Such high data-rates are achieved by transmitting at frequencies up to 30 MHz. Unfortunately transmitting at such high frequencies over twisted-pair leads to strong crosstalk between the lines. 
To address this issue crosstalk cancellation and precoding were developed, techniques known collectively as vectoring. The ITU is now… CONTINUE READING
