d. This error indicates that the circuit pack is having problems transmitting
data to the Packet Bus, thus affecting the conveyance of signaling
information over the D-channel. With Aux Data 46222, this error occurs
when the Packet Bus transmit buffers overflow. This condition probably
indicates a hardware problem. The BRI-PORT Alarm Level for the error
with Aux Data 46222 is "MIN/WRN," and the
ABRI-PORT/ATT-PORT/LGATE-PT/ATTE-PT Alarm Level is
"MAJ/MIN/WNR." With Aux Data 0, this error occurs whenever the Packet
Bus transmit FIFO buffers overflow. This condition can be caused by an
on-board hardware problem as well as by problems on the Packet Bus that
disrupt the BRI circuit pack's ability to transmit data onto the Packet Bus.
Use troubleshooting procedures for both on-board hardware problems and
potential off-board Packet Bus problems. See the "PKT-BUS (Packet Bus)"
Maintenance section in this chapter as well as Chapter 9, "Packet Bus
Fault Isolation and Correction" 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/ATT-PORT/LGATE-PT/ATTE-PT Alarm Level is "MAJOR."
e. This error occurs when the NPE Crosstalk Test (#617) fails. Run the Long
Test Sequence, and pay particular attention to the results of Test #617.
f. This error occurs when broadcast signaling links associated with this port
have too much link establishment related traffic. This could occur if an
endpoint on this port is sending link establishment traffic on a port level
broadcast link, or if there are Level 1 problems on the port. Check the error
logs for Level 1 errors. If Level 1 problems exist, follow the repair
procedures listed for test #621. Software will suspend activity to this port
for 75 minutes when the port is alarmed due to this error (note that service
suspension does not occur if the port is an
ABRI-PORT/LGATE-PT/ATTE-PT/ATT-PORT). If this problem persists,
replace the endpoint or endpoints associated with this port. If replacing the
endpoints does not fix the problem, follow normal escalation procedures.
g. This error occurs when the port receives an invalid frame over the
D-channel. When CRC errors exceed five within 15 minutes, the port is
taken out of service for five seconds. If five more CRC errors are received
within 15 minutes of the first set of five errors, the port is taken 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 service 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 does not indicate a problem with the circuit
pack.
10-272 Issue 4 May 2002
Check the wiring to the endpoints or the adjunct.
If the problem persists, replace the endpoints or adjuncts, or
escalate the problem.
