ABSTRACT:
A subscriber line interface circuit ("SLIC") for a telecommunications device powered from a single power source and using a voltage regulator to limit the voltage across the terminals of the telecommunications device to a predetermined value below the industry standard voltage limits. The SLIC selectively enables or disables the speech amplifiers responsive to an external control signal that is independent of the on-hook/off- hook status of the telecommunications device. The SLIC provides a ringing signal and/or a caller identification signal through the speech amplifiers to the telecommunications device while the telecommunications device is on-hook.
