PE-BCHL (PRI Endpoint Port)

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.
1117 ABORT A service state audit message is outstanding.
1. Wait 2 minutes and then try again.
2000 ABORT Response to the test request was not received within the
allowable time period.
1. Retry the command at 1-minute intervals a maximum of 5
times.
2020 ABORT The test did not run due either to an already 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.
2100 ABORT Could not allocate the necessary system resources to run this
test.
1. Retry the command at 1-minute intervals a maximum of 5
times.
Any FAIL The NPE of the tested port was found to be transmitting in
error. This causes noisy and unreliable connections. The
PE-BCHL is moved to the out-of-service/near-end state.
1. Replace the circuit pack.
PASS The port is able to communicate over the TDM Bus.
