System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order presented in the table below when inspecting
errors in the system. By clearing error codes associated with the NPE Crosstalk
Test, for example, you may also clear errors generated from other tests in the
testing sequence.

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.
