Layer 1 Transmission Error Counter Test (#624)
This test reads and clears the BRI port’s Layer 1 Transmission error counter
maintained on the ASAI circuit pack. This counter is incremented by the circuit
pack when it detects a Layer 1 transmission problem. The test passes if the value
of the counter is 0 (that is, the error is cleared). If the counter is not zero, the test
fails, and the value of the counter is displayed in the Error Code field.
This error is most likely due to a problem with the wiring or adjunct (verify that the
wiring meets the configuration rules defined in
DEFINITY Communications
System Generic 1 and Generic 3i Wiring
, 555-204-111). It does not indicate a
problem with the TN800 circuit pack. This test is useful for verifying the repair of
the problem.

Result Description/Recommendation
2000 ABORT Response was not received from the circuit pack within the allowable time
period.
1. If the test aborts repeatedly a maximum of 5 times, reset the circuit
pack using the busyout board UUCSS and reset board UUCSS
commands.
2. If the test aborts again, replace the circuit pack.
!
CAUTION:
Do not leave the circuit pack busied out.
2012 ABORT Internal system error
1. Retry the command at 1-minute intervals for a maximum of 5 times.
Any FAIL The BRI circuit pack is still detecting CRC errors. The Error Code field
contains the value of the counter.
1. Retry the command at 1-minute intervals for a maximum of 5 times.
2. If the test continues to fail, review the restuls of other tests in the long
test sequence. Pay particular attention to the results of the Level 1
Status Inquiry test. Follow the repair procedures for any of the executed
tests if they fail; otherwise, proceed to Step 3.
3. If the tests for the endpoints or adjunct pass and the CRC error counter
test continues to fail, check the wiring to the endpoints or adjunct. If the
wiring appears to be OK, escalate the problem.
