What is a T3?

A T3 (sometimes referred to as a DS3) is a leased private dedicated line that goes directly from your office to an Internet Service Provider (ISP). A T3 / DS3 connection is equivalent to 28 T1 / DS1 connections and uses digital signals on fiber-optic cable at speeds of 45 million bps (bits per second) or 44.736 megabits per second. As a standard used in the North American and Japanese marketplaces, a T3 can handle 672, 64Kbps voice conversations or one video data channel. The T3 line has enough bandwidth to transmit full-motion real-time videos and very large databases over a busy network. Generally a T3 line would be installed as a major networking channel for a large corporation or university with high volume network traffic. Bandwidth for a Fractional T3, up to a full T3, generally run at speeds between 6 Mbps through 45 Mbps. Pricing on a T3 starts around $ 3700.00/mo +/- line & port charges.

Uses & Types of T3 Circuits

A T3 circuit is the ideal solution for businesses that require high-bandwidth access at a reasonable price. Whether you host high-traffic web sites, support web hosting or need high-capacity bandwidth on an as-needed basis, there's a level of T3 service (Full or fractional) that will meet your needs.

Fractional T3

Customers with other access options such as T1 lines can rapidly and easily switch their access solution to a single Fractional T3. Fractional T3 is more suitable for customers who expect their bandwidth requirements to increase steadily and/or continually in the near future.

Burstable T3

Burstable T3 is a dedicated point-to-point circuit from a customer's premises to an Internet hub. It is priced in billing tiers of 1.5 Mbps increments from 6 Mbps to 45 Mbps. As a Burstable T3 customer, you always have the full T3 bandwidth available over an unshared, non-fractional 45 Mbps digital leased line.
 

Tiered T3

For customers who have predictable bandwidth needs, the Tiered T3 is available in capped 3 Mbps increments and allows you to choose your usage level at a predetermined monthly cost.
