EFM Ethernet First Mile.

Product Overview

Description

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).

Functionality

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.

Availability

Pulsant offer EFM at customer premises served by the following Exchanges:

Edinburgh

Leith, Rose Street & Waverley exchanges

Glasgow

Central & Douglas exchanges

Technical Specifications

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

Support

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

Configuration Guide

Once the line has been ordered Pulsant will configure the line as follows:-

 

  • Prior to the delivery of the LLU circuits by BT, Pulsant will send a EFM modem to site along with a straightforward install guide. Once BT have installed the circuits on our behalf, simply call our Managed Services team on 0845 11 99 999 to arrange activation of the service.
  • If you have opted to take a Managed Firewall Router service, our support team at Pulsant will ensure that your IP address allocation meets your needs
  • If have not opted for a managed service, you will be supplied with a routed subnet of 5 usable addresses but more can be added for no extra cost if there is justification by simply submitting a request to our support team via the my.pulsant.co.uk portal or by email – our service provisioning team will advise when the request will need to be made to ensure it is ready when your new EFM service is activated. Further allocations can be made at any time.

Your IT support will then be able to connect the services to your existing IT infrastructure.

FAQ

How do I access traffic graphs?

If you are one of the nominated contacts for the service you will have access to the Pulsant customer area. The traffic graphs are viewable under the particular service.

How does Pulsant monitor my line?

We use a system called Nagios which continually monitors the status of your EFM line, 24 hours a day, 7 days a week. If we detect a problem with the line we will be able to start diagnostics of the service. We will then contact your technical representative.

What speeds are available?

Our EFM service is available at speeds of up to 5 or 10mbps. Actual speed delivered is dependant on length and quality of LLU copper between customer premises and local BT exchange.

My line appears to be down. How can I check this and what to do?

A simple check is to run a traceroute or ping to one of our nameservers – ns0.pulsant.co.uk for example. If this test fails give our 24 hour support line a call on 0845 11 99 999. The line will be monitored by Pulsant and we will be aware if the line is not in service.

How long does it take to provision a new EFM service?

There is a minimum 20 working day lead-time on new EFMs.

What is the SLA for this service?

Firstly there is a 30 minute initial response time SLA for new faults, and we endeavour to have a fix in place within 4 hours. These time frames are dependant on site access availability.

In addition to this we also provide a 99.87% uptime guarantee with a pro rata rebate should we fail to meet it
