NPE Crosstalk Test (#6)
One or more Network Processing Elements (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 approximately 20 to 30
seconds to complete.

BOARD
The test could not relate the internal ID to the port (no board).
1. Check to ensure that the board translations are correct. Translate the
board, if necessary.
2. Issue the busyout board command.
3. Issue the reset board command.
4. Issue the release busy board command.
5. Issue the test board command. This should re-establish the linkage
between the internal ID and the port.
