Abstract

PROCEDIMIENTO Y DISPOSICION PARA LA TRANSMISION SEGURA DESDE EL PUNTO DE VISTA DE LA TECNICA DE SEÑALES DE DATOS SERIADOS ENTRE ORDENADORES SEGUROS QUE TRABAJAN PREFERENTEMENTE CON DOS CANALES CON UTILIZACION DE UN SISTEMA DE CANAL COMUN DE DOBLE ANILLO. EN REGIMEN DE SERVICIO NORMAL, LOS DOS CANALES COMUNES ANULARES SON CIRCULADOS EN PARALELO REDUNDANTES EN SENTIDO OPUESTO POR LOS DATOS, ENCONTRANDOSE ASIGNADO A CADA CANL DE CADA ORDENADOR UN CANAL COMUN ANULAR, POR MEDIO DE ACOPLADORES DEL CANAL COMUN ACTIVOS. EN CASO DE AVERIA LOS CANALES COMUNES ANULARES SON INTERRUMPIDOS CICLICAMENTE POR TRAMOS PARA LA LOCALIZACION DEL PUNTO DE FALLO Y SE CREAN CONEXIONES TRANSVERSALES CON EL OTRO CANAL COMUN ANULAR CORRESPONDIENTE. TRAS LA LOCALIZACION DE LA AVERIA LOS TRAMOS CONTIGUOS CON SEPARACION DEL TRAMO AFECTADO DE AVERIA SON PASADOS DE FORMA CONTINUA A UNA ESTRUCTURA ANULAR SIMPLE SIN REDUNDANCIA.
