How to Add a Phone Line
A step-by-step guide to installing a second phone line for voice, fax, or e-mail
Imagine the convenience of having a second telephone line in your home. Not just an extension to your current phone, but another line with its own number. It could be used as the kids' phone or reserved for home business or Internet use. And all the while your original phone line will remain open for making and receiving calls.
Installing a new phone line is surprisingly easy and safe. Phone wires carry a very weak electrical charge and you'll only need a few basic tools to complete the job. But best of all, most of the wiring needed to connect a second phone line is already in your home. The telephone cable in your house right now contains at least four wires, but only two of them are connected to your current phone. Therefore, you can tap into the two unused wires to feed the new phone line.
