At most 6000 ft from consumer. Each holds about 600-800 consumer lines. Next Gen Needs for U.S. Operators:  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 Next Gen Needs for Asian Operators:  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 Next Gen Needs for European Operators:  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 TI’s Current UDSL Activities:  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 UDSL Makes Video Over DSL Possible:  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 Back Up:  Back Up Performance Comparison: ADSL vs VDSL:  Performance Comparison: ADSL vs VDSL Performance Comparison: ADSL vs. VDSL:  Performance Comparison: ADSL vs. VDSL UDSL’s Performance Enhancing Features:  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
