ABSTRACT:
A hybrid circuit for an electric operating and scanning interface is especially applicable to electronic recorders of electromechanical telephone stations. The hybrid circuit controls voltage and current parameters on different elements of the station in different situations. The hybrid circuit scans the condition of telephone station elements controlled by it, and programmably applies and receives current and voltage to and from the telephone station elements on which it acts.
