Abstract
POR RAZONES DE SEGURIDAD SE HAN DUPLICADO LOS GRUPOS DE CONEXIONES. DEBIDO A ESTO, LA TRANSCONEXION DE LAS LINEAS DE ENTRADA AL CAMPO DE ACOPLAMIENTO PUEDE REALIZARSE A TRAVES DE DISTINTOS TRAYECTOS DE SEÑALES. PARA EVITAR POSIBLES PERTURBACIONES DURANTE LAS CONMUTACIONES, LOS CORRESPONDIENTES PUNTOS DE INTERSECCION ESTAN DOTADOS DE MEMORIAS DE COMPENSACION. LOS DATOS CONTENIDOS EN ESTAS MEMORIAS SON GRABADOS O LEIDOS, SINCRONIZADOS DE FASE Y DE CUADRO, CON UNA INDEXACION UNIFORME. ESTA INDEXACION UNIFORME SE OBTIENE A PARTIR DE LA INDEXACION BASE EWSD. DEBIDO A LAS DISTORSIONES DE RETARDO Y LAS TOLERANCIAS DE COMPONENTES, ESTA INDEXACION BASE HA DE REGENERARSE A TRAVES DEL ESQUEMA DE CONEXIONES DE LA PRESENTE INVENCION ANTES DE TENER CONTACTO CON LA MEMORIA DE COMPENSACION.
