NETWORK FOR TELEPHONY AND DATA COMMUNICATION
First Claim
1. A system for coupling a first data unit in a building to a Wide Area Network (WAN) external to the building over a home network based on a telephone wire pair, the system comprising:
- a telephone wire pair installed at least in part in walls of the building, the telephone wire pair being connected for carrying bi-directional digital data in a digital data frequency band distinct from, and higher than, an analog telephone frequency band;
a first device for coupling between the telephone wire pair and the WAN, said first device comprising;
a port for coupling to the WAN for communication with a location external to the building;
a first modem coupled to said port for transmitting digital data to, and receiving digital data from, the WAN;
a first telephone connector for connecting to said telephone wire pair;
a second modem coupled to said first telephone connector for transmitting the digital data to, and receiving the digital data from, the telephone wire pair; and
a high pass filter coupled between said second modem and said first telephone connector for substantially passing signals in the digital data frequency band, wherein said first device is operative to pass bi-directional digital data between the WAN and said telephone wire pair; and
a second device for coupling the first data unit to said telephone wire pair, said second device comprising, in a single enclosure;
a second telephone connector for connecting to said telephone wire pair;
a third modem coupled to said second telephone connector for transmitting digital data to, and receiving digital data from, said second modem over said telephone wire pair;
a high pass filter coupled between said third modem and said second telephone connector for substantially passing signals in the digital data frequency band; and
a data connector coupled to said third modem for connecting to the first data unit,wherein said second device is operative to pass bi-directional digital data between the first data unit and said telephone wire pair.

Abstract
A service outlet for coupling a data unit to a wired digital data signal and for coupling a service unit to an analog service signal, for use with a service wire pair installed in walls of a building, the service wire pair concurrently carrying a wired bi-directional digital data signal and an analog service signal carried over a service signal frequency band, using frequency division multiplexing, wherein the wired digital data signal is carried over a frequency band distinct from the service signal frequency band. The outlet has a single enclosure and, within the enclosure: a wiring connector; first and second filters coupled to the wiring connector; a service connector coupled to the first filter and connectable to the service unit for coupling the service unit to the analog service signal; a service wiring modem coupled to the second filter; and a power supply coupled to the service wiring modem.
