Descriptions and Error Codes
Investigate tests in the order presented below. Clearing Error Codes associated with the one
test may also clear errors generated from other tests in the sequence.
NPE Crosstalk Test (#6)
One or more Network Processing Elements (NPEs) reside on each circuit pack with a TDM-bus
interface. (The TN464 UDS1 circuit pack has one SCOTCH-NPE chip instead of several NPE
chips.) 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.
