Yes. DSL technology uses the phone line, but not the voice component. This is why the divided line allows you to simultaneously surf the Internet and talk on the phone line at the same time. Because DSL technology divides the line, the two parts aren’t dependent upon one another, nor do they interfere with one another. Consequently, you can choose to pay for voice service, DSL service or both services on your phone lines. If you don’t have phone lines or phone lines that can be activated, you can’t get DSL service.
