p. Errors 3074, 3073, and 3072 indicate Packet Inter face Transmit Buffer
Overflow, which means that the number of transmit b uffers required by
software exceeded the numb er available. A 3074 error is gener ated when
the Packet Interface sends an in-line hardware error to maintenance
software indicating transmit b uffer overflow. As part of the bac kground
recovery action for this error, maintenanc e 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 th e result of system
overload due to a prob lem with communication b etween the Packet
Interface and the Packet Bus c ircuit packs.
1. Clear errors against any of these components fi rst:
■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 p rocedures.
q. Error 3329 indicates that the TDM clock has fai led (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 thi s failure occurs.
1. Execute the reset packet-interface command to bring the Packet
Interface back into s ervice.
r. Error 3585 indicates a Packet bus failure. Refer to the Packet Bus
maintenance documentatio n for further action.
s. Error 3841 indicates that the Packet Interface has rep orted a fatal fault
failure condition that may be caused by a Packet Bu s 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 Interfac e back into service (reset
packet-interface).
2. If Error Type 3585 has not been reported, enter the reset
packet-interface command and f ollow the repair steps assoc iated
with test #889.
