CLAN-BD (Control LAN Circuit Pack)
Invalid LAP-D Frame Error Counter Test (#597)
This test is nondestructive.
A C-LAN detects an invalid frame when it receives:
a frame with a CRC error
an unrecognizable frame
a recognizable frame in an unexpected state
When the C-LAN circuit pack detects an invalid LAP-D frame, it increments the
Invalid LAP-D 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

Error Test
Code Result Description / Recommendation
2000 ABORT Did not receive circuit pack test response within the allowable time period.
1. Retry command at 1-minute intervals up to 5 times.
2. If the problem persists, reset the circuit pack (reset board UUCSS).
3. If the problem persists, replace the circuit pack.
2100 ABORT Could not allocate the necessary system resources to run this test.
2500 ABORT Internal system error.
1. Retry the command at 1-minute intervals up to 5 times.
2. If the problem persists, escalate the problem.
1–10 FAIL The circuit pack detects LAP-D frame 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
3. If the Packet Interface test (#598) fails, see
PASS Circuit pack detects no errors.
