WW DSL Subscribers (000s)

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…

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

Multiple line card designs

Interop issues will be extensive with multiple standards

High level of development resources required

Carryover from existing designs

Creates Major Issues for Equipment Providers

5

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

VDSL – Limited for the Future

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

Fiber

Cross Connects:

In almost every neighborhood. At most 6000 ft from consumer. Each

holds about 600-800 consumer lines.

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

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

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

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

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
