1. A utility meter, said utility meter communicatively coupled to an automatic meter reading (AMR) network and a local area network (LAN), said utility meter comprising:
- (a) a radio frequency (RF) transceiver;
(b) a telephone modem;
(c) a LAN transceiver;
(d) a controller operatively coupled to said RF transceiver, modem and LAN transceiver;
(e) metering means operatively coupled to said controller; and
(f) a plurality of communications protocols for facilitating communications between said AMR network, LAN and utility meter;
whereby said utility meter is operable to function as a communications interface between said AMR network and said LAN.

Abstract
A solid state electrical meter incorporates the ability to support two-way radio, dialback telephone and CEBus personal LAN. These three communications media require different protocols to meet their respective requirements. Embedding multiple protocols within the meter controller makes the device extremely flexible for current and future applications.
