| 1. An apparatus for providing a data interface to an AC powerline through a standard light bulb socket, comprising:
a data terminal device for coupling to an AC power line and processing data communicated along the AC power line; and
a data interface for coupling the data terminal device to the AC power line via a standard medium lamp base, comprising:
a frame;
a standard medium lamp base supported by the frame and for connecting to a branch circuit of the AC power line;
an electrical device having signal terminals and supported by the frame;
electrical circuitry having a first input and a first output, the first output coupled to the signal terminals for driving
the electrical device; and
a data receiver having a first input for receiving both AC power and a data signal from the AC power line, the first input
coupled to the lamp base, and a first output coupled to the first input of the electrical circuitry.
