ABSTRACT:
A telephone line interface and associated circuitry that may be implemented to simultaneously couple DC loop voltage, ring bursts, and caller-ID data to the phone line side of a DAA circuit through a single two wire resistively coupled interface. The interface and circuitry may be implemented to combine processing of the DC loop voltage and ring bursts into a single circuit, with processing of caller-ID data being performed separately.
