g.fast uses higher tones which are weaker. It has much more tones available but those tones drop off quicker over distance,
for a 67 low estimate on 'clean' you dont need to be on top of the cabinet, a line around 300-400m should get that estimate for FTTC.
Given openreach I think set a limit of 350m for g.fast I am surprised the line has g.fast marked as available as I am guessing its a bit over 350m. Have openreach decided to push it to longer distances?
