  1. Take-up of DSL technologies Tim Johnson Publisher www.point-topic.com January 2005

  2. Contents • VDSL and VDSL2 • ADSL2+ • Symmetric DSL www.point-topic.com Broadband History for BT

  3. Overlapping markets VDSL Symmetric DSL FTTB ADSL2+ www.point-topic.com Broadband History for BT

  4. VDSL and VDSL2

  5. Original VDSL: a technology going nowhere? • Big in Asia-Pacific • mainly distributing FTTB inside MTUs • 2.2m lines in Korea alone - but levelling off • large numbers in China (6m?) and Japan • Very little public network VDSL • old projects not being extended • few new ones identified (Belgium, Norway, Slovenia) • “substantially all” shipments into FTTB buildouts www.point-topic.com Broadband History for BT

  6. Even Korea Telecom’s VDSL growth has slackened off www.point-topic.com Broadband History for BT

  7. A case study in missing the bus • Too much too soon • early versions were “a solution looking for a problem” • leapfrogged by ADSL2+; newer technology, better suited to actual need • A marketing disaster • long, destructive standards battle • moribund industry associations • repeated failure to meet expectations www.point-topic.com Broadband History for BT

  8. Will VDSL2 be different? • Standard on a fast track? • first ratification Q3 2005; base standard soon after • driven by the US RBOCs; compromises to get agreement • Delivering 30Mbps up to 1.8km - eventually • What RBOCs need to offer full triple play? • two HiDef TV channels + data + VoIP • “A major technology in N. America in 2006” • Ramen Cohen, Metalink • Too disruptive for Europe? www.point-topic.com Broadband History for BT

  9. ADSL2+

  10. ADSL2+: the right technology at the right time? • Downstream speeds enough for realistic applications • Better range than original VDSL • Easier to integrate into an ADSL world • Annex J supports business symmetry requirement www.point-topic.com Broadband History for BT

  11. Leading-edge operators moving rapidly into ADSL2+ • Sweden and Norway • 60,000 ADSL2+ ports by end-2004 • Free (France) • migrating 1m customers to ADSL2+ “FreeBox” • 6Mbps downstream for Euro 30/month • Wanadoo (Netherlands) • 8Mbps/1Mbps for Euro88/month • BellSouth (USA) • will use ADSL2+ to trial a video offering www.point-topic.com Broadband History for BT

  12. Symmetric DSL

  13. Symmetric DSL: many choices, slow take-up • SDSL • proprietary, mainly USA • SHDSL • ITU standard, industrial strength, still a niche • Symmetrical ADSLs • ADSL2+ Annex J could be the preferred choice • VDSL • some business offerings in special situations? www.point-topic.com Broadband History for BT

  14. 1.2m Symmetric DSL lines worldwide by end-2004 Source: Point Topic www.point-topic.com Broadband History for BT

  15. Signs of stronger growth in future • Some uptick in business broadband in 2004 • Arrival of ADSL2+ should make symmetric broadband cheaper and easier • SHDSL still has technical advantages • IP VPN more recognised as the unifying platform for business applications • IP-over-Ethernet seen as the coming technology www.point-topic.com Broadband History for BT
