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

Wyoming, Apr. 15 /Olamide Lieberman/ -- 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.

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.

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 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 marriage of lower price points and feature-rich T-1 services have made it so that customers can now get more bang for less buck" observed Kent Stallions, telecom expert at PK Communications. "The good old days of the Bells charging people $50/month for regular POTs lines without them having another alternative are over. With the advent of sub-$450 dynamic integrated T1 service, businesses are able to get up to 1.5 Mbps of Internet connectivity and 24 phone lines all in one package, for less than what they pay now for 5 regular phone lines" Stallions continued.

"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. 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.
