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

Portland, North Dakota, Sep. 03 /Olamide Lieberman/ --
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.
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.
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.
"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.
North Dakota, ordinarily not known for its telecom prowace, has been a hotbed
for businesses making the move to dynamic telecom lines. One local business
owner - Linda Peterson - who operates a travel agency, recently told us that
"I never expected the phone company to come out with anything that would
help me lower my costs. On the contrary. Ma Bell has had a history of raising
my rates and making my life difficult. When I heard about the XO Flex package
(offering 10 dynamic voice lines and 1.5 mbps of high speed Internet) at a price
of under $500, I couldn't move over fast enough." Since then Linda reported
a $150/month savings in her telecom expenses.
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. 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.
