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

The way business connect to the digital universe is changing. More and more enterprises are
discovering the new broadband options made available to them through a series of cost cutting
measures by telecommunication providers. With the recent rush to consolidate, more and more
features are being crammed into the current service offerings, which continue to fall in price
bringing products like integrated T1 service into the price range of the vast majority of
small to medium-size businesses.
"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.
One might think that, given the cost - benefit analysis of the integrated T1 value
proposition, more businesses would be changing over to the new platform. However,
the rate of adaptation is rather slow. Rob Butler, head of the Telecommunications
Research Institute, thinks that "phone companies have a problem with trust amongst
their user base. For many years, customers have dealt with increasing rates, long
hold times, and frustration in general. Now, it appears, the ice is finally starting
to melt and customers are opening themselves up to new technology.
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.
Dynamic integrated T1s are a fairly new phenomenon. Unlike their analog
counterparts that can never deviate from their initial set up configurations,
dynamic T1s are able to convert voice phone calls into data packets and
them prioritize their delivery through an all-digital trunk. The ability
to break everything down into the lowest common denominator (digital)
allows the system to change on-the-fly to reclaim phone lines for high
speed Internet the second the phone call is terminated. An integrated T1 essentially
provides the end user the same service as one data T1 line and one
voice T1 line, for half the cost.
Integrated T1s comes in two basic configurations: digital and analog trunks, with a trunk
being a 24-line (or channel) bundle. The newer, digital trunks, however, are able to
run both voice and data over the same channels. By assigning priority to the voice
traffic whenever it is present, a dynamic integrated trunk can provide the end-user
with a full 1.5 MBPS of data throughput if no phone calls are in progress. As more
voice lines are required, less data lines are available. Analog trunks are all
pre-assigned to either voice or data traffic, and do not reconfigure in the event
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. The golden age of telecommunications may be upon us, based upon our research and
recent uptick in customer satisfaction. Although the industry has years of
bad blood to overcome, recent innovations such as the dynamically configuring
T1 line are proof that progress is indeed being made.
