Abstract

PROCEDIMIENTO Y APARATO PARA EL ACCESO ALEATORIO MULTIPLE A UNA LINEA DE TRANSMISION EN UNA RED LOCAL PARA VOZ Y DATOS. EN CADA UNA DE LAS ESTACIONES (T1 ... TN) QUE INTERCAMBIAN INFORMACION EN FORMA DE PAQUETES A TRAVES DE LA RED LOCAL (RL), EL PERIODO DE ACTIVIDAD DE LA MISMA ES DIVIDIDO EN TRAMAS DE DURACION IGUAL AL TIEMPO TRANSCURRIDO ENTRE LA FORMACION DE DOS PAQUETES DE LA MISMA COMUNICACION. EN CADA TRAMA SE ASIGNAN A LAS COMUNICACIONES VOCALES INTERVALOS DE TIEMPO IGUALES A LA DURACION DE TRANSMISION DE UN PAQUETE, ESTABLECIENDO CANALES SINCRONOS. EN CADA ESTACION SE CONSTRUYE, TRAMA A TRAMA, UN MAPA DEL ESTADO DE LA OCUPACION DE LA LINEA POR PARTE DE LOS CANALES SINCRONOS.
