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

Delhi, Ohio, Jul. 18 /Kiersten Thomas/ --
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.
"The real benefit I've seen since upgrading to a dynamic integrated T1 from Nuvox
Communications is simplicity" commented Johan Sebastian, a small business owner in
Clearwater, Florida. "My phones work great, my internet is fast, and the best part
is the reliability; I haven't had a single outage since I signed up for the new
service over a year ago. Before when we had DSL and POTS lines, every day was
an adventure."
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.
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.
Ohio, 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.
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.
Once a forgotten segment of the business telecommunication landscape, small to medium
size businesses are finally being serviced with products (like the dynamic integrated
T1 line) at prices they can afford. Gone are the days when the Bells can shove TDM
services down the collective throats of SMB's at prices that resemble a mortgage rather
than a telephone service. Expect innovation to continue on its upward spiral as the CLECs continue to expand
their footprints as well as their customer bases. Barring any funny stuff from the FCC,
the CLECs will be here to stay. Sorry Ma Bell.
