferencing func tions on a per-port basis. The Conferenc e Circuit Test verifies that the NPE channel for the port being tested can correctly p erform the conferencing func tion. The NPE is instructed to listen to several d ifferent tones and conference the tones tog ether. The resulting signal is then measured b y a Tone Detector port. If the level of the tone is within a certain range, the test p asses.
Any FAIL The test failed. This can be due to on-board or off-board p roblems.
Off-b oard p robl ems of c oncer n inclu de EXP-IN TF faults, TDM-BUS f aults,
and faults associated with the tone detectors/tone generators. Clear all
off-board problems before replac ing 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 backp lane.
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 troub les on
this port should b e investigated using othe r 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 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 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.
