CRC Error Counter Test (#623)
This test reads and clears the BRI port’s C RC error counter maintained on the
BRI-LINE circuit pack. This counter is inc remented by the circ uit pack when it
receivs a frame from the endpoint or ad junct with a bad CRC over the D-channe l.
The test passes if the value of the counter is 0 (the error is cleared ). If the counter
is not 0, the test will fail and the value of the c ounter is displayed in the Error
Code field. A CRC error is most likely due to a prob lem with the wiring to the set
or adjunct, interference on t he wiring due to a noise source (for example,
electrical motors or genera tors), or no termination (open circ uit). It usually does
not indicate a prob lem with the BRI circuit pac k. 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. Issue the status bri-port UUCSSpp command 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 the busyout port
UUCSSpp command, try releasing the port by exec uting the release
port UUCSSpp command. Then issue the test port long UUCSSpp
command, and review the results of Level 1 Status Inquiry test. If this
test is still failing, proceed to Step 3.
3. After executing the test port long UUCSSpp command , review the
results of all the tests. Follow the repair procedures for any tests that fail.
Verify repair of the problem by executing the test port UUCSSpp
command 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.
