Ethernet First Mile (EFM)

What is EFM (Ethernet First Mile)?

efm-business-broadband-octagon-lozengeEthernet First Mile (EFM) is simply a connection from the premises to the exchange; the connection is made up of multiple ‘bonded’ copper pairs. Unlike a traditional leased line which uses Fibre, EFM uses bundles of copper pairs meaning lower costs, high resilience and a faster installation time. Octagon’s EFM will give you an uncontended line using EFM technology. We know that your business requires a fast, reliable and cost effective internet access solution. With our EFM you’ll benefit from a dedicated connection that gives you the speed and availability you need, at a cost that suits your business.

With Octagon’s EFM leased lines, you’ll get internet access speeds ranging from 2Mbps up to 10Mbps, together with all the benefits of standard leased lines.

What EFM could mean for your business

We understand that when your internet connection goes down or is not as reliable as you’d like, your business can suffer. That’s why Octagon’s EFM offers you reliable, quick, uncontended and cost effective internet connection that’s perfect for you. Peace of mind with a supplier you can trust

Because EFM uses copper lines that are already in the ground, we don’t have to do the – sometimes costly – digging that we’d normally end up doing for a standard leased line. So, if you are in an EFM area and need a leased line service, you could benefit from:

Lower cost: EFM is up to 45% cheaper than our standard leased lines.

Faster installation time: we can get you connected in around half the time it takes for other leased lines

Save on Line rental costs.

You may have heard of SIP (Session Initiation Protocol). It’s a technology that allows you to make your calls over an IP connection, rather than the traditional phone network. This makes it easier to reduce costs of line rentals without compromising on quality.

We found the advice and support form Octagon in selecting a new phone system helpful when we were sourcing our new system.

The Ridge Medical Centre moved into a brand new purpose built premise and required a new telephone system to handle the large amount of calls they receive each day to provide a service that their patients would be happy with.
