A T-1, or DS1 line, is a private dedicated line that goes directly from your office or business to Accelerated Connections data centre, providing transmission at 1.544Mbps. 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.
Unlike Cable Internet, ISDN or a Dialup connection, a T1 line provides guaranteed bandwidth, since the line is not shared with other users
For voice & data, a T1 line can carry 24 digitized voice channels, or it can carry data at a rate of 1.544 megabits per second. If the T1 line is being used for telephone conversations, it plugs into the office's phone system. If it is carrying data it plugs into the network's router.
Types of T1 Connections...
Full T1:
As stated above, a Full T1 is a complete dedicated circuit of up to 1.544Mbps total speed. The full circuit can be either data or voice, but not both.
Fractional T1:
Fractional T1 is a private line providing a guaranteed transmission speed. Leased lines provide guaranteed bandwidth, since they are not shared with other users. Fractional T1 lines are cheaper than at full T1 (1.544Mbps). The most common fractional T1 speeds are 256 Kbps and 384 Kbps.
Point-to-Point T1:
A Point to Point T1 is the best application for such business applications as hosting web and email servers as well as and conducting audio and video conferencing over the Internet. Because point-to-point offers the most guaranteed dedicated connection available, this service is also recommended for companies transferring private files or using corporate VPNs and WANs.
Burstable T1:
A Burstable T1 service is the ideal solution for customers requiring very high bandwidth in bursts. The full T1 bandwidth is available all the time, but we tier our pricing so customers who typically use less than 512 Kbps of bandwidth pay a lower rate.
