  • Patent number: 4071711
    Abstract: This invention relates to a multi-point information distribution system useful for telephone service, data connecting systems and other applications which permits a central station to service a plurality of outlying stations, through transmission media such as radio waves or wire cables, in privacy and using only one transmitting medium such as a first transmitting carrier frequency and one separate receiving medium such as a different receiving carrier frequency. The transmission media couples selected input connection points to selected terminating circuit devices one at a time. In accordance with the invention, the content on input connecting ports from a community dial office or other central system is time sampled at the central station which then transmits a sequentially ordered sample stream. Each terminating circuit or device is adapted to receive the content of only one time slot, and to transmit only during a coordinated and synchronized time slot.
