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

Bloomingdale, Ohio, Nov. 10 /Hunter Sheffield/ --
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.
"Even though we have been witnessing the re-consolidation of AT&T, we will never go
back to the dark ages of telecom where customers were stuck with bad customer service
and high prices" commented Troy Karlson, telecom analyst for e-STAR. "The competitive
local exchange carriers (CLECs), all whom own their own networks and compete directly
with the Bells, have created products such as dynamic T1 service that enables its
customers to connect to the Internet at 1.5 MBPS and have up to 24 regular voice lines,
packed with a feature-rich suite of add-ons, all for under what it costs to have
6 regular phone lines from Qwest/AT&T/Verizon.
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.
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.
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.
"The average cost of a business phone line from the Local Bell Operating Company (ILEC) has
remained constant for the past ten years" noted Edwin Jones, a senior market analyst and
telecom industry expert. "At the same time the prices of T-1 lines have declined from near
$1000 per month to a staggering $350. Keeping in mind that a T1 connection is the equivalent
of 24 regular phone lines all bundled into one, it comes as no surprise that demand for these
services in on the rise."
As the competitive local exchange carriers continue to compete by introducing new and
exciting products at prices most small businesses can afford, they are coming up against
increasing resistance from the RBOCs who are forces to lease their own copper lines
to these CLECs at reduced rates. This reality has the CLECs rushing to deploy their
own networks and fiber routes, but the FCC may ultimately relax the mandate - leaving
all of us wondering how long the party is going to last. 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.
