EFM Leased Lines

Highly reliable 20Mb symmetrical Internet from £350.00 per month

EFM Leased Lines (Ethernet in the First Mile) provides high speed, reliable internet connectivity for businesses who have outgrown traditional broadband, but where fibre base Ethernet services are still too expensive.EFM uses multiple copper pairs to deliver the service. These are bonded together to provide a combined service. By combining pairs you will receive a much more reliable service because if there is a fault with a single wire then the service will just slow down, rather than taking your business off line.In addition, unlike ADSL where the customer is typically responsible for reporting a fault, with EFM the service is proactively managed by the Gradwell operations centre and where a fault occurs, it is quickly spotted and resolved.Finally, if there is a copper wire fault in the BT Openreach network, EFM is provided with “Service Level 4” which aims to have an engineer resolve the fault within 6 hours.

To order EFM, you will need to contact our sales team. Orders are subject to survey and take between 25 to 90 days to be delivered. EFM is available in 1500 of the most popular UK telephone exchanges and you can be upto approximately 4km from the exchange.

To use EFM, BT Openreach will install a number of analogue copper pairs and associated wall sockets. In addition an EFM network adaptor will be installed, which provides you with an Ethernet socket. You will need to have a spare power socket available within 1M of the BT sockets.

Upgrading EFM

It is not possible to upgrade from 2 Pair EFM to 4 Pair EFM or vice versa. Should you wish to upgrade in the future, you would have to cease your line and reinstall.

We can allow some overlap of the circuits to ensure that you do not lose connectivity in these circumstances, but this may be limited to the number of pairs available as exchange capacity may have changed from the time the original order was placed to the time you wish to upgrade.

Indicative speeds

Like ADSL, the speed an EFM circuit will run at will depend on your distance from the exchange. However, with EFM we can guarantee the minimum speed you will receive1. In our trials, we found that most customers receive a faster speed service than we can guarantee.

EFM is also a symmetrical service – meaning that both the upload and the download speed are the same. This is great if you are making Internet Telephony calls, using video, or sending / uploading large files to the internet.
