Abstract

Un sistema de intercomunicación para efectuar varias telecomunicaciones simultáneas separadas no interferentes entre pares de línea, conectadas a un medio de transmisión común que porta las telecomunicaciones, comprendiendo en combinación un centro de control de conmutación común a todas la líneas, medios en dicho centro para generar una serie de canales eléctricos cada uno de la clase que tiene un impulso regularmente recurrente cuyo sincronismo identifica el canal, medios también en dicho centro para asociar uno cualquiera libre de dichos canales con un par de dichas líneas entre las cuales se ha de efectuar la comunicación, estando dichas líneas conectadas a dicho centro por grupos de conductores multiplicados con lo que cada línea es identificada por un juego de impulsos codificados simultáneos sobre conductores multiplicados respectivos en dichos grupos.
