Holmes County, Mississippi, May. 20 /David Onaindia/ -- Is there a resurgence in the popularity of telecommunications providers that compares with the late 1990's? The answer may surprise you. Since the crash of the Internet bubble, struggling telecoms have seen Darwin in action as many companies were forced with the choice of bankruptcy or forced consolidation. However, some companies chose the road less traveled: innovation. By offering customers more for less, many small to medium size business customers are finding that they can upgrade to integrated T1 service for the same cost of five regular phone lines.

The question remains, if this new technology is so progressive, why did it take over five years to gain broad appeal to SMB's across the country? One industry analyst from the Telecommunications Research Institute observed that many customers who consume commercial-grade phone service became very untrusting of telecom providers after the Internet bubble burst in 2000 and the MCI bankruptcy proceedings full of allegations of fraud and embezzlement. After all, no customer wants to come to work one day just to find out that their connection to the outside world has been shut down due to financially unstable service providers not being able to run a profitable or ethical business. Now, due to a series of acquisitions and mergers, the "survivors" are offering great products at rates that SMB's can't continue to ignore. The CLEC's and Bells are quickly gaining traction with the very important demographic.

The old-school integrated T-1 was analog in nature, and came with 24 configurable channels (called a trunk) which could be configured to carry either voice or data traffic. The new "dynamic" trunks are all-digital and can change on-the-fly to carry either data or voice traffic. This comes in handy when none of the voice lines are in use - all channels can revert to carrying data traffic, giving the end-use a full 1.5 MBPS of broadband. Each phone call requires only 64K of bandwidth, so even a small handful of calls only slows down the data connection by a nominal amount.

Is the era of the analog trunk, or bundle of 24 DS-0 (64 kbps) channels, officially over? Possibly, thanks to the two-for-the-price-of-one features of a dynamic integrated T1, which can function exactly like a pure 1.5 mbps data T1 when no one is one the phone, and allocate required bandwidth for voice traffic when a user initiates a phone call. Likewise, as soon as the client terminates the voice session, the 64 KB is re-assigned back to the digital universe. This switch-hitting capability provides all of the feel and function of a data T1 and voice T1, for a fraction of the price.

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.

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.

Hopefully the CLECs can continue to push the boundaries of innovation and economics. The only thing that can keep them from the promise land is the gatekeeper of competition: the Federal Communications Commission, and the huge Bells (AT&T and Verizon - that's you) who make it a point to spend more money lobbying in Washington DC than Exxon Mobile. Looking in the crystal ball of the future, it is clear that new an innovated services being offered by the few super-CLECs remaining will drive innovation higher and prices lower. New technology is being pressed to the forefront by lower prices that the mainstream of small businesses everywhere can comfortably afford.

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

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.

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.

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.
