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

Telecommunications contracts can be much like a marriage and as we all know there are good and bad marriages. The fact is, when you enter into a telecommunications contract with a T1 provider for reasonalble amount of bandwidth or voice service you will have to enter into a long term contract. Telecommunications contracts for T1's and T3's typically range from 1 years to 3 years. Anything longer than a 3 year contract is usually only seen in very large applicatons like OC3 and OC12 or complex frame relay connections with many nodes. While the term of the contract will not be a problem if you have the right provider, the contract could prove extrememly burdomsome with the wrong provider.
We suggest using a broker to walk you through your options and show you the providers and services available. A broker or independent agent can help reduce the time it takes you to shop around for a T1 provider by asking you the questions once and searching through multiple providers to get the service that is right for you. The agent helps steer clear of the bias you will receive when speaking with one vendor as the agent will be paid no matter which service you choose. As the agent doesn't work with a specific provider like AT&T or Sprint, he or she will not push you in that direction if they are not right for you.
Remeber that the t1 provider you select will be your partner for quite some time so take caution in your decision. The worst part of being with a bad provider is the fact that it will affect your business. Dropped calls or an internet connection that goes down can be disastrous to a business. We found that the larger companies like AT&T and Sprint will release companies from long term contracts it if is shown that the voice or data T1 service was faulty on a regular basis, however the release from such a contract will not help recoup the damages of the lost calls and e-mails from the poor service. When shopping for a T1 provider we suggest using a broker and asking for referals from current customers to give you an indication of what you can expect.
