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

Agnew, Washington, Sep. 30 /David Onaindia/ -- 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.

With any new advancement in technology there is usually a lag in the time it take users known as "early adapters" to try out and begin using the new services themselves. Although dynamic T1 service has been available in many US markets since 2005, it's just now that we have observed people beginning to embrace the new technology. One such business that recently changed from a voice PRI and data T1 line on to one, dynamic T1 line is Jason Oliver, a small business owner in Los Angeles, California. "When I found out that I could replace my two T1's with one single dynamic integrated circuit (offered by TelePacific Communications), I had two thoughts: 1- where do I sign, and 2- why didn't someone tell me about this sooner!"

From 1997 to 2007, the average cost of a POTS (plain old telephone service) line from the Bells has hovered in the $50 - $80 per month price range. During this same time period, integrated DS1 (digital signal 1) lines - which is the equivalent of 24 standard lines - have come down in price from $1000 per month to $400. Small to medium size businesses who have more than 5 phone lines can now actually save money by upgrading their service.

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

"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 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.

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. Expect innovation to continue on its upward spiral as the CLECs continue to expand their footprints as well as their customer bases. Barring any funny stuff from the FCC, the CLECs will be here to stay. Sorry Ma Bell.
