  • Filter circuit receiving upstream signals for use in a CATV network
    Patent number: 5126840
    Abstract: A two-way CATV network which in the preferred embodiment uses gating upstream narrowband filters in the distribution lines and/or trunks to substantially reduce upstream noise gathering. The filters sense the upstream signal energy and open in the event the energy exceeds a predetermined threshold.
    Type: Grant
    Filed: October 25, 1990
    Date of Patent: June 30, 1992
    Assignee: Videotron LTEE
    Inventors: Michel Dufresne, Samir Sammoun, Alain Tessier, Fracois Methot
  • CATV network with addressable filters receiving MSK upstream signals
    Patent number: 4982440
    Abstract: A two-way CATV network which in the preferred embodiment uses gating upstream narrowband filters in the distribution lines and/or trunks to substantially reduce upstream noise gathering. The filters sense the upstream signal energy and open in the event the energy exceeds a predetermined threshold.
    Type: Grant
    Filed: April 21, 1989
    Date of Patent: January 1, 1991

  • CATV subscriber terminal transmission control
    Patent number: 4920533
    Abstract: A bidirectional cable communication system comprising a head and, a bidirectional transmission network connected to the head end for transmitting signals downstream from the head end to a plurality of subscriber stations and for transmitting data signals upstream to the head end from the subscriber stations, means at the head end for detecting collisions between signals received from the subscriber stations and for generating a collision signal, means at the head end for transmitting downstream on the transmission system status bits of data signal indicative of the collision, whereby upon detection thereof by a subscriber station it can be enabled to cease transmission.
