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 Could not allocate the necessary system resources to run this test.
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 status data-module to determine when the port is
available for testing.
1004 ABORT The port has been seized by a user for a valid call. Use status data-module to
determine when the port is available for testing.
1. Retry the command at 1-minute intervals up to 5 times.
1020 ABORT An existing Error Type #769 on this port prevented the test from running.
1. Follow the procedure following the Error Log Table for Error Type #769.
2000 ABORT Response to the test request was not received within the allowable time period.
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
Any FAIL The conference circuit test failed (possible off-board problem).
1. Busyout and release the port (data line), and then retest.
2. Replace the circuit pack if the test continues to fail.
PASS The port can correctly conference multiple connections. Investigate
user-reported troubles on this port using other port tests and examining the
ADU, external wiring, and customer equipment.
