Conference Circuit Test (#7)
One or more Network Processing Elements (NPEs) reside on each circuit pack
with a TDM Bus interface. (The TN464C UDS1 circuit pack has one
SCOTCH-NPE chip instead of several NPE chips). The NPE controls port
connectivity and gain, and it 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 to 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.
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 one minute intervals a maximum of five times.
2. If the test continues to abort, and if the port is not in use, escalate the
problem.
1020 ABORT The test did not run due either to a previously existing error on the specific
port or to a more general circuit pack error.
1. Examine the 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 System resources required for this test are not available.
1. Retry the command at one minute intervals a maximum of five times.
2. If the test continues to abort, escalate the problem.
FAIL The NPE of the tested port was found to be transmitting in error. This
causes noisy and unreliable connections.
1. Replace the circuit pack.
PASS The port is correctly using its allocated time slots.
1. User-reported troubles on this port should be investigated by using
other port tests and by examining the terminal adapter or the external
wiring.
