1. An intelligent device for a power line communication system, comprising:
- a memory storing information uniquely specifying the identity of the intelligent device and an interface for data communication with a power line; and
a configuration processing arrangement to perform a configuration process, which includes using said interface to perform the following;
a) detecting data of a first data type through the interface and in response thereto extracting from the data of a first data type and recording in memory identity information for the source of the data of a first data type and generating on said interface data of a second data type that has as a destination address the source of the data of a first data type and includes the information specifying the identity of the intelligent device;
b) detecting data of a second data type that have the intelligent device as a destination address and in response thereto extracting from the data of a second data type and recording in memory the identity of the source of the data of a second data type and generating on said interface data of a third data type that includes information identifying the source of the data of a second data type and the information specifying the identity of the intelligent device; and
c) detecting data of a third data type and in response extract there from and recording in memory information identifying the source of the data of a third data type associated with the information identifying the source of the data of a second data type included in the data of a third data type and generating data on said interface containing the information identifying the source of the data of a third data type, the information identifying the source of the data of a second data type included in the data of a third data type and the information specifying the intelligent device'"'"'s identity.

Abstract
A power line communication system including a plurality of intelligent devices in communication with a power line and operable to monitor energy usage at a site and communicate usage data onto the power line, and a controller also in communication with the power line, wherein each intelligent device maintains a routing table identifying a first set of other intelligent devices downstream of it relative to the controller that it can communicate with directly and identifying a second set of other intelligent devices downstream of it relative to the controller that it can communicate with through one or more of the first set of other intelligent devices.
