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.

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.
