Looks like it came from this page:

VK3FS also has reference to it here:

Love this quote:
"Under normal conditions, this overlap in spectrum is not a concern. VDSL2 signals should not interfere with amateur radio signals as they are carried over copper wires and transmit at very low power. Maximum VDSL2 transmission is around 28 milliwatt spread across the spectrum between 25 kHz and 17.6 MHz, and microwatt levels into the amateur radio bands themselves. With wellbalanced twisted pair copper conductors, the power carrying the VDSL signals remains nearfield confined to the tight vicinity around the twisted pair cables and will emit little signal into the surrounding environment."
Tell that to the many Radio Amateurs that experience this issue.
