3-903PKT-INT (Packet Interface)

p. Errors 3074, 3073, and 3072 indicate Packet Interface 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 Packet Interface 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 automatically runs the
Maintenance Looparound Test (#886). If that test fails, maintenance
software generates Error Types 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 Type 100
and resets the Packet Interface. These errors may be the result of system
overload due to a problem with communication between the Packet
Interface and the Packet Bus circuit packs.
1. Clear errors against any of these components first:
■ C-LAN circuit pack
■ BRI Line circuit pack and BRI endpoints
■ BRI Trunk circuit pack
■ the Universal DS1 circuit pack supporting PRI service
■ Media Processor circuit pack
■ MAPD circuit pack
2. Enter the
test packet-interface short
command against the Packet
Interface associated with the error. If the Maintenance Looparound
Test (#886) passes, the alarm clears.
3. If the test fails, repeat the test 5 times.
4. If it continues to fail, follow normal escalation procedures.
q. Error 3329 indicates that the TDM clock has failed (TONE-BD and
TDM-CLK alarms). Refer to TDM-CLK and/or TONE-BD for further action.
The Packet Interface is taken out of service when this failure occurs.
1. Execute the
reset packet-interface
command to bring the Packet
Interface back into service.
r. Error 3585 indicates a Packet bus failure. Refer to the Packet Bus
maintenance documentation for further action.
s. Error 3841 indicates that the Packet Interface has reported a fatal fault
failure condition that may be caused by a Packet Bus failure.
1. If Error Type 3585 has also been reported, refer to PKT (Packet
Bus) maintenance. After the Packet Bus failure has been corrected,
bring the Packet Interface back into service (
reset
packet-interface
).
2. If Error Type 3585 has not been reported, enter the
reset
packet-interface
command and follow the repair steps associated
with test #889.
