It's been sorted. It must have been something at the bottom of the road because nobody's called at the house.
It had been a continuous click about 3 times a second and the ADSL light on the router was off. It was also very annoying if you had to speak to anybody on the phone. When I first reported the fault the guy on the other end of the line had to call me back on my mobile because it was so bad.

Hmm, maybe it was something else. I've just had a BT engineer turn up at the door looking to fix my problem.
