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

Definition 3. - 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 4. - 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.

Sanders, Kentucky, Oct. 28 /Hunter Sheffield/ -- 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.

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

The early adapters of this new technology have realized a cost savings that helps them be more competitive in the market space. By saving hundreds of dollars each month, which equates to thousands of dollars per year, small businesses are able to do more while spending less on their telecom bill. This savings allows for hiring of additional staff, upgrading equipment, and other activities that make the enterprise more productive and profitable. Many in the industry see the lack of mass adoption of this new technology as just shear ignorance and/or a lack of trust for telecom sales people.

At $50 to $75 per month, the average small business telephone customer could expect to pay up to $750 for just 10 regular phone lines, which come with only a standard set of features such as Voicemail, Caller ID, and Three-way calling. From 2000 to 2005, the cost of a dynamic integrated T1 line was well over $800, making it an unattractive option from a pure cost point of view. However, that paradigm has changed with the introduction of sub-$400/month price plans and features that make the old POTs lines look pre-historic.

"The real benefit I've seen since upgrading to a dynamic integrated T1 from Nuvox Communications is simplicity" commented Johan Sebastian, a small business owner in Clearwater, Florida. "My phones work great, my internet is fast, and the best part is the reliability; I haven't had a single outage since I signed up for the new service over a year ago. Before when we had DSL and POTS lines, every day was an adventure."

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.

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.
