Overview DSL, or
Digital Subscriber Line, is a high-bandwidth Internet connection that uses
existing phone lines. It’s a fast changing technology, and DSL providers
frequently come and go. DSL Internet access continues to expand, partially
due to the partnerships being formed between DSL providers and large
telecommunications companies. Many Web sites provide information about DSL,
making it relatively easy to understand DSL technology and how it works.
Connection speeds for DSL typically range from 1.544 Mbps to 512 Kbps
downstream and approximately 128 Kbps upstream. These high transfer rates
are a result of using the full broadband spectrum available on standard
telephone lines, whereas standard modem and voice data uses only a portion
of the transfer capacity. The biggest drawback to DSL is that the user
must be in close proximity to a central telephone hub, or else the DSL
data signal deteriorates and becomes unusable. Visit the CNET
glossary page for a thorough explanation of DSL. For more details
about DSL technology, visit HowStuffWorks.com.
