When I lived in the UK, dialling 17070 from a BT line would access their line testing software. I've no idea if it still does. Used to be able to give you reflectometer (line length) measurements, and any short circuits etc.
*cough* I'm sure members of the public aren't meant to use it though! Dan. -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
