As a side issue, I've noticed I have two lines running into my house , one goes directly to a socket upstairs and the other line directly to the masters socket, I've noticed my cables are alot thinner than the other lines going to neighbours, is this because I have two lines coming in ?? Could these thin cables be the reason for my speech issues ??
No. The gauge of the conductors in the cable from the green cabinet to the pole will be a lot smaller.
