M/T-PKT (Maintenance/Test Packet
Bus Port)
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 (e.g., shorts, open leads) on the packet bus
autonomously (i.e., without Avaya MultiVantage™ software 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 a
message to every circuit pack using the packet bus (e.g., 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 -reconfiguration 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.
