NGN Concept NGN is a concept for defining & deploying networks, which due to their formal separation into different layers & planes and use of open interfaces, offers service providers a platform which can evolve in a step -by-step manner to create, deploy & manage innovative services. NG Architecture : Service oriented, layered (transport, control, application) NG Services : mobility) Converged (quad play- voice, data, video & NG Access : High speed (Broadband) IP based connectivity (ADSL, VDSL, Wi. Max, Cable TV, FTTH) NG Transport : NG Mobile 3 G+, 4 G : Ethernet, IP-MPLS, RPR, T-MPLS NG Internet : IPv 6 NG Interconnect : Capacity and Quality based NG Licensing : Unified, Converged Colombo, Sri Lanka, 7 -10 April 2009 5

FMC-Business Drivers Many households today have at least one cell phone. In these households estimated 60% of long distance calls and 36% of local calls take place on mobile phone at home (Yankee Group) 14% of users use cell phones as their primary line (Yankee Group) Additional 26% of users are ready to switch as in-building coverage improves Over 50% of users place mobile calls when they are at home or office (Wireless Review) Wi. Fi exists or can be supported in both places Traffic on mobile network has been increasing causing Qo. S problem and hence subscribers’ churn Pressure to reduce tariff for voice services “Fixed” broadband availability is growing at a rapid pace - double digits in CALL most cases FAILED Vo. BB provides new revenue stream for Service Provider, and also give a low cost alternative to carry mobile voice traffic Leverage low fixed line asset cost to support the mobile voice application PLEASE TRY AGAIN! Users need to access services seamlessly regardless of their location, active device or the network access method Lower CAPEX, Lower OPEX, Higher coverage and quality Colombo, Sri Lanka, 7 -10 April 2009 11
Driving Forces Consumers like mobile phones And all of them are not using just for mobility In >50% cases used for portability, not mobility. Consumes demands low cost for voice Broadband is getting widely deployed Voice over broadband is not only new revenue stream for SP, but also the low cost alternative to carry mobile voice traffic Leverage low fixed line asset cost to provide the mobile voice application Lower CAPEX, Lower OPEX, Higher coverage and quality => Fix Mobility Convergence Colombo, Sri Lanka, 7 -10 April 2009 12

Solution fit for different Operators MNO (e. g. Cingular, Sprint) Improve the mobile coverage with low cost Wi. Fi- Residential / Enterprise / Public hotspot Partner with Cable/Fixed Op to offer total package- Triple or Quadra-play NGN Operator (e. g. Vonage) Enhance their current offerings with mobile capability Partner with MNO as whole sell (MVNO) or roaming Integrated Service Provider (e. g. Brazil Telecom) In-house Mobile and Fixed line operation FMC allows them to use fixed line infrastructure to offer mobile service The combined infrastructure provides lower OPEX ratio comparing with pure MNO Cable Operators (e. g. GCI, Comcast) Partner with MNO to offer FMC Natural extension from Triple-play to Quadra-play – Voice, Data, TV/Video, Mobile FMC-Enabler (e. g. Veri. Sign) Host equipment and provide FMC backend capability to other NGN, MNO operators Work with multiple small/tier 2/3 operators – Don’t acquire FMC subs directly Colombo, Sri Lanka, 7 -10 April 2009 15

PSTN to NGN Migration Case Study Background A leading tier 1 carrier in Philippine Owning 2 m fixed & 22 m GSM mobile customers as of Q 2 2006 A public company listed in NYSE Total market cap of US$7. 8 B as of Sept 2006 Total revenue US$2. 5 B in last 4 quarters EBITDA US$1. 6 B in last 4 quarters Operating margin 37% A fast growing service provider in Asia Provides fixed line, GSM mobile and broadband data service to both residential and enterprise customers Problem Statement How to sustain and grow the fixed line service? Lots of population without telephone service Lots of business users demand more service How to increase the ARPU leveraging NGN/IMS? IPTV? FMC? Triple-play? Quadrupled-Play? How to lower the OPEX? Real estate expense in the big metropolitan area? Power consumption? Human resource required for operation? How to manage EOL/EOS of the aged TDM switches? The cost of maintaining is unbalance with the cost of buying new Colombo, Sri Lanka, 7 -10 April 2009 21
