What is a T1 line?

A T1 internet line is a fiber optic internet line that carries data at a moderately fast rate of 1.44 megabits per second or 192,000 bits per second. The T1 line carries data approximately 60 percent faster than a home modem can.

A T1 line can effectively be split into 24 different channels for data and voice, making this an effective choice for small businesses and to be used in the home where different channels are required. T1 is a fast and efficient Internet connector that is cost-effective and secure. If you use the majority of the available channels for voice, your data speed can reduce. However, if you use the T1 channels for data, you will not see a variation in data speed.

How does T1 compare to other connection options?

The T1 Internet line is certainly not the only high speed option in the world of Internet connections. While the T1 is 60 percent faster than a standard home modem, there are some alternatives that are significantly faster. Some options that outperform the T1 line include the T3 line, which sends data at a rate of 43.232 megabits per second; the OC48 line, which transfers data at a speedy rate of 2.5 gigabits per second; and the OC192, which sends 9.6 gigabits of data per second. What you decide depends greatly upon your needs, and a general rule is that the faster the Internet line, the more expensive your out-of-pocket cost will be.

Why is T1 Internet a good option for small businesses?

The T1 line may not be the fastest Internet connector available on the market, but it is an excellent option for small businesses and private offices. Because the T1 allows up to 24 different channels for data and voice, it can easily be installed in a small business or office where multiple workstations will be in use at any given time.

An excellent example of an office that could effectively use a T1 line is an incoming call center or claims processing center. One T1 line will allow up to 24 different users, and it provides a reliable connection because one user's data usage will not slow the data transmission to other channels. The T1 is a great option for small businesses, private offices, and homes with many users that will need to connect to the Internet at the same time. Keep in mind, though, that if you plan to use the T1 option for your home, your monthly cost will be considerably higher than it would be if you chose a cable Internet provider.

There are many options when it comes to Internet connections, and the T1 line is just one example. Choose your Internet connection based upon your needs. T1 remains a great option for many because it is faster than a standard modem, easy to install, and provides added bandwidth for additional users. If the T1 fits into your budget, then it is an excellent Internet connector.
