Abstract

Un método para ajustar un error de fase incluye un primer dispositivo que detecta un error de fase en una interfaz de sincronización del primer dispositivo. El primer dispositivo que modifica un parámetro de protocolo de sincronización DOCSIS en función del error de fase detectado. El primer dispositivo que provoca una modificación de la salida de sello de tiempo de un segundo dispositivo de una manera basada en el error de fase detectado mediante la modificación del parámetro del protocolo de sincronización DOCSIS.
