EFM5 and EFM10 are both delivered from 5 Local Loop Unbundled exchanges in Edinburgh and Glasgow. Although BT copper pairs and exchanges are used, Pulsant provide the rest of the product which allows for a significantly higher level of performance, reliability and
quality on the service.
EFM uses a newer, faster version of SDSL combined with pair bonding to give speeds of up to 5Mbps for EFM5 (2 pairs) or up to 10Mbps for EFM10 (4 pairs).
EFM5 and EFM10 provide symmetrical internet access using G.SHDSL.bis (ITU G.991.2 (2004)) and IEEE 802.1ah.
Connection speed offered is up to 5Mbps (EFM5) or up to 10Mbps (EFM10). Actual speed delivered is dependant on length and quality of LLU copper between customer premises and local BT exchange.
Both products are provided at a 1:1 contention ratio, allowing you to take full advantage of high-speed applications such as video streaming, hosted applications and desktop sharing. Unlike
ADSL-provided access products, 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.
Pulsant will pro-actively monitor CPE equipment 24×7 to ensure layer 3 connectivity is available at all times.
Access to real-time traffic statistics for your connection to monitor bandwidth.
Pulsant offer EFM at customer premises served by the following Exchanges:
Leith, Rose Street & Waverley exchanges
Central & Douglas exchanges
EFM5 and EFM10 utilises the Pulsant Local Loop Unbundling network with G.SHDSL.bis termination. Each customer is provisioned either 2 copper pairs with an Actelis ML42 CPE (EFM5) or 4 copper pairs with ML624 CPE (EFM10). These then connect back to the exchange to an Actelis EFM
DSLAM (ML2300). The DSLAMs are layer 2 devices only and combine the multiple copper pairs into High Speed Links (HSLs). The DSLAM then VLANs the customer connections back to the local exchange IP switch which provides layer 3 routing. The exchanges are then backhauled to
the Pulsant network using high speed ethernet WAN links.
Pulsant monitor the client CPE, DSLAM, switch, backhaul and managed router (optional extra – provided at additional cost)
No POTS telephony is available on these copper pairs
Proactive support with Nagios monitoring of CPE provided by Pulsant’s 24×7 dedicated support team, backed up with a business-level SLA.
