Abstract
DISPOSITIVO PARA SUMINISTRAR ENERGIA ELECTRICA DESDE UNA CENTRAL DE TELECOMUNICACIONES A UNA TERMINACION DE LA RED DISTANTE, QUE EMPLEA LOS HILOS CONDUCTORES DE UN BUCLE DE ABONADO DIGITAL DE DOS CONDUCTORES EN PARALELO, 7UTILIZANDO LA TOMA A TIERRA COMO TRAYECTO DE RETORNO. EN LA CENTRAL, DOS FUENTES DE ALIMENTACION PROPORCIONAN, POR SEPARADO, POTENCIA A LOS DOS HILOS DEL BUCLE PARALELO Y LA CORRIENTE SUMINISTRADA POR LAS DOS FUENTES DE ALIMENTACION SE AÑADE EN LA INTERFASE DISTANTE POR MEDIO DEL DEVANADO DE UN TRANSFORMADOR DE TOMA INTERMEDIA, QUE FORMA PARTE DEL TRANSFORMADOR UTILIZADO PARA LA TRANSMISION DE SEÑALES DE VOZ Y DE DATOS, CODIFICADAS DIGITALMENTE. UN CONVERTIDOR DC-DC, CONECTADO A LA TOMA INTERMEDIA, PROPORCIONA LA POTENCIA EXIGIDA PARA LA CIRCUITERIA DE LA INTERFASE. EL CONVERTIDOR DC-DC SE PONE A TIERRA A TRAVES DE UN FILTRO DE PASO BAJO, DISEÑADO PARA BLOQUEAR LAS SEÑALES DE RUIDO EN FRECUENCIA SUPERIOR.
