Abstract

UN CIRCUITO Y METODO QUE ELIMINA LAS PUNTAS DE VOLTAJE GENERADAS POR RETROCESO INDUCTIVO, Y GENERA UNA SEÑAL QUE ES ACTIVA MIENTRAS UN REPETIDOR ESTA SIENDO DESCONECTADO Y DURANTE UN PERIODO DADO DESPUES DE ELLO. ESTA SEÑAL PUEDE SER USADA PARA POTENCIAR LOS CIRCUITOS QUE SUMINISTRAN LAS SEÑALES A LOS CONTACTOS DEL REPETIDOR, POR ESO PERMITIR AL REPETIDOR DESCONECTARSE SIN CORRIENTE O POTENCIAL DE VOLTAJE EN SU CONTACTO, POR EJEMPLO CONMUTACION SECA. LA SEÑAL GENERADA DEBE TAMBIEN SER USADA PARA INCAPACITAR EL DETECTOR DE CONMUTACION DEL ENGANCHE DEL TELEFONO O POTENCIAR EL CIRCUITO DE ALIMENTACION DE BATERIA QUE ALIMENTA LA LINEA DEL SUSCRIPTOR. LA ENERGIA DE LA BOBINA DEL REPETIDOR GENERA UNA SEÑAL QUE ES ACTIVA MIENTRAS EL REPETIDOR ESTA SIENDO DESCONECTADO. ESTE INVENTO USA UN MINIMO NUMERO DE COMPONENTES Y EL CIRCUITO ES AJUSTABLE COMO LARGO LA SEÑAL GENERADA PERMANECE ACTIVO DESPUES DE QUE EL REPETIDOR ES DESCONECTADO.
