Hi, I was wondering if someone could explain this weird setup for a phone jack in one of my bedrooms. The wall plate has what looks like quad wire coming out from behind it (pinched between the drywall and the edge of the plate) and this cable in turn goes to a wall wart plugged into an outlet with two screw terminals on the underside. One screw has the red wire, the other the green wire. Is this some sort of alarm circuit? My house was built in 1976, FWIW.
