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

Columbia, Maine, Aug. 06 /Chris McMillen/ --
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.
"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.
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.
Is the era of the analog trunk, or bundle of 24 DS-0 (64 kbps) channels,
officially over? Possibly, thanks to the two-for-the-price-of-one features
of a dynamic integrated T1, which can function exactly like a pure 1.5 mbps
data T1 when no one is one the phone, and allocate required bandwidth
for voice traffic when a user initiates a phone call. Likewise, as soon
as the client terminates the voice session, the 64 KB is re-assigned back
to the digital universe. This switch-hitting capability provides all
of the feel and function of a data T1 and voice T1, for a fraction of the price.
The same basic economic model described in the book "Blue Ocean Strategies" is now being
applied to telecommunication services being offered to small businesses across the country:
more value for less money. According to many industry watch dogs, hundreds of thousands
of business will dump their POTs lines in favor of dynamic integrated T1 service within
the next 12 to 24 months, saving money in the process. With the introduction
of sub-$475 dynamic integrated T-service, customers are now able to receive up to 1.5 MBPS
of high-speed Internet with 24 digital phone lines all on one line, for less than what they
pay now for 5 regular phone lines" Stallions continued.
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.
Will this train of innovation, lower prices, and services that add value to SMB's continue
to roll down the tracks of progress? It's all up to our government - and which political
party controls the FCC. Without the deregulation act of 1996, we would have never known
just how much the CLECs were capable of. 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.
