when the Packet Bus transmit buffers overflow. This cond ition probably
indicates a hardware problem. The BRI-PORT Alarm Level for the error
with Aux Data 46222 is ‘‘MIN/WRN,’’ and the
ABRI-PO RT/ATT-PORT/LG ATE-PT/ATTE-PT Ala rm Le vel is
‘‘MAJ/MIN/WNR.’’ With Aux Data 0, this error occurs whenever the Packet
Bus transmit FIFO buffers ov erflow. This condition can be caused by an
on-board hardware prob lem as well as by problems on the Pac ket Bus
that disrupt the BRI circuit p ack’s ability to transmit d ata onto the Packet
Bus. Use troubleshooting proc edures for both on-board hardware
problems and p otential off-board Packet Bus prob lems. See the
‘‘PKT-BUS (Packet Bus)’’ section in this chapter as well as ‘‘Pack e t Bus
Fault Isolation and Repair’’ in Chapter 5, ‘‘Alarms, Errors, and
Troubleshooting’’ for more details on Packet Bus troubleshooting
procedures. The BRI-PORT Alarm Level for the error with Aux Data 0 is
‘‘MINOR,’’ and the ABRI-PORT/A TT-PORT/LGATE-PT/ATTE-P T Alarm Level
is ‘‘MAJOR.’’
e. This error occurs when the NPE Crosstalk Test (#617) fails. Run the Long
Test Sequence and pay particular attenti on to the results of Test #617.
f. This error occurs when broadc ast signaling links associated with this port
have too much link establishment related traffic. This could occ ur if an
endpoint on this por t is sending link establishment traffic on a port level
broadcast link or if there are Level 1 p roblems on the port. Check the error
logs for Level 1 errors. If Level 1 prob lems exist, follow the repair
procedures listed for tes t #621. Software will suspend activity to this p ort
for 75 minutes when the port is alarmed d ue to this error (note that service
suspension does not oc cur if the port is an
ABRI-PORT/LGATE-PT/ATTE-PT/ATT-PORT). If this problem persists,
replace the endpoint or endpoints associated wit h this port. If replacing
the endpoints does not fix the problem, follow normal escalation
procedures.
g. This error occurs when the por t receives an invalid frame over the
D-channel. When CRC errors exceed five within 15 minutes, the p ort is
taken out of service for five second s. If five more CRC errors are received
within 15 minutes of the first set of five errors, the port is take n out of
service for one minute. If five more CRC errors are received within 15
minutes of the last five, the port is taken out of servic e for 15 minutes.
This error is most likely due to a problem with the wiring to the set or
adjunct, interference on the wiring due to a noise source, or no termination
(an open circuit). It usually d oes not indicate a prob lem with the circuit
pack.
■Check the wiring to the end points or the adjunct.
■If the problem persists, rep lace the endpoints or adj uncts, or
escalate the problem.
h. This error occurs when the BRI Port Local TDM Loop Around Test (#619)
fails. Run the Long Test Sequence and pay partic ular attention to the
results of Test #619.
