t1 internet service is as ubiquitous as DVD players but the choices are much more varied. Ready to learn the basics and find a connections? In general, T-1 is a member of the T-carrier system. T-carrier is a communications system used for carrying voice and data transmissions in a digital format. T-1 meets the needs of businesses having multiple users on a system requiring fast speed and broad bandwidth. For a fixed monthly rate, businesses with 20 or more users can communicate via both voice and data. A Full T1 can accommodate as many as 24 users working at 64 Kbps.

'T-1 is made up of 24 digital channels. This requires a digital connection device (CSU/DSU {customer switching unit/digital switching unit}) to connect to four wires to carry the information. All T1 lines require that a Channel Service Unit (CSU) be connected between your Data Terminal Equipment (DTE), i.e., a personal computer, and the T-1 line. A CSU serves both as a surge protector (to protect your equipment from voltage anomalies such as lightning) and a monitor of the line itself.

As mentioned previously a T1 connection is capable of delivering 1.5Mbps. DSL connections are also capable of delivering this speed however they are not nearly as reliable as a T1 connections and should not be considered as a business connections unless it's SDSL and even then you will likely have some downtime. If you have critical information being hosted in your office or have a large number of users accessing the internet on a regular basis, consider getting a T1 connections. Also remember to get a professional's assistance when you search for your provider. Each company will tell you their connection is the best available but a broker will act as your agent and help you find what's right for you.

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
