Ds3 Is Fast


If you need fast internet connection, one of the best things to do is to get a T-3 connection, which is a high-speed line, powered by DS3 technology that is capable of delivering 44.7 Mbps (44,700K) in both directions. For several years, the fastest, and most expensive way to connect to the outside world was through a DS1 or T1 connection. Now, a DS3 is more commonly used and not nearly as expensive as it used to be. Data Service Level 3 is the connection of choice for several large companies and places that require a large amount of bandwidth. DS3 technology is used for T3 lines and allows connections to the Internet to reach speeds of up to 44.736 megabits per second. A large company needs something more than a T1 line, and could probably use a T3 line powered by DS3 technology.

T-3 lines are used mainly by Internet Service Providers and large companies connecting to the Internet backbone and for the backbone itself. An ISDN has 2 DS0 lines plus signaling (16 kilobits per second), or 128 kilobits per second. A T1 has 1.544 megabits per second (24 DS0 lines) T3 - 43.232 megabits per second (28 T1s). OC3 - 155 megabits per second (84 T1s). OC12 is 622 megabits per second (4 OC3s), and OC48 - 2.5 gigabits per seconds (4 OC12s). OC192 is 9.6 gigabits per second (4 OC48s)

T3 connections are point-to-point dedicated lines that provide 672 64-Kbps voice or data channels or in other words 28 T1 lines. A T3 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 is 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 T3, 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 fur busty traffic but do not 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 T3 connection. Whether you are considering a colocation facility or a T3 to the door, make sure you use a broker to help guide you through the providers.
