  2. Continued top line growth despite industry boom/bust • Participate “Other” = ATM, Leased Line, VPNs… “Mobile = Fixed in 2003 by customers • Manage costs • Innovate Migration to mobile Dial IP to broadband Regulatory moves Why transform?Service revenue trends Global telecom services revenues 1400 Other Mobile 1200 Fixed telephony 1000 $bn per annum 800 600 400 200 0 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2007 2006

  3. Why transform?To improve the operators’ business case • Increase Sales through New Services • Networks must enable new services • Coming up with ideas like text messaging, the Internet or iTunes is hard • Difficult to justify the business case • Optimise CAPEX • Deploy modular, multi-functional, scaleable & flexible platforms • True multiservice equipment supports longer write down periods • Save OPEX • Consolidate multiple network stovepipes • Cut per-stovepipe Opex • Build a simplified multiservice network • savings can be calculated

  4. Past Future Why transform?Network traffic is changing Connection-Less Packet Services e.g. SMDS, IP, IP-VPNs 100% 100% Connection- Oriented Circuit Services e.g. PSTN & SDH ?% 0% 0% Connection-Oriented Packet Services e,.g. X.25, Frame Relay, ATM & MPLS

  5. Stovepipes - Today Each Stovepipe has different • Staff • Service processes • Network management • Network equipment • Spares • Training • Purchasing processes • Write down periods Management Core Regional Routing Access Frame Relay PSTN IP X.25 RAN LL ???

  6. The Dream - Converged Network To be realistic there are some issues: • Needs organisational change • Need to “spend to save” • Some say, “the old networks served us well” • they help manage complexity Management Core Regional Routing But we think operators need to take action • the status quo is not an option • fixed network revenues under pressure • technology now has the scale required • consider rationalising legacy services Access Frame Relay PSTN IP X.25 RAN LL ???

  7. Properties of a Transformed Network • Services • Rapid service deployment • Support for fast feature churn • Customer self provisioning • Support for user mobility • Greater security • Managed support for legacy services • Costs • Lower opex • Fewer sites • Fewer equipment types • Common spares • Fewer processes • Technology • Convergence on IP • High availability • Stability • Scalability

  8. When to Transform? • New operators are doing it now • No legacies to accommodate • Fixed line operator revenues are under pressure • Need to start convergence whilst there are sales to support transformation • i.e. before obsolescence starts to hurt • Mobile operators need to respond to converged operators • with fixed/mobile services • and new types of mobile services over new access types e.g. WiFi and WiMAX • Network age • Position on the investment cycle • But still need to plan

  10. Edge Multi-Service Access Regional / Metro Gateway POPs TDM Gateways NB PSTN fixed & mobile Session Border Controller VoIP/Data Networks Service Platforms Meshed MPLS Core Network • Server Platforms e.g. • IP Services Router, • Bandwidth Manager, • SoftSwitch Call Agent, • Provisioning Agents, • Intelligence The Very High Level View • VoIP / TDM gateways • with local aggregation • Media Gateways • Signalling Gateways • Primary rate access • Meshed, • Multi-service • MPLS devices • connected by • core transport • (physical or • logical, sized • appropriately) • BXR-48000 • Single Access Platform type • for Fibre, Radio, xDSL • PSTN & Private Circuits • SDH • Access Hub • Access Radio • Fire-walling, Policing • & Address Translation • Session BorderController

  12. Some more points • Network evolution is a challenge for operators • Each operator will start evolution for different reasons • Each evolution decision should be towards a vision of a low opex, multi-service network • The industry has long talked about convergence on multi-service platforms • The conditions are now right for this to happen • Marconi understands networks and has the ‘transformation products’ • Access Hub • SoftSwitch • IN • BXR-5000, BXR-48000 • SDH, WDM and radio transport products

  13. Next Generation Network Examples Frédéric Auger Business Development December 2004

  14. Today 1,000+ Voice Switches & Data Cross connects 80,000 PCP in the access network 100,000 DSLAM, Concs & Data multiplexers 170 Core Switches The Future Begin fibre roll-out to the PCP 100 Metro routers 10 Core routers 30,000 MSAN Example of NGN Structure Vision Multiple Service Management Organisations & Systems Multiple Aggregation Devices International networks Simpler Service Management Data Centre Source : BT, Marconi Fewer Devices - increases network reliability

  15. PSTN Migration • Marconi ideally placed to develop the interworking with SIP for carrier networks from: • track record in delivering PSTN features, • expertise in building large and resilient networks, • focussed on organic migration, making the best of existing assets • Marconi shape and adhere to industry standards, in order to create an open infrastructure

  16. M U L T I M E D I A Future Voice Will Be Supported on MSANs & Switched by SoftSwitches Service Execution Function Intelligence PSTN Combo Call Servers Broadband TA Modem Metro Node DSL MPLSCORE Router TDM to OLOs TDM to NGS IP to OLOs Media server Gateway Business Data NTE Multi ServiceAccess Node (30,000) Metro Node (100 - 120) Core (10)
