Abstract
Un circuito de línea de abonado, utilizado en una central telefónica automática, en donde se aplica la corriente continua desde la central a través de los arrollamiento de un transformador, conectado cada uno entre un terminal del generador de corriente continua y uno de los hilos de la línea, en donde el transformador tiene un arrollamiento adicional a través del cual se puede aplicar una corriente alterna, tal como la corriente de llamada, a los hilo de la línea, en donde se utiliza un dispositivo de efecto Hall para detectar el paso de una corriente continua por los hilos de la línea, por ejemplo, debido al cierre de la misma y en donde el circuito magnético necesario para el dispositivo de efecto Hall contiene también los arrollamientos del transformador mencionados anteriormente.
