hybrid circuit for intervention and exploration for electronic recording of telephone exchange, ectromecaniques

摘要

A hybrid circuit for an electric operating and scanning interface, applicable to electronic recorders of electromechanical telephone stations, consisting of a hybrid circuit utilized as a union interface between an electronic system carrying out the modernization of a station and the own station, and controlling tension and current parameters on different elements and situations of the station by means of an energetic transmission to same, being capable of scanning the situation under which the elements, operated by it, stand, being configured as input and output when injecting or taking out current and tension from the elements on which it acts, and allowing the current and tension levels to be programmed.
