Abstract

EL ACOPLAMIENTO DE UNA LINEA DE CONEXION DEL ABONADO SE REALIZA DE FORMA CAPACITIVA (C, K). EN EL INTERRUPTOR DEL PUESTO DE CORTE DE LA LINEA DEL ABONADO (SLIC) DEL INTERRUPTOR DE CONEXION, ESTA FORMADO UN CAMINO DE ACOPLAMIENTO CORRESPONDIENTE AL ELEMENTO DE FILTRO F QUE VA DE LA SALIDA DE EMISION DE CUATRO CABLES HACIA LA ENTRADA DE RECEPCION DE LOS CUATRO CABLES, MEDIANTE EL CUAL SE ACCIONA UN AJUSTE BASE DE LA IMPEDANCIA DE DOS CABLES, QUE ES MAYOR QUE LA IMPEDANCIA DEL PUENTE DE ALIMENTACION. ESTE AJUSTE BASE SE REFUERZA PARA ALCANZAR UN VALOR EXACTO CON LA AYUDA DE UN FILTRO PROGRAMABLE Z, B QUE SE UNE CON EL RAMO DE RECEPCION DE CUATRO CABLES AL RAMO DE EMISION DE CUATRO CABLES EN UNA PIEDRA DE CONSTRUCCION (SICOFI) JUNTO CON EL INTERRUPTOR DE INTERRUPCION DE CORTE (SLIC1) Y ADEMAS GARANTIZA QUE LA SEGUNDA IMPEDANCIA DEL CABLE TENGA UN VALOR COMPLEJO.
