CRC Error Counter Test (#623)
This test reads and clears the BRI port’s CRC error counter maintained on the BRI-LINE circuit
pack. This counter is incremented by the circuit pack when it receives a frame from the
endpoint or adjunct with a bad CRC over the D channel. The test passes if the value of the
counter is 0 (the error is cleared). If the counter is not 0, the test fails and the value of the
counter is displayed in the Error Code field. A CRC error is most likely due to a problem with
the wiring to the set or adjunct, interference on the wiring due to a noise source (for example,
electrical motors or generators), or no termination (open circuit). It usually does not indicate a
problem with the BRI circuit pack. This test is used for verifying the repair of the problem.
3 FAIL Received a status of Level 1 Deactivated; the port is out of service.
1. Enter status bri-port location to verify that the service state
of the port is out-of-service. If the port is not out of service, escalate
the problem, or else proceed to step 2.
2. If the port has been placed out-of-service using busyout port
location, use release port location. Then enter test
port long location and review the results of Level 1 Status
Inquiry test. If this test still fails, proceed to step 3.
3. After executing test port long location review the results of
every test. Follow the repair procedures for any tests that fail. Verify
repair of the problem by executing test port location and by
determining that the Level 1 Status test passes.
4. If the test continues to fail for this reason, escalate the problem.
PASS This test indicates that Level 1 is activated, or that software has taken the
port out of service.
