1: What does it cover and what doesn't it cover?
My understanding is that it covers fault resolution for house wiring from the demarc and onwards inside. Is this correct?
Does this mean it doesn't cover exchange > phone line > demarc fault resolution, which you would still get for free even if you don't pay wiring and maitenance..
Is this a correct interpretation?
2: Did you know it's optional, do you pay it?
I've considered cancelling the extra fee a few times in the past but I either didn't bother or wasn't sure about my understanding of what it covers.
I was just comparing pricing for phone and internet pricing for a few ISP's for my usage and noticed some providers hide the cost in tiny text and I figured it was time to open the debate again and improve my knowledge too.
