Can someone explain this wiring?
I'm trying to make sense of the networking wiring that was already in place when we bought our house. The previous tenants had cable internet but we had uverse installed. Coming out of the wall plate are 2 jacks, a green jack that connects to the modem/router and a white one that I think is for phone service (we don't have a home phone). From the bottom of that same faceplate are a brown, brown/white, green and green/white set of wires that go into a small box just beneath the faceplate. That small box (I don't know what to call it) has an rj45 jack that connects to the router. Inside the wall this small box connects to a panel in the basement where it is connected to a switch and splits off to security cameras, tv, etc. I've attached photos of the set up Sorry about the picture quality, but we have an enormous entertainment center in front of it that I can't move.
Here are my questions?
1) What are the brown, brown/white, green, green/white wires for and why do they go to that box below the faceplate?
2) Before the cat5 connects to the switch in the basement, it again separates out into blue/orange and brown/green (see picture). Why? The blue, blue/white, orange, orange/white split off into their own cat5 cable and go...... somewhere. I can't trace it once it goes into the ceiling. I don't have any phone or ethernet jacks anywhere in the house that I've found. Where might this go?
Thanks, this is driving me crazy and my wife is not going to be happy if I start putting holes in the walls to figure it out.
