DSL Full Form – What Is The Full Form Of DSL

DSL Stands for Digital Subscriber Line. It is a technology in which digital data transfer is done by Telephone Line. Telephone Line is a copper wire, through which the signals are transmitted. Voice signals are transmitted at low frequency (from OHz to 4KHz) and digital signals are transmitted at higher frequency (from 25KHz to 1.5MHz).

Types of DSL 

Symmetric DSL (SDSL) – It provides Same Bandwidth to both Downloading and Uploading. This Can provide up to 5 Mbps speed.

Asymmetric DSL (ADSL) – In this, downloading is more than uploading. It includes downloading speeds up to 7 Mbps and Uploading Speed ​​comes up to 1.5 Mbps.

Hight Bit-Rate DSL (HDSL) – This is also a Symmetric Connection i.e. it has the same downloading and uploading speed. It happens in big corporate company. Its range is up to 12, 000 – 15, 000 feet.

Rate – Adaptive DSL (RADSL) – It works both in a Symmetrical and Asymmetrical manner. In this, we can also make changes in Data Transfer Speed, Bandwidth etc.

Very High Bit-rate DSL (VDSL) – This is the fastest Data Transmmition Technology ever, with Downloading Speed ​​13 – 52 Mbps and Uploading Speed ​​ Up to 1. 5 – 2.3 Mbps.

Advantages of DSL

  1. You can use both Internet and Phone Line at the same time.
  2. DSL Speed ​​is faster than all other Modem.
  3. New Wiring is not required for this, only the existing Telephone Line is used.
  4. It is cheaper than Cable Connection.
  5. You can also get different Connection Speed ​​according to different pricing.
