Got a word from my friend who’s a sparky, that if I want, I can attatch RJ45 plugs on the ends of the cables running into the junction and then run the cables down my wall into a switch in my office. Would that work?

I would call it a Temporary permanent fix.

Well, aint much of a picture to really get a good idea. But that’s a punchdown block for CAT5. My guess would be it was used to extend a run, or repair a run that got cut- just a really ugly job of it. Looks like there’s a white wire there as well at the edge of the photo, tho…so 🤷 Gonna need some better pictures if you want a good answer.
