Market Status of DSL Technology

 DSL is the #1 Broadband Choice in the World with over 65% marketshare and more than 200 million users
DSL is available in every region of the world, and ADSL owns the majority of the market though VDSL and ADSL2plus are gaining ground
 DSL is capable of providing up to 100 Mbp, and supports voice, video and data.
 The new DSL network is IP-centric
There is broad equipment interoperability and there are currently established test specifications for ADSL,
ADSL2plus, SHDSL, and soon VDSL2 will join the list Finally, ADSL and home networking are a natural fit as DSL effectively supports multiple applications for multiple uses via each DSL connection.
 
Functional Elements Use of Bandwidth\ Channel Separation & POTS Splitter New IP-centric Architecture

POTS- Plain Old Telephone Service
 
TR-059 specifies IP Routed Network Architecture to support a mix of IP based services including IP Video from an Application Service Provider, by employing DiffServ.
ASP – Application Service Provider

Services now available
Better support of new applications
z Triple / Quad play is becoming a reality!
– ADSL2plus and VDSL2 both offer wide area
20+Mbps multi-channel speeds
Allows FTTC and direct from exchange service Full service residential 50Mbps by 10Mbps – max Wide area business Ethernet Feeder transport to remote nodes – using bonding 3 x HDTV (VDSL2), Internet, voice, gaming etc
z ADSL2plus and VDSL2
– With VDSL2 now approved:
Backward compatible with ADSL2plus etc Offers highly scalable networks Creates new flexibility for service providers Steadily take fibre closer to the subscriber
– Migrate ADSL → ADSL2plus → VDSL2 Easily implemented service expansion and upgrade
Most service providers update with a triple pack:
ADSL2, ADSL2plus and RE-ADSL at the same time
Or go straight to VDSL2
 
z 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)
– Bandwidth increased from 12 MHz to 30 MHz
– Up to 4096 tones (8x ADSL2plus!) Worldwide Versatile Standard
– 8 profiles defined for different services
– Different bandplans for the regions
– Variety of PSDs to optimize spectral compatibility
z Support for a variety of services
– Integrated Quality of Service features
– ATM as well as Ethernet payload
– Channel bonding for extended reach or rate

ADSL2plus backwards compatibility will make VDSL2 deployment scenario much more attractive for the Carriers and will speed up the technology adoption.
 
– Finalizing performance/functional requirements
(WT-114 and WT-115)
– Interoperability test plan for VDSL2 (PD-139) Enables efficient interoperability testing First plugfest planned for January 2006
z Ongoing test events with the interoperability test labs
Management
– Protocol Independent Object Model For Managing VDSL2
(WT-129) Based on ITU G.997.1 Adopting new objects from G.vdsl2
ADSL2plus and VDSL2 offer triple play at last
– Reach allows wider serving areas
– Rates allow triple play and enhanced services
– Ethernet rapidly taking over from ATM Offers LAN extension type services – no signal
conversion
– Network architecture evolving faster than ever before – Broadband Forum driven
