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 measured by a tone
detector port. If the level of the tone is within a certain range, the test passes.
0 NO
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 busyout
board.
3. Issue reset board.
4. Issue release busy board.
5. Issue test board long. 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 list config,
but the
Vintage
field reports that there is no board when there
really is a board, busyout board and release busy board will not
work even though reset board works. The software puts the
hyperactive board back in service after the hyperactivity clears.
