The order of colors for an RJ11 cable


I am trying to setup my new DSL modem and to save $100 a told AT&T that I would install the modem my self. The installer left open the box on the side of my house so that I could connect in, but I can't seem to get the coloring right on the phone line I bought to put an end on it. The box on the side of my house that I'm connecting into has open the black and yellow slot for me to pull data in. When I create the other end that plugs into the modem, I use the following color order:

Green  Red  Black  Yellow

That doesn't seem to work, so am I just supposed to put black and yellow together in the center or do I have the order wrong.

I am using phone line to do this, not CAT5. I'm also not sure if this was the place for the question, but I figured that it was probably the most likely to give me an answer.

The correct order is Black, Red, Green, Yellow. It's important to remember that RJ11 has 6 pins, and you are using the middle four.
