Receive FIFO Overflow Error Counter Test (#625)
This test reads and clears the BRI port’s Receive FIFO Overflow error counter
maintained on the BRI-LINE 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.

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 five times, reset the circuit
pack via 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 necessary system resources to run test.
1. Retry the command at one-minute intervals a maximum of five times.
2. If the test continues to fail, escalate the problem.
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 one-minute intervals a maximum of five times.
2. If the test continues to fail, review the results of other tests in the Long
Test Sequence. Pay particular attention to the results of the Level 1
Status Inquiry test. Follow repair procedures for any of the executed
tests if they fail. Otherwise, go to the next step.
3. If the tests for the endpoints or adjunct pass and the Layer 1
Transmission Error Counter Test continues to fail, check the wiring to the
endpoints or adjunct. If the wiring appears to be fine, escalate the
problem.
PASS The Layer 1 Transmission error counter was read correctly and has a value
of 0.
