At work we've got a cable comes out of the ground outside and into the building. It disappears behind a wall so can't really be easily traced. The cable says fibre optic on it and has a picture of a telephone on it too but BT (who provide our phone line and internet) say it's nothing to do with them. Any ideas?
As far as I know we've never had any supplier other than BT but you could be right. Looks like I'm doing a bit of literal digging tomorrow doesn't it
Chances are it's an old line that's potentially been terminated, you might have a white master socket somewhere in the building with no connections and it might have a number on it which you could trace back to find the provider.
