Abstract

La presente invencion se refiere a una red de comunicaciones y método que se proporcionan para comunicar entre una central/extremo delantero y una pluralidad de unidades de extremo (EUs). Un primer medio de transmision de conecta entre la central y un nodo intermedio. Una pluralidad de segundos medios de transmision se conecta entre la central y una pluralidad de nodos de minifibras. El nodo intermedio también se asocia con cada uno de los nodos de minifibra, de manera tal que un servicio de difusion análogo puede enviarse sobre el primer medio de transmision a cada uno de los nodos de minifibras. Además, servicios digitales conmutados y servicios de difusion digital también se envían sobre los segundos medios de transmision a cada unos de los nodos de minifibras. Los nodos de minifibras combinan las señales y envían las señales combinadas a un sub-conjunto correspondiente de EUs.
