DSL Internet (Digital Subscriber Line) is a broadband technology that transmits high-speed digital data over existing copper telephone lines. It enables users to have internet access and telephone service simultaneously on the same line without interference. DSL works by dividing the frequency range of the telephone line into separate channels for voice and data, allowing data to be sent as digital signals at higher frequencies than those used for telephone conversations. Key points about DSL Internet:
- Uses existing telephone lines (copper wires).
- Provides always-on internet access with speeds typically ranging from several hundred kilobits per second to tens of megabits per second.
- Allows simultaneous use of telephone and internet.
- Different types include ADSL (asymmetric, faster download speeds), SDSL (symmetric upload and download speeds), and VDSL (faster speeds over shorter distances).
- DSL modems convert digital data from devices to signals transmitted over phone lines and vice versa.
DSL is widely available, relatively affordable, and suitable for various internet activities from browsing to streaming, depending on the specific DSL type and plan.
