Abstract: PROBLEM TO BE SOLVED: To save switch resources and to enable another transmission function to be executed by continuously transmitting ATM cells to a processor link which is divided by virtual rout display. SOLUTION: A register part 302 picks-up the virtual route display VPI of processor routing information and transmits it to a memory part 303. The memory part 303 refers to a VPI value inputted from the register part 302 and outputs a processor routing bit map to a processor cell transmitting part 305. The processor cell transmitting part 305 recognizes the processor routing bit map inputted from the memory part 303 and outputs a reception FIFO selection signal for previously selecting the processor link to multiple processor reception FIFOs 306. When the processor reception FIFOs 306 are enables by the reception FIFO selection signal of the processor cell transmitting part 305, FOFOs 306 stores the output of the register part 302 and outputs it in a lower part processor link 308.
