<p>PROBLEM TO BE SOLVED: To simultaneously shape a virtual channel(VC), together with a virtual pass(VP) and also to prevent erroneous setting of time by inputting plural VCs to a single input line and smoothing the amount of information that flows on a specific path to multiplex plural inputted cells and to transfer them. SOLUTION: A VC timing discriminating part 100 simultaneously smoothes a cell to which a virtual channel identifier(VCI) and a virtual path identifier(VPI) which are supplied a cell number counter 45 in a buffer separately added and discriminates an output enable time in the virtual channel, and a VP timing discriminating part receives an output of the part 100 and discriminates the output enable time of a cell that has a VPI. A read control memory 60 controls the counter 45 in the buffer and performs address read control of a shared cell buffer 40.</p> |
