Telephone outlet for implementing a local area network over telephone lines and a local area network using such outlets
First Claim
1. A local area network within a building, for transporting data among a plurality of data devices, the local area network comprising:
- (a) at least two network outlets, each of said network outlets having;
i) at least one data interface connector and data interface circuitry coupled to said data interface connector and operative to establishing a data connection between a data device and said data interface connector;
ii) at least one standard telephone connector operative to supporting standard telephony service by connecting a standard telephone device;
iii) a splitter operative to separating telephony and data communications signals; and
iv) a coupler operative to combining telephony and data communications signals;
(b) at least one telephone line segment within the walls of the building, each said telephone line segment connecting at least two of said network outlets and having at least two conductors, said telephone line segment operative to concurrently transporting telephony and data communication signals; and
(c) at least one modem housed within each of said network outlets for establishing a data connection over said at least one telephone line segment, said at least one modem operative to transmitting and receiving signals over said telephone line segment, and coupled thereto.

Abstract
A local area network using the telephone wiring within a residence or other building simultaneously with telephony signals, with network outlets having telephone and data connectors allowing connection of Data Terminal Equipment to the network. The network outlets use high pass filters to access the high-frequency band across the media, whereas the standard telephone service uses low pass filters to access the low-frequency voice/analog telephony band across the same media. The high pass filters of the network outlets at each segment end are connected to modems or other Data Communication Equipment, thus supporting data communication networks of various topologies, including point-to-point topologies. The invention also contemplates a network outlet having a data interface connector for allowing connection of Data Terminal Equipment thereto and having a telephone connector for connecting a standard telephone thereto. A splitter is adapted to be connected to a telephone line for separating data and telephone signals transported on the telephone line, whilst a coupler is adapted to receive telephone and data signals and feeds a composite signal at an output thereof to the telephone line.
