Abstract
EN UN SISTEMA DE RADIOTRASMISION PUNTO A MULTIPUNTO, PARA PERMITIR LA ASIGNACION FLEXIBLE DE CAPACIDADES DE TRASMISION SIN CORTAR O PERTURBAR LAS RADIOCOMUNICACIONES ESTABLECIDAS, SE HA PREVISTO UN DISPOSITIVO DE MANDO (SE) QUE, SI CAMBIAN LOS CANALES DE TRASMISION EN LA ESTACION CENTRAL Y LA ESTACION DEL ABONADO, AJUSTA UNO O MAS PARAMETROS DE TRASMISION DE FORMA QUE EL ANCHO DE BANDA DEL CANAL DE RADIO DISPONIBLE SE EXPLOTA OPTIMAMENTE. PARA ESTO, LOS MODEM INSTALADOS EN LA ESTACION CENTRAL Y EN LA ESTACION DEL ABONADO LLEVAN DOS RUTAS DE SEÑALES EMISORAS Y DOS RUTAS DE SEÑALES RECEPTORAS (ENC1, ENC2, IF1, IF2, MOD1, MOD2, DEM1, DEM2, DF1, DF2, DEC1, DEC2), DE LOS QUE SOLAMENTE UNO ESTA ACTIVADO PARA LA TRASMISION DE SEÑALES. LAS SALIDAS DE LAS RUTAS DE SEÑALES DE EMISION Y LAS ENTRADAS DE LAS RUTAS DE SEÑALES DE RECEPCION ESTAN CONECTADAS A DIPLEXORES (FWS, FWE). SI SE MODIFICAN LOS CANALES DE TRASMISION, LA RUTA DE SEÑALES INACTIVA EN ESE INSTANTE SE AJUSTA PARA LOS NUEVOS PARAMETROS DETRASMISION Y, DESPUES DE FINALIZAR LA ADQUISICION DE LOS NUEVOS PARAMETROS, SE CONMUTA A LA NUEVA RUTA DE SEÑALES.
