Abstract
LA INVENCION SE REFIERE A UN SISTEMA DE TELEFONIA EN QUE HAY VARIAS TERMINACIONES DE REDES LOCALES (8) CONECTADAS A UNA CABINA URBANA (3) QUE A SU VEZ ESTA CONECTADA A UNA CENTRAL (1). LA CABINA URBANA (2) TIENE UNA FUENTE DE ENERGIA (21) PARA SUMINISTRAR ENERGIA Y UNA SEÑAL DE LLAMADA MAESTRA A CADA UNA DE LAS TERMINACIONES DE REDES LOCALES. LA FUENTE DE ENERGIA CONTIENE UN RECTIFICADOR (21) PARA RECTIFICAR LA RED DE CA (7) Y UNA SALIDA DEL RECTIFICADOR (21) ESTA CONECTADA A UNA BATERIA (22) PARA PROPORCIONAR UN RETORNO DE POTENCIA EN CASO DE UNA INTERRUPCION DEL SUMINISTRO DE ENERGIA.
