What is DSL Internet?
DSL internet is an internet connection delivered over copper wired telephone lines. The internet data can be delivered at the same time as phone service because it uses higher frequencies to deliver data. In some cases, a “naked DSL” is configured (also called “standalone” or “dry loop DSL”), which uses the line exclusively for data transfer without any traditional telephony service. Voice transfer can still be achieved in this case with a VoIP service. DSL continues to be the dominant technology for broadband connection, in part because of the prevalence of telephone infrastructure.
What Does DSL Stand For?
DSL stands for Digital Subscriber Line, though it used to be Digital Subscriber Loop. ADSL stands for Asymmetric Digital Subscriber Line. Most DSL lines are asymmetric lines, which means the speed or bit rate is not the same in both directions (upload / download). With any data connection the download speed is usually higher than upload speed by design since people download information more frequently than they upload. For users that need the download speed to be equal to the upload speed, they can use a Symmetric Digital Subscriber Line (SDSL).
