Dans cette configuration, deux ressources X.25 différentes (nous avons utilisé dspu-host pour simuler les périphériques finaux de cette configuration). Pour plus d'informations sur l'unité physique en aval (DSPU), reportez-vous aux documents suivants :
Ces deux périphériques finaux communiquent avec différentes cartes sur le site du mainframe via X.25. Les ressources X.25 distantes ont été configurées pour différentes adresses de destination (en différentes longueurs et adresses). Tout appel entrant dont l'adresse de destination X.121 correspond à la « sous-adresse dlsw qllc » du routeur est envoyé à Data Link Switching Plus (DLSw+) (avec un ID.STN IND). Lorsque DLSw+ reçoit une requête « Can You Reach » concernant une adresse MAC virtuelle dans le pool, le code QLLC (Qualified Logical Link Control) tente de configurer un circuit virtuel (VC) à l'adresse X.121 qui correspond à l'adresse MAC virtuelle spécifiée. Si un appel entrant est reçu, QLLC envoie un ID.STN.IND avec une adresse MAC virtuelle du pool à DLSw+.
Aucune spécification déterminée n'est requise pour ce document.
