  Do I need a DSL Provider and an ISP?
Yes. To access the internet, both a DSL Provider and an Internet Service Provider (ISP) are needed. In some cases, the same company can provide both services.
  What role does a DSL provider play when connecting to the Internet?
A DSL Provider, such as CenturyLink, supplies the physical telephone line required to have access to the internet in your home or business. A high-speed Internet modem that is compatible with your DSL Provider's network is required. Some DSL Providers offer a selection of modems, while others may be obtained via your ISP.
  What role does an ISP play when connecting to the Internet?
An Internet Service Provider (ISP) supplies access to the internet over the DSL Provider's telephone lines. The ISP will also provide customer specific information, such as a username and password, that are required to connect to the internet. Some ISPs will also offer the high-speed Internet modem needed to connect your computer to the telephone phone jack. They may also offer additional services or applications such as e-mail, web hosting, Internet security software, etc. Check out the ISP List to see if your ISP supports CenturyLink Broadband.
