Abstract

L'invention concerne un système et un procédé permettant la transmission des signaux radioélectriques sur trajet multimédia. On décrit un système hertzien à porteuse multimédia capable de recevoir une série de signaux d'entrée normalisés, du type DSO/EO, T1/E1, T2/E2 et/ou T3/E3, aux fins de transmission sur canal radioélectrique. Le système considéré utilise de manière sélective le mode d'accès multiple par répartition dans le temps (AMRT) et/ou d'accès multiple par code de répartition (AMCR). Ledit système transmet les différents signaux d'entrée via porteuse radioélectrique, il reçoit les signaux transmis et convertit ces signaux en base (norme) de signalisation recherchée, pour acheminement vers des destinations spécifiques.
