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.
