ebrc Luxembourg Ethernet Exchange (LEX)

LEX aims at facilitating the business of the Ethernet Carrier Providers and at decreasing the interconnection cost.

LEX goals:

• Ease the interconnection processes by avoiding multiple negotiations about technical attributes and parameters


• Extend Ethernet services to end to end while maintaining the quality of service and the transparency of the Ethernet protocols

Instead of having to negotiate on a case-by-case base with other Ethernet Carriers Providers, creating a new interconnection is now a fastest and easiest process: LEX standardises the technical choices and ebrc acts as the sole technical contact.

Up to now, interconnections led to complex architectures requiring resources to keep them operational.

Using ebrc LEX dramatically improves the flexibility of your solution through faster provisioning processes and so, grants you more time to focus on your core business and your own challenges.

ebrc LEX offers three connection types:

  • Standard, with one ENNI interface
  • Protected Type I : two different ENNIs will be connected to two different cards within the same chassis
  • Protected Type II: two ENNIs will be connected to two different chassis. This protection level is not provided at the first stage but may be planned for future improvements

In a first stage, the LEX platform will be deployed in the ebrc Resilience Centre Luxembourg South (RCS) Data Centre, which is Tier IV classified. We expect that, in a near future, all ebrc’s Data Centres will be equipped with their own Ethernet Exchange Platform. The different sites will be connected to each other with a high speed backbone in a very efficient and resilient way.

The Carrier provider can have a physical presence within the ebrc carrier hotel: in such a case, a simple patching will be enough to connect with the LEX.

Through an international network, ENNI interface can be extended to the ebrc’s Meet-Me-Room from an external link based in any other carrier hotel facilities.
