Im not on FTTC, on ADSL. 9km from the exchange. But Openreach replaced 3km of cable to our property where there were no other feeds and upgraded it from .5 to .9 gauge to up the BB speed from about .3mb to 2.5mb. Although beforehand there was a telephone fault on the line. But still I was suprised they replaced it at all. Although saying this, it took 12 ISPs, a letter to Ian Livingston, and 2 openreach area managers before they did it, and a lot of pestering. It took 6 months to fault find all 9km of the line, until they were happy they couldn't do any further. Think the total job cost was £92k. and the bugger is we still have problems with our broadband dropping out . probs think it's bull but there are people on this forum who can back me up.
I'm not calling you a liar, gouldew, but no ammount of 'chairmans letters' or visits from Openreach Managers is going to get 3Km of cable replaced. If that were the case, we'd all be writing letters, or getting into little gangs to apply pressure up the BT echelon.
There was probably far, far more to it than you are aware of ?? As you are very rural, the cable will most likely be at full capacity, as in no spare wires to add new circuits. Or, somebody coming off a DACS circuit (Splitter box) as they have applied for DSL ??
Even if there
was a PSTN fault, they will NOT, I repeat NOT just replace 3Km of cable for that. They will find the faulty section, cut it out, and replace with new.
As I say, I'm commenting in general terms here, not on your specific situation. But I reiterate, that you will not be in full possession of all the facts behind why they did what they did with 'your' feed.
