Receive FIFO Overflow Error Counter Test (#625)
This test reads and clears the BRI port’s Rec eive FIFO Overflow error counter
maintained on the BRI-LINE circuit pac k. This counter is incremented b y the
circuit pack when it detects an overflow of its rec eive buffers. The test passes if
the value of the counter is 0 (that is, the error is c leared). If the counter is
non-zero, the test fails, and the value of the counter is di splayed in the Error Code
field.
This error can occur if signaling frames are being recei ved from the Packet Bus
at a rate sufficient to overflow the receive buffers on the c ircuit pack for a p ort OR
if a hardware fault is causing the rec eive buffers not to be emp tied properly b y
the circuit pac k. This test is useful for verifying the repair of the p roblem.

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 via the busyout board PCSS and reset board PCSS
commands.
2. If the test aborts again, replace the circuit p ack.
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 BRI-LINE 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 Loop Around 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.
