An ATM cell multiplexing apparatus comprising an AAL multiplexer for generating ATM cells from AAL type-2 user data, a buffer for cells to be sent for temporarily holding the ATM cells generated, and an ATM multiplexer for ATM-multiplexing ATM cells read out from the buffer for cells to be sent is configured. The buffer for cells to be sent comprises functions for discarding an ATM cell when the transmission wait time therefor exceeds a time-over period, and the AAL multiplexer comprises functions for giving priority to user data for which a higher quality of service is demanded than a discarded ATM cell, as the ATM cell to be generated immediately following the discard.
