Leased Lines UK has a multi-layer national network based on optical fibre and microwave with CISCO BPX and IGX carrier class switches.

This follows a complete migration from the original Microwave based ATM ring. This presents a network designed to be:

• Scalable, providing the ability to increase capacity where it is needed as well as extending geographical reach.
• Resilient, with a highly meshed architecture so that inter-site link failures are not noticed by customers.
• Reliable, utilising carrier class equipment and redundancy to maintain service.
• The core network uses proven ATM and Frame Relay technologies upon which IP services can be carried.
• Leased Lines UK operates the network to provide Virtual Private Networking (VPN) for its customers as well as providing connectivity to the Internet.

Leased Lines UK occupies three locations in London Docklands. The heart of the network is Telehouse, which provides our connection to other Internet Service Providers (ISPs) either via the London Internet Exchange (LINX) or through other partner Internet transit providers.

The national network has core IP switching centres in four locations. Each of these locations has a choice of targeting one of the three London sites for access to the Internet. Consequently in the unlikely event of a problem in one or even two of the London sites, connectivity to the Internet will be maintained. An independently provisioned fibre ring affords IP layer resilience between the three London sites.

International Network Infrastructure

Leased Lines UK provides enhanced connectivity, hosting and private network services within Europe. The network connects into the U.S. via two high capacity transatlantic 622Mbps links and extends into continental Europe with peering points in Amsterdam, Frankfurt, and Paris.

The company provides customers with extensive International connectivity through its partners Tier 1 status and multiple peering points in Europe and the USA. To ensure maximum resilience, Leased Lines UK's London core routing centres connect into the US via two separately provisioned resilient transatlantic links.
