A T1 line refers to a specific type of fiber optic telephone line that can carry more data than traditional copper telephone lines although a T1 line might be made out of copper too. The T1 line creates a “pipe” capable of blowing through larger data streams. The business is charged for one T1 line, rather than eight (or more) separate telephone lines. The cost of a T1 line can be expensive, but prices are dropping as demand grows. A T1 connection is a VERY FAST connection to the Internet. The connection is always active. With a T1 line, you can provide dozens of computers with Internet access without modems, telephone lines, and dialup accounts for each one. T1 connection speed is a matter of attraction for all the internet users. It has become the synonym for high speed dedicated voice and data transfer. The connection is also perfect for small and medium sized businesses needing an internet service provider for 20 to 50 internet users. It is a high-speed physical connection capable of transmitting data at a rate of 1.5 million bps (bits per second). It is now a popular option for businesses connecting to the Internet.
Generally speaking, a T1 line is not cost-effective for individual or residential use. In this case DSL or cable service is a better choice. Small businesses and government will benefit most from a dedicated T1 line.
