PURPOSE: A device for supplying a high speed internet service using a home phone line networking alliance(PNA) is provided to use a home PNA 2.0 having a maximum 10Mbps to downward and a 700m communicating range, to convert a pulse of a home PNA 1.0 signal having a maximum 1Mbps to upward and a 300m communicating range, so as to prevent communicating errors caused by a near-end crosstalk, and to keep a home PNA merit without a signal divider and a terminal matching unit. CONSTITUTION: Ethernet processors divide ethernet packets, and switch the ethernet packets. Downward home PNA processors convert transmitting packets of the ethernet processors into home PNA 2.0 signals. Upward home PNA processors restore a converted home PNA 1.0 signal received from a phone line into an original ethernet packet, and transmit the restored ethernet packet to the ethernet processors. Transformers perform an impedance matching of a phone line, and perform signal separations. Terminal downward processors(5-1-4,5-2-4) restore received home PNA 2.0 signals into the ethernet packets. Terminal upward processors(5-1-8,5-2-8) convert the ethernet packets into home PNA 1.0 signals to which a signal band is converted. Transformers(5-1-1,5-2-1) perform an impedance matching of a phone line, and perform signal separations.
