Abstract

SISTEMA PARA EL CONTROL DE TRANSFERENCIAS DE DATOS ENTRE UNIDADES TRANSMISORAS/RECEPTORAS. LAS UNIDADES TRANSMISORAS/RECEPTORAS (2-1, ..., 2-1, ...) CONECTADAS POR LA VIA COMUN (1) COMPUESTAS DE VARIAS LINEAS DE SEÑALES, A UNA UNIDAD DE CONTROL DE VIA (3), CUANDO QUIERE TRANSMITIR DATOS, EMITEN UNA SEÑAL DE SOLICITUD DE TRANSMISION QUE, RECOGIDA POR A UNIDAD DE CONTROL DE VIA (3), LA PROCESA Y DEVUELVE UNA SEÑAL DE PERMISO, CONECTANDO LAS UNIDADES TRANSMISORAS/RECEPTORAS DESEADAS, TERMINANDO LA SEÑAL DE PERMISO EN RESPUESTA A LA GENERACION DE UNA SEÑAL DE FINAL DE TRANSFERNECIA DE DATOS.
