■ 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 Control
(PKT-CTRL) circuit pack 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.
Error Log Entries and Test to Clear Values
NOTE:
For PKT-BUS, an ON-BOARD alarm indicates a problem with the Packet
Bus itself.
1. Run the Short Test Sequence first. If all tests pass, run the Long Test Sequence. Refer to the
appropriate test description and follow the recommended procedures.
