Abstract
A wireless LAN system uses a single wireless telephone line. When a telephone apparatus outside the network originates a call to the LAN, the system allows establishment of wireless telephone communication between that telephone apparatus and a slave communication device. Each transmission/reception device is controlled to switch between a first state in normal times in which a transmission/reception device of a master communication device is turned on and transmission/reception device of respective slave communication devices are turned off and a second state in which the transmission/reception device of the master communication device is turned off and only the transmission/reception device of any one of the slave communication devices is turned on.
