Invalid LAPD Frame Error Counter Test (#597)
This test is non-destructive.
The VAL circuit pack detects invalid frames when it receives
■ a frame with a CRC error
■ an unrecognizable frame
■ a recognizable frame in an unexpected state
When the VAL circuit pack detects an invalid LAPD frame, it increments the
Invalid LAPD Frame error counter. This test reads and clears the counter, and
verifies the repair of the problem.
Errors can indicate a
■ circuit pack problem
■ packet bus problem
■ problem with another circuit pack on the bus
