  1. Next Generation Networks – delivering competitive advantage Neil McArthur Chairman, TalkTalk Technology

  2. Agenda • What’s an NGN • Our NGN • The significance of Ethernet • The importance of QoS • Opals Network based SIP development • Managing Legacy to NGN migration • Assurance.

  3. What is an NGN? Network intelligence Applications Conveyance • Multi-service network • QoS enabled • End to end IP based network • Separation of conveyance and service control (network intelligence) functions/applications • Ability to build new services without changing the network infrastructure • NGNs speed up innovation

  6. What does our NGN look like? • Core network two 400 Gig fibre rings around the main population centres. 47 core POPs • 800 Gig Supercore fibre network around greater London taking in all the Telehouses and main carriers • Layer 1 & 2, access network building to 2000 exchanges • Exchange MSANs copper and fibre, supporting Residential, SOHO and SME services • Hierarchical QoS enabled network hence supporting voice and data services

  7. Index DWDM Nodes (Optical connectors) Collector Nodes Unbundled Exchanges Core Network 800Gb 400Gb 10Gb Covers over 80% of businesses – 2.1 million business premises Commitment to increase to 2,000 exchanges for both MPF and SMPF by end 2010 85% coverage of businesses Ethernet termination at 1,300 exchanges in 2010 Fig 3

  10. Impact of Ethernet Source: Analysis Research, 2007

  11. The significance of Ethernet • Has become the established standard for network interconnectivity, at work and in the home • A disruptive technology, replacing Frame Relay, ATM, E1,Token ring etc • Can be delivered cost effectively across large scale NGNs • Not distance dependant and highly scalable • End to end standards based, meaning compatibility • Creates another telecoms inflection point

  12. Three phases of Carrier Ethernet • E-LAN, E-Line, E-Tree services • P2P, P2MP, MP2MP Metro and national Ethernet Layer 2 • Access circuits to MPLS • 10/100/1000Mbps fibre access, with resilience options • Incremental, flexible service bandwidths/internet over Ethernet option • Aim to be MEF 9 and 14 compliant Phase 1 Phase 2 Standard Ethernet Enhanced Ethernet • EOAM 802.1ah - end to end QoS management and reporting • Remote diagnostics capability, enhanced alarm functionality resulting in better SLA, reduced downtime, greater visibility of service performance • Bandwidth profiling • Burstable bandwidth option Phase 3 EFM/NGAEthernet over copper • 3Mbps-40Mbps service bandwidths over copper • To be included in Ethernet and MPLS services • Option for a lower-cost alternative / different SLA

  13. Tactical and Strategic Ethernet

  14. QoS enabled network • QoS is the differentiator on NGN service delivery. • Network supports Hierarchical QoS in the core, edge and access • QoS Protocols - MPLS, COS, DiffServ • Precision Time Protocols. IEEE 1588v2 • Layer 2 Ethernet OAM, ITU 1731 • Layer 3 IPSLA

  15. Opal’s SIP development • Our NGN already carries 1.5Billion minutes of VoIP traffic month • So where are the network based SIP products? • Connectivity is key in the SIP business • Functionality around In/ Outbound • Centrex- Featureline services • IVR services • Number portability

  16. Voice Solution Overview • Access to suit customer requirements • Customer has transport choice • Network Hosted Features as standard • Up Sell to Network Value Adds

  17. Managing TDM to NGN migration • Leave the choice to the customer. • Our view is we should accept voice traffic into the NGN either as TDM or IP. For both PSTN and ISDN. • Customers migrating to IP PBX may send traffic direct as IP over DSL or Ethernet. • Customers retaining TDM PBX may send traffic to the NGN over Ethernet using Circuit Emulation. • Traffic is carried into the core of the NGN and broken out into conventional TDM trunk exchanges. • This avoids building out TDM/SDH network out to exchanges.

  18. No 1 in Copper Assurance • Investment of over £5M on copper loop testing • Openreach accept our fault data • Proactive fault management • Fastest average speeds over copper in the UK • Dynamic line management DLM optimises copper line speeds • Important in EFM deployment.

  19. Ethernet OAM Enables engineered SLA’s at Layer 3 and above by delivering Layer 2 fault and performance management End to end functionality validated through implementation of industry standards 802.1ag – Connectivity Fault Management (CFM) ITU T.Y.1731 – Service Performance • Key OAM Metrics reported on: • Availability • Throughput (% of CIR/EIR) • Frame Loss • Frame Delay • Frame Delay Variation

  20. Our vision What does our NGN offer our partners? • Separate service from conveyance • Allowing Partners more space to add value • Moving to access based charging • Unify B2B connectivity towards Ethernet. • Roadmap of migration from legacy to NGN operation • Network SIP product set in development. • Better transparency of assurance
