The invention provides a central location for receiving voice, video, and data signals. A plurality of user locations are connected to a single central location. Each user location is connected to the central location by means of a single coax wire, and voice, video and data are all multiplexed over the coax, so that increased data capabilities can be added to individual user locations without the need to rewire existing user locations. This is particularly advantageous where such user locations have already been wired, and where rewiring would be a difficult and expensive process, e.g., passenger cabins on board a cruise ship.
