Power line communications interface to indoor subscriber
First Claim
1. An interface for partitioning and distributing deliverables borne by an outdoors power carrier to an indoor communications network, and wherein said interface connects between said indoor network and said outdoor power carrier bi-directionally, comprising:
- a PLC (power lines communications) interface, connected in parallel to said power carrier for downloading communication signals from said power carrier, and for loading upstream communications signals;
a connection between said PLC interface and said indoor communications network;
a block band—
low pass filter for directing upstream and downstream communications signals into said PLC interface, and a pre-filter for preconditioning said communications signals.

Abstract
An interface device for partitioning and deliverables from a power line to a home communications network. The deliverables include both electric power and communications signals. The communications signals, such as data signals, are delivered through a LAN to end-points. The device of the invention is bidirectional as it provides both upstream and downstream communications traffic. The interface can also furnish Information to the power meter and obtain information from it.

4. A method for bi-directionally interfacing between PLC (power line communications) service and home communications network, comprising:
-
separating between current and communications signals flow by employing a PLC interface connected in parallel to the power carrier;
demodulating and modulating incoming and outgoing communications signals respectively;
compatibly connecting between said PLC service and said home communications network, and connecting end—
points of said home communications network to said PLC communications service. - View Dependent Claims (5, 6)
