An external plug-in module is inserted, or field retrofitted, between a validator and a phone chassis and incorporates circuitry to condition the coin signals generated by the validator. This signal conditioning eliminates the possibility of the chassis being improperly triggered and generating false coin tone signals during periods of interrupted power.
