Conference Circuit Test (#7)
One or more Network Processing Elements (NPEs) reside on each circuit pack
with a TDM Bus interface. (The TN464C UDS1 circuit pack has one
SCOTCH-NPE chip instead of several NPE chips). The NPE controls port
connectivity and gain, and it 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 to 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.
FAIL The NPE of the tested port was found to be transmitting
in error. This causes noisy and unreliable connections.
1. Replace the circuit pack.
PASS The port is correctly using its allocated time slots.
1. User-reported troubles on this port should be
investigated by using other port tests and by
examining the terminal adapter or the external
wiring.

Result Description/ Recommendation
ABORT System resources required for this test are not available.
1. Retry the command at one minute intervals a
maximum of five times.
2. If the test continues to abort, escalate the problem.
1000 ABORT System resources required to run this test are not
available. The port may be in use on a valid call. Use the
status access-endpoint <extension> command to
determine when the port is available for testing.
