I've had a few problems with my phone lines and to cut a long story short, after many engineer visits, a BT Openreach engineer changed the pair at the pole of one of my lines, and then, when I thought that 1.5Mbps on a line which had a 37dbs downstream attenuation was fine, my sync speeds boosted to over 7Mbps.
So now is the issue for the other phone line - I have another phone line RIGHT beside the other one (being fed from the same exchange and pole) and it gets 1.5Mbps.
I've only bothered to come around to this now as I'm using this line more and it's very slow compared to the other line.
I've had a few engineers around and they are saying that they can't do anything (even though when I mention the line right beside the slow one can get 7Mbps), they say that it may be taking a different route.
I emailed Ian Livingston today and got a call back from one of his nice staff members.
He asked me if I was with a different ISP than BT, I said yes (ADSL24). He said that because it is a broadband fault, I'd need to go to adsl24.
I know rightly that if I go to adsl24, the same will happen and the engineer will come and say (oh, you'd need to book a telephone engineer for that, not a broadband one).
He's saying that under the service level agreement, if there's a problem with the telephone line, BT will deal with it... but seeing as it is not, they won't. He said he would do investigating but I get the feeling that is only going to be a line test which will come out negative for problems.
The last engineer said I was on the last pair for the pole so they'd need to get an underground team out if there was any more pair exchanges.
BT say that because it's a 'broadband fault', I need to deal with that specific broadband provider, however, with the last circumstance, I've ruled out all internal wiring issues & I definitely believe that if they change the pair at the pole, I'd get a good sync as noted with the last case.
Thanks for reading.
