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.

Result Description / Recommendation
ABORT System resources required for this test are not available.
1. Retry the command at 1-minute intervals up to 5 times.
1000 ABORT System resources required to run this test are not available. The port may be
in use on a valid call. Use the status access-endpoint extension command to
determine when the port is available for testing.
1004 ABORT The port has been seized by a user for a valid call. Use the status
access-endpoint extension command to determine when the port is available
for testing. The port is available when it is in the in-service/idle state.
1. Retry the command at 1-minute intervals up to 5 times.
1020 ABORT The test did not run due to a previously existing error on the specific port or
because of a more general circuit pack error.
1. Examine the Error Log for existing errors against this port or circuit pack,
and attempt to diagnose the previously existing error.
2000 ABORT Response to the test was not received within the allowable time period.
2100 ABORT System resources required for this test are not available.
1. Retry the command at 1-minute intervals up to 5 times.
FAIL The NPE of the tested port did not conference the tones correctly. This causes
noisy and unreliable connections. Even though wideband calls do not use the
conferencing feature on the NPE, this failure indicates problems with the circuit
pack hardware.
1. Replace the circuit pack.
PASS The port can correctly conference multiple connections.
1. Investigate user-reported troubles on this port using other port tests and by
examining the terminal adapter or external wiring.
