T-3: What you need to know

Used for voice and data transfers, a T3 line is a reliable high-speed dedicated line. It uses a digital signal utilizing fiber or copper wires. The data rate of transfer can reach up to 43.332 Mbps, greater than most modems are capable of transferring.

If you do the math, you will find that a single T3 line is equivalent to 28 T1 lines. Each T1 line is capable of accommodating 24 channels that can transfer both data and voice. The T1 terminates into the telephone room on a jack called a smart jack.

It then extends out into the data or telephone equipment using simple fiber cable. It has two pairs of fiber connections that are used to connect all channels to you. So you can expect that this type of line will only accommodate a small space, much less than most standard copper trunks would require.

The 24 channels in the T1 line can be used by multiple users. It utilizes these channels effectively by allowing another user to use a channel that is free.

A typical T1 line is capable of accommodating 50 up to 100 users without any problems. Intense phone applications like used in contact centers will need additional T1 lines to accommodate it.

If you obviously need more channels, then the T3 line is a more efficient choice. You can get an increased bandwidth to help you accommodate all kinds of applications.

Another service that is common to most household is the DSL connection. The Digital Subscriber Line is a slower circuit than the T1 or T3 lines and it is not dedicated. It is ideal for individual use since it runs on your current telephone line.

On the other hand, a T1 circuit is a dedicated service that used for most businesses. It has a faster and more reliable connection than the DSL, allowing for more complicated and advanced applications to be used. If you are looking for a more reliable service for your small business, the T1 is more suitable and advisable.

Campus environments and other large organizations or companies can utilize the T3 line to provide service. Data and voice transfers are not a problem as long as it is configured to do so.

It is best that before you decide on which service to use, you should determine your usage for both your data and voice communications. Knowing these helps you gauge the kind of service you will need for you business.

You need to understand the current applications that you use as well as consider future applications you might want to incorporate into your system. Consider your future growth as well when you decide on the right service to take up.

T3 lines are more expensive, but you need to consider the amount of costs you can save up compared to using the standard copper trunks. Actually, the costs for these lines have steadily been decreasing these past years.

A primary reason is that most central offices are now updated and can accommodate these services without any problem. Another relevant factor is competition offered by many providers today.

With the T3 line, the installation cost may be high, but your ROI will definitely be higher.
