Abstract: A PABX telephone interfaced cable television system especially useful in hotels and motels for distributing free and premium program channels via a coaxial cable television signal distribution network to one or more subscriber terminals and associated television sets, includes a remotely tuned R.F. signal converter connected to each subscriber's television set and the coaxial cable network for enabling the set to receive a subscriber selected one of the premium channels not normally receivable by the set. The converter is automatically tuned to the selected premium channel by enabling signals transmitted from a central station to the subscriber's converter via the PABX telephone network and the subscriber's telephone. The request for a premium channel is made from the subscriber's telephone by the dialing of a predetermined sequence of digits peculiar to the requesting subscriber and the desired premium channel selected for viewing.
