Abstract: A telecommunication interface integrates DSL and POTS components in a manner which effectively separates their bandwidth requirements from their power requirements. This is accomplished by powering the tip path and ring path amplifiers with a pair of transformer-coupled floating power supply-sourced voltages, and referencing respective like polarity inputs of the amplifiers to a differential voltage pair that is used to operate the subscriber loop, including providing loop current and controllably applying a ringing voltage to the POTS line.
