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

Verona, Illinois, Aug. 15 /Daniel Johannesburg/ --
Business broadband, its price, and who can afford it, are changing. Every day an increasing number
of business are finding the new broadband services made available to them by the "new" telecommunications
companies that are emerging from the latest round of mergers and acquisitions. Overlapping networks
are being consolidated into bigger and leaner footprints, lowering the cost of dynamic integrated
digital signal 1 (DS1) service to the price range of about five regular phone lines. Small to medium
size business can now afford services once reserved for the Fortune 1000 companies.
The Integrated T1 line has two general flavors; analog and, of course, digital.
The term "trunk" is synonymous with an integrated T1 line, representing 24
bundled DS0 (regular 64KB) channels. Digital trunks form the basis technology
for dynamic integrated lines, which are capable of transporting digitized
versions of voice traffic in addition to regular data packets. This ability
of digital trunks to function in the data realm allows it the ability to
dynamically allocate traffic according to the application, allowing priority
for voice traffic and "re-claiming" that bandwidth for data transfer when the
phone call is completed. This ensures that none of the capacity of the
T1 line is ever wasted.
Illinois, 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.
"Commercial telecommunication providers were never on my Christmas card list"
commented Jake Chang, a small business owner in Denver, Colorado. "Dealing with them
meant erroneous bills, long wait times when trying to reach customer service, and
taxes I could never understand. Now that we migrated to a dynamic integrated
T1, my phone lines and high speed internet are bundled into one line with super
reliability. Not to mention the fact that XO Communications, a CLEC, treats me
like they actually want my business - not like I'm a pain in the you-know-what."
"For years I've played tug-o-war with the phone company who provided voice and data
service to my toy manufacturing company" commented Troy Bergfeld of Houston Texas.
"They kept trying to sell me services I didn't need, it took them months to finally
send me a correct bill, and I wasn't able to recapture bandwidth from my T1 line
when nobody was using the phone. Now that has all changed - my Telarus product
specialist recommending I give XO Communications a try. Now I use their FLEX T1
product and I pay less and get exactly what I want. I have even add another T1
seamlessly when the time comes for my business to expand."
"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.
With the help of super-CLECs like XO Communications, PAETEC, Nuvox, One Communications,
Cavalier Telephone, and TelePacific, small business owners everywhere now have access
to non-Bell service that is on par or better than those being offered by the former
Bells. Integrated T1s that do more and cost less have transformed into a solid beach
head for the newcomers. The only thing that can get in the way of future progress is the law. You know, the one
that requires the RBOCs to lease their local loops to CLECs at a reduced rate so that
the customer can get a dedicated connection between their office and the CLECs' network.
If the FCC decided to lift this requirement, this whole deck of cards could come down
in a hurry, and when it does, you can kiss dynamic integrated T1 service for under $500
good bye!
