A T1 line is a type of leased phone line that can transmit approximately 1.5 Megabits per second (Mbps) over copper wire or 45 Mbps over fiber optic cable. It’s the most common type of leased line for businesses and it’s available from both telco companies and internet providers.
A T1 Line works best if you need to carry lots of data, such as video or voice transmissions. For example, a company might use a T1 Line to connect two offices together over long distances because it can handle high volumes of data transmission without slowing down as a standard broadband connection would do.
The term T1 Line is used to describe both the fiber optic and copper lines.
A T1 line provides a dedicated channel that only you can use. Because your data travels over its own private connection, it ensures that your voice or data transmissions never get delayed because of other users on the network. The dedicated nature of T1 lines is their biggest advantage for businesses using them for data transmission.
When choosing among different kinds of leased lines, consider how much money you can afford to spend per month because prices vary depending on what speed you need. Also determine if you want to lease a fiber optic cable or CO (Copper) cable line, taking into account the fact that modern phone systems will only with fiber optics so there is no need to purchase a copper line anymore.
Do not confuse T1 Line with DSL services. They are entirely different technologies that provide two completely different types of transmission speeds. A T1 line is usually used for business purposes and provides consistent speeds, while DSL service starts out at lower speeds but can vary depending on how far away you are from the local telephone company’s office.
