ATM Board DSP Test (#1293)
This test is nondestructive and is designed to test the board’s interface to the
TDM bus and the functions of all 24 on-board 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 cancelers are tightly coupled because firmware allocates sets
of DSPs. Since there are a total of 24 DSPs on the board, there can 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 up to 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 up to 5 times.
1962 ABORT Every TALKER DSP is busy (an unlikely event).
1. Retry the command at 1-minute intervals up to 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 up to 3 times.
2752 ABORT The circuit pack in this location is not a TN230X.
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 up to 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.
