Definition 1. - 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 T1 line is in common use today in ISP (Internet Service Provider) connections to the Internet

Definition 2. - A high-speed digital connection capable of transmitting data at a rate of approximately 1.5 million bits per second. A T1 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 T1 is basically too large and too expensive for individual home use.

Definition 3. - A type of high speed Internet connection that provides a great deal of bandwidth. Many businesses lease T1 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 4. - The T1 (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). T1 lines use copper wire and span distances within and between major metropolitan areas. A T1 Outstate System has been developed for longer distances between cities.

Nebraska, Feb. 04 /David Onaindia/ -- The same basic economic model described in the book "Blue Ocean Strategies" is now being applied to telecommunication services being offered to small businesses across the country: more value for less money. According to many industry watch dogs, hundreds of thousands of business will dump their POTs lines in favor of dynamic integrated T1 service within the next 12 to 24 months, saving money in the process. With the introduction of sub-$475 dynamic integrated T-service, customers are now able to receive up to 1.5 MBPS of high-speed Internet with 24 digital phone lines all on one line, for less than what they pay now for 5 regular phone lines" Stallions continued.

"The marriage of lower price points and feature-rich T-1 services have made it so that customers can now get more bang for less buck" observed Kent Stallions, telecom expert at PK Communications. "The good old days of the Bells charging people $50/month for regular POTs lines without them having another alternative are over. With the advent of sub-$450 dynamic integrated T1 service, businesses are able to get up to 1.5 Mbps of Internet connectivity and 24 phone lines all in one package, for less than what they pay now for 5 regular phone lines" Stallions continued.
