This test reads and clears the port’s Layer 1 Transmission error counter maintained on the ASAI or 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. It does not indicate a problem with the circuit pack. This test is useful for verifying the repair of the problem.

This test runs on ASAI-PT (ASAI Port).
