Conference Circuit Test (#7)
The Conference Circuit test verifies that the NPE channel for the port b eing
tested can correc tly perform the conferenc ing function. The NPE is instructed to
listen to several different tones and c onference the tones together. The resulting
signal is then measured by a to ne detector port. If the leve l of the tone is within a
certain range, the test p asses.
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 p ort or the circuit p ack
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.
