A leased line is a dedicated, fixed-bandwidth, symmetric data connection. I'll explain what that means in a minute. What is a leased line used for? It is used to link two locations together.
A leased line is a dedicated, fixed-bandwidth, symmetric data connection. I'll explain what that means in a minute.
The first location is typically a corporate office. The second location is typically another corporate office, a data centre that’s connected to the Internet or a data centre that’s connected to the company’s existing Wide Area Network.

What is a leased line for? Carrying data and phone calls, typically from business premises such as this one.
By definition, leased lines are 'dedicated'. This means that all along the route of your leased line, the bandwidth you need has been reserved solely for your use.
Unlike consumer Internet connections, the bandwidth available does not fall at peak times, when other customers of the same ISP try to use their connections at the same time as youThis means they can upload data at the same fast speed at which they can download data. This can be useful if staff need to…
It’s common for companies to buy Internet access at the same time they buy a leased line. However, a leased line is NOT the same thing as an Internet connection.
Just as a pipe could be used to carry a number of different things (e.g. Water, gas, sewage), so a leased line can be used to carry a number of different types of data traffic (Internet traffic, phone calls, corporate VPN traffic). There’s no requirement to buy Internet access on a leased line.
If you DO get Internet access, there’s no requirement that you get enough to fill the leased line. For example, you might choose to get 15Mbit/s of Internet access on a 20Mbit/s leased line, which in turn could be provisioned over a 100Mbit/s circuit. You could use 5Mbit/s for WAN traffic and VoIP calls, and there would be 80Mbit/s spare for future usage.
2Mbps, 10Mbps and 100Mbps are the most popular connection speeds, though connections of 10,000 Mbit/s (10 Gigabits per second) are possible if money is no object.
What is a leased line likely to cost you? As a rough rule of thumb, 10Mbps connections cost twice as much as 2Mbps connections. And 100Mbps connections cost twice as much as 10Mbps connections.
