Recently I had ATT Uverse installed and came to the situation where I need to run a telephone line and an ethernet cable from one side of the room to the other. So here is my little simple solution.
A little background information first. Ethernet twisted pair cables have 4 sets of twisted pairs. A network card and switch, router, hub, etc only use 2 pairs. A telephone connection only requires 1 pair for a single line and 2 pairs of course for 2 lines. So this project capitalizes on the 2 unused pairs by the computer, and uses them for telephone connections.
Here are some of the materials I used.
1 RJ-11 Keystone Jack, 2 RJ-45 Keystone Jacks, and some Cat 5e
A standard punchdown tool to secure the connections.
And here is the diagram I put together to show how they are wired.
The Keystone jacks for the RJ45's will usually have 2 sets of color coding on them, for 2 different cabling standards. 568-A and 568-B. For this project I am using the color codes for the 568-A scheme.
Now to start the actual work..
First I took a section of Cat5e and striped off about an inch and half of the outer blue jacket.
I then untwisted the pairs and punched all the wires into a single RJ45 Keystone jack.
Notice the word "CUT" on the tool. That is to indicate that it will cut on that side of the tool.. so always make sure that is facing outwards on a keystone jack.
Here its with all the wires punched into place.
Snap the covers on and it almost looks pro
Next I stripped off about 3 inches of the blue jacket of the opposite end of the cable.
I then untwisted the pairs so that I could split them between the 2 jacks.
I used sections of the jacket that I stripped off to separate the 2 bundles.
After they were separated, I just followed my diagram to attach the RJ-11 for telephone and RJ-45 for ethernet to the separated bundles .
And here is the finished product ready for its twin to be made.
Once the first one was complete is was a snap to build the second one.
Now I can use any patch cable between these 2 "dongles" and pass both telephone and ethernet where ever it may be needed.
Hope some of you may find this useful in the future.
