NPE Crosstalk Test (#6)
The NPE Crosstalk Test verifies that this port’s NPE channel talks on the se lected
time slot and never crosses over to time slots rese rved for other connections. If
the NPE is not working correctly, one-way and noisy connec tions may be
observed. This test is usually only part o f a port’s long test seq uence and takes
about 20 to 30 seconds to c omplete.
NOTE:
The TN464C/D UDS1 circuit pack has one SCOTCH-NPE chip instead of
several NPE chips.
