Abstract
SE PRESENTA UN METODO PARA MONITORIZAR UN CANAL DE COMUNICACIONES DE UNA RED PARA DETECTAR SEÑALES ESPECIFICAS DE ACTIVACION DTMF TRANSMITIDAS POR UN USUARIO DE LA RED DURANTE EL PERIODO PRE-RESPUESTA COMO DURANTE UN PERIODO POST-RESPUESTA DE UNA LLAMADA SOPORTADA POR EL CANAL, Y, EN RESPUESTA A LA SEÑAL DE ACTIVACION DTMF DETECTADA, SE PROHIBE DE FORMA CONTROLABLE LA PROPAGACION SUBSECUENTE DE LAS SEÑALES DTMF TRANSMITIDAS SOBRE EL CANAL POR EL USUARIO DE LA RED. ESPECIFICAMENTE, SE ELIMINA LA POSIBLE DISRUPCION DE UNA COMUNICACION ENTRE EL USUARIO DE LA RED Y OTROS USUARIOS PROVOCADA POR LA TRANSMISION DE SEÑALES DTMF TRANSMITIENDO DE FORMA VENTAJOSA LAS SEÑALES DE ACTIVACION DTMF DURANTE EL PERIODO PRE-RESPUESTA DE UNA LLAMADA. ADEMAS, SE SOSLAYAN OTRAS DEFICIENCIAS DE ANTERIORES DISPOSITIVOS DE RED PARA RESTRINGIR LA PROPAGACION DE LAS SEÑALES DTMF, YA QUE LA INVENCION PUEDE LLEVARSE A CABO SIN LA INTRODUCCION DE NINGUN RETARDO DE PROPAGACION SIGNIFICATIVO EN LA RED.
