Conference Circuit Test (#7)
One or more Network Processing Elements (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.
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, an insane board is inserted, or the board is hyperactive (see note
below).
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.
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 hyperactivityclears.
