Definition 1. - 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 2. - 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 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 San Jose T1 line is in common use today in ISP (Internet Service Provider) connections to the Internet

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.

San Jose, Texas, Apr. 17 /Brendan Luna/ -- The way business connect to the digital universe is changing. More and more enterprises are discovering the new broadband options made available to them through a series of cost cutting measures by telecommunication providers. With the recent rush to consolidate, more and more features are being crammed into the current service offerings, which continue to fall in price bringing products like integrated T1 service into the price range of the vast majority of small to medium-size businesses.

The irony of the new small business communications revolution is that it took so long to gain traction. The whole idea of reclaiming inactive voice channels for data applications is not new, and was introduced by many CLEC operators over five years ago. So why did it take so long for SMB's to adopt the technology and make the change? One might argue that the Internet bubble burst in 2000 shook many people's confidence in telecommunications, one of the hardest hit industries. With so many telecoms going out of business, or merging with other small players just to stay solvent, many customers took the "wait and see" approach before making the decision to entrust their communications with a company not associated with Ma Bell. Now that economic Darwinism has taken hold, the remaining companies are attracting new customers who see the benefits of the new technology without the downside risk of loosing service or not being able to get through to customer service in the pinch.

There are two basic "integrated" DS-1 configurations, analog and digital. The 24-line bundle in which they come is termed a "trunk". The main difference between analog and digital trunks is their flexibility. With digital trunks, voice lines not in use can be dynamically reconfigured to carry data traffic, so they don't sit idle. Analog trunks on the other hand can not change their function once configured by the service provider. Data channels remain data channels and the same for voice channels, even if there is no voice traffic.

Min Lieu owns a small insurance agency in Texas. Five years ago he signed up with XO Communications for a TDM-based integrated T1 line for $870/month, which did not include local or long distance calling. Recently, he was offered XO's version of a dynamic circuit called "XO Flex" for half of the price he was already paying. "I would have been a fool not to take the deal" stated Mr. Lieu. "I'm able to add headcount with additional voice lines, without any increase in expense or degradation in high-speed Internet performance."

The only thing that can get in the way of future progress is the law. You know, the one that requires the RBOCs to lease their local loops to CLECs at a reduced rate so that the customer can get a dedicated connection between their office and the CLECs' network. If the FCC decided to lift this requirement, this whole deck of cards could come down in a hurry, and when it does, you can kiss dynamic integrated T1 service for under $500 good bye!
