Abstract

Mejoras en sistemas de telecomunicación caracterizado por una central de telecomunicación en la que un equipo de identificación de abonado está asociado con un número grande de línea de abonados en una central y está dispuesto para ser puesto en uso en ciertos tipos de conexiones en respuesta a una señal de demanda procedente de un equipo en un punto intermedio en una conexión y en el que la identidad de una línea de abonado incluida en una conexión es determinada por un equipo de identificación de abonado y se usa para controlar el equipo selectivo que tiene funciones relacionadas con la conexión.Improvements in telecommunication systems characterized by a telecommunication exchange in which a subscriber identification equipment is associated with a large number of subscriber lines in an exchange and is arranged to be put into use on certain types of connections in response to a demand signal from equipment at an intermediate point in a connection and where the identity of a subscriber line included in a connection is determined by subscriber identification equipment and is used to control selective equipment having related functions with the connection.
