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 Allstate Insurance Co T1 line is in common use today in ISP (Internet Service Provider) connections to the Internet

Definition 2. - 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.

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. - 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.

Is it time to upgrade to a T1? There are several factors to consider when examining you current DSL connection and the possiblity of replacing it. For many people the biggest factor is reliability and if reliability is critical to the applications you run over your connection you should seriously consider replacing your DSL connection with a T1. DSL is a quick and cost effective method of acquiring high speed bandwidth however it is not intended to support commercial applications or large numbers of users as is a T1 connections.

Reliability becomes critical when customers or employees depend on your connection for immediate responses. If your customers use your connection to access your databases or your server or the internet then reliability of your connection is critical. If your employees depend on your connections because you host the e-mail server in house or host web servers, your connections is considered critical. A critical connection can be viewed much like a life line, without which your business would be negatively impacted. Your monthly savings of having a sub-par connections will not make up for the loss in productivity of your employees or loss of customers when your DSL connections gets bogged down or cut off. To reiterate, ciritcal connections should be supported with a T1.

Many customers are extremely price sensitive and cannot afford the cost of a T1 which can be as much as 20 times more expensive than a full T1 connection. Residential customers who are most sensitive to price should not consider a T1 circuit unless then have a business reason to pay for such a circuit and cannot access DSL service. Most people don't realize that a DSL connection can be just as fast as a T1 at 1.5Mbps. The shortcoming of DSL is that it is oversubscribed. This means there is a finite amount of bandwidth available and a customers speed can drop if other customers in the neighborhood decide to use their service. SDSL (Synchronous DSL) is a business class DSL and is ranked as a higher priority than residential DSL or ADSL (Asunchronous DSL). This means it is not oversubscribed to the extent than ADSL and is subject to fewer bandwidth restrictions. In short, if price is your critical factor go with DSL. If reliability is the critical factor purchase a dedicated T1.
