From your description and as you are using test socket it sounds like you have a high resistance fault so you need to phone 151 And report a phone fault with no mention of broadband. http://www.kitz.co.uk/adsl/connectionprobs.htm
Thank you so much for your help. Will this mean that I will have to get an engineer round?
Thanks for the help. I called 151 and they did the checks but it showed there was no problems with the line so we will get an engineer round when your offices are open. Or if you could arrange an engineer to come round, that would be even better.
I am it a customer like you and only BT employees are the forum mods. Just phone 151 again tomorrow refer to forum do high resistance fault. CS have a habit of not phoning back
Sorry. I mistook your for one due to your badge next to your name. Well thank you very much for taking the time out and helping me out.
as long as engineer managed to solve your problem
thanks for update
Noise margin was probably set too low at 3dB instead of 6dB.
