NPE Crosstalk Test (#6)
This test verifies that this port’s NPE channel talks on the selected time slot and
never crosses over to time slots reserved for other connections. If the NPE is not
working correctly, one-way and noisy connections may be observed. This test is
part of the long test sequence and takes about 25 seconds to complete.
