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.
