Abstract

Un método y aparato (200) para convertir una señal de canal de voz análoga una señal digital de 4 alambres en una sola señal de 2 alambres que se puede transferir sobre una sola línea en par tranzada (205). En aspecto, el método comprende los pasos de convertir la señal de canal de voz análoga en una primera señal binaria, convirtiendo la señal digital de 4 alambres en una segunda señal binaria, combinando la primera señal binaria y la segunda señal en una señal binaria de velocidad superior y convirtiendo la señal binaria de velocidad superior en una señal digital de 2 alambres que se puede transmitir a otra ubicacion sobre una sola linea en par tranzada. En otro aspecto, el método comprende los pasos de convertir una señal digital de 2 alambres a una señal binaria da velocidad superior, separando una primera señal binaria de una señal binaria de velocidad superior y convirtiendo la primera señal binaria en una señal de canal de voz análoga y convirtiendo una segunda señal binaria en una señal digital de 4 alambres. El aparato (200) incluye una terminal remota de datos digital positiva de voz (203) instalada fácilmente y terminal de oficina central de datos digital positiva de voz (201). El aparato puede proveer una ganancia de 3 a 1 pares multiplexando señales que representan las señales de teléfono de voz análogas y señales de datos digitales de 4 alambres.
