Descriptions and Error Codes
Always investigate tests in the order presented in the following tables when
inspecting errors in the system. By clearing error codes associated with the
inspecting errors in the system. By clearing error codes associated with the
Analog Port Sanity Test
, for example, you may also clear errors generated from
other tests in the testing sequence.
NPE Crosstalk Test (#9)
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.
time slot and never crosses over to time slots reserved for other connections.
One or more Network Processing Elements (NPE) reside on each circuit pack
with a TDM Bus interface. The NPE controls port connectivity, gain, and provides
conferencing functions on a per port basis. If the NPE is not working correctly,
one way and/or noisy connections may be observed. This test is part of a port’s
long test sequence and takes approximately 10 to 20 seconds to complete
with a TDM Bus interface. The NPE controls port connectivity, gain, and provides
conferencing functions on a per port basis. If the NPE is not working correctly,
one way and/or noisy connections may be observed. This test is part of a port’s
