PURPOSE: An internet subscriber network system is provided to transmit a data signal by using a 10M ethernet, a 100M ethernet, a 1G internet technology without a digital signal manner, to switch an ethertnet packet from a switching node to a desired root to build a subscriber connecting network, so as to supply cheap and super speed internet services. CONSTITUTION: Community centers are connected to a gigabit ethernet port of an internet backbone network through a first ray path to directly transmit an ethernet packet, and supply a community information server and a routing function to support a logical segmentation of a subscriber group, then perform a switching for connecting remote node devices to the backbone network of the gigabit ethernet port. The remote node devices are connected to the community centers through a second ray path, and transceive a giga optical signal having a signal format according to an ethernet media connection controlling protocol. The remote node devices have transmitting functions of the ethernet packet, and perform ethernet switchings of central node devices to connect the central node devices to one of the community centers by a fast ethernet interface. The central node devices share a phone line of a subscriber house, and have phone-LAN modules transmitting phone signals and local area network(LAN) data signals. The central node devices transmit the ethernet packet by the phone-LAN modules at 10Mbps to perform a switching of the ethernet packet, and connect the switched ethernet packet through one of the remote node devices and one line of two-wire phone lines, four-wire unshielded twisted fair cables, 100MFX optical cables. A subscriber equipment is connected to one of the phone-ran modules installed to one of the central node devices to divide a transmitted signal into the LAN data signal and the phone signal, and transmit the ethernet packet, which is the LAN data signal, to a LAN card to transmit the phone signal to a phone.
