So my girlfriends house is wired for Cat5e in each of the bedrooms (total of 3), and 1 in living room. The drop points for the wires are in the basement. Upon going to the basement I found 4 terminated Cat5e cables and 4 terminated coax cables. There was also 1 non terminated Cat5E cable and one non terminated coax cable. I'm assuming the non terminated coax is the wire from the outside of the house. The thing I can't figure out is what is the 5th non terminated Cat5e cable for?
