2. Check all other circuit packs connected to the Packet bus in the
same cabinet. Packet Bus failures are likely to be caused by a
faulty circuit pack connected to the backplane or bent pins on the
back plane.
3. If steps 1 and 2 above do not clear the problem, execute the
test
packet-interface
command and follow repair procedures
described for Test #887.
s. Error 2561 indicates a Active-Standby Peer Link test failure indicating a
possible failure of the Packet Interface circuit pack on the active SPE or a
failure of the corresponding Packet Interface circuit pack on the standby
SPE. If the number of errors exceeds a defined threshold, a Minor alarm
will be raised. For more information, refer to the repair procedures of Test
#888.
t. Error 2817 indicates a Standby Packet Interface circuit pack Translation
RAM failure. A MINOR alarm is raised when there are 1 to 5 bad locations
and a MAJOR alarm is raised when there are 5 or more bad locations.
Execute the
test packet-interface
command and follow repair procedures
described for Test #887.
u. Errors 3074, 3073, and 3072 indicate PKT-INT Transmit Buffer Overflow,
which means that the number of transmit buffers required by software
exceeded the number available. A 3074 error is generated when the
PKINT sends an in-line hardware error to maintenance software indicating
transmit buffer overflow. As part of the background recovery action for this
error, maintenance software will automatically run the Maintenance
Looparound test (#886). If that test fails, maintenance software generates
error codes 3073 and 3072, and it requests a system WARM restart. If,
after the WARM restart, transmit buffer overflow errors continue to be
reported, maintenance software generates error code 100 and it resets the
PKT-INT. These errors may be the result of system overload due to a
problem with communication between the PKT-INT and the EPNs.
1. Check for errors logged against the Expansion Interface circuit
pack, the Switch Node Interface circuit pack, Packet Gateway
circuit pack, the Packet Data Line circuit packs associated with the
System Ports, BRI Line circuit packs and BRI endpoints, and the
Universal DS1 circuit packs supporting PRI service. Errors against
those components should be cleared first.
2. Enter the test packet-interface short command against the Packet
Interface circuit pack associated with the error. If the Maintenance
Looparound test (#886) test passes, the alarm will clear. If the test
fails, repeat the test 5 times. If it continues to fail, follow normal
escalation procedures.
v. Error 3329 indicates that the TDM clock has failed. The Tone Board should
have been alarmed (TONE-BD, TDM-CLK). Refer to TDM-CLK and/or
TONE-BD for further action. The Packet Interface circuit is taken out of
service when this failure occurs. Execute the reset packet-interface
command to bring the Packet Interface circuit back into service.
