Controlling Power according to Connection Distance

The distance of connection from switch to VDSL line may vary according to each VDSL
port. If same power is supplied to different connection distance, the power is larger than
power supplied to line connected to CPE far from switch. It may cause interruption in the
line connected to CPE far from the switch. You can control supplied power according to
distance to prevent too large power supplied to VDSL line.
