  1. TI’s AR7:The Evolution of ADSL CPE to Fully Integrated SOC

  2. AR7 – First Single-Chip ADSL Router • Reduces subscriber churn for service providers • Improves user experience, especially for home networking • Adds subscribers that LECs previously couldn’t service • Provides up to 25% lower system cost than current solutions • Enables future proofing – supports today’s ADSL protocols and tomorrow’s increased throughput and reach protocols

  3. 7 Years of DSL Know-How Interoperability Testing We rigorously test our DSL solutions for interoperability to reduce operators’ risk and ramp to volume efforts Silicon Expertise We know what to test and how to test and we build that into our silicon Customer Knowledge We understand manufacturer and service provider requirements Broadband Portfolio In-house 802.11 and VoIP capabilities for easy add-on of additional features DSL Strengths End-to-End Experience TI has over 7 years of end-to-end experience deploying CPE and CO solutions – Over 20M ports shipped

  4. TI Is Committed to Single-Chip Solutions Wireless TI is committed to providing single-chip technology for wireless and wired communication • Advanced process technology (130nm and 90nm) • Digital and analog expertise Wired Single-Chip Bluetooth Single-Chip Cell Phone More to Come . . . Single-Chip DSL Router 4

  7. AR7 ADSL Router – System-View • Future proof ADSL– all standards on one chip • Annex A, B, C, I, J • ADSL2+, READSL • Greater than 50% increase in processor speed • Linux, VxWorks software support • Code compatible with AR5 • Single Power Supply • Integrated Ethernet PHY Vin V-Reg 12-18VDC CLK ENET XFMR RJ45 Hybrid (Transformer + Discretes) RJ11 USB UART GPIOs LEDs Serial I/F Gateway Ready Voice, PCI 802.11 SDRAM FLASH AR7 Enables Clean Board Layouts Component Count ~ 150

  8. AR7 Delivers on Market Requirements Service Provider Needs OEM Needs Consumer Demands Better wireless home networking Higher performance New services for increased revenue stream 20+Mbps ADSL2+ Robust interactive gaming without lag times Interoperability Lower latency for gaming Lower development cost Better out-of-the box experience $ Seamless and reliable accessibility to any application or service Lower system cost Real-time line diagnostics Programmable solutions Upgradeable products to meet evolving standards Faster downloads Quick time to market Faster data rates and longer reach

  9. 3X Improved Downstream Throughput with TurboDSLTM Packet Accelerator 3XPerformance Improvement DSL Downstream Throughput AR7 TurboDSL™ Packet Accelerator Existing Solutions Operator Benefits Consumer Benefits • Reduces buffering and lag-time for downloads • Enables video streaming and better home networking • Improves consumer’s experience and reduces churn • Lays groundwork for operators to benefit from home networking • Makes the triple play of voice, data and video services possible Results based on typical North American service provider agreements of 1.5 Mbps downstream and 128Kbps upstream.

  10. Expanding Service Providers’ Networks Ideal service provider coverage area from central office Actual coverage area Unserviceable areas from bridge taps, RFI, etc. Dynamic Adaptive Equalization With AR7 Today

  11. ADSL2+, Delivering Extended Rates • What the AR7 Provides: • First CPE solution to offer ADSL2+ • Standards Compliant Solution, plus supports proprietary ADSL2 install base • Software upgradeable to support higher bandwidths • ADSL2+: • Provides up to 20Mbps service at longer lengths than VDSL • TI wrote the ADSL2+ Standard • Need ADSL2+ support on both ends of the wire • Full Support of ADSL2 • - Offers packet support, reduced data overhead and higher network layer throughput • - Take advantage of the full benefits (dual ended line testing -- DELT, improved immunity to noise) • Seamless Transition into ADSL or READSL for longer loops
