High-Speed DSL (HDSL) Key Terms

Learn the language to understand your DSL options

High-speed DSL allows users to quickly access information on the Internet. The speed of an Internet connection refers to how quickly a user can download Web pages or other downloadable files. In the past, many people used a 56k modem, which could download 56,000 bits per second. These days, more people are turning to high-speed Internet connections in order to do business more effectively. Understanding DSL key terms will allow you to make smarter choices.

Digital subscriber line (DSL)

A digital subscriber line, more commonly called "DSL," is the technology that allows both homes and businesses access to the Internet. Users receive data over copper wires, similar to a phone line, but without requiring conversion from digital to analog format.

Asymmetric/Symmetric DSL

Asymmetric DSL (ADSL) and symmetric DSL (SDSL) are the two main types of DSL. With an asymmetric DSL connection, users are able to download data more quickly than they can upload it. With a symmetric DSL connection, upload and download rates are the same. Asymmetric DSL is much more common.

Business DSL

Most businesses require high-speed Internet connections. A T1 line is the fastest option, but is prohibitively expensive for many small business owners. Business DSL packages are less expensive, making them an attractive option. High-speed Internet companies offer special DSL packages for business owners, which may include more bandwidth and networking capabilities.

ISP

ISP stands for Internet Service Provider. A business or homeowner purchases his or her Internet connection through an ISP.

Ethernet cable

The Ethernet cable is the cable that connects your computer to the DSL modem. It is the means by which you can receive and send data over the Internet. You can also use Ethernet cables to connect your computer to certain types of printers.

Router

A router allows several computers to connect to the Internet through one DSL modem. This makes it easy for you to network the computers in your office.
