If the counter is non-zero, the test fails, and the value of the counter is displayed
in the

field.
Receive FIFO Overflow Error
Counter Test (#625)
This test is nondestructive. 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.

Result Description/ Recommendation
ANY FAIL This error occurs when a frame with a bad CRC is received over the
D-Channel by the BRI board. This error is reported on a per-port basis
when the counter goes over the threshold. This error is most likely due to a
problem with the wiring or interference on the wiring caused by a noise
source or no termination. It usually does not indicate a problem with the
circuit pack.
PASS The CRC error counter was read correctly and has a value of 0.
