| Especificaciones de interfaces de servicios de datos por cable: Especificación de la interfaz de radiofrecuencia |
 |
Este anexo define las especificaciones de interfaces de radiofrecuencia para sistemas de datos por cable de alta velocidad.Se incluyen dos opciones en la tecnología de la capa física. Una opción se basa en la distribución en sentido descendente de la televisión multiprogramas empleada en Norteamérica, que utiliza una disposición de canales de 6 MHz y soporta transmisiones en sentido ascendente en la región entre 5 MHz y 42 MHz. La otra opción se basa en la distribución de televisión multiprogramas europea que, soporta transmisiones en sentido ascendente en la región entre 5 MHz y 65 MHz. |
