Zusammenfassung:	PROBLEM TO BE SOLVED: To easily change constitution and to completely protect secrecy in a trunk line by performing communication with a server through a main LAN from a terminal connected to a bridge device by the channels of respectively set different bands. SOLUTION: Plural bridge devices 1 use the channels grouped for mutually different frequency bands. A server device 5 sets setting data for specifying the channel usable by the respective terminals 4 to the bridge devices 1 to the control part 1b of the bridge device 1 through a specified channel. When the terminal 4 requests connection with the server 5, the control part 1b of the bridge device 1 controls a connection part 1c so as to connect the line of the low-speed LAN 3 of the terminal 4 requesting the connection to a cable modem 1a to which the channel specified by the setting data is set. For the respective terminals 4, a specified server 5 connectable through the bridge device 1 and the main LAN 2 is decided beforehand and the specified channel for that is set.
