Abstract
DISPOSICION PARA INDICAR EL CIERRE DE CIRCUITO EN BUCLE EN UNA LINEA DE ABONADO DURANTE LA FASE DE LLAMADA, ESTANDO CONECTADA A UNA CENTRAL DE ENLACE DE UNA DISPOSICION DIGITAL TELEFONICA TIEMPO-MULTIPLEX A TRAVES DE UN CIRCUITO DE CONEXION DE ABONADO. ENTRE LA LINEA DE ABONADO Y LOS MEDIOS CONVERTIDORES ANALOGICOS DIGITALES DEL ELEMENTO COMPONENTE PROCESADOR DE SEÑALES ESTA INTERCALADO UN DISPOSITIVO CONMUTADOR, (MEDIANTE EL CUAL SE SUMINISTRA A DICHO ELEMENTO COMPONENTE DE PROCESADOR DE SEÑALES DURANTE LA FASE DE LLAMADA, EN LUGAR DE LA SEÑALDE TENSION PROPORCIONAL A LA CORRIENTE DE LINEA QUE FLUYE POR LA LINEA DE ABONADO); LOS FILTROS COMPRENDEN UN PASAALTOS PUESTEADO POR UN INTERRUPTOR Y SEGUIDO POR UN SUMADOR QUE SUMA LA MENOS UN PERIODO DE LA FRECUENCIA DE LA SEÑAL DE LLAMADA); Y LA SALIDA DEL SUMADOR ESTA ACOPLADA A UN COMPARADOR A SU VEZ ACOPLADO A UNA FUENTE DE TENSION DE REFERENCIA (PARA COMPARAR LA SEÑAL SUMADA CON UN VALOR DE REFERENCIA, Y AL SUPERAR LA SEÑAL SUMADA DICHO VALOR DE REFERENCIA EMITE SEÑAL INDICATIVA DEL CIRCUITO EN BUCLE).
