PURPOSE:To transmit the data block in bit unit parallelly by using a plurality of lines, when a plurality of lines are used to transmit data in high speed to one communication party. CONSTITUTION:The transmission data from the communication control unit 1 is converted parallelly in bit unit from the serial parallely conversion circuit 42 and stored to the transmission buffer sequentially bit by bit. After that, the timing pulse in synchronizing with the transmission speed of the transmission line 3 is fed from the transmission timing line 41 to the transmission buffer 43, the bit data in the transmission fubber 43 is fed to the modulation and demodulation unit 2 according to the said timing and the data is parallelly transmitted to the opposing communication control unit not shown via the transmission line 3. On the other hand, the data received from a plurality of modulation and demodulation unit 2 is respectively stored to the reception buffer 46 in bit unit. The bit data of the reception buffer group 46 is converted in bit serial. |
