Abstract
A telephone line interface includes a ring detect circuit for activating a RF transceiver and thereby notifying the RF headset of a ringing condition on a telephone line. A wire conversion circuit separates transmit voice signals from receive voice signals and provides the separated voice signals to the RF transceiver. A firmware allows the electronic hook switch to go off hook only when the line is ringing or only when the line is off hook.
