What is EFM?

EFM (Ethernet First Mile) is a dedicated connection that gives you the speed and availability of a leased line, without the commitment or cost involved in installing a leased line. EFM provides the symmetrical upload and download speeds expected by businesses, making it ideal for VoIP, hosted solutions, video conferencing and streaming or sending/uploading large files to the Internet.

EFM avoids the large excess charges associated with traditional fibre, so you can reduce costs whilst boosting your connectivity.

You can expect to save as much as 60% on your existing leased line costs.

Who needs EFM?

  • Businesses that need a quick connection for critical applications
  • Businesses that require higher bandwidth without the commitment of a Leased Line
  • Businesses requiring a solution for voice, data and internet traffic
  • Businesses needed fast installation

How does EFM work?

EFM diagram

EFM runs over copper lines rather than the fibre used for other Ethernet services. The cost effective price comes from it using a combination of copper and fibre infrastructure. The first mile is the bonded copper connection between your premises and your local telephone exchange, with the remaining part of the network being fibre.

This offers a balance of reliability, found in copper lines, and speed, found in the fibre infrastructure.

We aim to install EFM within 15-40 days.

What speeds are available?

You can expect to receive dedicated and uncontended symmetrical speeds of up to 45Mbps both ways. This ensures you always have high-speed Internet at even the busiest of times.

How reliable is EFM?

EFM is very resilient due to its copper infrastructure. If you lose connectivity on one copper pair, the others remain live, retaining 75% of the bandwidth.
Our 7 hour fix time and 24/7 support means that we are always just a call away from fixing any issues.
