3 Existing High Speed Technologies Do Not Solve the Problem of Bottlenecks Data rate [Mbit/s] VDSL Line Length 1 km 2 km 3 km4 km5 km ADSL2+ SHDSL Low bit-rates are insufficient for Triple-Play applications Real bit-rates are too low for multiple (3) HDTV channels Design only for short loop applications (MDU/MTU) 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
