Invalid LAPD Frame Error Counter Test (#597)
This test is non-destructive.
CLAN detects invalid frames when it receives
■a frame with a CRC error
■an unrecognizable frame
■a recognizable frame in an unexpected state
When the CLAN circuit pack d etects an invalid LAPD frame, it inc rements the
Invalid LAPD Frame error counter. This test reads and c lears the counter, and
verifies the repair of the problem.
Errors may indicate a
■circuit pack problem
■packet bus problem
■problem with another circ uit pack on the bus
