<p>PURPOSE:To improve the efficiency by applying sub block division to transmission data so as to be set in a pay load, allocating a logic channel number to the divided blocks in the decided order and sending the data so as to transfer the data simultaneously through plural transfer paths. CONSTITUTION:A transmission terminal equipment 1 divides transmission data 40 into data blocks a, b of a prescribed size and transfers the block with a VPI/VCI different from each block. For example, the block (a) is divided into sub blocks so as to be set on a pay load of a transmission cell and applies coding to the blocks depending on the AAL in use and uses a VCIa to generate transmission cells a1, a2... and sends the cells via plural connections 31, 32. In this case, the transmission terminal equipment 1 allocates a logic channel number to each block in the order decided with a reception terminal equipment 2 in advance. The reception terminal equipment 2 references the logic channel number of the received ATM cells and links them in the predetermined order to compose the reception data 50.</p> |
