DSL service for business from Covad

DSL Basics

DSL (digital subscriber line) Service is a proven technology that uses standard telephone lines to provide reliable, high-speed Internet access. DSL is "always-on," providing high-speed Internet connectivity for websites, email, and other online applications. Unlike other broadband technologies, DSL service offers higher average speeds and fewer bottlenecks to slow you down.

Different Types of DSL

Covad offers a range of different DSL technology types that offer unique upload or "send" and download or "receive" characteristics. Below is a quick overview of the different types of DSL.

  • ADSL—Asymmetric DSL splits resources to give you higher download speeds than upload speeds. If you spend the majority of your time viewing websites and checking email, and less time sending files or running network applications, ADSL is your best choice.
  • IDSL—ISDN DSL is a symmetrical technology providing equal upload and download speeds. Generally, it is recommended for users unable to obtain other DSL services at their location.
  • SDSL—Symmetrical DSL also offers equal download and upload speeds. It is ideally suited for users working with large files, network applications, or maintaining in-house email or Web servers.

DSL is not the only broadband technology that Covad has to offer. For businesses that demand maximum speeds, enhanced features, and aggressive service level agreements, Covad T1 is an industry-leading choice.
