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

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

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

Next Gen Needs for U.S. Operators

• Long loops and older loops, but natural
  deployment location at cross connect lt 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

• 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

• 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

• 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

TIs 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

• 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

UDSLs 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
