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.

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.
