System and method for a subscriber-powered network element
First Claim
1. A subscriber terminal for use in a wide area network (WAN), the subscriber terminal comprising:
- a power source disposed to having a first current and a first voltage that provides an electrical power having a second current and a second voltage for transmission across at least one WAN transmission line;
at least one WAN communication device that transmits a data signal at a first frequency and receives a message regarding the electrical power at a second frequency; and
at least one electrical coupling device electrically coupled to the power source and electrically coupled to the at least one WAN communication device, wherein the at least one electrical coupling device couples the electrical power and the data signal for transmission onto the at least one WAN transmission line and wherein the at least one electrical coupling device receives the message regarding the electrical power and provides the message to the at least one WAN communication device.

Abstract
A system for powering a network element of a fiber optic wide area network is disclosed. When communication data is transferred between a central office (CO) and a subscriber terminal using a network element to convert optical to electrical (O-E) and electrical to optical (E-O) signals between a fiber from the central office and twisted wire pair, coaxial cable or Ethernet cable transmission lines from the subscriber terminal, techniques related to local powering of a network element or drop site by the subscriber terminal or subscriber premise remote powering device are provided. Certain advantages and/or benefits are achieved using the present invention, such as freedom from any requirement for additional meter installations or meter connection charges and does not require a separate power network.
