  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

  must leverage existing infrastructure
• Business case works!
• Payback in months, with 80 Carrier GM

5
Increasing Bandwidth for New Services

• Providers are meeting subscriber demand for more
  bandwidth with Carrier Ethernet Services
• MEF E-Line Services provide attractive leased
  line upgrade
• Less OPEX means more margin per line
• Ethernet Backhaul enables next generation
  applications and services
• 3G Cellular
• DVBH video phones

6
Carrier Ethernet Access

• Ethernet in the First Mile
• Enables widest availability for business Carrier
  Ethernet Services that extends beyond 1-10GBE
  Enterprise networks delivered via copper, fiber,
  coax and wireless technologies
• Creates an end-to-end Ethernet service both
  business and residential users
• Improved QoS for next generation IPTV, VoiP and
  data for residential users

The 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 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 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 arent 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
