D-20,732 CARRIER SUBSCRIBER TELEPHONE STATION TERMINAL LOOP CURRENT BOOSTER by James A. Stewart ABSTRACT OF THE DISCLOSURE The local battery and elements of a booster circuit of the energy storage-energy discharge type of swinging choke power converter are connected in series in the subscribers loop of a carrier subscriber station terminal. A smoothing capacitor is connected across the battery and booster circuit elements for providing a loop voltage that may be greater than a local battery voltage where a subscriber TOUCH-TONE? telephone set is off-hook and sending calling signals. Current in the circuit elements is monitored for controlling the duration of the portion of a cycle of operation of the converter during which energy is stored by the choke and, thus, maximum current drain from the battery. In an alternate embodiment, the smoothing capacitor is connected across only circuit elements.
