Abstract: PROBLEM TO BE SOLVED: To economically process an asynchronous transfer mode (ATM) cell with minimum transfer delay by allocating the memory position of a time slot memory to the payload byte of an independent cell and adjusting the writing of payload data into the allocated memory position. SOLUTION: A communication exchange transmits/receives an asynchronizing signal constituted of the independent data cell having individual cell header and payload, which one of signal input/output ports 807-809 allocates to a communication channel. An exchange module processor 801 and a message handler 802 selectively control time slot mutual exchange 820 for setting a communication route between the communication channels. The memory positions of the time slot memories (data RAM) 830 and 831 are allocated to the payload bytes of the independent cells and a signal for adjusting the writing of payload data to the allocated memory position is generated.
