There will be a line plugged into each modular plug for each phone company line that runs to your house. The pair of screw posts will contain one red screw and one green screw. These posts are where your new wiring will connect to the phone company wiring.
This line must be plugged back in once you’ve completed the wiring.
If you already have a telephone jack in your house, skip this step. If you have a telephone jack but no cable, follow the linked article’s steps to connect one end of a telephone cable to the telephone jack.
Clip the end of the phone cable off. Strip an inch off of the end of each of the colored wires. Separate the green wire and the red wire. Unscrew the red connector screw and the green connector screw (or both of the screws in the “Line 1” area). Wrap the red wire’s bare section around the red connector’s screw, then repeat with the green wire and the green connector. Re-tighten the screws.
You may have to call the company and request that they activate your phone line before you can use your landline.
Unless otherwise specified by your phone’s manufacturer, avoid using the “Line 2” or other ports on the back of the receiver.
Skip this step if your phone doesn’t have an “Internet” port.
Your phone receiver may have a built-in power cable. If so, just plug the free end of the cable into an electrical outlet.
