Ethernet in the first mile

Ethernet in the First Mile (EFM)

EFM provides you with a high-quality alternative to traditional leased lines. Offering bandwidths between 2Mbps and 20Mbps, EFM is a scalable Ethernet service with dedicated connectivity and guaranteed service levels at a fraction of the cost of a legacy Leased Line service.

Reduced delivery lead times and ECCs

Each service operates over between 2 and 8 copper pairs bonded together. As the service uses copper tails, compared to Fibre Leased Lines delivery lead times are shorter at around 40 working days and the risk of high Excess Construction Charges (ECCs) is massively reduced

In-built resilience

If one or more circuits fail there isn’t a failure of the entire service. For further reassurance, our service is monitored 24/7 and offers up to a 9 hour target respond-and-repair time. An optional back-up service can also be provided for additional resilience

Maximum choice

Zed One uses multiple sources to provide EFM services, enabling you to select the access service, or combination of services, that best meets your requirements.

Business benefits

Delivered over bonded copper pairs

Inherently resilient and avoids the longer lead times and excess costs experienced with fibre based Ethernet.

Bandwidth is dedicated to you

No contention means you get guaranteed access speeds.

Back-up options available

Provide higher levels of resilience where site availability is critical.

24/7 monitoring and customer support

Fix problems quickly and minimise the impact on your business.

Fast repair times

Target repair times are 9 hours or less, much faster than traditional broadband services.

Network monitoring tools

Gain a better understanding of whether the service is being used efficiently or not.


Q: What is EFM?
A: EFM is short for Ethernet in the First Mile, which is a technology that enables multiple copper pairs to be bonded together to deliver an Ethernet service. It was developed as an alternative to using fibre based Ethernet as it offers a lower cost solution that also avoids the lead times and excess costs related to fibre delivery.

Q: Is the bandwidth based on a Committed Data Rate?
A: This will depend on the carrier used, as carriers either provide a symmetrical CDR or provide whatever the number of pairs can support (with minimum and indicative speeds quoted). The speed supported is a combination of number of pairs and length of copper.

Q: Can I upgrade bandwidth on an EFM service?
A: Upgrades can be done however these may require the addition of copper pairs.
