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.
