Conference Circuit Test (#7)
The Conference Circuit test verifies that the NPE channel for the port b eing
tested can correc tly perform the conferencing function. The NPE is instructed to
listen to several different tones and c onference the tones together. The resulting
signal is then measured by a tone d etector port. If the level of the ton e is within a
certain range, the test p asses.
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.
