PURPOSE:To omit the sequence control corresponding to channel by adding a transmission sequential number to all unit data transmitted to plural channels at a transmission terminal and chekcing the sequence number of all the unit data at a receiving terminal. CONSTITUTION:A single channel comprising channels L11 and L12 connecting the transmission terminal and the receiving terminal and a single channel comprising single channels L21 and L22 are accommodated directly in a multichannel control section MLP not through a single channel control section. A series of serial number representing the sequence of transmission is added to all the unit data transmitted to plural channels at the transmission terminal. The receiving terminal checks the serial number added to all the unit data reaching from the plural channels. |
