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 USA • Traditional Wireline companies saw a loss in overall access lines, despite an overall gain in Homes Passed • The oldest telecommunications company in the world, left telecom as a technology and evolved to merge with Cable as a transport • Users appetite for bandwidth is accelerating • MOBILITY HAS BECOME THE PARADIGM
A USA Perspective • 160 Million Americans have Mobile Phones • 24 Million have 1st Generation Broadband connection • Wireless Networks are allowing Broadband on the Go • Picture/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 DSL • More than 36 Million people each day use Verizon Wireless • Serve over 7 Million Small Businesses and over 80% of the Fortune 1000 • Over 100 Million people uses Verizon Networks every day • Currently 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 future • Competition is beginning to offer a “triple-play” (i.e., voice, video, and data) bundle • FTTP 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 services • An FTTP based network will result in less operational expenses
100M 12 - 50M Access Bandwidth Growth 12 – 25M 1.5M – 3M 256K – 1.5M 144K 2.4 – 56K VDSL Cable Modem ADSL2(+) ADSL DDS 1970’s ISDN FTTP 2004 Why FTTP? (Cont’d) FTTP has the necessary bandwidth to support near term and long term services • 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
Why Now? (Cont’d) • SPs are losing access lines • Bundling with the triple-play should reduce the churn • Competition with cable providers is forcing action • Cable Modems currently have over 60% of the HSD market share and the gap is expected to increase • Cable 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.

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 Basics • Full Service Access Network (FSAN) – Primary source of PON standards. Created by service providers in order to facilitate suitable standards. • FSAN Standards – ITU-T G.983 • Passive 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.

SO, What is missing? • No Standards currently exist for the Service Management or Network Management of Co-merged networks
What is Needed? • Requirements for Service Management • Common Protocol-neutral models of these interfaces • Common agreed upon Protocols to support the Service and Network Management Interfaces

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
