M/T-PKT (Maintenance/Test Packet
Bus Port)
The Maintenance/Test Packet Bus Port (M/T-PKT) is port number 4 on the TN771
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 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 [e.g., ISDN-BRI (TN556)] telling them
which spare leads to use on the Packet 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 Packet Bus 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. Refer to
PKT-BUS (Packet Bus) Maintenance documentation for further information.
