The Future of DSL


Overview Review the obstacles the industry faces on the road to successful

DSL deployment in the mass market Standards-based DSL Interoperability Spectrum Management Customer service and technical support challenges Automated provisioning and flow through of all orders Limitations posed by Digital Loop Carriers DSL in a Box: Getting to True Plug-N-Play Results of IEC/Hellerstein & Associates Broadband Access Survey


Standards Based DSL

Benefits of using a standards-based DSL Lack of standards leads to market fragmentation, low volumes, and

high cost Promotes interoperability of DSL technologies and devices and leads

to increased customer choice Allows the market to provide more product and supplier alternatives

than possible without a standard Helps focus industry on resolving other challenges necessary to

reach mass deployment Lowers costs to suppliers and to consumers Increases choice of providers and greater selection of products


Standards Based DSL Variants

Asymmetric and Symmetric ADSL and G.LiteHDSL2 and G. Shdsl


Standards Based DSL Variants (continued)

G.Shdsl Emerging ITU standard,decision expected by Feb 2001 Spectrally compatible with ADSL and other technologies Rate adaptive form of HDSL2 Longer reach Single pair (2 wire) Speeds from 324K to 2.3 Mbps

HDSL2 ITU decision on standard expected by the end of 2000 An improved version of HDSL that requires only one copper pair Symmetric solution that is spectrally compatible with ADSL Superior reach, up to 24,000 feet


Interoperability Interoperability is key, both among different DSL technologies and

among equipment providers Two key groups have played important roles in promoting

Interoperability DSL Forum

A non-profit organization of over 300 companies representing all of the leading stakeholders in DSL

Interoperability demonstrations at SuperCom University of New Hampshire’s Interoperability lab

Both hold frequent plugfests to test interoperability of equipment and technology amongst a large collection of companies in the same room

University of New Hampshire (UNH) Interoperability Lab hosts two DSL consortiums: ADSL and HDSL2 http://www.iol.unh.edu/consortiums/index.html


DSL Forum

DSL Forum Interoperability Working Group and the UNH Interoperability Lab hold frequent plugfests

G8 Interoperability Group 8, Members working to develop a long term framework for accelerating interoperability and providing leadership at ongoing plugfests

Initial focus is on G.Lite and Full rate ADSL Developed a framework for facilitating interoperability and

driving towards certification Testing is currently taking place on an accelerated

schedule


Interoperability

Interoperability is a critical first step in getting to certification

Next service providers need to provide their deployment models so that products can be tested and certified.

Deployment Council Newest group, just was launched a the recent

DSL Forum Meeting in Dublin


Spectrum Compatibility and Management

Along with Interoperability, Spectrum Compatibility and Management is a crucial issue that needs to be addressed Development of spectrum compatibility standards is essential to reduce

cross talk and other forms of spectrum interference Recent FCC Rulings on Spectrum Compatibility and Management

Definition of spectrum compatibility and spectrum management as well as other key terms, such as “significantly degrade”.

Spectrum compatibility is defined as the ability of a loop technology to reside and operate in the same or adjacent binder group as another loop technology

Spectrum Management is defined as the administration of the loop plant, to prevent harmful interference between services and technologies that use pairs in the same cable.

FCC defined significantly degrade as any action that noticeably impairs a service from a user’s perspective.


Spectrum Compatibility and Management (continued)

FCC Order sets the ground rules for spectrum compatibility and management but defers to the T1E1.4 Committee of ANSI to create spectrum compatibility standards and management practices

The Network Reliability and Interoperability Council (NRIC) was charged with advising the FCC and offering recommendations of the necessary policy changes the FCC must make


Overcoming the Obstacles to a Bright Future

Self Installation Automated provisioning systems and processes Flow through of all orders for every provider whether

CLEC, DLEC, ILEC, or ISP Provide customer and technical support personnel with all

the tools needed to resolve problems


Customer Service and Technical Support

Customer Service and Technical Support Provide service reps with the information, training, and access

to resources to help them do their job and to troubleshoot Answer the phones quickly

Reduce time customers spend waiting to speak with a technician to less than five minutes

Follow through with all customer requests Better tracking of all orders Notify consumers of all actions that affect deployment of DSL

Stop the blame game--Take responsibility


Overcoming the Obstacles to a Bright Future (continued)

Digital Loop Carriers Today over 50% of all US households are either served through a

DLC or are too far from the Central Office

DLC History First Generation DLCs, including pre-first generation UDLCs,

began to be deployed in the 1980s and early 1990s Next Generation DLCs began to be deployed in the early 1990s New Remote Terminals are just beginning to be deployed today.


Overcoming the Obstacles to a Bright Future: DLC

What solutions are available to reach these people served through a DLC Upgrading existing DLCs to the Next Generation DLCs that can offer

DSL service as SBC is doing under Project Pronto SBC is decreasing loop length by having 80% of all consumers no further

than 12,000 feet from the CO, sometimes even as low as 9,000 feet SBC hopes to be able to serve 80% of all customers once it completes its

upgrades Attaching mini-rams to existing DLCs Collocation in existing and in adjacent structures Virtual collocation


Overcoming the Obstacles to a Bright Future: DLC (continued)

Regulatory issues concerning the ability of competitors to collocate in or adjacent to a remote terminal


DSL in the Box: Getting to True Plug-N-Play

OpenDSL Consortium formed in August 2000 New group spearheaded by Cisco & composed of DSL equipment and chip

manufacturers, system integrators, and service providers whose goal is to simplify and expedite DSL installations and make equipment interoperable

Focus on self installation thereby avoiding expensive truck rolls Getting to true plug and play

Automate CPE configuration, network elements, and setup process Make customer installs and set-ups of modems and routers easy and simple Ability to switch service providers without need to purchase new modem

OpenDSL Certification Program and Lab Place where vendors can test their equipment for interoperability and to ensure true

plug and play Third party certification of equipment offered on site


Infrastructure Changes

Broadband access is not only about plumbing, ie, providing the pipes to carry the traffic, it is about: Applications that generate extra revenue for suppliers New content delivery models

Formation of partnerships between website owners and content delivery providers

Ability to dynamically create and display information on websites based on the type of connection (narrowband or broadband) or device accessing the information (PC, mobile phone, PDA, or other Internet appliance) without user/customer intervention

Revamping of Web sites to design and format them for the high bandwidth user


Infrastructure Changes (continued)

Entertainment Video on demand partnership between Enron and Blockbuster with

other service providers Video on demand partnership with Intertainer Interactive sports and gaming

Emergence of Peer-to-Peer Networking Napster, Gnutella, Hotline

The creation of a whole new broadband lifestyle


Applications

Voice Over DSL Provides users with 16 extra phone lines

Lines can be added dynamically as the need arises

Multimedia Video conferences, Training, Streaming Video Productions

Entertainment (Music, Games, Movies) Music Downloads (Napster, labels, and record stores) Online Interactive Gaming Video On Demand (Enron/Blockbuster deal)

Sports Programming such as can seen on Quokka.com


Results of IEC/Hellerstein & Associates Broadband Access Survey

Broadband Access Survey taken by Participants at the 2000 DSL ComForum

DSL Focus Group held at the IEC 2000 DSL ComForum Survey Findings

Majority of respondents believed that DSL will not be widely deployed within five years

75% of respondents see DSL as an intermediate bridge to more advanced broadband transmissions technologies.
