What is a T1 (DS1)?
A T1 transfers data between two points at 1.544 Mbps symmetrically, and is ideal
for customers who need a high-speed connectivity to the Internet or as one link
in their virtual or real private network. A T1 connection provides roughly 60
times more data than a normal residential modem. It is also extremely reliable,
much more reliable than an analog modem. Depending on what they are doing, a T1
line can generally handle quite a few people. For general browsing, hundreds of
users are easily able to share a T1 line comfortably. Most small Internet
providers have a T1 (or a fractional T1) line as their connection to the
Internet. In addition, a T1 connection is a dedicated link and unlike ISDN and
analog modem connections, the T1 connection is up 24 hours a day.
Why a T1 when Business DSL (SDSL) is much cheaper?
T1 circuits are transported over a more robust channel. DSL is designed to be a
lower cost alternative to the more traditional data communications product, such
as Frame Relay and T1's. One of the ways this lower cost is achieved is by
having DSL circuits share more of the data transport infrastructure. With 1.5
Mbps SDSL, your data traffic shares the connection with other DSL circuits
running at slower speeds. On the other hand, a T1 line is dedicated to
transporting only T1 traffic. Another note of importance is that an SDSL line is
not only slower than a T1, but SDSL is not currently available everywhere. A T1
is much more readily available and downtime maintenance is better and faster.
This is a must for any business that depends on the internet to survive!
For faster speeds, T1 lines can be combined to create a T3 connection (it takes 28 T1 lines to make one T3). A full T3 is 45 megabits/sec. For further information on a T3 (DS3) circuit connection- click here.
At ISP-Select we are able to offer several different T1 service options
(depending on availability to your area). Prices and service options may vary
from one provider to another.
