Abstract

L'invention concerne un répartiteur automatisé servant à raccorder une pluralité de lignes d'abonné à une pluralité de lignes de matériel de bureau, le répartiteur automatisé comportant un dispositif de débordement et une pluralité de réseaux de commutateurs, chaque réseau de commutateurs comportant une pluralité correspondante d'entrées et une pluralité correspondante de sorties, dans lequel une première partie de la pluralité correspondante d'entrées est connectée au dispositif de débordement et une deuxième partie de la pluralité correspondante d'entrées du réseau de commutateurs est connectée à au moins une ligne d'abonné correspondante de la pluralité de lignes d'abonné et dans lequel une première partie de la pluralité correspondante de sorties du réseau de commutateurs est connectée au dispositif de débordement, tandis qu'une deuxième partie de la pluralité correspondante de sorties du réseau de commutateurs est connectée à au moins une ligne de matériel de bureau sélectionnée de la pluralité de lignes de matériel de bureau. Le dispositif de débordement est utilisé pour réacheminer le trafic en provenance d'un réseau de commutateurs donné à au moins un autre réseau de commutateurs si un nombre de services requis par les clients de la pluralité de lignes d'abonné dépasse un nombre de services de la pluralité de lignes de matériel de bureau disponibles au niveau du réseau de commutateurs donné.
