  1. Making Mobile Backhaul 4G Ready Delivering Transitional Mobile Backhaul Solutions

  2. Enabling Mobile BroadbandADTRAN Mobile Backhaul Leadership Leadership in enabling mobile services over any access Dominant T1 backhaul provider in U.S.A. TDM (HDSLx), SONET(OPTI-6100), Ethernet (NetVanta/TA5000) Copper, Fiber, Microwave Focused on Ethernet backhaul for demanding IP services Ethernet over Fiber, GPON Resilient architectures Advanced Cos/ QoS features Innovation to drive down cost of delivering IP and legacy services Integrated tools/function to reduce cost Automated installation processes Simplified operational models Packet/ Ethernet based timing

  3. Mobile TV is here i.TV 2.0 for iPhone coming soon Enjoy full NBC videos on your iPhone CBS releases TV.com iPhone app Hulu coming to the iPhone? 4G technology being deployed Rivals Wireline Broadband speeds VzW deploying LTE Sprint/Clearwire WiMAX All WSP have 4G plans for 2010-2013 Mobile Broadband is here 10X bandwidth w/o corresponding profit TV program watched on Smart Phone Evolution from 2G  3G  4G

  4. Revenue and OpEx were once linear. Voice and text messages drove majority of current revenue as well as majority of backhaul impact. All you can Eat Pricing Models drives demand to lower cost per bit delivered to user Revenue per bit delivered is driven to lowest levels. Significantly expand data capacity to enable new devices, services and applications  ARPU growth LTE is 1st generation wireless network built as a data network Mobile Broadband hammers ProfitabilityData usage way up; disproportionate ARPU Source: Light Reading

  5. Demand for Next-Gen Mobile Backhaul Ethernet Access Missing link to Profitability • Wireless (Mobile) Network Operators moving to Packet-networks drive down Operational Cost • Core Networks and Applications Infrastructure have moved to packet, IP/MPLS upgrades. • First Packet-based RF technologies being deployed at cell sites • Mobile Backhaul Access last hold-out to All-Packet Network Realization 100s or 1000s of Base Stations served LTE is Packet IMS and EPC are packet Mobile Backhaul (Access) Connection needs to be Packet Mobile Telephone Switching Offices (MTSO)

  6. Hybrid Backhaul ModelBaby step toward All-IP Convergence Key backhaul transformation required for 4G (LTE) LTE forecast to be 80%+ of traffic, 50 – 100Mbps required Desire to freeze, decouple TDM leased line growth Leaves Voice Network Undisturbed - Revenue Protection No changes to Network Timing, Operational Processes Internet IP/Ethernet Circuit Core TDM/SDH Packet Core PSTN Service Cell Site Access & Aggregation Central Office/Mobile Core 2G 3G Two Networks 4G PDSN Aggregation: 2G: SDH/FIber 3G: ATM/SDH 3G: ML-PPP/SDH 4G: Ethernet over GE Fiber Access: 2G: T1/E1 (PDH) 3G: ATM IMA/PDH 3G: ML-PPP/PDH 4G: Ethernet over X Cost /bit HA Backhaul Scale

  7. Key Attributes for an Ethernet NTURobust enough for Mobile Backhaul Low Cost/Scalable Bandwidth Ethernet over Fiber (EoF) – first choice 4G/LTE Bandwidth, 100Mbps+ 10x increase in data rate, 1Gbps through-put available Time to Market for Service Ubiquity, Every cell site must be served. 2011 launch EoF not everywhere, can use alternative EoX Allows Services Convergence Path to all-packet architecture Retire leased lines, integral sync capabilities SLA Management CoS support e.g. Real-time vs. Best-Effort Resiliency 99.99% service availability Hardened for cell site deployment Robust operating range, metallic interface protection All-IP

  8. A Cell site is not a Wiring ClosetFlexible mounting/powering options In BTS or eNB enclosures Single RMU in size In CO or Street Cabinet NEBS, IEC compliance In uncontrolled environments Temperature hardened Near Tower Surge protected/isolated interfaces e.g. cell site is a lightning rod No space, rack or GR-487 cabinet Rack as well as wall mounting options OSP options +24V & -48VDC powering options Resilient, Dual feed powering LTE eNB OSP EAD

  9. Fiber cell sites grow in all regions The number and portion of cell sites with fiber grows in each region in each year through 2013, and won’t stop there

  10. EoCu, EoTDM, EoF, EoS equals EoXCompleting the customer reach puzzle • EoCu – Ethernet over Copper • Optimized bandwidth per loop • Perfect for short to medium length loops • Requires local deployments & loop access • EoTDM – Ethernet over TDM • Predictable bandwidth per circuit • Time to Market effective deployments • Minimizes CapEx by centralizing aggregation platform • EoF - Ethernet over Fiber • Active Ethernet for higher rate business services • PON for cost-effective SOHO service offer • EoS - Ethernet over SONET/SDH • Outstanding reputation • Resiliency • Proven TDM/Synchronization for mobile backhaul

  11.

  15. Pseudowire and Circuit EmulationRequired for all-IP backhaul Bridge 2G, 3G services a.k.a Circuit Emulation or Pseudowire ATM IMA (UMTS) support TDM (GSM, CDMA) support ML-PPP (EV-DO, HSPA) support SAToP DS1 or E1 over Packet ITU Y.1453, RFC 4553, MEF 8 CESoPSN DSO visibility ITU Y.1453, IETF pwe3-cesopsn, MEF 8 ATM IMA over E1/T1 Backhaul over SAToP ATM PW saves DCS ports

  16. Traditional Network Timing Distro Sync Networks Deliver … Sync. Very well. ;p GNSS/GPS Primary Reference Source • Frequency • Phase • Time-of-Day T1/E1 Secondary Reference Source Traceability SONET/SDH Network SONET/SDH or PDH T1/E1 SONET/SDH • Frequency

  17. Three Aspects of Synchronization Frequency This is what SONET/SDH delivers today All that’s needed for the vast majority of network services Synchronous Ethernet is an excellent replacement for SONET/SDH based sync distribution Phase Required by Time Division Duplex (TDD) based mobile solutions Beyond the capabilities of PHY based sync distribution (SONET/SDH or SyncE) Today, typically delivered by GPS/Satellite 1588v2 can provide this requirement in band Time-of-Day Required for a CDMA2000 operation 1588v2 can provide this requirement in band

  18. Key: Not Breaking the Sync ChainConsiderations of Migrating Standards
