PKT-BUS (Packet Bus)
● Certain catastrophic packet bus faults have an effect on maintenance software activities
relating to packet circuit packs, ports, and endpoints:
- Packet circuit pack (BRI-BD, UDS1-BD) inline errors indicating possible Packet Bus
test failures are logged in the error log, but are not acted upon.
- Port-level (BRI-PORT, ABRI-PORT) inline errors on Packet circuit packs which
indicate possible Packet Bus failures are not logged or acted upon.
- Circuit pack and port inline errors that are not relevant to the Packet Bus, or that
indicate a circuit pack failure, are acted upon in the normal fashion.
- Periodic and scheduled background maintenance are not affected.
- Foreground maintenance (for example, a test board command executed at a
terminal) is not affected.
The actions in the previous list serve to reduce the system load, which could become
excessive if many MOs are affected by a packet bus failure. However, such an excessive
load should in no way impede the isolation and the correction of the faults.
When the above actions are implemented, Error Type 3329 is logged against PKT-BUS,
and a Warning alarm is raised. Other Packet Bus errors may raise more severe alarms,
thereby overriding the Warning alarm.
● S8700-series Fiber-PNC: Since all packet traffic requires communication with the IPSI’s
PKT-INT circuit in an IPSI connected PN, a PKT-BUS failure in the IPSI connected PN
causes packet traffic in this PN, and every PN controlled by the IPSI connected PN, to fail.
In the S8700 Fiber-PNC configuration where some PNs are non IPSI connected, an IPSI
connected PN PKT-BUS fault should be investigated first whenever PKT-BUS problems
occur in multiple PNs.
