Abstract
EL SISTEMA CONMUTA LOS PAQUETES DE INFORMACION AFECTADOS DE PRIORIDADES SEMANTICAS Y EVENTUALMENTE DE PRIORIDADES TEMPORALES ENTRE LOS MULTIPLEX TEMPORALES ENTRANTES Y LOS MULTIPLEX TEMPORALES SALIENTES. LA DIRECCION DE MEMORIZACION (K) DE UN PAQUETE EN LA MEMORIA TAMPON (MP) DEL SISTEMA ESTA COLOCADA EN CADA FILA DE ESPERA O DOBLE FILA DE ESPERA ASOCIADA A CADA MULTIPLEX TEMPORAL SALIENTE DESTINADO A TRASMITIR EL PAQUETE. COMPRENDE UNA MEMORIA DE CAMPO DE PUNTOS (MAP) CUYAS PALABRAS (ZI) COMPRENDEN CADA UNA TANTOS BITS COMO LOS MULTIPLEX TEMPORALES SALIENTES. LAS DIRECCIONES DE LA MEMORIA (MAP) CORRESPONDEN A LAS DE LA MEMORIA TAMPON (MP). CADA BIT DE UNA PALABRA (ZI) ES UN "1" CUANDO EL PAQUETE MEMORIZADO EN LA MISMA DIRECCION QUE LA PALABRA Y DESTINADO AL MULTIPLEX TEMPORAL SALIENTE QUE CORRESPONDE AL BIT CON UNA PRIORIDAD SEMANTICA DE ALTO NIVEL Y QUE NO HA SIDO AUN TRASMITIDO POR EL MULTIPLEX SALIENTE QUE LE CONCIERNE. CADA DIRECCION DE MEMORIZACION DE EL PAQUETE ESTA ELEGIDO ENTRELAS DIRECCIONES LIBRES DE LA MEMORIA (MAP) DIRIGIENDO LAS PALABRAS (ZI) EN TODOS LOS BITS SITUADOS EN "0". CADA DIRECCION LIBRE DE LA MEMORIA (MAP) ESTA MEMORIZADA EN UNA FILA DE DIRECCIONES LIBRES (ADL) CUYA SALIDA PROPORCIONA AL RITMO DE LLEGADA DE LOS PAQUETES SUS DIRECCIONES DE MEMORIZACION EN LA MEMORIA TAMPON (MP).
