Abstract

En un sistema de central de telecomunicación varias líneas designadas numéricamente un dispositivo de llamada para cada línea accionable de acuerdo con el número de las líneas llamadas un tubo de rayos catódicos que tiene electrodos en que terminan dichas líneas medios para hacer que el haz de dicho tubo barra sobre dichos electrodos varios buscadores de línea electrónicos normalmente inactivos un enlace asociado con cada buscador de línea medios que responden a la iniciación de una llamada para actuar un buscador de línea para conectar la línea que llama con el enlace asociado siempre que el haz del tubo conecte con los terminales de la línea un selector electrónico normalmente inactivo para cada línea medios que responden a impulsos accionados variablemente bajo el control del dispositivo que llama para controlar dichos selectores y medios para actuar el selector del enlace seleccionado siempre que el haz del tubo conecta con los terminales de la línea llamada.In a central telecommunications system several lines designated numerically a calling device for each line operable according to the number of the lines called a cathode ray tube having electrodes in which said lines terminate means for making the beam of said tube bar on said electrodes several normally inactive electronic line finders a link associated with each line finder means responding to the initiation of a call for actuating a line finder to connect the calling line with the associated link whenever the beam of the tube connect to the line terminals a normally inactive electronic selector for each line means responding to variably actuated pulses under the control of the calling device for controlling said selectors and means for actuating the selector of the selected link whenever the tube bundle connects with the terminals of the called line.
