An asynchronous transfer mode (ATM) switching apparatus is provided in a communication network, and includes an ATM switch for switching a path for a cell. A control unit controls the ATM switch. A network interface board is installed in a slot to interface between the ATM switch and a communication channel for the cell. A server board is installed in a slot in which the network interface board can be installed. The server board receives cells from said communication channel through said network interface board and said ATM switch under control of the control unit to provide a service. The server board outputs cells corresponding to the service such that the cells are sent to the communication channel through the network interface board and the ATM switch under control of said control unit.
