South Bend, Nebraska, Aug. 22 /Richard Anderson/ -- 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.

Nebraska is a place that we found was a hot spot for small business owners making the move over to dynamic T-1 lines. One business owner that we interviewed gave glowing reviews of his move to TelePacific's "OnePac" dynamic product. Keith Gray explained "I used to have a regular integrated T1 with 10 voice lines and 14 data channels. When no one was using the phone in my office, we were limited to just 896 KB of bandwidth. After searching on the Internet for better options, I found that I could reduce my price from $850/month to $500/month, and at the same time have 14 voice lines and 1.5 mbps of broadband. I didn't take long for me to pull the trigger and make the change."

"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."

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.

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.

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.

The recent progress made by CLECs leaves us thinking in hypotheticals. "What if the Clinton administration wouldn't have passed the Telecommunications Act of 1996, requiring RBOCs to lease their lines at reduces rates to the CLECs?" "Will the FCC continue to enforce this law, or will it be overturned by the powerful AT&T and Verizon lobbyists?" It is impossible to know either way, but for the time being we can just be grateful that the industry has evolved to the point were small businesses can actually benefit from telecommunications at an affordable rate. Recent advances in technology, fostered by competition from growing CLECs, is bringing integrated T1 services to small business everywhere. And the trend doesn't look like it will change anytime soon. CLECs continue to grow their networks, offering more advanced services like metro ethernet, MPLS, and more.

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 South Bend 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. - 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 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.
