Conference Circuit Test (#7)
One or more Network Processing Elements (NPEs) reside on each circ uit pack
with a TDM Bus interface. (The TN464C/D UDS1 circuit pack has one
SCOTCH-NPE chip instead of several NPE chips). The NPE controls port
connectivity and g ain, and provides c onferencing functions on a per-port basis.
The Conference Circuit Test verifies that the NPE channel for the port being
tested can correc tly perform the conferenc ing function. The NPE is instructed to
listen to several different tones and c onference the tones together. The resulting
signal is then measured by a Tone Detector port. If the le vel of the tone is within a
certain range, the test p asses.
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.
