Abstract

Método y aparato para transferir dos senales de datos analógicas a través de una sola línea de par trenzado entre sitios primero y segundo. En el primersitio, las dos senales de datos analógicos de 4-conductores son convertidas en una senalbinari a multiplexada, la senal binaria multiplexada es convertida enuna senal codificada digital de 2-conductores; la senal codificada digital de 2-conductores es transferida a través de un solo par trenzado a un segundositio; y en el segundositio, la s enal digital de 2-conductores es convertida en una senal binaria multiplexada, y la senal binaria multiplexada esconvertida en dos senales de datos analógicas. El aparato incluye un terminal de oficina central de datosanalógicos de 4-co nductores 100 y unterminal remoto de datos analógicos de 4-conductores dual 110. El aparato puede proveer una ganancia de 4:1 mediante la multiplexación de las senalesque representan las senales de datos analógicas de cuatroconductores.
