A subscriber line interface circuit apparatus includes a signal processor having sense inputs for sensed tip and ring signals of a subscriber loop. The signal processor generates linefeed driver control signals in response to the sensed signals. A linefeed driver provides the sensed tip and ring signals. The linefeed driver drives the subscriber loop in accordance with the linefeed driver control signals.
