Abstract

Dispositivo electrónico de marcación automática de un número arbitrario de dígitos conectable a cualquier aparado de teléfono, que consta de un circuito de detección y marcación mediante tonos multifrecuencia (DTMF) conectado mediante un filtro adaptador a la línea telefónica (FL) y un conmutador (CC) de estado sólido, conectados todos ellos a un microcontrolador (MC). El circuito de detección y marcación (DTMF) es alimentado mediante un puente de diodos (PD), el cual actúa de interruptor electrónico abriendo la línea al retirar la corriente de carga de los terminales positivo y negativo del puente de diodos (PD). La corriente de carga es producida por un circuito basado en un transistor montado como conmutador y gobernado por el microcontrolador (MC) alimentado por un condensador, incluyendo el microcontrolador (MC) una memoria de lectura programable y borrable eléctricamente (EEPROM) destinada a almacenar los datos de marcación. El dispositivo electrónico de marcación automática puede conectarse exterior o interiormente al sistema de telefonía, pudiendo ser activado o desactivado de forma voluntaria. Figura 1.Electronic device for automatic dialing of an arbitrary number of digits that can be connected to any telephone device, consisting of a detection and dialing circuit by means of multi-frequency tones (DTMF) connected by means of an adapter filter to the telephone line (FL) and a switch (CC ) solid state, all connected to a microcontroller (MC). The detection and marking circuit (DTMF) is powered by a diode bridge (PD), which acts as an electronic switch opening the line by withdrawing the load current from the positive and negative terminals of the diode bridge (PD). The load current is produced by a transistor-based circuit mounted as a switch and governed by the microcontroller (MC) powered by a capacitor, the microcontroller (MC) including an electrically erasable programmable read memory (EEPROM) intended to store the dialing data. The electronic automatic dialing device can be connected externally or internally to the telephone system, and can be activated or deactivated voluntarily. Figure 1.
