why do I have a transformer wired to phone system?
I have two wires that are used coming in off the street (4 total). The other two are not wired. These 2 wires go to a junction block next to the electrical panel. There is a transformer plugged into an outlet there and the two wires from that go to the green wire pairs running through the house. There are actually only two runs from the junction block through the house. One for the upstairs and one for the downstairs. The low voltage is wired to both sets of green pairs. Why is there low voltage running through these lines?
