The Evolution of Integrated T1 Service

SHERWOOD, Maryland, Dec. 01 /Hunter Sheffield/ --
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.
From 1997 to 2007, the average cost of a POTS (plain old telephone service) line from the
Bells has hovered in the $50 - $80 per month price range. During this same time period,
integrated DS1 (digital signal 1) lines - which is the equivalent of 24 standard lines -
have come down in price from $1000 per month to $400. Small to medium size businesses
who have more than 5 phone lines can now actually save money by upgrading their service.
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 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.
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.
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.
