About CenturyLink High-Speed Internet
CenturyLink High-Speed Internet gives you the ability to transmit high-speed data and voice traffic over the same telephone line. At speeds ranging from 256 Kilobits per second (Kbps) up to 40 Megabits per second (Mbps), you'll be able to use your telephone while you're connected to the Internet. Standard dial-up connections by comparison have speeds ranging from 14.4 Kbps to 56 Kbps.
There are technical limitations that may affect your ability to receive CenturyLink High-Speed Internet service on your chosen telephone line. We have a qualification process to test your individual telephone line for compatibility with CenturyLink High-Speed Internet service. Using customer records, we test your line for common characteristics known to interfere with CenturyLink service.
To check if you meet the qualifications for high-speed internet, check our high-speed internet availability tool. This tool will show you if the service is available in your area and what speeds you qualify for.
Upon receipt of your order, we perform additional physical tests on your line, ensuring you a reliable, high-quality high-speed internet connection.
Physical tests may reveal compatibility problems on your telephone line that were not identified by initial testing. In that case, you will be notified immediately that your line doesn't qualify for service, and the order will be cancelled. You will receive no charge for CenturyLink Choice DSL service or equipment.
