  • Information transfer apparatus having control unit with BTL transceiver applying transmission enable signal inputted from ethernet processor module through backplane to control unit
    Patent number: 6347345
    Abstract: The present invention relates to an ATM-LAN(Asynchronous Transfer Mode-Local Area Network) switch, and in particular to an information transferring apparatus between processors of the ATM-LAN which is capable of efficiently performing an information transfer between a plurality of processors which perform an information transmission and receiving operation through a backplane based on the Ethernet protocol. The information transfer apparatus between processors of an ATM-LAN switch according to the present invention is capable of implementing an efficient information transfer between processors by providing a backplane sub-board for thereby checking an information transfer state between the processors without using a large number of devices for an Ethernet communication. In addition, it is possible to enable a stable information transfer between processors in the case of a hot swap and dual operation by providing a control logic to the backplane sub-board.
