ABSTRACT:
A module incorporating a single conductive line having in series a high resistance and a gas tube arcing device. The module includes means for interconnecting the same across the tip and ring circuits at a building entrance terminal to place on the line the equivalent of approximately ten percent of a normal alternating current ringer load. In the absence of a connected telephone set on the premises, the phantom ringer operates at 100 volts peak, and cuts off at 60 volts peak. Thus it poses no load during normal on hook and off hook operating conditions.
