How to Make a Telephone Cable - DIY Video

To get started, let's make sure you have the necessary tools:



You'll Need:
RJ11/RJ45 Crimp Tool
Bulk Cat3/Cat5e Cable
RJ11 6P6C Modular Plugs
Electricians Scissors
RJ11/RJ45 Cable Tester


Step 1) Strip off about 1-2 inches of the cable jacket, being careful not to cut the individual strands of cable


Step 2) Separate all 4 pairs of cable


Step 3) Cut off the brown pair, and line up the cables using the USOC wiring diagram. We will be using conductors 2-7, since this is an RJ11 6P mod plug.



Step 4) Cut the cables as straight as possible, leaving around 1/4" of cables


Step 5) Insert the cable into the modular plug. Keep constant pressure on the cable, to assure the pairs do not come out of order. Make sure to press the cable all the way to the front of the mod plug.


Step 6) Insert the assembly into the 6P slot on your crimp tool, keeping pressure on the cable. By pushing slightly on the cable towards your tool, you will reduce the risk of the cables backing out slightly. Squeeze the tool all the way, remove the plug and repeat the same steps on the other side.
