ATM Board DSP Test (#1293)
This test is non-destructive and is d esigned to test the board ’s interface to the
TDM bus and the functions of all 24 on-b oard DSPs (Digital Signal Processors).
There are three functional types of DSPs:
■talkers - put data on the TDM bus
■listeners - take data off the TDM bus
■echo cancelers - as implied
Listener and echo canc elers are tightly coup led because firmware alloc ates

sets

of DSPs. Since there are a total of 24 DSPs on the board, there may be up to 8
triplets allocated.
1003 ABORT The system could not allocate a tone receiver for the test. The system
may be oversized for the number of tone detectors present or some tone
detectors may be out -of-service.
1. Resolve any TTR-LEV errors in the Error Log.
2. Resolve any TONE-PT errors in the Error Log.
3. If neither condition exists, retry the test at 1-minute intervals for a
maximum of 5 times.
2000 ABORT Response to the test was not received within the allowable time period.
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals for a maximum of 5 times.
1962 ABORT All the TALKER DSPs are busy (an unlikely event).
1. Retry the command at 1-minute intervals a maximum of 3 times.
2302 ABORT Inconsistent uplink message from the ATM-EI board. This is a very
unlikely event.
1. Retry the command at 1-minute intervals a maximum of 3 times.
2752 ABORT The circuit pack in this location is not a TN2305/TN2306.
1-8,
None FAIL The board is writing to unauthorized TDM time slots. The error code
indicates the number of faulted TALKER DSPs.
1. Retry the command at 1-minute intervals a maximum of 3 times.
2. If the failure persists, replace the circuit pack.
1-8 PASS The board is not talking to unauthorized time slots on the TDM Bus. The
error code indicates the number of TALKER DSPs that were tested.
