buffer overflow, it increments the error on the FIFO Overflow error counter. This
test reads and clears the counter.
If errors are: Then they may be due to:
Occasional Statistical buffer sizing
Persistent Circuit pack congestion that requires redistribution of traffic load

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 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 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 Packet Interface Test #598 (test board
UUCSS).
3. If Packet Interface Test #598 fails, see ‘‘PKT-BUS (Packet Bus)’’ on page
8-1230 for repair procedures.
PASS Circuit pack detects no errors.
