MP Diagnostic Test (#1406)
This test is destructive.
The MP Diagnostic Test (#1406) runs all of the diagnostic tests listed below, in the
order listed, but only if each successive test passes:
1. FPGA Query
2. TSI Query
3. ETHERNET Query
4. SCOTCH Sanity
FPGA Query
This test passes if the FPGA device on the TN2302 tests ok. Otherwise it fails with
no fail code or AUX data.
This test verifies the status of the FPGA device on the TN2302 circuit pack. If the
device is bad, software sets an appropriate counter, posts an error and alarm, and
takes all DSPs out of service (all DSPs are controlled by the one FPGA). Software
then attempts to reset the FPGA. If the reset passes or the original test passes,
the DSPs are placed into service.
TSI DSP Query
This test passes if the TSI device on the TN2302 tests ok. Otherwise it fails with
no fail code or AUX data.
This test verifies the status of the TSI device on the TN2302 circuit pack. If the
device is bad, software sets an appropriate counter, posts an error and alarm, and
takes all DSPs out of service (all DSPs are controlled by the one TSI). Software
then attempts to reset the TSI. If the reset passes or the original test passes, the
DSPs are placed into service.
Ethernet Query
This test passes if the TN2302 hardware tests ok and the Ethernet port is
connected. Otherwise it fails with no fail code or AUX data.
SCOTCH Sanity
The Scotch device on a board communicates with switch software via the TDM
bus for conferencing and gain adjustment. This is done by setting up connections
on TDM bus time slots.
There are 3 different inline errors that can be generated due to the Scotch devices
on the board: NPE SCOTCH 0, NPE SCOTCH 1, and NCE SCOTCH. If any of
these errors are reported from the board, the DSPs are taken from service and a
circuit pack reset is executed by running the SAKI test.
