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

Greenvale, New York, Sep. 03 /Jeff Johnson/ --
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.
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!"
"I am very satisfied with my new XO dynamic T1" added Mike McLoude, a small business
owner in Santa Monica, California. "The flexible nature of the system allows me to
conduct business with the same efficiency as many of my bigger competitors, for less
than what they pay." Mr. McLoude is not alone - many Californians are seeing the
technology light and taking the leap of faith away from traditional TDM.
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.
From 1997 to 2007, the average cost of a POTS (plain old telephone service) line from the
Bells has hovered in the $50 - $80 per month price range. During this same time period,
integrated DS1 (digital signal 1) lines - which is the equivalent of 24 standard lines -
have come down in price from $1000 per month to $400. Small to medium size businesses
who have more than 5 phone lines can now actually save money by upgrading their service.
"I think the telecom industry in general has turned a corner" opined Jerry Gold of
Boston, Massachusetts. "They have finally developed products that are understandable
by the industry outsider and, thanks to competition, priced these services in a
range that most small businesses can afford. For over 20 years I dreaded dealing
with 'the phone company'. But now that I've switched over to One Communications,
my integrated T1 is doing everything I need it to, for under $450/month. One
actually answers their customer service calls and makes me feel like I'm part
of their family. It was a long time coming, but I'm finally able to end the
fight with the phone company so I can focus on my sports memorabilia store."
Hopefully the CLECs can continue to push the boundaries of innovation and economics.
The only thing that can keep them from the promise land is the gatekeeper of competition:
the Federal Communications Commission, and the huge Bells (AT&T and Verizon - that's you)
who make it a point to spend more money lobbying in Washington DC than Exxon Mobile. Until deregulation allowed smaller, hungrier telecommunications companies the
ability to compete, the United States was stuck with technologies that were quickly
becoming out of date. Now that the Bells actually have to innovate to keep up with
the smaller CLECs, customer everywhere are reaping the benefits.
