Below is documented the procedure for wiring for making a telephone lead to connect a telephone to an RJ11 phone outlet plate.

 

To Make a Telephone Cable

Equipment needed

  • Roll of Telephone cable Cable (single or twin pair) 
  • RJ11 CRIMPING Tool
  • RJ11 Connectors * 2

Steps

  1. Using an RJ11 crimping tool remove the outer protective sleeve leaving around 25mm of cable exposed
  2. Fold over or cut off the extra e.g. the white/orange & white/blue cables
  3. Straight out cables into the required order - the convention is to use the 2 Blue/Orange wires for pin 2 & 3
  4. Again use the crimping tool to cut off the down the core wires to leave about 12mm exposed
  5. Push the cables into the 2 central RJ11 slots (will have copper pins)
  6. Use the crimping tool to crimp the connector onto the cable
  7. Repeat the same process for the other end of the cable.
