Layer 1 Transmission Error Counter Test (#624)

This test reads and clears the BRI port's Layer 1 Transmission error counter
maintained on the BRI-LINE 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 the endpoint 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 ISDN-BRI circuit pack. This test is useful for
verifying the repair of the problem.

Description/ Recommendation
Response to the test 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 with busyout board PCSS and reset board PCSS.
2. If the test aborts again, replace the circuit pack.
Internal system error
Could not allocate necessary system resources to run test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
The BRI-LINE circuit pack is still detecting errors of this type. The Error
Code field contains the value of this counter.
1. Retry the command at 1-minute intervals a maximum of 5 times.
2. If the test continues to fail, review the results of other tests in the
Long Test Sequence. Look at the results of the Level 1 Status
Inquiry test. Follow repair procedures for any of the executed tests if
they fail. Otherwise, go to the next step.
3. If the tests for the endpoints or adjunct pass and the Layer 1
Transmission Error Counter Test continues to fail, check the wiring
to the endpoints or adjunct.
The Layer 1 Transmission error counter was read correctly and has a
value of 0.
