The achievable rates of the G.fast transmission systems operating over a TPP type multi-pair telephone cable and covered with a «vectoring» crosstalk compensation system are defined. The estimates of the throughput capacity of the G.fast transmission systems are given depending on the quantity of mutually influencing transmission channels and parameters of multi-pair telephone cable.
