Conference Circuit Test (#7)
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.
NOTE:
The TN464C or later UDS1 circuit pack has one SCOTCH-NPE chip instead
of several NPE chips.
Any FAIL The NPE of the tested port was found to be transmitting in error. This will
cause noisy and unreliable connections. The ISDN-TRK is moved to
out-of-service/near-end state.
1. Replace the circuit pack.
PASS The port is able to communicate over the TDM Bus.
