    Abstract: A subscriber's telephone system is presented that includes at least one driver circuit connected to Tip and Ring terminals. An additional network is connected between an output of the driver circuit and the Ring terminal. This additional network includes a suitably dimensioned capacitor and a diode limiter connected in parallel with each other to minimize the overall voltage while maintaining a desired battery mean value.

    Abstract: A telephone interface circuit with impedance termination during call pauses, comprising: a first and a second terminals of a telephone line; a branch connected to the first terminal, across a decoupling capacitor, and to the second terminal, and furthermore comprising an intersection node; the branch comprises a first switch and a first impedance resistor between the first terminal and the intersection node and a second switch and a second impedance resistor between the second terminal and the intersection node; the intersection node is connected to the ground across a third switch; the first switch, the second switch, and the third switch are controlled by a control unit by means of a first, a second and a third control lines respectively. The circuit furthermore comprises a ring signal detector that is connected to a microprocessor unit capable of activating the control unit in the interval in which the circuit must be terminated for CLID (Calling Line IDentification) transmission.
