Did you try plugging a phone into the filter? I just wonder whether the socket is properly wired. As to support, if the line is stable, it's a case of asking them whether they can get BT to lower the target margin. BT are not always co-operative, but it's worth a try.

No, I didn't plug a phone in, but I've had another thought.  The very first 2700 I had did the same thing - power light on, but otherwise dead.  As I didn't want to scramble round the back of the PC, I used the power adapter from that old 2700 for this test, so maybe it's the power adapter that's faulty, and I may have another working 2700.

A distinct possibility.
