Abstract

UN APARATO DE FACSIMIL FUENTE (10) INCLUYE UN MODEM (38) QUE TIENE UNA VELOCIDAD DE TRANSMISION VARIABLE Y QUE ESTA CONECTADO MEDIANTE UN ENLACE DE RADIO (22) A UN APARATO FACSIMIL DE DESTINO (21) QUE ESTA UBICADO EN UNA ESTACION DE ABONADO MOVIL DENTRO DE UNA RED DE RADIO. LOS DATOS DEL FACSIMIL SON TRANSMITIDOS A UNA VELOCIDAD DE TRANSMISION DE DATOS DADA DESDE EL APARATO FACSIMIL FUENTE (10) HASTA UN MODEM (17) DENTRO DE UNA FUNCION DE TRABAJO (26) UBICADA EN LA RED DE RADIO. UNA MEMORIA DE BUFFER (41) ALMACENA LOS DATOS DEL FACSIMIL RECIBIDOS POR EL MODEM (17) DE LA FUNCION DE TRABAJO (26). LOS DATOS DEL FACSIMIL SON TRANSMITIDOS ENTONCES DESDE LA MEMORIA DE BUFFER (41) POR MEDIO DEL ENLACE DE RADIO (22) HASTA EL APARATO FACSIMIL DE DESTINO (21) DENTRO DE LA ESTACION MOVIL. SI EL ENLACE DE RADIO NO PERMITE QUE SEAN ENVIADOS LOS DATOS DEL FACSIMIL HASTA LA ESTACION MOVIL A APROXIMADAMENTE LA MISMA VELOCIDAD QUE ESTAN SIENDO RECIBIDOS POR EL MODEM (17) DE LA FUNCION DE TRABAJO (26), ESTAULTIMA SE CAMBIA PARA PONER AMBOS APARATOS EN CONFORMIDAD.
