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.
2020 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.
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals for 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.
