Conference Circuit Test (#7)
One or more 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 passed.
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, 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, check to see that
there is a valid board inserted.
