Extended T1 from Cat 5 Keystone to Patch Panel

Here is a way to extend a T1 from a smart jack to a patch panel. I personally recommend dropping another data run for this, but if you don't have that option here is a set up you can use.

Material Needed:

4 patch cables or RJ45 Standard Straight-Through cables
2 Cat 5e Snap In Jack (Keystone)
1 Wall Mount Cat 5e Keystone Jack

Since you are going to use all the pairs in the cable you might need to disable the current T1 extension to make this work. I will use the 568B standard and Leviton R24-5G108-RV5 CAT5e Jack for this example.

First pair for the existing T1 will be (Blue - Blue/White) ~ (Orange - Orange/White). This pair will run to the same colors on the keystone. Punch this first pair down on the Blue/White - Blue - Orange/White - Orange on the patch panel.

The second T1 will be punched down on the keystone a bit differently. Start by punching down the Brown pair. With Brown going to the Orange and Brown/White going to Orange/White.

The Green pair will go Green/White to Green/White (Pin 3)and Green to Blue (Pin 4). Here is a diagram of the Keystones and the wire assignments below:

You can test your pair now by connecting a patch cable from the jack to the smart jack. If everything is connected properly you will see all green lights on the smart jack.

This now has to be terminated at the patch panel. Punch all 4 pair down the same way on different ports.

Here is a diagram of this pin out:

Now that you have both T1's extended on one Cat 5e cable you can now use the patch cables.

Plug the cable into the wall mount jack and insert the other end into the smart jack RJ45 port. Back at the patch panel you will plug into your assigned port with one end and into the appropriate port at the router.

On the smart jack you should have all green lights and on the router you should see the carrier detect (CD) light as green.
