Conference Circuit Test (#7)
One or more Network Processing Elements (NPEs) reside on each circuit pack with a TDM-bus
interface. (The TN464 UDS1 circuit pack has one SCOTCH-NPE chip instead of several NPE
chips). 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 passes.
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 list
config, and resolve any problems that are found.
2. If the board was found to be inserted correctly, enter busyout
board location.
3. Enter the reset board location command.
4. Enter the release board location command.
5. Enter test board location long.
This should re-establish the linkage between the internal ID and the
port. If not, ensure that there is a valid board inserted.

ABRT System resources required for this test are not available.
1. Retry the command at 1-minute intervals up to 5 times.
1000 ABRT Could not seize the port for testing. The port may be in use on a valid call.
Use status station or status trunk to determine when the port is
available for testing.
