NPE Crosstalk Test (#6)
The NPE Crosstalk 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 usually only part of a port’s Long Test Sequence and takes
about 20 to 30 seconds to complete.
NOTE:
The TN464C or later UDS1 circuit pack has one SCOTCH-NPE chip instead
of several NPE chips.
