Definition 1. - 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 2. - 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 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 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.

Tennessee, Oct. 24 /David Onaindia/ -- 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.

Given the fact that many companies still to this day have yet to make the change to digital SIP-trunking enabled dynamic T1s, one must ask why the delay? The value proposition that dynamic adds and the economic benefits are there, however, the technology is slow to be adopted by mainstream corporations. One reason for this lag is the bad reputation that telecom companies have built for themselves through the meltdown of the industry from 2000 to 2003, when many companies either went out of business, merged with other larger companies, or just hunkered down and weathered the storm. Now that the industry has made great strides to stabilize by offering better rates, better products, and better customer service, small business owners are gradually starting to listen to the presentations being made by consultants and inside sales agents. With that increase in confidence, and with the growing number of testimonials being offered by happy customers, businesses are becoming less reluctant to make the jump.

"Even though we have been witnessing the re-consolidation of AT&T, we will never go back to the dark ages of telecom where customers were stuck with bad customer service and high prices" commented Troy Karlson, telecom analyst for e-STAR. "The competitive local exchange carriers (CLECs), all whom own their own networks and compete directly with the Bells, have created products such as dynamic T1 service that enables its customers to connect to the Internet at 1.5 MBPS and have up to 24 regular voice lines, packed with a feature-rich suite of add-ons, all for under what it costs to have 6 regular phone lines from Qwest/AT&T/Verizon.

Tennessee, ordinarily not known for its telecom prowace, has been a hotbed for businesses making the move to dynamic telecom lines. One local business owner - Linda Peterson - who operates a travel agency, recently told us that "I never expected the phone company to come out with anything that would help me lower my costs. On the contrary. Ma Bell has had a history of raising my rates and making my life difficult. When I heard about the XO Flex package (offering 10 dynamic voice lines and 1.5 mbps of high speed Internet) at a price of under $500, I couldn't move over fast enough." Since then Linda reported a $150/month savings in her telecom expenses.

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.

One might think that, given the cost - benefit analysis of the integrated T1 value proposition, more businesses would be changing over to the new platform. However, the rate of adaptation is rather slow. Rob Butler, head of the Telecommunications Research Institute, thinks that "phone companies have a problem with trust amongst their user base. For many years, customers have dealt with increasing rates, long hold times, and frustration in general. Now, it appears, the ice is finally starting to melt and customers are opening themselves up to new technology.

Looking in the crystal ball of the future, it is clear that new an innovated services being offered by the few super-CLECs remaining will drive innovation higher and prices lower. New technology is being pressed to the forefront by lower prices that the mainstream of small businesses everywhere can comfortably afford. 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.
