Thanks for the responses everyone.

The grey cables are connected to the white wire with what look like wire nuts (but appear a little different) and also the screw terminals if i remember correctly but will take a photo and post again.

I left out some detail last time - the white cable leading from the mast outside the house in to the master socket also branches off 'en route' to the master socket via little junction boxes which lead to other phone sockets around the house, some for the phone and some for a now broken defunct internal comms system (the house has 3 levels so clearly installed to avoid screaming at each other from 2 levels away), so I was surprised that the grey cables would also be extension sockets.

Will post a pic soon as my rambling is probably just confusing things for those in the know.

Also does anyone know if I get fibreoptic put in - will this likely just come from the cabinet in the street to my master socket via the wiring that is there already, or will a new line be installed? will I get phone functionality as well as internet via this fibreoptic line?

Cheers
