Apparatus for reducing crosstalk interference due to tdsl based t-lan tranceiver

PURPOSE: An apparatus for reducing crosstalk interference influence by TDSL(Time-division-duplex Digital Subscriber Loop)-based T-LAN(Telephone wire-Local Area Network) transmitter is provided to reduce babble noise generated from a different xDSL(x-Digital Subscriber Line) unit housed in the same cable by limiting a signal power spectrum. CONSTITUTION: An input terminal(602) connects an output terminal connected to a subscriber line from an office side transmitter or subscriber side transmitter to a crosstalk interference reducing unit(6). A low-pass filter(604) passes only a main signal of a TDSL-based T-LAN transmit signal inputted to the input terminal(602) and cuts off an unnecessary harmonic component. An output terminal(603) connects the signal which was passed by the low-pass filter to the subscriber line.
