Abstract

Disposición de circuitos para centrales de telecomunicación, especialmente centrales telefónicas, que conectan digitalmente de modo multiplexado en el tiempo, con un campo acoplador especial para el acoplamiento de señales de escucha con órganos de conexión, que junto con el campo acoplador de comunicaciones previsto para el intercambio de informaciones de conversación y de datos produce la comunicación entre órganos de conexión y emisores de señales de escucha y las elabora digitalmente, caracterizada porque el campo acoplador especial para el acoplamiento de señales de escucha, además de un carril colector de recepción previsto para ello, contiene también un carril colector de emisión con el que están conmutados los receptores de selección y los receptores de tono, con los cuales son comunicados en caso necesario los órganos de conexión.
