System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order they are p resented in the table b elow when
inspecting errors in the system. By clearing error c odes associated wi th the
NPE
Crosstalk Test,
for example, you may also clear errors gene rated from other tests
in the testing sequenc e.
NPE Crosstalk Test (#6)
One or more Network Processing Elements (NPEs) resides on each circ uit pack
with a TDM Bus interface. The NPE controls port connec tivity 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 selec ted time slot and never
crosses over to time slots reserved for other c onnections. If the NPE is not
working correctly, one-way and noisy connections may be ob served. This test is
usually only part of a port’s Lon g Test Sequence and takes about 20 to 30
seconds to comp lete.
