Abstract
A modem for network system which is mounted in an electric home appliance to communicate with an external service device, to which an additional modem may be connected, and to which one or more electric home appliances may be connected and an operating method thereof. The modem has a plurality of input/output ports, functions of which are changed using a switch so that an additional modem or an electric home appliance is connected to the modem. When two modems using the same interface are connected to an electric home appliance, connection of the modems to the electric home appliance is easily achieved via the existing ports without adding a new input/output interface to the electric home appliance. Also, when one or more electric home appliances jointly use a modem, additional connection of the electric home appliances is achieved using a switch without using an additional distributor.
