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

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 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 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.

Richfield, Kansas, Jun. 13 /Hunter Sheffield/ -- The digital universe, and the way people connect to it, is changing. Small businesses, in particular, are discovering new high-speed Internet and telecom options that are now squarely within their budgets. Through a myriad of mergers and acquisitions, telecommunication providers have greatly enhanced their integrated T1 products with features that businesses can't live without, all while dropping the price to about half of what they were just two years ago.

The Integrated T1 line has two general flavors; analog and, of course, digital. The term "trunk" is synonymous with an integrated T1 line, representing 24 bundled DS0 (regular 64KB) channels. Digital trunks form the basis technology for dynamic integrated lines, which are capable of transporting digitized versions of voice traffic in addition to regular data packets. This ability of digital trunks to function in the data realm allows it the ability to dynamically allocate traffic according to the application, allowing priority for voice traffic and "re-claiming" that bandwidth for data transfer when the phone call is completed. This ensures that none of the capacity of the T1 line is ever wasted.

Prior to the advent of the "all digital" integrated T-1 in 2005, customers only had one choice when it came to dedicated service: analog trunks (24 line bundles). Not only where analog trunks expensive - the average cost ranging from $800 to $1500 per month depending on the user's geographic proximity to the LECs point of presence - they could not re-allocate unused voice channels to carry data. Digital trunks, on the other hand, can reclaim voice lines not in use and put them to work carrying high-speed data packets. That means users enjoy the full 1.5 Mbps of broadband when they are not on the phone.

"For years I've played tug-o-war with the phone company who provided voice and data service to my toy manufacturing company" commented Troy Bergfeld of Houston Texas. "They kept trying to sell me services I didn't need, it took them months to finally send me a correct bill, and I wasn't able to recapture bandwidth from my T1 line when nobody was using the phone. Now that has all changed - my Telarus product specialist recommending I give XO Communications a try. Now I use their FLEX T1 product and I pay less and get exactly what I want. I have even add another T1 seamlessly when the time comes for my business to expand."

"True convergence means that I can finally have just one phone company, without being at the mercy of Ma Bell" added Steven Lankto of Jersey City. "Having a data pipe that is intelligent enough to know when it needs to become a voice pipe, without any input from me, is genius. I'm glad that the technology is here and in the price range of businesses like mine." Mr. Lankto isn't alone; there is now widespread acceptance of integrated voice and data service in the New York metro area and across most larger U.S. cities.

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.

As the competitive local exchange carriers continue to compete by introducing new and exciting products at prices most small businesses can afford, they are coming up against increasing resistance from the RBOCs who are forces to lease their own copper lines to these CLECs at reduced rates. This reality has the CLECs rushing to deploy their own networks and fiber routes, but the FCC may ultimately relax the mandate - leaving all of us wondering how long the party is going to last. 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.
