so basically I could run a cable from the outlet of the first connection box to the master socket, eliminating the other 2 connection boxes, or could loosen one of cables in one of the blocks and report it as an intermittent fault and get them to sort it out.....
Well the second way "might" work and I say might and is a bit iffy at the same time.
And the first way is a bit iffy, due to only BTOR are allowed to touch that wiring.
I have been lucky in the past when I re-did the entire wiring from the BT80 box and relocated my Master Socket.
Which BT were fine with for those times after a few mins explaining things to them and due to the line of work I did at the time.
I was then told not to touch it once I finished it, which I haven't touched it since.
Its all down to who you speak to, same with the engineers.
Also when my FTTP was installed here FVA (Fibre Voice Access) wasn't ready at the time of them doing the internal work so they left me the cable and said when its live just remove the copper line and connect the new wires going to the ONT (Modem).
So its yes and no to you are not allowed to touch their side of the wiring, maybe I was lucky the 3 times I touched the wiring.
TBH, I would wait to see what other people say on here before you go down the route you choose, my advice might be a bad one for you to go down and I was possibly just lucky.
