Written by: ShopForT1.net - Nov 20, 2008

Definition 1. - A type of high speed Internet connection that provides a great deal of bandwidth. Many businesses lease DS1 lines to connect to the Internet, but because they are expensive and offer more bandwidth than most small businesses and homes need, they are not realistic solutions for small and low-demand Internet users.

Definition 2. - The DS1 (or T-1) carrier is the most commonly used digital line in the United States, Canada, and Japan. In these countries, it carries 24 pulse code modulation (PCM) signals using time-division multiplexing (TDM) at an overall rate of 1.544 million bits per second (Mbps). DS1 lines use copper wire and span distances within and between major metropolitan areas. A DS1 Outstate System has been developed for longer distances between cities.

Definition 3. - The T-carrier system, introduced by the Bell system in the US in the 1960's, was the first successful system that supported digitalised voice transmission. The original transmission rate (1.544 Mbps) in the DS1 line is in common use today in ISP (Internet Service Provider) connections to the Internet

Definition 4. - Digital Service rate 1. The combined transmission rate (1.544 Mbps) of all 24 circuits in a DS1 connections. A DS1 line is typically used by small and medium-sized companies with heavy network traffic. It is large enough to send and receive very large text files, graphics, sounds, and databases instantaneously, and is the fastest speed commonly used to connect networks to the Internet. Sometimes referred to as a leased line, a DS1 is basically too large and too expensive for individual home use.
