Definition 1. - 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 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. - 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 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.

Louisiana, Jun. 11 /Olamide Lieberman/ -- Is there a resurgence in the popularity of telecommunications providers that compares with the late 1990's? The answer may surprise you. Since the crash of the Internet bubble, struggling telecoms have seen Darwin in action as many companies were forced with the choice of bankruptcy or forced consolidation. However, some companies chose the road less traveled: innovation. By offering customers more for less, many small to medium size business customers are finding that they can upgrade to integrated T1 service for the same cost of five regular phone lines.

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.

At $50 to $75 per month, the average small business telephone customer could expect to pay up to $750 for just 10 regular phone lines, which come with only a standard set of features such as Voicemail, Caller ID, and Three-way calling. From 2000 to 2005, the cost of a dynamic integrated T1 line was well over $800, making it an unattractive option from a pure cost point of view. However, that paradigm has changed with the introduction of sub-$400/month price plans and features that make the old POTs lines look pre-historic.

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.

Min Lieu owns a small insurance agency in Louisiana. 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."

Is the era of the analog trunk, or bundle of 24 DS-0 (64 kbps) channels, officially over? Possibly, thanks to the two-for-the-price-of-one features of a dynamic integrated T1, which can function exactly like a pure 1.5 mbps data T1 when no one is one the phone, and allocate required bandwidth for voice traffic when a user initiates a phone call. Likewise, as soon as the client terminates the voice session, the 64 KB is re-assigned back to the digital universe. This switch-hitting capability provides all of the feel and function of a data T1 and voice T1, for a fraction of the price.

But how much longer will we continue to see improved technology, services, and prices? It's all in the hands of the Federal Communications Commission, as they have the power to sqwash the CLECs by proxy. No wonder AT&T and Verizon are the two biggest lobbying powers in Washington. It makes you wonder what kind of services they would be able to offer had they plowed that money into R&D instead of politics. With the help of super-CLECs like XO Communications, PAETEC, Nuvox, One Communications, Cavalier Telephone, and TelePacific, small business owners everywhere now have access to non-Bell service that is on par or better than those being offered by the former Bells. Integrated T1s that do more and cost less have transformed into a solid beach head for the newcomers.
