Just an update to say that an engineer turned up unexpectedly this morning about 8:30am after putting an oscillator on the line (made us jump given the phones were constantly ringing lol). Although the problem disappeared on Friday afternoon he still said there was a fault which needs resolving. So after two hours of testing and searching he swapped the wires round in the cabinet and the battery contact problem of 50v~ reduced to to about 5v-12v. My attainable rate has shot up from about 82/27 to about 94/29.5 on the HG612.
Anyway, he tried to call the special place (service center?) for resetting the DLM profile but he had no success as he required an OGA number or something. He suggested since I'm on a business service that I should be able to call BT Business for a reset with little hassle. I'll call the helpdesk in a minute and see if I get much luck, and edit this post accordingly. Thanks MHC for the help given, after clearing up the small confusion over me not mentioning I was business and not home
No luck, as far as they're concerned I'm getting slightly above the minimum I was promised, although my line can do much better.
