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

Higher productivity for small to medium sized businesses is just around the corner thanks
to commercial grade broadband services that are now being delivered at a fraction of their
previous cost. Due to the ever increasing competitive marketplace and a mad dash to consolidate
networks, telecoms are offering their premium business services to small businesses for a fraction
of what they used to cost just a few years ago. Businesses who use more than four regular phone
lines can now upgrade to dynamic integrated T-carrier circuits for the same price.
At $50 to $75 per month, the average small business telephone customer could expect to pay
up to $750 for just 10 regular phone lines, which come with only a standard set of features
such as Voicemail, Caller ID, and Three-way calling. From 2000 to 2005, the cost of a
dynamic integrated T1 line was well over $800, making it an unattractive option from a
pure cost point of view. However, that paradigm has changed with the introduction of
sub-$400/month price plans and features that make the old POTs lines look pre-historic.
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.
To illustrate the types of decisions that small business owners are faced with
on a daily basis, we interviewed Glenda Probst, small business owner in Los
Angeles, California, about her recent move to a dynamic integrated T-1.
"I was in a quandary about how to go about expanding the number of voice
lines to my business. Before making the move to a dynamic integrated line,
I was using POTs lines. After the fifth line, my bill was above $300/month,
not including my $100/month DSL connection. Now, I have 12 pure digital
voice lines, 1.5 MB of broadband, and I pay under $400 for it. It was a major
upgrade in service with a reduction in total price. I only wish I'd learned
about this product sooner."
The adoption of any new telecommunications platform is never instantaneous. Many
technologies, like VoIP for example, have been in the works for years without
gaining much traction. Enterprises see communications as their life blood. Even
though many are becoming aware of newer, cheaper mediums by which they can conduct
business, the risk still outweighs the rewards in their minds. Couple the
'if it isn't broken, why fix it?' mind set with the telecom meltdown of the early
2000's and it isn't surprising that widespread adoption of new telecom services
has lagged. However, the new technologies of IP-based voice systems are finally
starting to gain an audience, and the chorus of satisfied customers continues to
grow. As this momentum pushes forward, so does general acceptance of it viability.
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.
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. 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.
