If a T1 service isn't enough to meet your needs, you can choose from the Tier 1 service providers' comprehensive t3 line (DS-3) service options. This high-speed line is offered in variables of up to 45 Mbps (from 3 Mbps to 45 Mbps or just 45 Mbps, depending on your needs) of continuous bandwidth so you can optimize the response time of your Web site, transfer large video files, or offer regional Internet access. We found 5 service providers that offer great plans. The first plan we found was with ACC Business. ACC uses the ATT network exclusively and is at the top when it comes to reliability. At ACC you'll get the realiability you would expect from ATT without the price.

Sprint also came up high in our review of T3 service plans. Sprint offers an incredible SLA (Service Level Agreement) with their service standing behind the product they offer 100%. While this may seem like something all providers do, further research will show that not all providers offer an SLA like Sprint. The third provider offering a great T3 plan is Telepacific. Unfortunately Telepacific is a regional player and only offers service in California and Las Vegas. Because of their focus they are extremely specialized and offer incredible customer support and reliability. If you're not in California you may consider moving there just to get this service!

The fourth plan we found and highly recommend is Telarus. Telarus is a reseller for Global Crossing, Qwest, and Wiltel. While you will get the value of the underlying provider you will not pay the price you would going in the front door. Telarus buys in bulk from these networks and transfers on the cost savings to its customers. Telarus is a virtual provider so you will not have extra hops to the network. You jump right on from your local CO and don't have to worry about extra latency! The final plan we suggest in our top 5 is Savvis. Savis offers Tier 1 service and highly reliable customer service. While they have a limited footprint, once you're on the network you'll have one of the best services around.

A t3 connection is a point-to-point dedicated line that provides 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 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 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 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 T3 connection. Whether you're considering a colocations facility or a T3 to the door, make sure you use a broker to help guide you through the providers and plans available.
