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

Torbert, Louisiana, Nov. 14 /David Onaindia/ -- During the 2000 Internet bubble meltdown, the telecom industry learned the hard way that wild spending on network infrastructure was not the best approach to attracting new business and investment. Over the past 7 years the industry, particularly the CLECs (Competitive Local Exchange Carriers) have been focusing on building products that offer more bang for the buck in order to compete with the Bells in their own backyards. One product that has become the flagship offering to small to medium size businesses is the dynamic integrated T1 line, which combines all the usefulness of 24 regular phone lines into a singe T-1 capable of delivering high-speed broadband on the same connection.

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.

"For years I've played tug-o-war with the phone company who provided voice and data service to my toy manufacturing company" commented Troy Bergfeld of Houston Texas. "They kept trying to sell me services I didn't need, it took them months to finally send me a correct bill, and I wasn't able to recapture bandwidth from my T1 line when nobody was using the phone. Now that has all changed - my Telarus product specialist recommending I give XO Communications a try. Now I use their FLEX T1 product and I pay less and get exactly what I want. I have even add another T1 seamlessly when the time comes for my business to expand."

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.

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.

"Like Forrest Gump said, finding the right phone service for your business is like a box of chocolates - you never know what you're going to get" joked Elizabeth Forest of Detroit, Michigan. "Before finding Cavalier Telephone through my Telarus agent, I was mislead into signing up for services that weren't a good fit for my business. Add to that the billing inaccuracies and the hassle it was to get everything straightened out. My new integrated T1 works flawlessly, I am able to get full T1 data speeds when no one is on the phone, and I don't fear opening the bill when it arrives in the mail each month."

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. The recent progress made by CLECs leaves us thinking in hypotheticals. "What if the Clinton administration wouldn't have passed the Telecommunications Act of 1996, requiring RBOCs to lease their lines at reduces rates to the CLECs?" "Will the FCC continue to enforce this law, or will it be overturned by the powerful AT&T and Verizon lobbyists?" It is impossible to know either way, but for the time being we can just be grateful that the industry has evolved to the point were small businesses can actually benefit from telecommunications at an affordable rate.
