ABSTRACT:
A subscriber line interface circuit apparatus includes driver circuitry for combining and driving a downstream voice signal and a downstream data signal onto a subscriber line. Receiver circuitry receives and separates an upstream signal from the subscriber line into an upstream voice signal and an upstream data signal. The driver and receiver circuitry reside on a common integrated circuit die.
