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 Battery Feed
Test, for example, you may also clear errors generated from other tests in the
testing sequence.

Order of Investigation
Battery Feed Test (#35)

NPE Crosstalk Test (#6)
One or more NPEs reside on each circuit pack with a TDM Bus interface. The
NPE controls port connectivity and gain, and provides conferencing functions on a
per-port basis. 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.
