Definition 1. - 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 Palmer T1 line is in common use today in ISP (Internet Service Provider) connections to the Internet

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 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.

Palmer, New York, Aug. 20 /Don Romburgh/ -- The digital universe, and the way people connect to it, is changing. Small businesses, in particular, are discovering new high-speed Internet and telecom options that are now squarely within their budgets. Through a myriad of mergers and acquisitions, telecommunication providers have greatly enhanced their integrated T1 products with features that businesses can't live without, all while dropping the price to about half of what they were just two years ago.

"When we moved into our new location here in Los Angeles" commented John Baker, a small business owner in San Diego, California, "we feared having to sign up for commercial telephone and internet service. Until about a year ago, the services being offered to us were TDM, which doesn't come cheap. Thankfully our Telarus commercial telecom broker recommended that we give TelePacific a try, and we did. One year later, we've never had an erroneous bill, our phone and data are all on one single dynamic T1, and we can focus on what we do best - brokering mortgages."

With any new advancement in technology there is usually a lag in the time it take users known as "early adapters" to try out and begin using the new services themselves. Although dynamic T1 service has been available in many US markets since 2005, it's just now that we have observed people beginning to embrace the new technology. One such business that recently changed from a voice PRI and data T1 line on to one, dynamic T1 line is Jason Oliver, a small business owner in Los Angeles, California. "When I found out that I could replace my two T1's with one single dynamic integrated circuit (offered by TelePacific Communications), I had two thoughts: 1- where do I sign, and 2- why didn't someone tell me about this sooner!"

"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.

"Commercial telecommunication providers were never on my Christmas card list" commented Jake Chang, a small business owner in Denver, Colorado. "Dealing with them meant erroneous bills, long wait times when trying to reach customer service, and taxes I could never understand. Now that we migrated to a dynamic integrated T1, my phone lines and high speed internet are bundled into one line with super reliability. Not to mention the fact that XO Communications, a CLEC, treats me like they actually want my business - not like I'm a pain in the you-know-what."

There are two basic "integrated" DS-1 configurations, analog and digital. The 24-line bundle in which they come is termed a "trunk". The main difference between analog and digital trunks is their flexibility. With digital trunks, voice lines not in use can be dynamically reconfigured to carry data traffic, so they don't sit idle. Analog trunks on the other hand can not change their function once configured by the service provider. Data channels remain data channels and the same for voice channels, even if there is no voice traffic.

Change does not happen quickly in an industry as so heavily regulated as Telecommunications. Recent industry consolidation has provided huge alternatives to the incumbents, who are now under pressure to keep up with new technologies while charging better prices to retain and attract new customer bases. 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!
