The Maintenance/Test Packet Bus Port is a port (always Port #4) on the TN771D
(or later vintage) Maintenance/Test circuit pack, which is required for
G3iV1.1-286 or G3iV2-386. The Packet Bus port provides the following Packet
Bus maintenance functions:

Bus maintenance functions:
■
Packet Bus fault detection - the ability to detect faults (for example, shorts,
open leads) on the Packet Bus autonomously (that is, without SPE
involvement).

■
Packet Bus reconfiguration - the ability to swap faulty leads with spare
leads autonomously so that the Packet Bus remains operational. This is
accomplished by sending messages to all Packet circuit packs [for
example, ISDN-BRI (TN556)] telling them which spare leads to use on the
Packet Bus.

When Maintenance/Test Packet Bus Port maintenance determines that the
Packet Bus Port is defective, the Packet Bus fault detection and Packet Bus
reconfiguration functions provided by the port are turned off.

Maintenance/Test Packet Bus Port maintenance interacts with Packet Bus
maintenance. Therefore, there may be alarms on the Packet Bus when there is a
fault on the Maintenance/Test Packet Bus Port. Refer to PKT-BUS (Packet Bus)
Maintenance documentation for further information.
