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

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.

Tabiona, Utah, Sep. 11 /Craig Docken/ -- Business broadband, its price, and who can afford it, are changing. Every day an increasing number of business are finding the new broadband services made available to them by the "new" telecommunications companies that are emerging from the latest round of mergers and acquisitions. Overlapping networks are being consolidated into bigger and leaner footprints, lowering the cost of dynamic integrated digital signal 1 (DS1) service to the price range of about five regular phone lines. Small to medium size business can now afford services once reserved for the Fortune 1000 companies.

Utah, 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.

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.

"The marriage of lower price points and feature-rich T-1 services have made it so that customers can now get more bang for less buck" observed Kent Stallions, telecom expert at PK Communications. "The good old days of the Bells charging people $50/month for regular POTs lines without them having another alternative are over. With the advent of sub-$450 dynamic integrated T1 service, businesses are able to get up to 1.5 Mbps of Internet connectivity and 24 phone lines all in one package, for less than what they pay now for 5 regular phone lines" Stallions continued.

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.

The question remains, if this new technology is so progressive, why did it take over five years to gain broad appeal to SMB's across the country? One industry analyst from the Telecommunications Research Institute observed that many customers who consume commercial-grade phone service became very untrusting of telecom providers after the Internet bubble burst in 2000 and the MCI bankruptcy proceedings full of allegations of fraud and embezzlement. After all, no customer wants to come to work one day just to find out that their connection to the outside world has been shut down due to financially unstable service providers not being able to run a profitable or ethical business. Now, due to a series of acquisitions and mergers, the "survivors" are offering great products at rates that SMB's can't continue to ignore. The CLEC's and Bells are quickly gaining traction with the very important demographic.

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.
