ATM Board DSP Test #1258 (TN2238 only)
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).
This looparound test is comple tely on-board, and the results for eac h DSP are
saved until all DSPs are tested.
If the test fails for all DSPs, a MAJOR alarm is raised against the b oard. If the test
fails for one or more DSPs, the test fails and a MINOR alarm is raised. If a DSP is
“busy,” the test for that partic ular DSP is considered passed . The test aborts if
the system resources (for example, the TDM time slots, tone generator, and
others) are not available. This test applies to al l ATM-EIs, both active and
standby, and is run as part of c raft short and long testin g, periodic, scheduled,
initialization, and error analysis testing. Refer to Fi gure 9-6 for a diagram of this
looparound test.

Result Description/ Recommendation
2000 ABORT Response to the test request was not received within the allowable time
period.
1. Retry the command at 1-minute intervals for a maximum of 3 retries.
2. If the test fails repeatedly, attempt to reset the circuit pack.
3. If the test continues to fail, replace the circuit pack.
2012 ABORT Internal system error
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
ANY FAIL The transmitted data packet was not received correctly by the Packet
Interface circuit pack. The failure may be in the ATM-EI under test, the DS1
CONV circuit packs, or the intervening Center Stage components.
1. Retry the command at 1-minute intervals a maximum of five times
2. If the test continues to fail, replace the circuit pack.
PASS The Packet Interface Test passed.
