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.
