A T1 line is a type of telephone line. It is made of copper or fiber optic material, which enables it to transmit more data than the standard telephone line. It is often called the T-carrier line.
Most T1 lines are made of twisted copper. This has been the industry practice for several decades. However, many lines are now in the process of being upgraded to fiber optic lines, which use bundled glass fibers.
The T1 line has helped usher in the information superhighway. Typical lines can only send data at the speed of 30 kbps (or 30 kilo-bits per second). The T1 line, on th other hand, allows the transmission of 1.544 megabits per second, and can handle 24 digitized voice channels. T2 lines can transfer up to 44.736 megabits per second.
It is crucial for networking computers and is even 60 times more powerful than a typical modem. Commercial buildings also need T1 lines for their complex phone service. In fact, those who have more than 8 phone lines will actually save in the long run when they invest in a dedicated T1 line. They only pay for one line, and get Internet service as well.
The cost of T1 line depends on how far the company is located from the telcom operator. Prices are also becoming more affordable as the demand for T1 increases. It is not practical for regular consumers, on the other hand. They would be better off getting a DSL or cable service, which can meet their Internet needs for a lower cost.
In Europe, the industry standard uses another carrier line, labeled E1 and E3, and the less common E2.
