Drivers for Ethernet Access Drivers for Ethernet Access
• Very large unaddressed market– $8.2B/year in service revenues in U.S. alone– T1/E1s are not a cost-effective way to serve more
than 3 Mbps
• Technology is mature– Standards are ratified with large international
deployments• Tier 1, Tier 2, CLEC and Independents
• Ethernet is the choice– No other future protocols on the horizon
• Competition is still there– Wire line faces cable, wireless threats –
must leverage existing infrastructure
• Business case works!– Payback in months, with ~80% Carrier GM

The Ethernet AdvantageThe Ethernet Advantage
• Ethernet provides the bandwidth required to support next generation applications and services
• Ethernet Access completes the connection– End to end Ethernet provides the most efficient, lowest cost
access method for extending Ethernet Metro networks
• Broad set of media and topologies supported by the standards– IEEE 802.3ah – Copper, Fiber– Hybrid Fiber Coax and Wireless
• Adherence to standards ensure consistent delivery of Ethernet access services
26
MEF Certifications Program: Access TechnologiesMEF Certifications Program: Access Technologies
• The MEF Certification Program will address access technologies to ensure conformance with Carrier Ethernet attributes
• The initial phase will address the conformance to IEEE 802.3ah OAM standard for Ethernet in the First Mile (EFM) in delivering Ethernet services via copper, fiber and EPON access
• The initial phase also includes wireless Ethernet mesh access certification testing, based on forthcoming IEEE 802.11T, ensuring total coverage and mobility of Ethernet services
• Liaison with Cable Labs looking towards aligning Ethernet over HFC work with MEF specifications
27
Certification Leads to InteroperabilityCertification Leads to Interoperability
• Lets vendors cooperate to build complementary “end-to-end” solutions– Metro Core, Aggregation and Access Edge offerings– Providers have their own supplier ecosystem in place and aren’t
looking for a whole new solution
• Interoperability among vendors leads to more favorable market conditions– Interoperability provides a wealth of choices– Lowers the barrier of entry to new markets or applications by
reducing the attraction of proprietary architectures
