description This invention relates to the field of telephony, and in particular to a method and apparatus for connecting broadband voice and data signals to telephone systems. The invention is suitable for, but not limited to, interfacing a DSL analog front end circuit to a subscriber line in the presence of a voice band (DC-4000 Hz) signal. DSL (Digital Subscriber Line) is a service that permits broadband data signals to be superimposed on local subscriber loops. 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.
