The Future of DSL
A Telecommunications and Technology Research Group“Give Your Company the Competitive Edge”
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 (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
A Telecommunications and Technology Research Group“Give Your Company the Competitive Edge”
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
A Telecommunications and Technology Research Group“Give Your Company the Competitive Edge”
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

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.
