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

Result
Description/ Recommendation
2000
ABORT
Did not receive circuit pack test response within the allowable time period.
Retry command at 1-minute intervals, up to 5 times.
If the problem persists, reset the circuit pack (reset board UUCSS).
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.
Retry the command at 1-minute intervals, up to 5 times.
If the problem persists, escalate the problem.
1-10
FAIL
The circuit pack detects LAPD frame errors. The error code indicates the
value of the on-board error counter.
Retry the command at 1-minute intervals, up to 5 times.
If the test continues to fail, execute the Packet Interface Test (#598) (test
board UUCSS long).
If Packet Interface Test (#598) fails, see repair procedures for Test (#598).
PASS
Circuit pack detects no errors.
