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 empti ed properly by
the circuit pac k. This test is useful for verifying the repair of the prob lem.

Error
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 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 pac k.
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 Erro r Counter Test continues to fail, check the wiring to the
endpoints or adjunct. If the wiring appears to be fine, esc alate the
problem.
PASS The Layer 1 Transmission error counter was read correctly and has a value
of 0.
