Abstract
A method and apparatus for reducing crosstalk between digital subscriber lines includes: firstly, determining a parameter of VDSL (Very-high-bit-rate Digital Subscriber Line); secondly, determining frequency range of signal to be transmitted in the line and transmitting signal in the corresponding line according to the determined frequency range. This mainly means reducing or turning off the transmitting of the signal at a high frequency band and only using low frequency band for data transmitting in the case that the line parameter exceeds the predetermined threshold, so that crosstalk to neighboring lines is reduced. The present invention can effectively overcome the crosstalk against neighboring lines during the channel discovery phase of digital subscriber line and the transfer performance of the digital subscriber line in operation can be guaranteed. The present invention is realized based on the established standard, so the present invention is simple and easy to implement.
