Method and arrangement in a digital subscriber line system
Abstract:
The present invention relates to arrangements and methods in a Digital Subscriber Line (DSL) system.The basic idea of the present invention is to reserve a first part of an available frequency band exclusively for vectored DSL transmission and reception.The remaining part of the available frequency band can then be used either for only standard non-vectored transmission or for both for vectored DSL and for standard non-vectored DSL transmission. Therefore, the present invention makes it possible to get the full benefit of vectored transmission, on at least the first part of the frequency band, even if the DSL vector system cannot handle all DSL modems.
Abstract(Chinese):

本发明涉及数字用户线（DSL）系统中的布置和方法。 本发明的基本思想是预留用于向量DSL传输和接收的可用频带的第一部分。 然后，可用频带的剩余部分可以仅用于标准非矢量传输，也可以用于矢量DSL和标准无矢量DSL传输。 因此，即使DSL矢量系统不能处理所有DSL调制解调器，本发明也可以在频带的至少第一部分获得矢量传输的全部优点。
