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 is most like a leased line in terms of service delivered in that it offers a fixed speed connection, with no contention and in both up and down directions. The connection is delivered to the customer as a simple ethernet (RJ45) port.
Instead of being delivered over expensive fibre optic connections EFM is delivered over either 2 or 4 pairs of copper cabling from the exchange. This means costs are fixed depending on the number of pairs required; no more "subject to survey" issues!

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 receive. 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.
