Abstract

Circuito perfeccionado de emisión de señal acústica para uso en su aparato telefónico del tipo en que las señales de conversación y de llamada son transmitidas a través de líneas separadas a fin de permitir llamadas también a un abonado en el estado descolgado, caracterizado por un circuito regulador de nivel incluido en la línea de señales de llamada que está dispuesto para ser controlado por un contacto en un conmutador de transmisión de conversación (conmutador de gancho) de modo que la señal acústica se atenúa cuando está conectada la línea de transmisión de conversación.
