1. A local area network comprising:
- a) two separate telephone networks, at least one of the networks coupled to a telephone line;
b) a telephone coupled to the network coupled to the telephone line and generating telephone signals;
c) a plurality of network computing devices, each of which is coupled to one of the telephone networks and each of which generates data signals; and
d) a coupling device coupled to each of the telephone networks and operating to pass data signals from one telephone network to the other telephone network and isolate telephone signals on one telephone network from the other telephone network.

Abstract
A local area data network includes two separate and unique twisted pair telephone networks joined by a coupler to form a common data network. The coupler operates to pass pulse position modulated data signals (PPM) and quadrature amplitude modulate (QAM) data signals between the telephone networks and isolate each plain old telephone service (POTS) signals on one telephone network from the other telephone network.

23. A coupling device for providing selective coupling between at least two individual telephone networks, the coupling device comprising:
-
a) a first set of terminals for connecting the coupling device to a first one of the at least two individual telephone networks;
b) a second set of terminals for connecting the coupling device to a second one of the at least two individual telephone networks; and
c) a filter operatively coupled to the first and second set of terminals and tuned to pass there between a predefined band of signal frequencies associated with network data communications and to block there between a predefined band of signal frequencies associated with audio communications. - View Dependent Claims (24, 25, 26, 27)
