Abstract

UN CONMITADOR DE TELECOMUNICACIONES ATM CONTINE UNA PLURALIDAD DE PLANOS DE CONMUTACION PARALELA DE DATOS Y UN PLANO CENTRAL PARALELO, TENIENDO CADA PLANO UN NUMERO IGUAL DE PUERTOS DE ENTRADA Y PUERTOS DE SALIDA Y UNA UNIDAD CENTRAL DE CONMUTACION PARA CONECTAR CADA PUERTO DE ENTRADA CON CUALQUIER PUERTO DE SALIDA. EL CONMUTADOR TAMBIEN INCLUYE UN DISPOSITIVO ROTATIVO PARA CONECTAR CADA PUERTO DE ENTRADA CICLICAMENTE CON CADA RANURA TEMPORAL DE LA UNIDAD CONMUTADORA CENTRAL, Y UN SEGUNDO DISPOSITIVO ROTATIVO PARA CONECTAR CADA RANURA TEMPORAL DE LA UNIDAD CONMUTADORA CENTRAL CICLICAMENTE A CADA PUERTO DE SALIDA.
