  1. DSL technology and deployment VDSL2 Contributed by Sascha Lindecke Director of Marketing Broadband Access Sascha.lindecke@infineon.com

  2. Today there are variousDSL Technology Options

  3. Existing High Speed Technologies Do Not Solve the Problem of Bottlenecks 100 Data rate [Mbit/s] Design only for short loop applications (MDU/MTU) 60 Real bit-rates are too low for multiple (3) HDTV channels VDSL 20 Low bit-rates are insufficient for Triple-Play applications ADSL2+ 8 2 SHDSL 1 km Line Length 2 km 3 km 4 km 5 km VDSL2 = VDSL Speeds with ADSL/2+ Reach and Flexibility

  4. VDSL2 Standardization • VDSL2 standardization started in January 2004 • Main technology development in ITU-T • North American system requirements in ANSI/NIPNAI • European system requirements in ETSI • Reached consent in May 2005 (Geneva Meeting)

  5. VDSL-2 Key Features • DMT modulation • Same as ADSL • Bandwidth increased from 12 MHz to 30 MHz • Up to 4096 tones (8x ADSL2+ !) • Worldwide Versatile Standard • 8 profiles defined for different services • Different bandplans for the regions • Variety of PSDs to optimize spectral compatibility • Support for a variety of services • Integrated Quality of Service features • ATM as well as Ethernet payload • Channel bonding for extended reach or rate

  6. VDSL2 – The DSL convergence technology • ADSL2+ • Coding • Framing • Long Reach • Upstream 0 • VDSL • Bandplans • Short Loops 1 2 3 4 • EFM • TC-Layer • Bonding • OaM • QoS • New Features • 100/100 Mbps • 30MHz • QoS

  7. VDSL2 -All The Benefits of ADSL/2+, Higher Speeds Than VDSL1 Criteria VDSL2 Benefits 12MHz VDSL1 30MHz VDSL2 VDSL1 None VDSL2 Mandatory 1km VDSL1 3km … VDSL2 VDSL1 None VDSL2 ADSL, ADSL2, ADSL2+ None VDSL1 Dual Latency, Dual Bearer, Pre-Emption VDSL2

  11. Phase 1: large installed base – ADSL/2+ DSLAM ADSL2+ Modem ADSL2+ Line Card ADSL2+ Modem ADSL2+ Modem Phase 2: DSLAM upgrade CPEs can "stay as they are" DSLAM ADSL2+ Modem VDSL2 Line Card ADSL2+ Modem ADSL2+ Modem Phase 3: selective upgrade of CPEs dependent on selected service DSLAM ADSL2+ Modem VDSL2 Modem VDSL2 Line Card ADSL2+ Modem VDSL2 Modem ADSL2+ backwards compatibility will make VDSL2 deployment scenario much more attractive for the Carriers and will speed up the technology adoption. ADSL2+ Backwards Compatibility
