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 hightechnology 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.
Is FTTP the answer?
Why FTTP?
Why Now?
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

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.

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 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
