That is your main BT connection and you don't own it or anything else until the first connection box in your house. If you want to change it you would need to get BT in to do it.
It's pretty simple to DIY though and you can sometimes get enough cable from the drop wire (the one that comes from the outside to the inside) to get it through the wall under the windowsill and then fit a recessed box in the wall with a cover plate. You'll have trouble getting BT to do it though or it will be expensive and you'll probably not find anyone else willing to do it. If you do it and screw it up (which is unlikely) BT will most likely charge you through the nose to fix it rather than take you to court.
Hard to identify the other wire but it might have been for a bell that rang for the whole house rather than individual telephones ringing or just an antiquated extension.

Hello, was wondering whether any of the thread experts could help me out. I am having some repairs done to my sash windows. One of the ones in the living room bay window has two cables going through it, which connect us to the internet. There's currently a junction box on the inside of the window, as you can see in the photos, which turns the two cables into one.
What I would like to do is replace the junction box with the smallest possible version that will do the job, drill a hole in the new windowframe, reconnect the cables and fill the whole thing to keep the weather out.
I'm happy with the drill 'n' fill aspect but not the electrical parts - anything I should look out for? Also, what's the thin cable likely to be doing - is it an earth?
Thanks
