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.

Frame Relay was developed to solve communication problems that other protocols could not: the increased need for higher speeds, an increased need for large bandwidth efficiency, particularly for clumping ("bursty" traffic), an increase in intelligent network devices that lower protocol processing, and the need to connect LANs and WANs. Like X.25, Frame Relay is a packet-switched protocol. But the Frame-Relay process is streamlined. There are significant differences that make Frame Relay a faster, more efficient form of networking. A Frame-Relay network doesn't perform error detection, which results in a considerably smaller amount of overhead and faster processing than X.25. Frame Relay is also protocol independent-it accepts data from many different protocols. This data is encapsulated by the Frame-Relay equipment, not the network.
'Today's LANs and computing equipment have the potential to run at much higher speeds and transfer very large quantities of data. With the diversity and complexity of today's networks, management can be a mammoth task if you don't have the proper tools. Each environment is a unique combination of equipment from different vendors. Frame Relay uses a packet-switching technology, similar to X.25, but is more efficient. As a result, it can make your networking quicker, simpler, and less costly.
Frame Relay sends information in packets called frames through a shared Frame-Relay network. Each frame contains all the information necessary to route it to the correct destination. So in effect, each endpoint can communicate with many destinations over one access link to the network. And instead of being allocated a fixed amount of bandwidth, Frame-Relay services offer a CIR (committed information rate) at which data is transmitted. But if traffic and your service agreement allow, data can burst above your committed rate. Since Frame Relay has a low overhead, it's a perfect fit for today's complex networks. You get several clear benefits: First, multiple logical connections can be sent over a single physical connection, reducing your internetworking costs. By reducing the amount of processing required, you get improved performance and response time. And because Frame Relay uses a simple link layer protocol, your equipment usually requires only software changes or simple hardware modifications, so you don't
