Abstract

LA INVENCION PERMITE TRANSMITIR PARES DE FRECUENCIAS VOCALES ENTRE N FRECUENCIAS PREDETERMINADAS SOBRE UNA RED TELEFONICA DE TRANSMISION DE PALABRA EN FORMA DE UN MULTIPLEX DE TRAMOS BINARIOS DE PALABRA QUE TIENE UN FORMATO DETERMINADO. PARA ESTO SE A ASIGNADO A CADA FRECUENCIA VOCAL O A CADA PAR DE FRECUENCIAS UN CODIGO NUMERICO; SE GENERAN LOS CODIGOS NUMERICOS RESPECTIVOS EN RESPUESTA A UN CONTROL DE EMISION DE UN PAR DE FRECUENCIAS; SE INSERTA CADA CODIGO NUMERICO EN UN TRAMO NUMERICO EN DICHO FORMATO QUE COMPRENDE UNA PALABRA DE IDENTIFICACION QUE CONSTITUYE UN GRUPO EXCLUIDO PARA LOS TRAMOS DE PALABRA; Y, A LA RECEPCION, SE GENERAN LOS PARES DE FRECUENCIAS VOCALES RESPECTIVOS MEDIANTE EL DECODIFICADOR DE PALABRA, EN RESPUESTA AL RECONOCIMIENTO DE DICHOS CODIGOS NUMERICOS, EN SINCRONISMO CON LOS TRAMOS QUE COMPRENDEN UNA DE DICHAS PALABRAS DE IDENTIFICACION.
