x. DSL – Spectral Allocation • Co-exists with legacy services Matthias Kindler 2002 -01 -27 Page 5

The ADSL Market • 16 million ADSL subscribers end of 2001 • Expected growth 02/01: 98% • Main growth is expected in Europe and Japan • ADSL is the dominant x. DSL Technology today • ADSL is the dominant Broadband Access Technology today Matthias Kindler 2002 -01 -27 Page 6 Source: Salomon. Smith Barney, March 2002

x. DSL - Distributing Broadband Services in the Building n x. DSL - Not only an Access Technology, but also for Inhouse data distribution over twisted-pair n 10 Base. S is: Ethernet over VDSL n 10 Base. S Features: – 10 Mbps symmetric Ethernet – VDSL robust performance – POTS/ISDN support – Reach up to 4000 ft/1200 m n 10 Base. S Typical Applications – MTU/MDU, hospitality – Fiber, Wireless, Cable LAN extension Matthias Kindler 2002 -01 -27 Page 7

Ethernet over VDSL - The Best of Both Worlds n Ethernet – Mature, low-cost, zero configuration – Minimal connectivity and service overhead – Quick roll-out, little provisioning n VDSL – Robust performance over single copper pair – Symmetrical and asymmetrical data transmission up to 26 Mbps – Reach up to 4000 ft/1200 m Matthias Kindler 2002 -01 -27 Page 8

Home Gateway - Value Chain Standard Groups Specific Challenges for Standard Groups Matthias Kindler 2002 -01 -27 Page 12 IC Supplier Specific Challenges for IC Supplier System House Specific Challenges for System Houses Service Provider Specific Challenges for Service Providers Customer’s Choice • The Customer’s choice leads to specific challenges and requirements for all parts of the value chain.

The Customer’s Choice leads to challenges. . . n … for the Service Provider – Customer has the responsibility for his own home network – Customer is confused with all the technology options – Customer wants data, voice and video services n … for the System House – flexible platform needed to be able to adopt fast to different or changing requirements n … for the IC supplier – (see next slide) n … for the standardization group – Time-to-market – Broad industry consensus required Matthias Kindler 2002 -01 -27 Page 13

The Customer’s Choice leads to challenges. . . n … for the IC Supplier – Deal with broad range of Broadband Access Technologies (not all will survive) – Deal with broad range of Home Networking Technologies (not all will survive) – Support of different services: Data, Voice or Video – HW and SW expertise required – ATM and Ethernet expertise necessary – More and more customers require security – Flexible Platform needed Matthias Kindler 2002 -01 -27 Page 14
