Conference Circuit Test (#7)
The Conference Circuit Test verifies that the NPE channel for the port being
tested can correc tly perform the conferenc ing function. The NPE is instructed to
listen to several different tones and c onference the tones together. The resulting
signal is then measured by a to ne detector port. If the leve l of the tone is within a
certain range, the test p asses.
FAIL The NPE of the tested port was found to be transmitting in error. This will
cause noisy and unrelia ble connections.
1. Replace the circuit pack.
PASS The port is correctly using its allocated time slots. User-reported troub les on
this port should b e investigated using other port tests and exam ining
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, an insane board is inserted, or the b oard is hyperact i ve.
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-e stablish 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.
NOTE:
Hyperactivity causes some special problems with the sequence
suggested above. If the ports are translated after issuing the list
config command but the ’Vintage’ field reports that there is no board
(when there really is a board), then the busyout board and the
release busy board commands will not work (even though the reset
board command will work). The software will put the hyperactive
board back in service after the hypera ctivity clears.
