The sending/receiving unit of an STM switch is provided with a converting circuit for converting time division multiplexed frames of an STM network to cells of an ATM network and a converting circuit for converting cells of an ATM network to time division multiplexed frames of an STM network. The STM switch time division multiplexes data from terminals, converts the time division multiplexed frame to cells and sends the cells to an ATM switch. Cells switched by an ATM switch and sent to the STM switch are converted to time division multiplexed frames by the STM switch, whence the frames are sent to prescribed terminals. |
