| Spécifications de l'interface du service de transmission de données par câble: interface radioélectrique |
 |
La présente annexe établit les spécifications de l'interface radioélectrique des systèmes de transmission de données par câble à haute vitesse.Deux options sont présentées pour la technologie de la couche Physique. L'une est basée sur la distribution télévisuelle multiprogramme vers l'aval telle qu'elle est déployée en Amérique du Nord avec des canaux à 6 MHz, et qui prend en charge la transmission vers l'amont dans la région entre 5 MHz et 42 MHz. L'autre est basée sur le système européen correspondant de distribution télévisuelle multiprogramme et prend en charge les flux vers l'amont dans la région entre 5 MHz et 65 MHz. |
