If you want a fast internet connection, one of the best services to look into is a T3 connection.  Also called a DS3 Connection, this high speed internet connection will ensure that you get the best services possible. 

Make sure that you look into all the different kinds of connections and the different DS3 services as well.   Fractional T3 service is dedicated service using a fraction of the full T3 capacity, for example, 512 Kbps. 768 Kbps, 1024 Kbps, etc.; Fractional DS3 service is service using a fraction of the full DS3 capacity, for example, 5 Mbps, 6 Mbps, 10 Mbps, etc.

It is additionally helpful to keep in mind that T3 services consist of fiber optic cable giving a total bandwidth of 155.52 Mbps, where 5.184 Mbps of this capacity is overhead.

T3 means the physical components used in DS3 service such as wires and jacks. DS3 is the electrical signal carried on a T3 circuit. A T3 is simply 24 DS-O circuits all bundled together into one circuit.

T3 service provides a dedicated connection from your premises to a local or long distance switch, providing you with a single high-capacity digital circuit for voice or data applications. With a DS3, there is a choice of allocating all of the DS-0 channels for data, for voice, or for any combination of the two.

Also, a carrier's implementation may limit this choice. The circuit is BI-directional and moves information simultaneously in both directions.  The best way to think about it is that a home telephone line is normally a DS-0 line.

The DS-0 is the building block of dedicated products. Dedicated service using two or more T3s tied together to effectively give a higher capacity line bonded T3 service.  If you are looking into different types, keep in mind that a boded T3 has 3 Mb x 3 Mb of capacity.

Usually, the bonded lines will come into a router specially configured to connect to the multiple T3s and to treat them as though they are one pipe.  If you are thinking about getting a DS3 connection, there are a few things that will prepare you to receive the best T3 service possible. 

DS0 is a non-switched dedicated service that can be provisioned as a private line point-to-point and multi-point service. DS-0 service allows full duplex transmission of voice, analog data and digital signals at speeds of 56 to 64 Kbps.

Burstable T3 and Burstable T3 Service "Burstable DS3" is similar to Fractional and Full T3, but the bandwidth is not dedicated; it is provided dynamically and might be cheaper. Although Burstable DS3 service can be cost effective, the typical pricing for Burstable T3 overage is so high that it usually makes more sense to purchase service at the next higher Fixed, Fractional, Full or Bonded T3 bandwidth.

Also, for high-speed Internet Access, you can allocate 24 channels to data, giving a two-way connection to the Internet at 1.544 Mbps. DS3 Internet connections range from $300 to $1000 per month, depending on the geographical distance between the customer and the long distance switch. Customers who will benefit from T3 data connections are typically businesses who need very reliable high speed internet connections.  T3 services are a smart plan for those who want to communicate cheap and with ease.
