Perspective broadband access technologies over multipair telephone cables

In this paper the tendencies of development of fixed broadband technologies is considered. The perspective way of development of xDSL broadband access technologies is shown and the main problems of implementation of this way is identified. The “vectoring” compensation crosstalk method with parallel operation of transmission systems in the multipair telephone cables is considered. The xDSL-systems modeling at the domestic Tn type cables using the “vectoring” is completed and the comparison of the achievable transmission rates these systems without using and using the “vectoring” system is performed.
