I just went to put my new 4 conductor, 2 line wall surface mount jack box on the wall, and ran smack into a new problem.
I thought I had it down pat: two pairs of wires to deal with. one pair would be red and green, the other black and yellow.
What I found when I got in the old box is:
1. two four conductor jacks. One phone number to each of the jacks.
2. A cable coming in from beneath the house with six wires: black, yellow, green, white, red, and blue
3. six pairs of terminals.
4. The six wires from the incoming cable go to the terminals.
5. There are six wires going to each of the four conductor jacks. Each jack has the black, yellow, green, white, red, and blue wires going to it.
Anyway, to the old jack box with my new single 2 line, 4 conductor jack box do I forget about the Blue and white wires, and just use the red-green as one line, and the black-yellow as the other?
Sounds crazy---but there it is.
Oh yeah---will any of those wires bite me? I remember a few years ago when we had a lot of hurricane damage, I found out the hard way that some phone lines can bite. Our yard was ripped up where big trees had gone down, and the phone line broke in several places. The phone company said two months to get someone out and fix. I took jumpers and pieces of wire to get 'em going again. I think I recall some combination of wires had around 50vdc
