How to wire a multi line phone system?

Knowing how to set up a multi phone system can improve your technical skills and save you some money. To set up your multi phone system follow the following steps:

  1. Unplug the modular jack for every phone line connected to the Network Interface or NID. The NID is the plastic junction box placed on your property by the local telephone organization; it is positioned on an outside wall of your home or office building. The junction box links the incoming lines from the telephone organization to your inside lines and then to your telephone. To situate the junction box, follow the telephone cable that runs from the utility pole on your property. 
  2. Feed a CAT-6 cable via the rubber grommet at the bottom of the NID and pull it up into the junction box. Strip down 2 inches of insulation from the end of the cable using your diagonal pliers. Straighten out the exposed twisted wires and strip ½ inch of insulation from every wire, using a wire stripper. 
  3. Loosen the pairs of green and red terminal screws inside the NID using a screwdriver. A telephone line requires two wires so as to work, so you will need a green terminal screw and red terminal screw for every incoming line that wants to hook up. 
  4. Hook every wire clockwise around its corresponding terminal post and tighten every screw. For a multi-line phone system with three incoming lines, for line one, link the blue with the white wire with the blue stripe to the green screw. For the second line, connect the white wire with the orange strip to the green screw and the orange wire with white to red screw. When it comes to the third line, connect the white wire with green to the green screw and the green wire with white to the red screw. 
  5. Run the CAT-6 cable in your office or home and route in the wall nearest to where you intend to place your multi-line phone. Use cable staples to fasten the telephone line to the baseboard but do not place the cable parallel to a power line. 
  6. Route the cable into an outlet box mounted on the wall. Measure off one extra foot of wire and cut the cable square. Strip off two inches of plastic insulation with diagonal pliers. Straighten the exposed twisted wires and strip off a half-inch of insulation from every wire using a wire stripper. 
  7. Loosen the terminal screws behind the faceplate of an RJ-25 jack. Hook every wire to a terminal post as outlined; for; line 1, blue wire with white stripes to red terminal screw and white wire with orange to the black terminal screw. For line three, connect the green wire with the white terminal screw and the white to the white wire with green to blue terminal screw. 
  8. Tighten all terminal screws to safeguard the connections. Mount the jack to the telephone outlet box using the screws supplied with the jack. Go to the NID outside your home and plug in the modular connectors to complete the connection to your indoor phone jack. 
  9. Plug a multi line telephone set into the new RJ-25 jack. Press line 1, listen for a dial tone,l, and place a call to test the line. Test the other phone lines in the same way.
