DSL service in Colorado is available in most areas that are within a specified distance from a provider's equipment. DSL is much faster than dial-up, with download speeds ranging from 256K per second to 24MB per second depending on the type of technology and distance from the provider's central office.

DSL, short for Digital Subscriber Loop or Line, is a high-speed Internet connection over telephone lines. It uses a higher frequency than voice transmission so you can use your phone and access the Internet at the same time.

DSL is set up by installing a DSL modem or router that connects to a phone jack. To prevent feedback and noise, a filter is placed on the phone line to block out the high frequencies used for data transmission.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Keep in mind that Colorado DSL providers who don't own the phone lines have limited control over system outages and service levels. Independent providers of DSL Internet service may provide more competitive pricing and better business packages than the major telecoms. However, it can take longer to resolve service issues.
• •  Find out whether the provider offers a free router with its service. DSL can be routed across your network, but speed will be reduced as more people use the connection. Many DSL routers include firewall and routing services. Consider upgrading your router if it doesn't meet your needs.
