| Concepción, estructura e instalación de redes metálicas de acceso de banda ancha, incluidas las redes metálicas conectadas a las redes de fibras ópticas |
En la Recomendación UIT-T L.71 se trata el diseño, la construcción y la instalación de cables de red para el acceso en banda ancha. Para diseñar la red de cables metálicos para el acceso en banda ancha, en primer lugar es necesario estudiar el número de líneas que se han de facilitar, el tipo de sistema de acceso, como xDSL, que se va a instalar y la disponibilidad de redes de cobre existentes. Esta Recomendación contiene además un proceso de diseño y ejemplos de construcción. |
