Leased Line Jargon Busting

Although more and more businesses are now opting for a leased line over a broadband, a leased line is still not considered to be a ‘standard’ choice for businesses; for companies to have a dedicated leased line is still very much a relatively new concept. Because of this, it’s often much more difficult to find valuable leased line information than it is to find out about different broadband products, for example, and many businesses may find themselves getting muddled with all the different jargon being used.

Don’t panic! A leased line doesn’t have to be complex, complicated, or stressful. Here’s your handy guide to leased line jargon, giving you all the information you need to select the right internet product for you:

Upload Speed
The available speed for uploading data from your PC to the web. Upload speed is becoming increasingly important as more and more businesses use cloud computing and voIP services on a day-to-day basis.

Download Speed
The available speed for downloading data from the web to your PC. Fast download speeds have always been essential for business, and yet many aren’t receiving the speeds they need with ADSL connections.

Committed Data Rate
The upload and download speeds that you have agreed to receive from your leased line provider. Depending on your contract, you may be able to raise or lower the data rate easily as your needs change.

Symmetrical Connection
A leased line should always provide a symmetrical connection, which means that upload and download speeds are the same. With broadband, download speeds are often much faster than upload speeds.

Mbps
Measurement used for leased line speed. Many leased line contracts are available with speeds varying between 2 Mbps and 100 Mbps, or 10 Gbps. The right speed for you will depend on your personal needs.

Bearer
This is the line that is used to connect your premises. In some cases, the bearer may be capable of transferring more data than you’ve selected, making upgrades easier, cheaper, and more convenient.

Service Availability
Leased line products are known for their reliability, which is why many providers publish their service availability – how often you can expect a reliable connection. It should usually be between 99 and 100%.

SLA
This stands for Service Level Agreement, and is a set of guidelines that a leased line provider must attempt to adhere to with regard to service. SLA often states how quickly leased line faults must be fixed.

Contention Ratio
A leased line is a dedicated connection, which means it has a 1:1 contention ratio and is not shared with any other users. For comparison, broadband connections often come with a 50:1 contention ratio.

Latency
Low latency is a huge advantage of a leased line. The lower the latency, the smaller the time gap between a command and a reaction, which is why a leased line is recommended for financial traders.
