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

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

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

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

 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
