Telephone sets 2-1 to 2-n and computers 1-1 to 1-n are connected to a terminal board 6 via common home-side wires 9-1 to 9-n. This terminal board 6 has a structure in which telephone wires 14-1 to 14-n from a public telephone network 61 are connected thereto while the home-side wires 9-1 to 9-n branch off to a line concentration switch 7 therein and terminal-board-side splitters 13-1 to 13-n connected between the telephone wires 14-1 to 14-n and the home-side wires 9-1 to 9-n are disposed therein, so that the telephone sets 2-1 to 2-n can use a telephone service via the public telephone network 61 and the computers 1-1 to 1-n can perform high-speed data communication with the Internet 62 by a VDSL service using an optical fiber cable 10 via a router 8 connected to the line concentration switch 7.
