Receive FIFO Overflow Error
Counter Test (#625)
This test is non-destructive.
This test reads and clears the BRI port’s Receive FIFO Overflow error counter
maintained on the TBRI-BD circuit pack. This counter is incremented by the circuit
pack when it detects an overflow of its receive buffers. The test passes if the value
of the counter is 0 (that is, the error is cleared). If the counter is non-zero, the test
fails, and the value of the counter is displayed in the Error Code field.
This error can occur if signaling frames are being received from the Packet Bus at
a rate sufficient to overflow the receive buffers on the circuit pack for a port OR if a
hardware fault is causing the receive buffers not to be emptied properly by the
circuit pack. This test is useful for verifying the repair of the problem.

Code Test
Result Description/Recommendation
2000 ABORT Response to the test was not received from the circuit pack
within the allowable time period.
1. If the test aborts repeatedly a maximum of 5 times, reset
the circuit pack with the busyout board PCSS and reset
board PCSS commands.
2. If the test aborts again, replace the circuit pack.
2012 ABORT Internal system error
2100 ABORT Could not allocate the necessary system resources to run this
test.
1. Retry the command at 1-minute intervals a maximum of 5
times.
value FAIL The TBRI-BD circuit pack is still detecting errors of this type.
The Error Code field contains the value of this counter.
1. Retry the command at 1-minute intervals a maximum of 5
times.
2. If the test continues to fail, run the Long Test Sequence
and pay particular attention to the Looparound Tests (#618
and #619). See the repair procedures for the executed test
if it fails. Otherwise, go to the next step.
3. Replace the circuit pack.
PASS The Receive FIFO Overflow error counter was read correctly
and has a value of 0.
