Definition 1. -
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 2. -
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 3. -
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 Bethany T1 line is in common use today in ISP (Internet Service Provider) connections to the Internet
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.

Bethany, Oklahoma, Jun. 17 /Olamide Lieberman/ --
For many small to medium size businesses, higher productivity with relation to their broadband
and voice services is just around the corner. Thanks in part to the recent price reduction trend
in the industry, carriers have deemed it necessary to consolidate in order to offer more services
at a lower cost than their rivals. Overlapping networks have been consolidated into leaner, more
feature-rich versions of their previous selves, dramatically lowering the price small businesses
pay for the popular dynamic integrated T-carrier (T-1) lines that combine local voice and
high-speed Internet service into one connection.
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!"
Min Lieu owns a small insurance agency in Oklahoma. Five years ago he signed up with
XO Communications for a TDM-based integrated T1 line for $870/month, which did not
include local or long distance calling. Recently, he was offered XO's version of
a dynamic circuit called "XO Flex" for half of the price he was already paying.
"I would have been a fool not to take the deal" stated Mr. Lieu. "I'm able to
add headcount with additional voice lines, without any increase in expense or
degradation in high-speed Internet performance."
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.
According to a recent study conducted by PK Communications Telecom Brokers Inc., the average
cost of a POTS (plain old telephone service) line serviced by the Bells (AT&T, Verizon,
and Qwest) have changed very little over the 10 year span from 1996, the year the
Clinton Administration signed into law the Telecommunications Act, to 2006. The real
change in the industry came in the T-carrier class of products, where customers can
get up to 1.5 Mbps of bandwidth and 24 digital phone lines all in one package. Some
CLECs like XO, TelePacific, Nuvox, One Communications, and even Covad are now offering
rates well below the $550/month level, making the change seem like a no-brainer to
thousands of customers.
"What we're seeing here is the Bells holding their prices steady and milking their high
margins on POTS (plain old telephone service) lines for as long as possible. With the
lower prices being offered by CLECs (Competitive Local Exchange Carriers) on dynamic
integrated T-carrier services, the Bells are scrambling to keep pace before enterprises
realize they can actually save money by upgrading to bigger and more reliable circuits."
commented Don Rosebush, industry expert.
But how much longer will we continue to see improved technology, services, and prices?
It's all in the hands of the Federal Communications Commission, as they have the power
to sqwash the CLECs by proxy. No wonder AT&T and Verizon are the two biggest lobbying
powers in Washington. It makes you wonder what kind of services they would be able to
offer had they plowed that money into R&D instead of politics. Recent advances in technology, fostered by competition from growing CLECs, is bringing
integrated T1 services to small business everywhere. And the trend doesn't look like
it will change anytime soon. CLECs continue to grow their networks, offering more
advanced services like metro ethernet, MPLS, and more.
