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

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.
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!"
Prior to the advent of the "all digital" integrated T-1 in 2005, customers only had
one choice when it came to dedicated service: analog trunks (24 line bundles).
Not only where analog trunks expensive - the average cost ranging from $800 to
$1500 per month depending on the user's geographic proximity to the LECs point
of presence - they could not re-allocate unused voice channels to carry data.
Digital trunks, on the other hand, can reclaim voice lines not in use and put
them to work carrying high-speed data packets. That means users enjoy the full
1.5 Mbps of broadband when they are not on the phone.
"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."
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.
"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."
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.
