The Importance of the Management Plane for FTTP
A Perspective of a USA Service Provider
The Telecom Industry is Changing
Last Year Marked a significant Change in the Telecommunications Industry in the USATraditional Wireline companies saw a loss in overall access lines, despite an overall gain in Homes PassedThe oldest telecommunications company in the world, left telecom as a technology and evolved to merge with Cable as a transportUsers appetite for bandwidth is acceleratingMOBILITY HAS BECOME THE PARADIGM
A USA Perspective
160 Million Americans have Mobile Phones24 Million have 1st Generation Broadband connectionWireless Networks are allowing Broadband on the GoPicture/Camera Phones outsold every other phone type in the USA
Broadband + Mobility
=
Transformation
Goal in the Industry
Goal is to deliver 100Mbs capacity to the customer, no matter where they are, at home, at work, or on the go.
Where do we get there from here?
Reinventing our networks around broadband, packet and Voice over IP technologies
Vision is of an integrated Multi-megabit network that will fuel the growth of high-technology industry
Some Statistics
46 Million of our telephone lines are equipped for DSLMore than 36 Million people each day use Verizon WirelessServe over 7 Million Small Businesses and over 80% of the Fortune 1000Over 100 Million people uses Verizon Networks every dayCurrently support over 2 Billion Peer-to-Peer connections every day
Key to survival in a transitioning market
Deploy leading edge technology
High on the bandwidth chain
Good Service
Great Value Proposition
What is FTTP?
Fiber To The “x” (FTTx, with x being the “C” for the Curb, or “P” for to the premises) is an important, emerging technology that will provide customers with new feature-rich services and improved quality of current services.
Why FTTP?
Why Now?
Is FTTP the answer?
Why FTTP? Consumers will require additional bandwidth to the home in the near futureCompetition is beginning to offer a “triple-play” (i.e., voice, video, and data) bundleFTTP provides SPs with the ability to provide “cutting edge” technology and “best-in-class” services Deploying a fiber optic cable to each premises will provide an extraordinary amount of bandwidth for future servicesAn FTTP based network will result in less operational expenses

Today's applications are continuing to drive demand for increased bandwidth
Historically, unforeseen applications have quickly consumed available bandwidth and driven the development of higher speed platforms
FTTP has the necessary bandwidth to support near term
and long term services
FTTP has the necessary bandwidth to support near term
and long term services
Why Now? (Cont’d)
SPs are losing access linesBundling with the triple-play should reduce the churn
Competition with cable providers is forcing actionCable Modems currently have over 60% of the HSD market share and the gap is expected to increaseCable companies are beginning to offer voice over cable A number of IP telephony trials are currently underway:
Time Warner in Portland, ME Comcast in Coatesville, PA Cablevision in LI / NJ
Experience suggests that cable will be very successful, absent an effective competitive response.
Matching Application and Network Requirements
High Speed Internet Access (browsing, IM, Chat, FTP, VPN, access, etc)

Data Application Typical bandwidth (downstream)
Deployment of FTTH
Plan is to reach 1 Million Homes by end of 2004 in the 20Mb to 30Mb rate
Double that rate as we move into 2005
Reach 100Mb by 2007

FTTP BasicsFull Service Access Network (FSAN) – Primary source of PON standards. Created by service providers in order to facilitate suitable standards. FSAN Standards – ITU-T G.983Passive Optical Network (PON) – a point-to-multipoint local access Network.Optical Line Terminal (OLT) – active component typically located in the central office.Passive Optical Splitter – distributes optical signal from a single fiber to multiple fibers, merges signals from all fibers, & connects them to the OLT receiver.Optical Network Terminal (ONT) – housed in a network interface device enclosure.

Standards will drive the speed with which newer technologies
can be delivered
So what areas do these new standards need to cover?
A brief look at a Verizon answer to that Question
Iobi and Verizon-one
How do we create this new set of Service Management
Standards?Rethink the applicability of our current B2B models for SP to SP operations
Begin aggressively the development of C2B interfaces by Focusing on requirements Evaluate the applicability of current standards
Understand the Value Proposition of standards in this area
Additional Considerations
Home Network Selection is currently ill defined in terms of a practical solution to support all data types
Current Home Gateways do not offer the security needed to support the multi-SAP models
QoS models and requirements are not defined for all Home Networks or Gateways
