Abstract
DONDE EL METODO INCLUYE: a)MEDIR LAS CARACTERISTICAS DE LA LINEA PAR TRENZADO (ATENUACION DE LINEA) EN UNA UBICACION INTERMEDIA ENTRE UNA OFICINA CENTRAL Y UN ESTABLECIMIENTO DEL USUARIO, MIDIENDO LOS NIVELES DE TONO DE ACTIVACION DSL; b)ECUALIZAR EN RESPUESTA A (a), PARA VENCER LA ATENUACION DE LINEA, SUMINISTRANDO UNA PRIMERA GANANCIA A LAS SENALES DE FLUJO DESCENDENTE DESDE LA OFICINA Y UNA SEGUNDA GANANCIA A LAS SENALES DE FLUJO ASCENDENTE DESDE EL ESTABLECIMIENTO, EN BASE A LOS NIVELES MEDIDOS; c)COMPENSAR LOS EFECTOS DEL RETARDE DE GRUPO DE LA LINEA DE PAR TRENZADO EN LA UBICACION INTERMEDIA; Y, d)FILTRAR EN ESTA UBICACION LAS SENALES DE FLUJO DESCENDENTE PARA QUE RECHACEN LAS SENALES DE FLUJO ASCENDENTE Y VICEVERSA; DONDE (b) Y (c) CORRIGEN LA DEGRADACION DE SENAL IMPUESTA POR LA LINEA DE PAR TRENZADO PARA EXTENDER LA DISTANCIA SOBRE LA CUAL LA OPERACION OCURRE EN UN NIVEL PREDETERMINADO DE RENDIMIENTO. LAS GANANCIAS SE SUMINISTRAN AMPLIFICANDO EL BAJO RUIDO DE LAS SENALES DE FLUJO PARA PROVEER UNA ALTA RELACION SENAL/RUIDO, EXTENDIENDO LA DISTANCIA SOBRE LA CUAL LA OPERACION OCURRE A UN NIVEL PREDETERMINADO DE RENDIMIENTO. LAS SENALES DE FLUJO TIENEN DIFERENTES ESPECTROS DE FRECUENCIA, Y LAS GANANCIAS SON DIFERENTES. EL ACONDICIONADOR COMPRENDE: i) PRIMER Y SEGUNDO PREAMPLIFICADOR DE GANANCIA PARA ECUALIZAR RESPECTIVAMENTE EL PAR TRENZADO PARA LAS SENALES DE FLUJO DESCENDENTE; ii)PRIMER Y SEGUNDO DETECTORES PARA LOS NIVELES DE TONO; Y, iii)MICROPROCESADOR PARA (ii)
