Abstract

Un método para mitigar los efectos del ruido de diafonía en una red de comunicación de línea de abonado digital, DSL, de alto ancho de banda, que comprende: proporcionar un par de transceptores que funcionen en la red de comunicación DSL; la detección de una presencia de un nivel de ruido notablemente incrementado que afecte a un miembro receptor (201) del par de transceptores, durante la operación normal, estando el método caracterizado por comprender, además: la generación y reenvío de un mensaje corto, desde el miembro receptor (201) a un miembro transmisor (202) del par de transceptores indicando a un conmutador una referencia de transmisión ajustada, en donde el mensaje corto incluye una pluralidad de valores de reducción de bits, br, para ajustar una referencia de transmisión a la referencia de transmisión ajustada; la recepción, por el miembro receptor (201) de una señal de iniciación operativa procedente del mismo transmisor (202) para iniciar la conmutación a la referencia de transmisión ajustada y la sincronización de un desplazamiento operativo con el miembro transmisor (202) por el miembro receptor (201) para la utilización por la comunicación de la referencia de transmisión ajustada.
