Definition 1. - 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 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 East Brimfield 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 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.

East Brimfield, Massachusetts, Aug. 28 /Brendan Luna/ -- 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.

To illustrate the types of decisions that small business owners are faced with on a daily basis, we interviewed Glenda Probst, small business owner in Los Angeles, California, about her recent move to a dynamic integrated T-1. "I was in a quandary about how to go about expanding the number of voice lines to my business. Before making the move to a dynamic integrated line, I was using POTs lines. After the fifth line, my bill was above $300/month, not including my $100/month DSL connection. Now, I have 12 pure digital voice lines, 1.5 MB of broadband, and I pay under $400 for it. It was a major upgrade in service with a reduction in total price. I only wish I'd learned about this product sooner."

"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."

The old-school integrated T-1 was analog in nature, and came with 24 configurable channels (called a trunk) which could be configured to carry either voice or data traffic. The new "dynamic" trunks are all-digital and can change on-the-fly to carry either data or voice traffic. This comes in handy when none of the voice lines are in use - all channels can revert to carrying data traffic, giving the end-use a full 1.5 MBPS of broadband. Each phone call requires only 64K of bandwidth, so even a small handful of calls only slows down the data connection by a nominal amount.

Integrated T1s comes in two basic configurations: digital and analog trunks, with a trunk being a 24-line (or channel) bundle. The newer, digital trunks, however, are able to run both voice and data over the same channels. By assigning priority to the voice traffic whenever it is present, a dynamic integrated trunk can provide the end-user with a full 1.5 MBPS of data throughput if no phone calls are in progress. As more voice lines are required, less data lines are available. Analog trunks are all pre-assigned to either voice or data traffic, and do not reconfigure in the event there is no voice traffic.

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.

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. 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.
