Conference Circuit Test (#7)
One or more Network Processing Elements (NPEs) reside on each circ uit pack
with a TDM Bus interface. (The TN464C UDS1 circuit pack has o ne
SCOTCH-NPE chip instead of several NPE chips.) The NPE controls port
connectivity and g ain, and it provides c onferencing functions on a p er port basis.
The Conference Circuit test verifies that the NPE channel for the port b eing
tested can correc tly perform the conferenci ng function. The NPE is instructed to
listen to several different tones and to c onference the tones together. The
resulting signal is then measured b y a tone detector p ort. If the level of the tone is
within a certain range, the test p asses.
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.

Test
Result Description/Recommendation
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.
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 pri-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
pri-endpoint <extension> command to determine when the port is available
for testing.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1020 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 Error Log for existing errors against this port or against the
circuit pack, and attempt to diag nose the already existing error.
