Abstract

LA INVENCION SE REFIERE A UN SISTEMA DE RADIOTRASMISION EN EL QUE, 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 Y SE ALCANZA EN EL CANAL DE RADIO LA NECESARIA RESISTENCIA A LAS PERTURBACIONES. PARA ESTO, LOS MODEM INSTALADOS EN LA ESTACION CENTRAL Y EN LA ESTACION DEL ABONADO LLEVAN L CANALES EMISORES Y K CANALES RECEPTORES (ENC1 A ENCL, IF1 A IFL, MOD1 A MODL, DEM1 A DEMK, DF1 A DFK, DEC1 A DECK), DE LOS QUE COMO MAXIMO L-1 ESTAN ACTIVADOS EN DIRECCION DE EMISION Y COMO MAXIMO K-1 EN DIRECCION DE RECEPCION. SI SE MODIFICAN LOS CANALES DE TRASMISION EN RELACION CON EL NUMERO DE SOPORTES Y/O DE PARAMETROS DE TRASMISION DE LOS SOPORTES INDIVIDUALES, POR LO MENOS EL CANAL DE EMISION/RECEPCION NO ACTIVADO SE AJUSTA PARA LOS NUEVOS PARAMETROS DE TRASMISION Y, DESPUES DE FINALIZAR LA ADQUISICION DE LOS NUEVOS PARAMETROS, SE CONMUTA A LOS NUEVOS CANALES DE EMISION Y RECEPCION.
