  • Patent number: 4367548
    Abstract: In order to provide multiple services to a subscriber from a telephone central office, receiving and transmitting cables, preferably each being a single fiber optic strand, are coupled between the subscriber and the central office. Multiple signals, such as telephone signals, television signals, digital data, and FM radio signals are multiplexed onto the receiving cable. These signals are demultiplexed at the subscriber station to allow individual utilization of the services by the subscriber. Control of the services is allowed by transmitting control signals such as telephone control signals and television and FM radio channel selection signals over the transmitting cable, along with the telephone conversations and data. Further, alarm signals can be sent over the respective cables for purposes of monitoring fire, health, and security.
