DSL service in Arizona 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.

There are plenty of Arizona DSL providers. To get an idea of which one is right for your business:

1. Compare the costs of Arizona DSL services.

2. Check out support options and service level agreements.

3. Look at other business services that are included in the DSL package.

Action Steps
The best contacts and resources to help you get it done

Browse directories of DSL Internet service in Arizona

To start your DSL search, find out if your local phone company provides DSL. Arizona is home to many phone companies that provide DSL. Browse directories of independent providers of DSL in Arizona to compare prices and services.

I recommend: The Arizona Corporation Commission shows local phone service providers on a state map. You can find independent DSL providers by municipality on the ISP Guide. Compare monthly rates to your local provider.

Check out national providers of DSL services in Arizona

A large national provider of DSL can offer excellent customer service and trouble-free connections. Some offer additional services, such as web hosting and email addresses, as part of the package.

I recommend: AT&T is one of the nation's largest providers of telecommunications and DSL services. Covad is an independent telecom that offers telephone lines as well as DSL and other Internet services. Qwest is a DSL provider in Arizona and also provides phone service there.

Look at smaller DSL service providers in Arizona

A smaller local ISP can offer lower costs and a more personal touch than the larger telecoms. You may be able to bundle services together to get a good deal.

I recommend: AngelFireAZ is a local ISP that provides service to northern Arizona. Convergent Broadband Communications (CBC) is a full-service provider of DSL. Packages include static IP addresses and email accounts.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Keep in mind that many independent AZ DSL providers do not own the phone lines and have limited control over system outages and service levels. While they may provide more competitive pricing and better business packages than the major telecoms, 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.
