Firstly if this post isn't in the right category, I apologise and please move to where you see fit. Secondly if my series of questions have been answered elsewhere, please feel free to link me :)
Now let's get on with the questions. Firstly, I wish to rewire a new phone cable from the external box (I have an overhead phone line) to a newly installed phone jack in my home. I am capable of installing phones jacks and daisy chaining them etc. However my first questions is, is it possible for the average person to open up the little termination box (on the roof) and install a new cable from it? Has anyone been able to successfully do this or is this something you get an electrician in to do? (If it's easy to do, does anyone have any online tutorials I could take a look at?)
My second question is I have briefly heard people talking of an internal (inside the wall/roof) filter/splitter, which replaces the little filters that telecom provide which plug into the wall. I've heard that these can potentially increase your connection quality. What are the exact name(s) for these devices? Are they easy to install, or again, is it something you get an electrician in to do?
My ultimate goal is to replace my home's 30+ year old wiring and potentially get faster download/upload and a lower ping. And ultimately lower my attenuation for when/if I get VDSL (I am out of coverage for the first 3 years of Fibre ).
Thanks in advance for any help!
