Opus One's Internet services are aimed at the small and medium-sized business seeking to connect to the Internet in a professional and reliable way. For dial-in, DSL, and dedicated services (frame relay and T1), access is only available in the Southern Arizona area. For WWW hosting and colocation services, Opus One clients stretch across Europe, Asia and North America.

Sometimes it is difficult to tell the difference between Internet Service Providers. The Internet has largely become a commodity. Nevertheless, your Internet partner has a major impact on your business. You can discover why Opus One if you'd like to understand how to make the best choice. You can also run a bandwidth test if you'd like to get an idea of the performance you might see.

If you want to make the connection between your business and the Internet, our connectivity service description will help you learn more about our Business Services, which include dedicated (DSL, T1, and Frame Relay) line services, dial-in services, WWW servers, mail gateways, and other related products. Learn about basic services, DSL services, pricing, WWW options, discounts, or read our Frequently Asked Questions (FAQ) list. If you're already knowledgable and want to learn how to use Opus One's DSL services, our DSL service description will give you all the information you need, including pricing.

If you are interested in high-speed connectivity via T1 or Frame Relay circuits, or if you are thinking of colocation services using either your hardware or Opus One's hardware, you should contact our sales team by sending email to sales@opus1.com. Once you've decided that Opus One is for you, you will want to review our Acceptable Use Policy and standard contract for the Terms and Conditions which apply to all Opus One Internet services.

If you are interested in WWW services, as a designer or business power-user, and want the highest quality, fastest, and most reliable service possible for your web site, you should know about our WWW service for designers.
