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. - 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 Worthington 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. - 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.

Worthington, Iowa, Sep. 11 /Chris McMillen/ -- Small businesses all over the country are discovering a whole new universe of broadband access. As the price of commercial-grade telecommunication services continues to drop, more and more enterprises are starting to drop their plain old telephone service lines in favor of all-digital T1 trunks that deliver voice and data over the same connection. These new enhancements were made possible by the increasing pace of consolidation in the telecommunication industry along with the increasing value bigger phone companies can provide.

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.

The irony of the new small business communications revolution is that it took so long to gain traction. The whole idea of reclaiming inactive voice channels for data applications is not new, and was introduced by many CLEC operators over five years ago. So why did it take so long for SMB's to adopt the technology and make the change? One might argue that the Internet bubble burst in 2000 shook many people's confidence in telecommunications, one of the hardest hit industries. With so many telecoms going out of business, or merging with other small players just to stay solvent, many customers took the "wait and see" approach before making the decision to entrust their communications with a company not associated with Ma Bell. Now that economic Darwinism has taken hold, the remaining companies are attracting new customers who see the benefits of the new technology without the downside risk of loosing service or not being able to get through to customer service in the pinch.

Is the era of the analog trunk, or bundle of 24 DS-0 (64 kbps) channels, officially over? Possibly, thanks to the two-for-the-price-of-one features of a dynamic integrated T1, which can function exactly like a pure 1.5 mbps data T1 when no one is one the phone, and allocate required bandwidth for voice traffic when a user initiates a phone call. Likewise, as soon as the client terminates the voice session, the 64 KB is re-assigned back to the digital universe. This switch-hitting capability provides all of the feel and function of a data T1 and voice T1, for a fraction of the price.

When asked about his recent decision to replace his TDM channelized T1 with a SIP-enabled dynamic T1, Robert Probst, small business owner in San Diego, explained that "it was really an easy decision to make. My business was growing and I couldn't afford the cost of more voice trunks. When I learned that it was possible to have up to 16 voice lines, and a full data T1 of high speed Internet bandwidth, all on the same line, for under $500 - I was sold. I ended up expanding the telecom capability of my business, improving the quality of my Internet connection, and saved money while doing it."

Adoption of new technologies take time, and dynamic integrated T1 service is no different. Since the telephone service is regarded more as a utility than anything, business pay very little attention to changes in the industry. Significant price reductions and incentive packages need to be placed on their doorstep by proactive consultants and telecom salespeople in order to grab their attention. However, once the new technology begins becoming commonplace in the industry, momentum builds and soon the new products become standard. Businesses soon see themselves at a disadvantage to their piers if they don't adapt and keep up.

Evolution has lead to a better, cheaper alternative to TDM services that the Bells were peddling for decades in a vacuum of competition. Now the industry, lead by the innovation and great business practices of the CLECs, seems to have turned a corner - leaving the incumbents playing catchup. Obviously, the main benefactor of all of this competition is the small to medium size business - a segment of the market that was taken for granted until today. The only thing that can get in the way of future progress is the law. You know, the one that requires the RBOCs to lease their local loops to CLECs at a reduced rate so that the customer can get a dedicated connection between their office and the CLECs' network. If the FCC decided to lift this requirement, this whole deck of cards could come down in a hurry, and when it does, you can kiss dynamic integrated T1 service for under $500 good bye!
