 Summary

• Service Providers and operators need to streamline their
  interconnect capabilities and processes for greater
  efficiency and fully-featured service offerings

• MEF specifications, certification and operational tools
  provide a common and efficient framework for
  standardized Carrier Ethernet Network interconnects

• Expanded global coverage via interconnects provides new
  revenue opportunities for service providers

• Implementation of Ethernet interconnects has begun and
  will rapidly accelerate in 2010

    Expanded Coverage – More Services
Example: Ethernet Virtual Private Line (EVPL) – via multiple partners
•   Carrier Ethernet service replacing Frame Relay or ATM services
•   From single physical connection (UNI) via multiple virtual connections to
    multiple physical connections (UNI)
•   MEF standardized Ethernet interconnects enable scalable delivery of EVPLs
    via multiple operators
