PURPOSE:To make the amount of data communication uniform by assigning a low-speed channel to a high-speed side line with less data communication amount dynamically in assigning the low-speed channel to the high-speed side line. CONSTITUTION:When input data is incoming, the value of a data speed used in a channel is transmitted to an assigning circuit 103. The assigning circuit 103 adds the value of data speed transmitted from a registration line 101 to a smaller value at present point of time provided in adders/subtractors built in each of high-speed two lines and assigns the low-speed channel to the high-speed line. Moreover, a cancelling circuit 102 detects the end of input data, this information is transmitted to the assigning circuit 103 to cancel the assignment of the low- speed channel assigned to one of the high-speed lines and to subtract the value of the data speed of the channel from the adder/subtractor. |
