Where do all these wires go? It’s a tangle of colored wires coming from somewhere and going somewhere. They are all part of the legacy system affectionately known as POTS, Plain Old Telephone System. Your landline phone (if you still have one) is literally connected by a line (a wire) that runs along the land to other wires that connect to other phones..

I’ve wired phones in my house. There are only a few wires and it took me a while to figure out which ones go where. Try figuring out this spaghetti.
