System for coordination of electronic devices

Abstract

A system provides for the coordination of caller ID devices connected to a common telephone line and additionally may provide control of a number of electronic appliances within a home or building. Within a home or building, caller ID devices as well as a number of electronic appliances receive electrical energy through the electronic power lines. Each of the caller ID devices includes a processor which allows the transmission of control signals over the power lines in order that all caller ID devices on the same telephone line can be synchronized. This system can be further expanded to include a home controller which, via the power lines controls the operation of the electronic appliances. The home controller is connected to the common telephone line, and may download information and generate the appropriate command signals to control remotely located appliances.
