There are two main types of telephone jacks: RJ-11 and RJ-45. RJ-11 jacks are the most common type of telephone jack used in residential homes and small businesses. They have four conductors, which are used to transmit two telephone lines. RJ-45 jacks are used for Ethernet connections and can also be used for telephone connections. They have eight conductors, which are used to transmit four telephone lines or two Ethernet connections.
| Type | Number of Conductors | Usage |
|---|---|---|
| RJ-11 | 4 | Telephone lines |
| RJ-45 | 8 | Telephone lines or Ethernet connections |
Choose the Right Telephone Jack
Finding the Right Jack
Consider the type of telephone you have and the features you want in a telephone jack. Here is a quick guide:
| Type of Telephone | Recommended Jack |
|---|---|
| Standard landline | RJ11 jack |
| VoIP phone | RJ11 or RJ45 jack |
| Cordless phone | RJ11 or RJ45 jack with a base station |
Understanding Telephone Jack Types
There are two common types of telephone jacks: RJ11 and RJ45.
**RJ11:** This is the standard telephone jack used in most homes and offices. It has four wires and is typically used for landline telephones.
**RJ45:** This is a larger jack with eight wires. It is often used for VoIP phones, network connections, and other devices that require more wires. RJ45 jacks are backward compatible with RJ11 connectors.
Identify the Existing Telephone Wiring
Once you have determined the location of the new telephone jack, you need to identify the existing telephone wiring. This can be done by following these steps:
1. Locate the Network Interface Module (NIM)
The NIM is usually located in a central location in your home, such as the basement or attic. It is a small box that contains all of the telephone and data connections for your home.
2. Find the Telephone Line Terminal (TLT)
The TLT is a small, rectangular box that is connected to the NIM. It has two or more RJ-11 jacks, which are the standard jacks used for telephone connections.
3. Disconnect the Existing Telephone Wiring
Disconnect the existing telephone wiring from the TLT. You will need to use a screwdriver to loosen the screws that are holding the wires in place.
4. Identify the Wires
Once the wires are disconnected, you need to identify which ones are the telephone wires. The telephone wires are typically twisted together and have a white or black insulation. They may also be labeled with the letters “T” or “L”.
| Wire Color | Function |
|---|---|
| White/Green | Tip |
| Green | Ring |
Connect the Wires to the Jack
Once you have stripped the insulation off the telephone wires (refer to the previous section for instructions on how to do this), you need to connect them to the terminals on the telephone jack. The jack will have four terminals: two for the tip and two for the ring. Identify the tip and ring wires using the color code provided in the previous section.
| Wire color | Tip or ring |
|---|---|
| Solid brown | Tip |
| Solid green | Tip |
| Striped brown | Ring |
| Striped green | Ring |
Connect the tip wires to the tip terminals on the jack, and connect the ring wires to the ring terminals. It doesn’t matter which tip wire goes to which terminal, and the same is true for the ring wires.
Use a small screwdriver to tighten the screws on the terminals to secure the wires. Make sure that the wires are securely fastened and that no bare wire is exposed.
Once the wires are connected, you can plug the jack into the wall. If you have a landline phone, you should now be able to make and receive calls.
Mount the Jack in the Wall
1. Mark the stud location: Use a stud finder to locate the nearest stud (vertical support beam) in the wall where you want to mount the jack. Alternatively, you can tap on the wall with your knuckles. A solid sound indicates a stud.
2. Drill the mounting hole: Using a 1/2-inch drill bit, drill a hole through the wall at the marked stud location. The hole should be 1-1/2 inches deep.
3. Insert the jack box: Push the plastic jack box (included with the jack) into the hole in the wall. It should fit snugly and remain in place.
4. Secure the jack: Gently pull the telephone cord through the hole in the jack box. Strip about 1/2 inch of insulation from the ends of the wires.
5. Punch down the wires: Use a punch down tool to connect the stripped wires to the punch down blocks inside the jack. Follow the color-coded terminals (marked as “A” and “B”) to match the wires.
6. Tighten the faceplate: Screw the faceplate (the decorative cover) over the jack box to secure it. Use a screwdriver to tighten the screws until snug. Be careful not to overtighten, as it can damage the jack box or the wall.
| Terminal | Color | Wire |
|---|---|---|
| A | Red and Green | Positive |
| B | Yellow and Black | Negative |
