Conference Circuit Test (#7)
One or more Network Processing Elements (NPEs) reside on each circuit pack
with a TDM-bus interface. The NPE controls port connectivity and gain, and
provides conferencing functions on a per-port basis. 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.

Test
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
busy with a valid call and therefore unavailable for certain tests. Wait until the
port is idle (amber LED is off) before retesting.
1. If the port is idle, retry the command at 1-minute intervals up to 5 times.
1004
ABORT
The port was seized by a valid call during the test and the test has been
aborted. Wait until the port is idle (amber LED is off) before retesting.
1. Retry the command at 1-minute intervals up to 5 times.
1020
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.
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 NPE of the tested port did not conference the tones correctly. This causes
noisy and unreliable connections.
1. Retry the test.
2. If the test continues to fail, then replace the circuit pack.
PASS
The port can correctly conference multiple connections. User-reported troubles
on this port should be investigated using other port tests and by examining the
Error Log.
