One of our customers has been advised that something called a "t-bar" (phonetic spelling, I or he may have misheard and I've probably mis-spelled otherwise anyway) will improve his ADSL connection.
Professor Google hasn't helped me work out what he is being told, does anyone here know?
No idea, but from a customer's point of view the best he can do to improve his connection is to fit an ADSL filter face plate from a reputable supplier, a BT I-Plate (or whatever it's called now) and then connect the modem directly to the master socket, which will filter out all the voice extensions in the building.
After that, assuming the modem isn't an issue (could try a few to be sure), there's pretty much nothing you can do but get BT OpenReach involved ... good luck with that. ;) I wouldnt bother unless you can look at the line stats and can prove that your connection is under performing - it's hard enough to get them to do anything even when that's the case ...
