  • Method and apparatus for connecting broadband voice and data signals to telephone systems
    Patent number: 7106855
    Abstract: A system for use in connecting broadband voice and data signals to communications systems such as the telephone system. Due to the low pass filtering characteristics of a standard twisted pair used in conventional telephone access loops data band signals are attenuated more than voice band signals. The present invention provides apparatus and methods for interfacing data and voice band signals to a common communications medium, such as a twisted pair, while significantly reducing the influence of one frequency band on the other.
    Type: Grant

  • Method and apparatus for connecting broadband voice and data signals to telephone systems
    Patent number: 6674845
    Abstract: In an apparatus for supplying a tip and ring telephone line with voice band and broadband signals, a first pair of drivers supply at least DC signals to the respective tip and ring line components, and a second pair of drivers supply broadband signals to the tip and ring line components. Feed components combine the outputs of said respective drivers for the respective tip and ring components of the telephone line.
