Projected PON Deployment

The Need for Interoperability TestingService providers increasingly employ multi-vendor strategies in the access

Allows best-of-breed selection, resiliency against roadmaps and changes in pricing modelsCommon in DSL, 1:1 fiberNew in PON – traditionally single-vendor infrastructures, not feasible for 2nd generation deployment -- ONT and OLT need to become multi-vendor interoperable

Triple play services require deep dive in interoperability testing for service quality Regulators require uniform, standards-based interfaces in some countriesCross-technology interop required on management layer when mixing access technologies like PON, DSL and EFM

Interoperability Scenarios

Access Interoperability Testing at EANTC

MPLS and Ethernet World Congress, Feb 2009Carrier Ethernet World Congress, Sept 2008

Ethernet OAM Interoperability

Focused on business services (1:1 fiber, FTTB/FTTH) so far12 router/switch plus 2 analyzer vendors participatedOutstanding level of support Implementations fully interoperable for the three basic services (CC, LT, LB)Added Remote Defect Indication tests

Mobile Backhaul Interoperability Requirements

Additional network services required:Clock synchronization – rapidly growing number of implementations for IEEE 1588v2TDM (E1) over packet – established marketATM over packet – established, small market with some functional interoperability issuesSynchronous Ethernet – rare, early implementations… and, of course, Quality of Service and high availability functions

Future PON Multi-vendor Interoperability Test Areas

Multicast, including service separationDownstream encryption G.984.4 Management entitiesDynamic Bandwidth allocation (DBA)OAM across PON, DSL and EFM technologies

SummaryIncreasingly complex FTTx design frameworks

Multiple services: Triple Play, Business, MobileBackhaulMultiple access technologiesAutomated management and control

Physical layer testing is matureLots of things to do for network, transport,application testing of FTTx architectures
