Le DCS est le nom commercial en Belgique du réseau de transmission de données par paquets utilisant le protocole X.25 (en France, son homologue porte le nom de Transpac). Initialement développé par l'ex-RTT (régie des Téléphones et Télégraphes) en 1980, ce service continue d'être commercialisé par Belgacom en 2009 et ce pour quelque temps encore. Bien que vétuste et lente, cette technologie se caractérise par son extrême fiabilité ce qui la rend encore très utile pour les transmissions ne nécessitant pas de grandes performances de vitesse (terminaux de payement, loterie nationale, ligne louées inter-bancaires, balises d'alerte nucléaires, etc...) tant au niveau national qu'international (le X25 est un protocole mondialement utilisé). Son exploitation devrait toutefois s'arrêter à l'horizon 2011 pour le trafic international.
