PROBLEM TO BE SOLVED: To improve the performance of data transmission from a peripheral station to a central station by improving a line access system for multiple access when peripheral stations access the central station by using one satellite line on a time-division basis. SOLUTION: A terminal monitor part of a peripheral station T1 recognizes that a large amount of data are transferred by file transfer from a data terminal connected to its station to a host terminal on the side of the central station C. Then when starting data blocks A to D are generated, a packet A is transmitted by a slotted alopha system and a connection reservation request is added thereto. At this time, for example, 2 is requested as the number of reserved slots of each frame. two reserved slots each continued to be allocated to frames after a frame 5. Therefore, data after data E generated successively at the peripheral station T1 can be sent out to the reserved slots. |
