PURPOSE:To prevent the occurrence of delay without the supply of basic clocks. CONSTITUTION:A synchronizing cell issued by a synchronizing cell transmission control section 310 on the transmission is multiplexed at the constant cycle and transmitted with signal cells. A synchronizing cell reception control section 620 adjusts the cell distribution operation based on the storage state of the synchronizing cell in a cell distribution section 600 on the reception. A variable speed decoding section 200 adds and deletes the repeating patterns of the repeating pattern section in the original signal when decoding the variable speed. Thus, the synchronization between communication terminals opposite asynchronously through an ATM circuit 40. |
