CRC Error Counter Test (#623)
This test is non-destructive.
This test reads the BRI port’s CRC error counters that are maintained on the BRI
circuit pack. The Cyclic Redundancy Check (CRC) is a means of error detection
used to determine the integrity of data frame contents. The CRC error counter is
incremented by the circuit pack when it detects a CRC error. The test passes if
the value of the counter is 0 (that is, the error is cleared). If the counter is
non-zero, the test fails, and the value of the counter is displayed in the Error
Code field.
2012 ABORT Internal system error
2100 ABORT Could not allocate the necessary resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
2103 ABORT The system could not make the conference connection for the test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1, 2 FAIL The TDM Looparound failed on one of the channels.
■ Error Code 1 — TDM Loop Around Test failed on B1.
■ Error Code 2 — TDM Loop Around Test failed on B2.
7, 8 FAIL The Conference Circuit Tests failed on a B-channel.
■ Error Code 7 — test failed on B1
■ Error Code 8 — test failed on B2.
1. If the test fails repeatedly, attempt to reset the circuit pack with the
busyout board PCSS and the reset board PCSS commands if the
other ports on the board are not in use.
2. If the test fails again, replace the circuit pack.
PASS The BRI Port Local TDM Loop Around Test passed.
