Abstract

La presente invención se refiere a un aparato principal de datos, que emplea un ducto de transmisión de datos, que incluye tres líneas de comunicaciones para transmitir un primer mensaje de datos desde el aparato principal de datos, a un segundo aparato de datos, a una primer velocidad de transferencia de datos y para transmitir un segundo mensaje de datos del aparato principal de datos al segundo aparato de datos, a una segunda velocidad de transferencia de datos, cada uno de los dos mensajes de datos tienen una pluralidad de bits binarios, cada bit tiene un estado binario cero o un estado binario uno, por un período de tiempo, el cual está relacionado a la velocidad de transferencia de datos, el aparato principal de datos se caracteriza porque comprende: medios para aplicar un primer estado binario a una primer y segunda de tres líneas de comunicaciones, antes y después del primer mensaje de datos, medios para acoplar el primer mensaje de datos a la primera y segunda de las tres líneas de comunicaciones; medios para aplicar un segundo estado binario a la primera de las tres líneas de comunicaciones, cuando el primer mensaje de datos no se transmite; y medios para aplicar los bits binarios del segundo mensaje de datos a la tercera de las tres líneas de comunicaciones, mientras que el segundo estado binario se aplica a la primera de las tres líneas de comunicaciones.
