ATM Board DSP Test (#1293)
Nondestructive
There are three kinds of digital signal processors (DSPs): talkers, listeners, and
echo cancelers.Talkers put data on the TDM bus, listeners take data off the TDM
bus, and echo cancelers filter out echoes of the main transmission. Firmware
allocates DSPs in sets of three (one of each type), up to a maximum of 8 sets.
This has three parts, one for each type of DSP. If the test fails for all DSPs, a
MAJOR alarm is raised. If the test fails for one or more DSPs, a MINOR alarm is
raised. If a DSP is busy, the test passes for that DSP. The test aborts if system
resources are not available. Each part of the test returns the number of DSPs that
passed or failed. This test run during initialization, error analysis testing, periodic,
scheduled, and craft short and long testing.

Result
Description/Recommendation
2031 FAIL The attempt to send the message to the ATM-TRK circuit pack was not
successful.
2500 FAIL Internal system error. Did not send the time of day information to the board.
Retry the command up to 3 times at 1-minute intervals.
If the test aborts with the same error code, escalate the problem.
PASS The ATM-TRK circuit pack is successfully updated with system time.
If the status port-network command still indicates that this link is down, it is
possible that one or both of the ATM-TRK circuit packs have been busied out.
If the link still does not come up, reset one or both ATM-TRK circuit packs on
the link.
0 NO
BOARD No board detected.
Check the error log for wrong board (Error 125) or no board (Error 131).
Resolve either of these issues, if applicable.
Check that the board is properly translated and inserted. If so, check for
hyperactivity (Error 1538). If hyperactive, use the reset board UUCSS
command.
Run the test again. If it fails, the board could be bad. Replace the board and
retest.
