Every year or so my line gets so noisy that my internet connection fails. In the past this has cleared up after a few days. This time it's been bad for about two weeks and in the end I got my ISP to take action by ringing them on the land line (I normally use my mobile) and they couldn't make out what I was saying because of the noise. They've arranged for a visit from OpenReach (stupid name) on Monday morning. There are three telephone sockets in the house (each marked with the old 'T' logo from years back) and, looking round the outside of the house, I can see that they are connected by wiring that hasn't been fixed very professionally so maybe it wasn't done by, what was then, the post office. So, I suppose, the noise maybe because of this poor wiring. BTW the noise is bad on all three sockets including the first where the line enters the house. Anyway, my question. Where does OpenReache's responsibility end and mine begin? Am I likely to be faced with a charge if this wiring turns out to be the cause of the trouble?
