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.

Description / Recommendation
2000 ABRT Response was not received from the circuit pack within the allowable time
period.
1. If the test aborts repeatedly up to 5 times, reset the circuit pack using
busyout board location and reset board location.
2. If the test aborts again, replace the circuit pack.

CAUTION:
CAUTION: Do not leave the circuit pack busied out.
2012 ABRT Internal system error
1. Retry the command at 1-minute intervals up to 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 up to 5 times.
2. If the test continues to fail, review the results 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.
