| Sistemas de transmisión de quinta generación para servicios de televisión por cable interactivos – Módems de cable IP |
La Recomendación UIT-T J.224 especifica la quinta generación de sistemas de transmisión de datos de alta velocidad por cable. Los sistemas de transmisión de la quinta generación introducen varias características nuevas que se basan en las anteriores Recomendaciones UIT-T, entre ellas, UIT-T J.112 y UIT-T J.122 y series de Recomendaciones UIT-T J.222.x y UIT-T J.223.x. La Recomendación UIT-T J.224 incluye nuevas características fundamentales para la capa física (PHY) y establece un modo de funcionamiento de la especificación de interfaz de servicio de datos por cable (DOCSIS) totalmente dúplex, e incluye mejoras en los protocolos de la capa de control de acceso al medio (MAC), así como requisitos para los de la capa superior, por ejemplo, el protocolo de Internet (IP) y el protocolo de configuración dinámica de anfitrión (DHCP). Las especificaciones de la quinta generación de módems por cable incorporan todas las de la cuarta generación.
NOTA – La estructura y el contenido de la Recomendación UIT-T J.224 se han organizado para facilitar su uso mediante referencias directas al material fuente original, basándose en el reconocimiento de CableLabs por la UIT de conformidad con la Recomendación UIT-T A.5. |
