Abstract

EN SISTEMAS DE CONEXION DE GRUPOS DE REDES DE DIRECCION CENTRAL, LAS CENTRALES SOLO SON INFORMADAS MEDIANTE DISTRIBUIDORES DE SEÑALES DIGITALES SOBRE UNA RECEPCION DE SEÑALES AIS, O MEDIANTE AUSENCIAS EN LA SEÑAL DIGITAL, PERO NO MEDIANTE OTROS EQUIPOS DE EXTENSIBILIDAD. POR TANTO, LOS DISTRIBUIDORES DIGITALES DE SEÑALES NO PUEDEN RECONOCER, DONDE SE ALIMENTA UNA SEÑAL AIS, Y DAN LAS MISMAS SEÑALES EN DISTINTAS CIRCUNSTANCIAS, SIN QUE LAS CENTRALES PUEDAN RECONOCER SI HAY UNO O MAS PUNTOS DEFECTUOSOS. EL INVENTO PROPONE LA INTRODUCCION DE UNA SEÑAL AIS MODIFICADA, QUE CONSISTE EN UNA SEÑAL AIS NORMAL, SEÑAL DE DURACION UNO, Y UN RECONOCIMIENTO. ESTOS SON EQUIDISTANTES DE CERO, CON UNA FRECUENCIA MENOR QUE 10-3, O FORMAN UNA SEÑAL ADICIONAL. CUANDO UN DISTRIBUIDOR DE SEÑALES DIGITALES (8) RECIBE UNA SEÑAL AIS NORMALIZADA O RECONOCE OTRAS AUSENCIAS, ALIMENTA UNA SEÑAL AIS MODIFICADA EN LA EXTENSION DE SALIDA (15). LOS DISTRIBUIDORES DE SEÑALES DIGITALES SIGUIENTES (9, 10, 11, 12) SOLO ALIMENTAN DE NUEVO UNA SEÑAL AIS CUANDO RECONOCEN LA MODIFICACION, Y NO TOMAN LA INFORMACION DE UNA CENTRAL REGIONAL (3, 4). LA CENTRAL DE DIRECCION DE REDES (1) CONECTA UN RECORRIDO SUSTITUTIVO (16) DEBIDO A LA INFORMACION DEL DISTRIBUIDOR DIGITAL (8). ESTE DISPOSITIVO ES PARA EL USO EN SISTEMAS DE CONEXION DE REDES CON UNA DIRECCION CENTRAL.
