Sorry for confusion, but I like bit about a new boy sitting a test. Countdown from 100 and you could be right.
The test was from ISP while thinking about fibre, and referred to copper line length.
I wanted to know what the difference of the two lengths represented in hope it'd guide in distance from PCP to premises.
DP Line Length Estimate: 2725 Metres
DN Line Length Estimate: 2818 Metres
2818-2725 = 93 cannot be to anywhere near me, as later test on fibre indicates PCP to premises is ~1000m.
From what I am informed is my DP is according to Google Maps about 120m.
All is now likely irrelevant, so if you want to ignore, please do so!
