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.
