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 or later UDS1 circuit pack has one SCOTCH-NPE chip instead
of several NPE chips.

ABORT
The test did not run due to an already existing error on the specific port or a
more general circuit pack error.
1. Examine Error Log for existing errors against this port or the circuit pack
and attempt to diagnose the already existing error.

ABORT
Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
Any
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.
