It works on chickenwire too, VDSL not so much. Back in the day when i installed internet lines customers with mandatory ISP service requirement by the gov with absolute shit outside or inside wiring got ADSL, forward-error-correction magic. VDSL was a lot more sensitive.

In some cases I would be forced to use a cat-5 or even poor quality cat-3 where two pairs are for ethernet , one pair for A/VDSL and the blue pair for voice/POTS (voip to pots converted)
