 DS3 Connection FAQ
Written by: Patrick Oborn - Jan 7, 2009
A DS3 connection is a point-to-point dedicated line that provides 672 64-Kbps voice or data channels or in other words, equal to 28 T1 lines. A DS3 is used to transmit digital signals at 44.736 megabits per second and has enough bandwidth to transmit full-motion real-time video, and very large databases over a busy network. A T3 line would be installed as a major networking channel for a large corporation or university with high volume network traffic.
When you need more capacity, you often have to buy it in the next available increment, which may end up costing more than you want or can afford to spend. Worse yet, with current, "bursty" application requirements, the need for additional bandwidth can often be as temporary as it is critical. By providing flexible capacity, or "bandwidth on demand," service providers can help customers deal with variations in traffic, and with avoiding a high fixed monthly payment. True bandwidth-on-demand services should allow for a wide range in capacity.
Although anybody can purchase a burstable DS3, this type of connection can be costly, even as costly as a full 45Mbps connections. Burstable lines can be found at their lowest cost at a colocation facility. At a colocation facility, or "colo", many users share a large OC3 or OC12 pipe. As a customer you will not have to pay for a the fixed cost of such a large pipe, but will have the benefit of being able to burst up to very high speeds if necessary. If you need the reliability of a large pipe for busty traffic but don't have the capital, consider a colo. If you have a steady volume and are consistent, you may consider keeping services in house and going with a DS3 connection. Whether you're considering a colocations facility or a DS3 to the door, make sure you use a broker to help guide you through the providers and plans available.
