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 Grindstone 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 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 4. - 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.

Grindstone, New York, Sep. 26 /Jason Young/ -- 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 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.

The two basic Integrated T1 line configurations, as they exist in today's market, are analog and digital. Commonly referred to as "trunks", these 24-channel bundles transmit TDM signals directly to the service provider's network via a local loop. Unlike analog trunks, whose configuration can not change once the channels have been allocated, digital "dynamic" lines can change reconfigure themselves from data, to voice, and back again. This ability to reclaim voice channels for data broadband access when not in use gives the user the performance of two T1's in one.

New York is a place that we found was a hot spot for small business owners making the move over to dynamic T-1 lines. One business owner that we interviewed gave glowing reviews of his move to TelePacific's "OnePac" dynamic product. Keith Gray explained "I used to have a regular integrated T1 with 10 voice lines and 14 data channels. When no one was using the phone in my office, we were limited to just 896 KB of bandwidth. After searching on the Internet for better options, I found that I could reduce my price from $850/month to $500/month, and at the same time have 14 voice lines and 1.5 mbps of broadband. I didn't take long for me to pull the trigger and make the change."

To see how customers are reacting to this new product, we interviewed a series of small business owners in New York who are currently using the service. One such individual shared with us his enthusiasm for the enhanced capabilities dynamic service offers. "When I was first contacted about the dynamic integrated T1, I was deeply skeptical of what I was hearing. Over the course of my brief dealings with telephone companies, all I got was less service with more cost. Now I am happy to say that I am getting more for less, which makes for one very happy customer."

"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."

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. The golden age of telecommunications may be upon us, based upon our research and recent uptick in customer satisfaction. Although the industry has years of bad blood to overcome, recent innovations such as the dynamically configuring T1 line are proof that progress is indeed being made.
