Every house has a telephone box, or also known as a Network Interface Device. With this telephone box, it does not mean that the telephone line in the house will be active by itself. It is very important to connect the telephone line from inside the house to this telephone box in order to have an active telephone line. Configuring your own landline is inexpensive and legal. No special permits or inspections are required, because the telephone cord that runs from the telephone box to the house is yours. Setting up your phone on your own can save you a lot of money compared to asking the telephone company for a technician to do the job.
Step
Step 1. Look for the Network Interface Device box which is outside your house
This box is gray or dark brown with a size of approximately 20cm x 30cm. Network Interface Device box is a box that connects the telephone network from the telephone company with the telephone network that will enter the house.
Step 2. Open the telephone box section where it says “Customer Access”
You will see a modular plug as well as a pair of screws. This plug has the same shape as the telephone wall outlet in your home, which is the place to connect the telephone cable in the house. Each of these modular plugs will be connected to the telephone line from the telephone company that comes into your home. The pair of screws that come in the case of the phone are red and green. This screw is where your new telephone line will connect to the telephone company's network.
- Before starting to set up the phone, first disconnect the telephone line from the telephone company that is connected to the telephone box. This step is just a precaution, which will cut off the electricity from the telephone company (the voltage here is very small, but can increase when a call comes in). After all the configuration process is complete, don't forget to reconnect the telephone company line that was disconnected in the first step.
- The red and green screws indicate what color wire needs to be connected to the phone case.
Step 3. Purchase a landline cord at a hardware store
Use only round phone cords.
Using cable pliers or scissors, gently cut the cable shield until 2 pairs of insulated colored wire are visible. The first pair of wires are red and green (used for line 1), and the other pair of wires are yellow and black (used for line 2 in the future). The length of the exposed wire coming out after being removed from its insulation is about 1 cm
Step 4. Open the telephone outlet in the house that will be used to connect to the new telephone line
Use a flat or negative screwdriver to open the telephone socket. Once open, you will see the cable configuration in the telephone socket.
- Inside the telephone socket, you will find 4 colored wires: red, green, yellow and black. Each wire is connected to one screw. Using a screwdriver, gently loosen each screw so that you can remove the wire attached to the screw.
- Gently peel off about 1.3cm 1⁄2 inch (1.3 cm) cover each wire, just as you did with the previous phone cord. Connect the wire from the telephone cord with the wire from the telephone wall socket by wrapping one wire around the other. Connected wires must be of the same color. Once connected, wrap the wire connection around a screw that is the same color as the wire, then tighten the screw.
Step 5. Look at your house plan and determine the best way to pull the new wires from inside the house to the telephone box outside the house
Step 6. Make a hole in the outer wall of the house where the wires will pass through the wall
Step 7. Push the phone cord from the telephone wall socket into the hole you just made, then pull the cord out of the hole
Run the cable through the house all the way to the Network Interface Device box.
Glue the wires on the outside wall of the house. Glue the cable to the wall using special telephone cable staples every 15-25 cm
Step 8. Make a hole in the thin circle at the bottom of the phone case cover
This thin plastic can be punched using a pen or pencil.
Pull the wire through the hole, and thread it through the door hinge on the left side of the phone case door to keep the wire in place. Pull the wire from behind the door hinge so that it can be connected with the red and green screws. Loosen the screw by one turn of the screwdriver
Step 9. Remove about 1 cm of insulation from each wire
Step 10. Wind each wire clockwise between the screw and washer, so that the red wire is connected to the red screw and the green wire is connected to the green screw
Tighten each screw to lock the wire in position and reconnect the modular plug into the socket. Close the phone case cover and tighten the screws.
Step 11. Reconnect the telephone network from the telephone company to the socket you disconnected in the first step
Call the local phone company and ask them to activate your phone.
Tips
- If your landline has not received maintenance from the telephone company for a long time, it is likely that the telephone box you have is an older type and does not have a Network Interface Device. The old telephone case was simply a plastic or metal cover that was attached to the telephone network box to protect it from the effects of the weather. If you do have an older version of the box, contact the phone company. They will come to your house and replace it with a Network Interface Device box at no charge.
