b. This error type indicates that the circuit pack has been removed or has
been insane for more than 11 minutes. To clear the error, replace or
reinsert the circuit pack.
c. This error occurs when the EPF Status Inquiry fails due to an overcurrent
condition or when the BRI-LINE circuit pack detects that the EPF is in an
over current condition. The aux data field contains one of the following
values:
■ blank - this indicates that the EPF Status Inquiry failed due to an
overcurrent condition.
■ 40988 - this indicates that the BRI-LINE circuit pack has detected
an overcurrent condition and has turned the EPF off.
Execute the Short Test Sequence and see the repair procedures for Test
#622.
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.
