DSL - High Speed Internet



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.

DSL is a very high-speed connection that uses the same wires as a regular telephone line. Typically, the download speed of DSL ranges from 128 kilobits per second (kbit/s) to 24,000 kbit/s depending on DSL technology and service level implemented. Upload speed is lower than download speed for Asymmetric Digital Subscriber Line (ADSL) and equal to download speed for Symmetric Digital Subscriber Line (SDSL).

Here are some advantages of DSL:

  • You can leave your Internet connection open and still use the phone line for voice calls.
  • The speed is much higher than a regular modem
  • DSL doesn't necessarily require new wiring; it can use the phone line you already have.
  • The company that offers DSL will usually provide the modem as part of the installation.
But there are disadvantages:
  • A DSL connection works better when you are closer to the provider's central office.
  • The connection is faster for receiving data than it is for sending data over the Internet.
  • The service is not available everywhere.

Types of DSL include:
  • Asymmetrical DSL
  • Very high bit-rate DSL (VDSL)
  • Symmetric DSL (SDSL)
  • Rate-adaptive DSL (RADSL)
