Abstract: PURPOSE: A port selection transfer logic is provided to simplify the configuration of a port selection transfer logic by installing a logic gate to transfer ports selectively and to cut the manufacturing cost by reducing the number of gate buffers to open and close the connection between a giga bit MAC and a 10/100M PHY according to signals generated from the logic gate. CONSTITUTION: A gigabit MAC(1) supports all 10/100/1000M bps. A 1000M PHY(4) and an optical connector(6) connected to the giga bit MAC(1) form part of a 1000M port. A 10/100M PHY(5) and an RJ-45 connector(7) connected to the giga bit MAC(1) form part of a 10/100M port. A logic gate(101) composed of an inverter(103) and an AND gate(104) is connected with the optical connector(6) and the RJ-45 connector(7) to receive signals transmitted from them. A gate buffer(102) is installed between the giga bit MAC(1) and the 10/100M PHY(5) to open and close the connection between them by signals generated from the logic gate(101).
