Abstract
Una estación remota que comprende:un dispositivo de entrada de voz para recibir señales de voz; un circuito de codificación para codificar dichas señales de voz recibidas para generar señales de voz codificadas; un generador para generar señales de información alternativas; un transmisor para transmitir en forma selectiva una de dichas señales de voz codificada y dichas señales de información alternativas; y una entrada silenciosa conmutable entre un modo silente y un modo no silente, donde dicho transmisor transmite en forma selectiva dichas señales de información alternativas cuando dicha entrada silente es colocada en dicho modo silente y transmite dichas señales de voz codificadas cuando dicha entrada silenciadora es colocada en dicho modo no silente.Una estación móvil que consta de lo siguiente: medios para recibir señales de voz; medios para codificar dichas señales de voz en marcos de voz codificados; medios para generar marcos de fondo; medios para seleccionar un modo silente; y medios para transmitir dichos marcos de fondos cuando dicho modo silente es seleccionado y para transmitir de otra forma dichos marcos de voz codificados. 1Un método para transmitir ruido de fondo durante el silenciamiento selectivo de un dispositivo de radio comunicación que consta de los siguientes pasos: recibir señales de voz de entrada; codificar dichas señales de voz de entrada para generar marcos de voz codificados; determinar si se ha activado una función de silenciamiento; transmitir dichos marcos de voz codificados si dicha función de silenciamiento no se ha activado; y transmitir marcos de información diferentes de dichos marcos de voz codificados si se ha activado dicha función de silenciamiento.
