Abstract

Un equipo dual identificador de llamadas telefónicas mejorado, que permite observar, antes de contestar, el número que llama, que contiene un luminoso y que además despliega mensajes en español o inglés y es modificable por el usuario, útil para formatos de identificador (ID) de usuario que llama a una central de telefonía FSK (modulación por variación de frecuencia) como DTMF (doble tono multifrecuencia), para recibir y decodificador señales transmitidas a líneas de abonados de teléfono, dichas líneas tienen cada una, una primera línea y una segunda línea caracterizado en que comprende: una MCU (unidad de microcontrolador) diseñada para procesar datos y proporcionar señales de salida, incluye memoria no volátil para almacenar datos y programas con un mayor número de funciones, dicha unidad MCU tiene un selector de formato para determinar si está por enviar señales de formato de (ID) de usuario que llama de formato FSK ó DTMF; dicha unidad MCU está conectada a un primer y segundo oscilador, un demodulador de FSK para demodular las señales de identificador (ID) del llamante en formato FSK transmitidas por la primera línea y la segunda línea, dicho selector de formato conecta el demodulador de FSK y proporciona una señal de activación de FSK, el selector de formato determina el formato de ID del llamante por FSK y proporciona la señal de activación FSK que incluye un detector de corriente de inicio de llamada y un medidor de duración y si ambas se encuentran dentro de valores predeterminados escoge el formato de ID de llamante por FSK y proporciona dicha señal de activación de FSK al demodulador de FSK, dicho demodulador está conectado a un tercer oscilador el microncontrolador se encuentra conectado al demodulador de FSK por una primera línea de activación de FSK en la cual se transmite la señal de activación de FSK; ...<EMI FILE="99079897_1" ID="1" IMF=JPEG > SOLICITUDES DE PATENTES DE INVENCIÓNORDENADAS PUBLICAR EN OCTUBRE DE 2002 An improved dual telephone caller ID device, which allows you to observe, before answering, the calling number, which contains a light and which also displays messages in Spanish or English and is user modifiable, useful for identifier (ID) formats of user calling an FSK telephone exchange (frequency variation modulation) such as DTMF (multifrequency double tone), to receive and decoder signals transmitted to telephone subscriber lines, said lines each have a first and a second line characterized in that it comprises: an MCU (microcontroller unit) designed to process data and provide output signals, includes non-volatile memory to store data and programs with a greater number of functions, said MCU unit has a format selector to determine if it is about to send signals from the user (ID) format that it calls from FSK or DTMF format; said MCU unit is connected to a first and second oscillator, an FSK demodulator to demodulate the caller's identifier (ID) signals in FSK format transmitted by the first line and the second line, said format selector connects the FSK demodulator and provides an FSK activation signal, the format selector determines the caller's ID format by FSK and provides the FSK activation signal that includes a call start current detector and a duration meter and if both are within default values choose the caller ID format by FSK and provide said FSK activation signal to the FSK demodulator, said demodulator is connected to a third oscillator the microncontroller is connected to the FSK demodulator by a first FSK activation line in which transmits the FSK activation signal; ... <EMI FILE = "99079897_1" ID = "1" MFI = JPEG> INVENTION PATENT APPLICATIONS ORDERED PUBLISHED IN OCTOBER 2002
