What is Leased Line?Dedicated and Shared Leased Line

A leased line is a telecommunications link between two points that are leased from a telecommunications provider, such as a telephone company. A leased line is a private, point-to-point connection between two sites over a network infrastructure. It allows you to connect your local area network (LAN) to another site or location that is connected to the internet at speeds of up to 20/20Mbps.

A leased line can transmit a huge amount of data. For example, 20Mbps leased line can send a 1GB file at the rate of 200MB/s. It’s faster than most internet connections. Now you don’t have to wait for hours to upload or download even big-size files over the internet. There are two main types of leased lines: dedicated and shared.

Dedicated Leased Line

A dedicated leased line provides a private, uninterrupted connection between the two points. This is ideal for businesses that need to send or receive large amounts of data. While dedicated leasing is more expensive, it provides faster speeds and higher priority than shared lines.

Shared Leased Line

A shared leased line is used by multiple customers at once, but each has access to the full bandwidth of the line. This type of service is particularly useful for companies that don’t need constant connectivity between two or more locations, as they can share the line and save money. However, as it is shared, speeds may be slower than with a dedicated line.

When deciding between a shared or dedicated leased line, businesses should consider how much data they need to send and receive, as well as how important speed and reliability are. Those who need a high-bandwidth connection should opt for a dedicated line, while those who only need occasional connectivity can save money with a shared line.

When it comes to choosing between a dedicated and shared leased line, there are a few factors to consider:


A dedicated leased line is more expensive than a shared leased line, as it provides you with exclusive use of the bandwidth. If you only require a shared line, this will be cheaper than a dedicated one.

Organizational Requirements

Whether your organization requires the excess capacity offered by a dedicated line is an issue to consider. If you don’t need it all of the time, but occasionally experience heavy traffic demands or if you wish to reduce latency for mission-critical applications, a dedicated line may be the right choice for you.

How Dedicated Leased Line Works

A dedicated leased line provides you with exclusive use of the bandwidth either between two sites or across a wide area. A key benefit is that you are not affected by network congestion due to other users accessing the connection at the same time as your organization, and since there are no additional costs associated with your usage, this is one of the most cost-effective ways to get a high-bandwidth connection.

Dedicated leased lines can be used for a variety of applications that require high bandwidth. Including video conferencing, transferring large files, and VoIP telephony. They are also ideal for organizations with critical applications that need to be delivered with low latency.

How Shared Leased Line Works

A shared leased line provides your organization with a connection to the Internet or private network. This is used by multiple organizations within one building, across an entire campus, or via an ISP, for example. It implies that you are sharing bandwidth with other users of the service. This means there may be times when it will be congested due to high usage across the entire connection. If you only require a shared line, this will be cheaper than a dedicated one.

We recommend that organizations considering the use of a shared leased line evaluate their network traffic patterns to ensure that using such an arrangement is appropriate for their business needs. One way to do this is by setting up Quality of Service (QoS) rules that guarantee certain applications.
