Abstract

LA INVENCION SE REFIERE A UN SISTEMA DE TRANSMISION DE RADIO ISDN LOCAL, QUE ESTA ORGANIZADO COMO UNA CELDA DE RADIO LOCAL, QUE CONSISTE EN UNA ESTACION DE RADIO ESTACIONARIA CENTRAL Y EN UNA PLURALIDAD DE CONJUNTOS DE RADIO PARTICIPANTES DESCENTRALIZADOS. EL SISTEMA DE TRANSMISION DE RADIO ESTA CONECTADO A ACCESO DE LOS ELEMENTOS DE CONEXION (CONEXIONES BASE ISDN) DE UNA OFICINA CENTRAL LOCAL, SU CENTRO O INTERCAMBIO DE RAMAL PRIVADO. EL NUMERO DE PARTICIPANTES DE RADIO ES MAYOR QUE EL NUMERO DE CANALES DE RADIO DUPLEX UTILIZADO. LA INVENCION ASEGURA A LOS PARTICIPANTES DE RADIO UNA CONEXION CON UNA INTERFASE S{SUB,0}. LA TRANSMISION DE RADIO EN EL AREA DEL PARTICIPANTE PERMITE QUE SEA DESPLAZADA LAS LIMITACIONES DE COBERTURA DE CAMPO, QUE RESULTAN POR OTRO LADO A PARTIR DE LOS PROBLEMAS DE TIEMPO DE ATENUACION Y PROPAGACION ENCONTRADOS EN EL CASO DE TRANSMISION CON HILOS. DE ACUERDO CON LA INVENCION, LA DISPOSICION DE TRANSMISION DE RADIO ESTA INSERTADA DENTRO DE UN CIRCUITO DE CONEXION DE ACCESO A SISTEMA ISDN DE DOS HILOS CON UN REPETIDOS INTERMEDIO, EN LA SECCION QUE SE EXTIENDE ENTRE EL REPETIDOR INTERMEDIO Y LA TERMINACION DE LA RED. DESPUES DE UNA RESPUESTA DE ACTIVACION, SE ASIGNA UN CANAL DE RADIO CON TIEMPO DE CADENCIA Y DE MONITORIZACION PARA ACTIVACION DE CIRCUITO DE CONEXION DE ACCESO A SISTEMA ISDN DE DOS HILOS. PARA ASEGURAR UN USO EFICIENTE DE LA ANCHURA DE BANDA DE TRANSMISION DISPONIBLE, SE DISPONE DE UN CANAL DE RADIO INDEPENDIENTE PARA CONTROL, ORGANIZACION Y MONITORIZACION. LAS INSTRUCCIONES Y LA INFORMACION REQUERIDAS SE TRANSMITEN EN CANALES DE RADIO LIBRES. LOS CONJUNTOS DE RADIO DE PARTICIPANTES RECONOCEN CANALES LIBRES GRACIAS A DISPOSICION ESPECIAL DE LAS PALABRAS DE SINCRONIZACION QUE DIFIEREN DE AQUELLAS DE LA TRANSMISION ISDN.
