Abstract
A system is provided for communicating between terminal units joined on a power distribution network. The terminal units in the system are capable of interfacing with external devices to which they are attached, of communicating with other terminal units, and of functioning as repeater units. When a message is received by a terminal unit, it determines whether the message is intended for itself or for another terminal unit. If it is intended for another terminal unit, it amplifies and retransmits the message. The system also includes means for determining the shortest communication path between one unit and an intended recipient terminal unit. When a previously established communication route is no longer effective, the system automatically determines a new communication route.
