Abstract

En un sistema telefónico automático; varias líneas de abonado; varias centrales telefónicas de las cuales una por lo menos es una central del tipo paso a paso que comprende selectores paso a paso; una central que llama comprendiendo selectores movidos por energía y registradores para establecer conexiones a líneas locales de abonado; estando los registradores equipados con detectores electrónicos y relés registradores para registrar el número de una llamada marcado por un abonado que llama; medios en el registrador para establecer conexiones a través de los selectores movidos por energía bajo el control del detector electrónico a líneas de abonado locales; un circuito pulsador; medios para conectar el circuito pulsador a un registrador cuando el número de la llamada registrado designa una línea llamada en una central paso a paso; medios en el circuito pulsador para accionar los selectores paso a paso; suministros de diferentes potenciales; medios en el registrador para aplicar potenciales al detector electrónico que caracterizan la selección correspondiente al número de la llamada registrado en los relés registradores; medios en el circuito pulsador para aplicar potenciales al detector electrónico que caracterizan el número de impulsos transmitido a los selectores paso a paso; y medios para detener los impulsos cuando dicho potencial aplicado a dicho detector electrónico por dicho circuito pulsador tiene una relación predeterminada con dicho potencial aplicado a dicho detector por dichos relés registradores.In an automated phone system; multiple subscriber lines; several telephone exchanges of which at least one is a switch of the step-by-step type comprising step-by-step selectors; a call center comprising power-driven selectors and registers for establishing connections to local subscriber lines; the recorders being equipped with electronic detectors and recorder relays to record the number of a call dialed by a calling party; means in the register for establishing connections through the power-driven selectors under the control of the electronic detector to local subscriber lines; a push-button circuit; means for connecting the push-button circuit to a recorder when the registered call number designates a line called at a stepper exchange; means in the push-button circuit for actuating the selectors step by step; supplies of different potentials; means in the register for applying potentials to the electronic detector that characterize the selection corresponding to the number of the call registered in the register relays; means in the push-button circuit for applying potentials to the electronic detector that characterize the number of pulses transmitted to the stepper selectors; and means for stopping the pulses when said potential applied to said electronic detector by said push-button circuit has a predetermined relationship with said potential applied to said detector by said recording relays.
