Abstract
Simultaneous communication of data and voice on a common telephone line are provided between a customer location and a central switching location. At the customer location there may be provided a series of computers each having the LAN interface connected to a common data bus at the customer location with that bus connected to the telephone line. At the central switching station the telephone lines are connected to a central hub device which does not provide a data bus but connects to the Internet. High and low pass filters allow the data from the LAN interface from the voice from a telephone set to be communicated simultaneously on the common line. Equalization and pre distortion are provided to enhance transmission line distances.
