First Ring Suppressor Device



Telephone First-Ring Suppressor Device

Theta Engineering developed a novel device which, when inserted into a phone line, suppresses the first ring of an incoming call. About the size of a postage stamp and embeddable in an ordinary telephone line splitter, this device incorporates a Microchip microcontroller that is powered by the ring energy itself. All aspects of the development of this product were handled at Theta Engineering.
