  2. IPNetwork TI Broadband - From Infrastructure to Endpoints Infrastructure Premises Endpoints Public Telephone Network Wireless LAN DSL Cable VoIP • Cable modems • DSL modems • Wi-Fi routers • Wi-Fi broadband gateways • Small/medium business and Enterprise voice gateways • DSL infrastructure products (central office, DLC, remote terminals) • Carrier-class Voice-over-IP gateways • Handhelds • Consumer electronics • PCs • IP phones

  3. Worldwide DSL Market – Full of Opportunity • DSL maintaining 70% share of broadband market worldwide for data services • VoIP services are starting to be provided by operators • Video is the next opportunity for DSL market growth… Source: TI estimates based on various industry reports ADSL ADSL2 ADSL2+ VDSL VDSL2

  4. Creates Major Issues for Equipment Providers • Multiple line card designs • Interop issues will be extensive with multiple standards • High level of development resources required • Carryover from existing designs Operators’ Next Generation DSL Battleground • Need to deliver maximum bandwidth and near ubiquitous coverage in a converged network • Video services (HDTV and PPV) • Near 100% coverage with data service • Managed networks • Voice services: convergence of various voice networks • Carrier Network Topologies are Changing • All major operators are shortening their loops • Deployment at wiring cross connect cabinets is starting • More deployments for MDU/in-building networks Video Voice Data * Video Voice Data * Video Voice Data * Video Voice Data

  5. VDSL – Limited for the Future • Today everyone thinks VDSL solves their problems, however it is limited • Requires Specific Line Cards in the CO • New CPEs need to be deployed • Limited Reach • Not Symmetric • Complicated Provisioning • Interoperability Problems TI’s Proposal – A DSL Platform Providing Universal Service Uni-DSL - UDSL ADSL ADSL2 ADSL2+ VDSL VDSL2

  6. Uni-DSL (UDSL) One DSL for Universal Service • Multicarrier solution based on DMT • Single chipset support of DMT standards • VDSL1, VDSL2, ADSL, ADSL2, ADSL2+, and Ultra-high speed DSL (UHDSL) • Ultra-high speed end to end solution up to 100 Mbps symmetric over existing wiring (200 Mbps aggregate) • Scalable 800 Mbps digital device for port density for DSL infrastructure • 4 ports at 100 Mbps symmetric or 200 Mbps aggregate • 8 ports at 50 Mbps symmetric or 100 Mbps aggregate Opt DS1 US1 DS2 US2 DS3 UDSL* f 0 138 kHz 3.75 MHz 5.2 MHz 8.5 MHz 12 MHz * Example spectrum; flexible spectrum allows any combinations of upstream and downstream

  7. UDSL Offers Support for All DSL Flavors Distance from the CPE 1 ft 1Kft – 3Kft 4Kft – 6Kft 18+ Kft 9Kft – 12Kft 300 ft – 500 ft Central Office Equipment Shelf Cross Connect/ Primary Connect Basement In Building MDU Neighborhood Wiring Pedestal Remote Terminal or Vault Home NID Remote DSL/ Short Loop DSL Short Loop IVD ADSL2+: Up to 24 Mbps ADSL2: 1.5 to 12 Mbps Long Haul IVD Next Generation DLC ADSL2+: Up to 24 Mbps ADSL2: 1.5 – 12 Mbps ADSL: 1.5 – 8 Mbps Traditional DSLAMs ADSL2: 1.5 – 12 Mbps ADSL: 1.5 – 8 Mbps READSL2: 192+ kbps Long Haul IVDs MDU Head End VDSL: Up to 52 Mbps UDSL: Up to 200 Mbps PON Termination (ONT) FTTU Various Home Networks VDSL Head End VDSL: Up to 52 Mbps ADSL/ADSL2 ADSL2+ Ultra High Speed DSL READSL2 Remote/Short Loop DSL Uni-DSL VDSL/VDSL2 FTTU

  8. Uni-DSL – A Universal Service Platform ADSL – up to 8 Mbps ADSL2+ – up to 24Mbps Fiber VDSL – up to 52Mbps UDSL equipment in the cross connect Ultra-high speed – 100Mbps symmetric Cross Connects: In almost every neighborhood. At most 6000 ft from consumer. Each holds about 600-800 consumer lines.

  9. Next Gen Needs for U.S. Operators • Long loops and older loops, but natural deployment location at cross connect < 6kft • Need migration path to 3 simultaneous HDTV channels over DSL (minimum) • Remote DSL from cross connect can potentially supply up to 20% of current voice subscribers, who are not reachable by ADSL today ADSL ADSL2 ADSL2+ VDSL VDSL2

  10. Next Gen Needs for Asian Operators • Korea • Maximum loop reach required is 1 km now • FTTC and FTTH is next step with VDSL or higher data rates • Japan • Fiber + VDSL is long term strategy for operators; most loops under 1 km • Fiber to the building with VDSL or 100baseT to provide 100 Mbps symmetric capability for data is needed • China • ADSL with Reach Extension now to improve coverage followed by ADSL2+, VDSL Video Voice Data * Video Voice Data * Video Voice Data * Video Voice Data

  11. Next Gen Needs for European Operators • France • Current video strategy focused on lower data rate DSL; i.e., 6 to 10 Mbps, solution for single channel SDTV over 3 km; eventual evolution to ADSL2+ for multi-channel • Italy • Incumbents are rolling out video service in 2004 to compete with CLEC (FastWeb) • Interested in high speed symmetric (10+ Mbps) offering to home and small business • UK • Primarily focused on providing data services and 100% coverage • Interested in deployment at primary connection points (cross connects) if political hurdles can be overcome • Starting to look at deep fiber deployment with VDSL • Germany • Longer loop plant than most others European operators; up to 4.2+ km • Concentrating on delivering data-only services at a relatively low data rate • Sees remote DSL as potential method to extend reach and lower cost ADSL ADSL2 ADSL2+ VDSL VDSL2

  12. TI’s Current UDSL Activities • Discussions with worldwide operators on concept • Strategic discussions with key customers • Potential to leverage incumbency and capture DSLAM/DLC market opportunities • Looking at standards activity • Have over 20 submissions into the standards bodies related to UDSL concepts • No one is at this level of leadership to drive universal services • Goal to make Uni-DSL an industry-wide effort to drive growth in the DSL market Video Voice Data * Video Voice Data * Video Voice Data * Video Voice Data

  13. UDSL Makes Video Over DSL Possible • Operators need an affordable option to support all of their network requirements and services • Uni-DSL (UDSL) provides support for ADSL, ADSL2, ADSL2+, VDSL, VDSL2 and a 100 Mbps symmetric ultra-high speed mode • Operators will be able to provide all DMT-based services off of one line card or home gateway, making deployment more affordable • TI is taking a leadership position in making video over DSL services a reality ADSL ADSL2 ADSL2+ VDSL VDSL2

  16. Performance Comparison: ADSL vs. VDSL

  17. UDSL’s Performance Enhancing Features • Bonding • Extend high data rate reach • Leverage excess copper pairs • Dynamic Spectrum Management (DSM) • Level 0 with AC7/AR7 • Levels 1 to 2 with software upgrade • Level 3 ideal in short loop and MDU type deployment with UDSL • Optimize transmission latency to match applications • Throughput improvements with priority queuing at the CPE • Multi-latency for voice vs. video vs. data
