Leased lines

A leased line is a permanent, dedicated high speed network connection, normally over a fibre optic cable between a customer site and a Supanet or Partner Point of Presence (POP). It is also called ‘private circuit ‘, ‘dedicated circuit ‘ or a T1/E1 line.

Versions of leased lines with lower capacity using Ethernet over copper are also available – see section on Ethernet First Mile. However most standard leased lines use Ethernet over fibre and offer very high capacities up to 1Gb.

Main Uses of a Leased Line
There are 3 main uses for leased lines:-

1.Data Transfer between two sites
A point to point leased line or private circuit allows you to connect two or more sites together over a secure, dedicated line. This allows you to extend your business network (WAN) across multiple locations with secure, fast and reliable data transfer. Networks can be established to provide intelligent routing, resilience and diagnostic features, when supported by multiplexers and data switches.

2.Provide Dedicated Internet Access
A common use of a leased line is to provide dedicated uncontended synchronous Internet Access to the business. Because you are not sharing your line with other users (it has a 1:1 contention ratio) you get guaranteed speed both up and down stream reduce buffering and lag in video conferencing and VoIP technologies. Thus more organisations are now using leased lines for internet access because they provide fast data transfer rates and are extremely cost effective when the internet is used heavily. See the section on Dedicated Internet Access (DIA).

3.Voice & Video Communications
A leased line can be used as a private voice or video network. In addition, links can be established direct from your site to a cellular network. Video – video conferencing is fully supported.

Main Features

Greater Bandwidth
One of the decisions you will make about your Point to Point leased line solution is the amount of bandwidth you want, this can range from 2Mpbs up to 1Gb, depending on what you need. The bandwidth is dedicated to you – not contended, and is the same both upstream and downstream. A choice of 3 bearers (10Mb, 100Mb and 1GB) various speeds e.g. 2Mb, 10Mb, 100Mb, 500MB, 1Gb and others. If you have 10MB speed on a 100MB bearer, you can increase your speed up to 100Mb without further installation. You would just pay extra line rental costs.

Better security
Your point to point line will offer a secure and direct connection between multiple sites. With broadband, SDSL or bonded DSL your data is going across a public network. With a point to point connection we will install a private line that connects you directly to your local exchange, keeping your data private and secure.

Reliable cross-site backup
The faster connectivity speeds and guaranteed uptime means that you can reliably transfer data between sites, allowing you to run backups across multiple sites. If reliable data backup is one of your chief requirements it is often worth considering a managed server.

Products & Costs
The costs for leased lines are variable depending on the distance between the customer site and the nearest Internet Point of Presence, and also the amount of bandwidth you require. Please contact Supanet staff for your requirements and we will provide a quotation.

Example applications

  • Links between major office locations to allow local area networks to work as one, providing email, collaborative working, internet and intranet access
  • Links between two PBXs (Private Branch Exchanges) so a single switchboard can manage all the telephone calls for two locations
  • Links between hospitals for the transmission of high resolution scans, x-rays and other medical images
  • Links between local area network users and servers based in a different location. This could include data storage servers, web servers or email servers

Leased Line – Questions & Answers

What is a leased line?
A leased line is a permanent, dedicated high speed network connection, normally over a fibre optic connection between a customer site and a Supanet or Partner Point of Presence (POP). It is also called ‘private circuit ‘, ‘dedicated circuit ‘ or a T1/E1 line.

Why would I need a leased line?
Leased lines are used mainly by businesses as a point to point data connection between sites or for high speed reliable Internet access 24 hours a day, seven days a week giving greater peace of mind. They offer dedicated, uncontended bandwidth ensuring that the maximum line speed is always available when required.

What speeds are available with a Leased Line from Supanet?
Our leased lines are available at speeds of 2Mbps to 1Gbps

How long will a leased line service take to install?
The lead time is 65 working days from date of order. The timeline will depend upon whether new fibre is required at your premises.

We have fibre at our premises; can this be used for the leased line service?
All quotations assume existing fibre is present and available for use, however, a site survey will still have to be carried out to ascertain whether the correct fibre is present and available for use. This can only be determined following order placement. Can the leased line service capacity be upgraded? Yes, up to the maximum speed of the bearer circuit (10Mbps, 100Mbps, or 1Gbps) subject to increased annual rental charges.

What equipment is needed to connect to the leased line service?
All our Leased Lines and Ethernet services are provided with a fully managed Cisco Router suitable for your service.

Do you offer a totally managed solution from Supanet?
Yes, we offer a fully managed leased line service. This incorporates management of the CPE and monitoring of the leased line circuit. However, we also offer an unmanaged service (wires only) for customers wishing to source and manage their own hardware.

How are Leased Lines and Ethernet priced?
The costs for leased lines are variable depending on the distance between the customer site and the nearest Internet Point of Presence, and also the amount of bandwidth you require. Our supplier network currently provides over 110 Points of Presence (POPs) throughout the UK.

What does bandwidth contention actually mean?
A 2 Mbps SDSL solution suffers a 1:10 bandwidth contention, this means that if there are 10 people in your area using the same service you will only get your original 2Mbps divided by 10. ADSL may have 1:20 or 1:50 contention ratios. With a leased line you get a 100% guaranteed 1:1 bandwidth ratio. This means you do not share a line with anybody else. Your leased line literally runs from your building to our network. With a leased line, you always have access to 100% of your line capacity – this means that if you purchase a 1Mbps leased line, then 100% of the time, 24×7 you get 1Mbps of bandwidth.
