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 passes.
Any 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.
User-reported troubles on this port should be
investigated using other port tests and examining the
Error Log.
