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.

The t1 line rates is a digital transmission service that can be used for carrying voice and/or data. A T1 connection is sometimes referred to as a "dedicated service" as the service is delivered to and from the customer premise from the CO (Central Office) without combining it with other traffic. A T1 connections is established by providing a "loop" or wire from the users premesis to the CO where the service provider has equipment. Part of the cost of a T1 is the "loop charge" or the monthly rental fee for the wire that is rented from the local phone company. Once the connection reaches the CO it can access the carriers network and reach any destination.

T-1 provides high speed, point-to-point digital transmission line (up to 1.544 Mbps). This can be used as a single high-speed data channel or it can be split into 24 channels and allocated to either voice or data applications. It is widely deployed and readily available in most regions and although the service is not deminished by distance from the CO, the price is sensitive to distance. This is due to the rental of the loop from the LEC (Local Exchante Carrier). T1 is currently the most common way that large companies connect their LAN to the rest of the world.

Are you ready for T1 service? You may be ready if you have critcal services that need a reliable connection to the internet. If you run ASP services, host e-mail servers or web servers, have over 20 people accessing the internet or use video on demand you should consider T1 access. While more expensive that DSL, T1 access is made to support the above applications. Also remember that when you begin shopping for T1 service you should partner with someone who will act as your agent and represent your best interests. Consider using a broker or agent to help you with your search and cut through some of the industry lingo to help you get exactly what you need.
