NPE Crosstalk Test (#9)
NPE Crosstalk Test (#9) verifies that this port’s NPE channel talks on the selected time slot and
that it never crosses over to time slots reserved for other connections. An NPE that is not
working correctly may cause 1-way and noisy connections. This test is part of a port’s long test
sequence, and it executes in about 20 to 30 seconds.
