Abstract
Un aparato y metodo de transmision tienen la capacidad de transmision de alta velocidad a traves de lineas telefonicas existentes utilizando tonos acusticos. Los datos pueden ser transmitidos a traves de lineas telefonicas existentes (20) convirtiendo los datos a un par, a un terceto o a otra agrupacion de tonos acusticos y transmitir la senal compuesta. Los datos, tales como un caracter ASCII (22), se convierten primero a un numero binario de 8 bits (24). Posteriormente el numero binario es utilizado para seleccionar dos tonos, un tono de alta frecuencia (28) y un tono de baja frecuencia (26). Estos tonos (26, 28) se mezclan para formar la senal compuesta (30) que se transmite (32) a traves de lineas telefonicas (20). Los tonos (26, 28) pueden ser configurados para tener diferenciacion de amplitudes o ser separados por medio de tonos de zumbido, y se mezclan para formar una senal compuesta que se transmite a traves de lineas telefonicas (20). Posteriormente la senal compuesta recibida (30) puede ser descompuesta en sus tonos constituyentes y decodificada para generar los datos transmitidos (22) en el aparato receptor.
