Abstract
METODO DE CONTROL PARA UN SISTEMA DE TELECOMUNICACIONES DISTRIBUIDO. LAS ESTACIONES (1 A 96) Y SUS ENLACES (1 A 24) SE REUNEN EN GRUPOS CON UN CONTROLADOR DE GRUPO AL QUE ESTAN CONECTADAS, ESTANDO A SU VEZ UNIDOS TODOS LOS GRUPOS ENTRE SI Y CON UNA UNIDAD DE PROCESAMIENTO CENTRAL POR UN BUS DE SISTEMA. CADA CONTROLADOR DE GRUPO LLEVA UNA MEMORIA RAM, DONDE SE ALMACENAN, EN FORMA DIGITAL, DATOS QUE SE DEBEN SUMINISTRAR A UNA ESTACION CUANDO ESTA OCUPADO EL BUS DE DICHA ESTACION. EL CONTROLADOR DE GRUPO INTERROGA REGULARMENTE A LA MEMORIA RAM Y SI EL BUS DE DESTINO ESTA LIBRE SE SUMINISTRA LA INFORMACION ALMACENADA. A
