The Maintenance/Test packet bus port (M/T-PKT) is Port #4 on the TN771D Maintenance/Test
circuit pack. The packet bus port provides the following packet bus maintenance functions:
● Packet bus fault detection
The ability to detect faults (for example, shorts, open leads) on the packet bus
autonomously (i.e., without Communication Manager involvement).
● Packet bus re-configuration
The ability to swap faulty leads with spare leads autonomously so that the packet bus
remains operational. This is accomplished by sending a message to every circuit pack
using the packet bus (for example, TN556 ISDN-BRI), telling it which spare leads to use on
the bus.
M/T-PKT maintenance ensures that these maintenance functions are operating correctly. The
Maintenance/Test packet bus port is alarmed if maintenance determines that the port’s
maintenance functions are operating incorrectly.
When M/T-PKT maintenance determines that the packet bus port is defective, the packet bus
fault-detection and re-configuration functions provided by the port will be turned off.
M/T-PKT maintenance interacts with packet bus maintenance. Therefore, there may be alarms
on the packet bus when there is a fault on the M/T-PKT. For further information, refer to the
PKT-BUS MO’s section.
