5. Carrier Ethernet Defined Carrier Ethernet is: A ubiquitous, standardized, carrier-class Service and Network Defined by five attributesthat distinguish it from familiar LAN based Ethernet

6. Carrier Ethernet Scope and Reach Enterprise Clients Small/Medium Business SoHo & Residential Triple-Play Mobile data/video Internet information & Software apps HD TV, TVoD, VoD, Content Providers Host applications, Consolidated Servers Voice/Video Telephony Gaming, DR, ERP Video Source Carrier Ethernet Carrier Ethernet wire-line and mobile backhaul with copper, fiber , cable, wireless access network delivery

7. Carrier Ethernet for Mission Critical Applications Carrier Ethernet brings significant business benefits to mission critical applications • Top Market Sectors • Healthcare, finance, education, government, media • Principal Applications • Site-to-site access, server consolidation, business continuity / disaster recovery, software as a service (SaaS), service orientated architecture (SOA), Internet access, distributed imagining, converged networking • Benefits • Scalability, control, reliability, performance, data center & server consolidation, expedites and enables new applications • Cost reduction, revenue acceleration

8. Worldwide Business Ethernet Services Worldwide revenue for Business Ethernet Services mounts steadily to nearly $31 billion by 2012. • Robust enterprise customer demand is projected for the next five years, with double-digit annual growth across all geographic regional markets: Asia/Pacific, EMEA, U.S., and ROW. • Service providers throughout the world are committed to Ethernet as the future ubiquitous standard for network service connectivity. • Ethernet equipment vendors are actively enabling this important transition. • Customer accessibility to fiber facilities is the top challenge to worldwide growth of Ethernet services. • Detailed market statistics are available through Vertical Systems Group’s ENS Research Programs(www.verticalsystems.com). Business applications for Ethernet Services include Dedicated Internet Access (DIA), Ethernet Private Lines, Ethernet LAN / VPLS, and Ethernet access to other network services (e.g., IP/MPLS VPNs, Frame Relay, etc.).

9. Ethernet Services + MSOs = Success! Carrier Ethernet enabled applications, Simple technology, Certified, ubiquitous services are key and ideal for mid market expansion for MSO and Cable Operators

16. MEF 18 Certification (1st announced companies June 18th) • MEF 18 provides standard testing of Circuit Emulation Services over Ethernet • Speeds implementation and enables full inter-operability • 334 ground breaking tests and certification in the suite • MEF 18 has many applications but is key to Mobile Backhaul migration strategies • Lead by strong service provider demand • Industry first impairment testing brings first test of emulation of clock recovery • Raise the level of confidence that clock recovery will meet the stringent requirements. • Comparison with ITU 8261 • ITU 8261 does not define a profile that allows a deterministic and repeatable test • MEF 18 Certification: the first test bed to produce repeatable results

17. Why a Certification Program? Assures service providers that Carrier Ethernet Equipment complies with MEF Specifications Assures enterprises that Certified Carrier Ethernet services will perform to defined service level specifications – minimizes risk Facilitates migration to Carrier Ethernet – Assurance that SP Carrier Ethernet offering is reliable and supports converged applications “Are you MEF compliant?” frequently seen in RFP’s June 18, 2008 MEF 9, MEF 14, MEF 18 for Equipment Manufacturers MEF 9, MEF 14, for Service Providers Approaching 500 systems and services certified 19 service providers, 59 equipment manufacturers

18. New Global Services Directory • Business Users • Find Carrier Ethernet services anywhere in the world. • Service Providers (Carriers/MSOs) • Find a partner to build a global Carrier Ethernet service.

19. Carrier Ethernet for Mobile Backhaul • Carrier Ethernet • Economically meets exploding bandwidth requirements currently constrained by the prohibitive costs of legacy networks • Leverages rapid move to Carrier Ethernet for wire-line traffic enabling a single integrated wire-line and mobile backhaul network • Much easier for service providers to manage and maintain • Most mobile traffic is broadband/IP centric • Carrier Ethernet is optimized for packet data traffic • Overcomes TDM (T1/E1) services scalability • This alone makes Carrier Ethernet the compelling choice • Time/urgency • Carrier Ethernet removes the barrier to timely progress
