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 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 may indicate a
■ circuit pack problem
■ packet bus problem
■ problem with another circuit pack on the bus
1-10 FAIL Circuit pack detects overflow errors. The error code indicates the value of the
on-board error counter.
1. Retry the command at 1-minute intervals, up to 5 times.
2. If the test continues to fail, execute the Packet Interface Test (#598) (test
board UUCSS).
3. If Packet Interface Test (#598) fails, refer to Packet Bus repair procedures.
