Introduction
� The BBF has been driving the evolution of Broadband Network Architecture for the last 14 years– this has involved all the major stakeholder in the industry
� BBF Technical Reports and Interoperability Programs are playing a critical role in helping the industry face the new challenges– Choices between options have to be made, solutions have to be
end-to-end and they have to be proven
� Interoperability, manageability and integration in operators environments are key requirements
� BBF is open to all technologies and helps convergence

Motivations for a Multi-Service Architecture - I
� Support for different customer types, markets and
services: residential, retail, business, wholesale, fixed, mobile,
cloud/virtualized services over a common network
architecture
� Simplification of network architecture: an end-to-end
architecture based on IP/MPLS and Ethernet with a well-defined
migration path
� Multi technology Access support: xDSL, Ethernet, GPON,
EPON, FTTdp, Microwave wireless, legacy voice, wavelength
access for business customers, TDM circuits
� Multi-Edge support: the ability to source traffic to a given
subscriber from multiple, different, Service Edges
� Enhanced Scalability: moving IP Edge Nodes closer to
customers allows the connection of more customers to the
aggregation network
6
Motivations for a Multi-Service Architecture - II
� Enhanced availability: use of OAM and an appropriate
control plane for automatic protection and/or restoration
� Seamless connectivity: integration of access,
aggregation and core networks
� Operational enhancements: migration to a converged
packet based access and aggregation network can
improve the end-to-end provisioning process by
minimizing touch points
� Enhanced support for Wholesale services: to meet
regulatory requirements (e.g. Active Line Access) and
support non-vertical business models
� Fixed-Mobile Convergence (FMC): to support a single
handheld device for both fixed and mobile access

Fiber integration in triple play deployments
� Replicate over fiber the multi-services architecture adopted over DSL
� Leverage platforms and processes used in existing deployments
� Ethernet interfaces (U/V/W) similar to TR-101� TR-069 and OMCI are perfectly complementary for
customer device management
External interfaces shall be agnostic to particular access technologies - as much as possible.
Flexibility to support various business models and device types
� PON used in access or aggregation networks� Single Family Units, Single Business Units, Multi
Dwelling Units, Multi Tenant Units…� Ethernet or DSL last drop� ONU and Routing Gateway as separate devices or
integrated into one box
Maximize commonality of architecture to reduce integration costs and guarantee interoperability
OLT-ONU Interoperability
� Allow OLT and ONU to be provided independently– By different vendors– By different operators – Ultimately by end users themselves (retail model)
� Functional cut between PON OLT and ONU specified by BBF TR-156 (G-PON access), TR-167 (G-PON aggregation) and TR-200 (E-PON).
� The BBF.247 certification test plan eliminates OMCI implementation options for supporting TR-156 and TR-167 architectures: creates true multivendor interoperability.
11
TR-156 and TR-200: GPON and EPON access
� The entire PON system performs the role of an Access Node as specified by TR-101– U and V reference points remain unchanged– Aims to integrate seamlessly into broadband service providers’
deployments

Broadband Forum G-PON ONU Certification Program
15
The Broadband Forum G-PON Certification Program
� Industry’s first G-PON certification program, based on test plans developed by the Broadband Forum with support of FSAN and ITU-T– Open to G-PON ONU products with Ethernet interfaces and is based
on the TR-247 test plan – Proves conformance to TR-156 using OMCI as defined in the ITU
G.988, which are the most critical standards for interoperability
� ONUs with other profiles and types of interfaces /features will be addressed in the very near future, along with extensions for XG-PON 1
� ONU/OLT Interoperability Test Plan in development, and the ONU Conformance Certification will be a requirement to participate in the Interoperability test program
16
Why have a Certification Program?
� Internationally respected organization with 17 years of interoperability program excellence
� Service Provider driven test plans/required in global RFPs� Shortens test cycles. Offers single round of universally
recognized tests-decreasing costs� Helps vendors competitively position products globally� Independent standards based certification creates a common
language
� Eases the launch of products and expedites fiber deployments
� Having BBF.247 certified ONUs insures that vendors’ products are easily integrated by any G-PON OLTmanufacturers
