METHOD FOR REDUCING NOISE OF LINE FOR XDSL COMMUNICATION, TERMINAL DEVICE OF LINE FOR XDSL COMMUNICATION, CENTRAL TERMINAL FOR XDSL COMMUNICATION, RELAY DEVICE OF LINE FOR XDSL COMMUNICATION AND XDSL COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method by which radiation field from a telephone line associated with DSL communication can be reduced; and to provide a terminal device, a central terminal, a relay device and an xDSL communication system for the method. SOLUTION: A cable 1 comprises several bundles of telephone lines each of which is composed of two metal wires. Two metal wires of a telephone line 1-2 of the cable 1 which is not used are connected through a resistor R1 at one end or at both ends. COPYRIGHT: (C)2005,JPO&NCIPI
