Patent ID: 7034663

Claim:
A method of controlling, in an electric power distribution system comprised of multiple sets of premises power distribution lines, communication of power line communication devices associated with one set of premises power distribution lines with power line communication devices associated with another, different set of premises power distribution lines, the method comprising: assigning an identification address for each of multiple power line communication devices associated with a set of premises power distribution lines, the address being for use by the power line communication devices when messages are transmitted over the set of premises power distribution lines; designating one of the multiple power line communication devices as a master power line communication device and the remaining ones of the power line communication devices as slave power line communication devices; activating an enrollment mode for the master power line communication device; establishing for the master power line communication device a master code to be used in identifying the multiple power line communication devices as members of a system of power line communication devices associated with the set of premises power distribution lines; causing the master power line communication device to receive and store the identification address for at least one of the slave power line communication devices and thereby enroll the slave power line communication device as one member slave power line communication device of the system; and causing the master power line communication device to transmit the master code to said one member power line communication device to associate the master power line communication device with said one member power line communication device; thereby, upon establishment in the master power line communication device of an association of the identification addresses of the member slave power line communication devices, identifying communications among the member power line communication devices such that said communications among the member power line communication devices can be distinguished from communications among power line communication devices associated with a separate, different set of premises power distribution lines.
