<p>The present invention discloses a method of implementing a long range very-high-rate digital subscriber line (VDSL), comprising steps of: defining a frequency band of 0.025MHz~0.138MHz in VDSL frequency bands only to be an uplink frequency band (USO), and combining the uplink frequency band with the rest frequency bands into long range VDSL frequency bands modes, performing an increment-by-frequency and increment-by-rate training, and setting up a link at a high transmission rate for a short range and a link at a low transmission rate for a long range.</p> |
