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
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.
