Which boxes are useful? (What are they please?)
 

Would really appreciate someone's help please.
I'm doing up a flat and have come across these various things... Unsure if they're aerial boxes, stuff to do with satellites or what... To be honest my knowledge of TV/phone access is limited as I've only ever had virgin and then NowTV previously. Can I get rid of them? Are they any use? Which one do I need to keep or if someone comes to install NowTV/Virgin etc will they just install their own new one? Is there any benefit to these? Many thanks, Joy

First ones a Cable box so Virgin broadband and TV should work on it. 3rd is a BT box for phone line and BB middle box but not sure where does the cable go?

The cables that are running out of them just travel through the flat one is a dead end, from the first cable box. The wire from the middle photo looks a bit knackered, it disappears into a wall... Unsure where to to be honest. Would it be outside and up? Seems a thin cable from that one.
The third photo BT one has a doggy extension, can I just disconnect it, if I don't need it travelling to another room? Thanks so much for your reply!
