Apparatus for controlling access gigabit ethernet System and method for accessing gigabit ethernet having them

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an access control apparatus for a local area network connection, and a local area network connection system and method having the same. The present invention relates to an output signal setting unit for outputting output signal information on the number of signals to be output by a plurality of cables; A symbol multiplexer for receiving the output signal information and multiplexing the symbol signals by the number of signals to be output to the cable to generate a multiplex signal; And a signal transmission unit for receiving the symbol signal and the multiplex signal and setting a number of valid ports for transmitting the input signals among the output ports connected to the cable, And a local area network connection system and method therefor. According to the present invention, it is possible to provide a maximum speed suitable for the required performance level, thereby reducing the number of lines required for providing the Internet service, and utilizing the remaining lines not used for signal transmission for other purposes. ; Gigabit Ethernet, local area network, UTP cable, multiplexing, demultiplexing
