Terminating voice and data network cables is done in two ways. Connecting the individual conductors to the panel with a punch-down tool accomplishes termination on a punch-down or distribution panel. This method is also used for data jacks. Terminating the male ends of data or patch cables is performed with an RJ45 crimping tool. This tool presses the contact points of the individual pins into the conducting wires of the data cable. At the same time, it crimps the open end of the plug firmly against the cable sheathing to act as strain relief, which prolongs the life of the connection.

Use the cable stripper to remove two-inches of the outer jacket from the end of the cable.
Untwist and separate the individual conductors.
Arrange the conductors in the desired order.
Trim the ends of the wire evenly to within 1/2-inch of the outer jacket with electrician's scissors.
Insert the conductors into the RJ45 plug. Push the wires into the jack until they reach the end of the slots in the plug. When you are finished, the outer jacket of the cable should at least 1/4-inch inside the opening of the plug.
Insert the RJ45 plug into the die (opening) of the crimping tool. The die is shaped like a jack so it will only fit in the correct position.
Squeeze the handles of the crimping tool together firmly.
Release the handles of the crimping tool and remove the jack.
Tips and warnings
- Electrician's scissors are made for cutting and stripping small-gauge wire. Using sewing scissors or office shears to trim wire will ruin their blades.
- The order of the conductors in your RJ45 plug will depend on the application. T568B is the most commonly used standard for Ethernet connections. The order of the conductors for this standard is: white/orange, orange, white/green, blue, white/blue, green, white/brown, brown.
