10-1264 Issue 4 May 2002
■ A Packet Bus failure in the Processor Port Network (PPN) causes Packet
traffic (ISDN-BRI, ASAI) in the Expansion Port Networks (EPNs) to fail,
even though there is no Packet Bus failure in the EPN. This is true because
all Packet traffic requires communication with the Packet Interface 1A2 on
the NetPkt circuit pack (R7si and later systems) or the Packet Control
(PKT-CTRL) circuit pack (pre-R7si systems) in the PPN. Due to this
requirement, a PPN Packet Bus failure must be investigated first whenever
Packet Bus failures occur in multiple port networks.

NOTE:
For PKT-BUS, an ON-BOARD alarm indicates a problem with the Packet
Bus itself.
