Abstract

Procedimiento para el tratamiento de señales telefónicas alimentadas a través de un terminal telefónico analógico y de datos alimentados a través de un dispositivo terminal de datos en el circuito de conexión de abonados de un sistema de conmutación telefónica digital, utilizado al menos en regiones parciales para una transmisión de datos, en el que el terminal telefónico está conectado directamente y el dispositivo terminal de datos está conectado con la intercalación de un módem a través de una línea de abonados analógica común, caracterizado porque al menos los datos alimentados por el dispositivo terminal de datos (PCa, PCb) son sometidos, durante la conversión analógico/digital necesaria, a un muestreo con una frecuencia de muestreo que está por encima de la frecuencia de muestreo necesaria para informaciones telefónicas y/o los valores de muestreo, que representan datos suministrados por el dispositivo terminal de datos, experimentan una codificación según una curva característica lineal, y porque los datos tratados de esta manera y que proceden desde el dispositivo terminal de datos, son alimentados directamente a una red de transmisión de datos (DN).
