Product Overview


National EFM is delivered from 800 BT exchanges in the UK.  As with LLU EFM, BT provide the copper pairs required (anywhere between 1 and 8 pairs), but unlike LLU EFM BT can also provide services via fibre where copper service is not available or not capable of providing the
bandwidth required.

The service will be provided as ethernet and provide only internet access (i.e. national EFM cannot be used for point to point connections without the use of a VPN).

EFM uses a newer, faster version of SDSL combined with pair bonding to give speeds of between 1Mbps and 1Gbps.


National EFM provides symmetrical internet access using G.SHDSL.bis (ITU G.991.2 (2004)) and IEEE 802.1ah for copper and 802.1 ethernet for fibre connections.

Connection speed offered is from 1Mbps up to 1Gbps.

All National EFM connections are provided at a 1:1 contention ratio, allowing customers to take full advantage of high-speed applications such as video streaming, hosted applications and desktop sharing. Unlike ADSL-provided access products, National EFM provides bandwidth
symmetrically which enables services which rely on two-way communication such as Virtual Private Networks, Voice over IP and video conferencing.

Fixed IP provided as standard, along with the option of routed subnets at no additional cost..

Up to 5 free DNS hostings are also provided.

All copper circuits will be ordered with Etherway standard SLA which offers a 24 clock hours resolution target.  All fibre connections have a 5 clock hours resolution target.

Pulsant will pro-actively monitor CPE equipment 24×7 to ensure layer 3 connectivity is available at all times.


Proactive support with Nagios monitoring of CPE provided by Pulsant’s 24×7 dedicated support team, backed up with a business-level SLA.
