Conference Circuit Test (#7)
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.
NOTE:
The TN464C/D UDS1 circuit pack has one SCOTCH-NPE chip instead of
several NPE chips.

FAIL
The NPE of the tested port was found to be transmitting in error. This will
cause noisy and unreliable connections. The ISDN-TRK is moved to
out-of-service/near-end state.
1. Replace the circuit pack.
PASS
The port is able to communicate over the TDM Bus.
