FMC Solution Advantage – Service Provider Perspective Converged service infrastructure by consolidating the voice services between the fixed and mobile networks Mobile coverage (GSM, CDMA) – Offering mobility, convenience and ubiquity Wi-Fi SIP over broadband – Offer better quality, lower cost and feature rich capabilities Enhancement of Service Quality Stimulates the new service opportunities to increase ARPU Capability to quickly include value added services - VMS, SMS, CRBT, FMFM, Centrex. . Provides the service differentiators and creates the service stickiness to lower the churn rate Reduction in CAPEX/OPEX by offloading the traffic from cellular to WLAN and spending less on infrastructure buildout Single set of user credentials Using GSM IMSI method authentication for both networks simplifying the user management System Reliability and Scalability backed by Real Deployment Based on the proven NGN (m. Switch) platform (and its IP core) The single m. Switch solution implementation serves over 2. 1 m subscribers Architecture compliant with 3 G/IMS Future-proof via open standards Colombo, Sri Lanka, 7 -10 April 2009 3
FMC Solution Advantage. User Perspective FMC enable users to access their voice and data services transparently, regardless of their location, device, or network-access method ‘One Number’ and ‘One Phone’ service Wi. Fi SIP or GSM/CDMA coverage The user will be able to initiate and terminate calls at any place Seamless Roaming The user will have non-interrupted call sessions when moving from one network to another Uniform and consistent service accessibility & behavior independent of access especially attractive for enterprise users to extend corporate VPN to cellular networks. Reduced monthly charges & convenience of a single bill Simplified and Unified service plans and payment schemes. A single always reachable phone number (Option for dual number) Availability of new services e. g. IM, Unified VM, SMS, Unified phone book, CRBT…. Colombo, Sri Lanka, 7 -10 April 2009 4

No Impact to Existing Networks To Existing NGN Networks: A functional module addition to the existing Soft. Switch and backend application Able to use the existing NGN for call processing and routing Normal NGN users are still served by existing infrastructure Zero impact of the FS addition All (home/visiting) FMC users will be served by the FMC-FS Registration, authentication, roaming, call processing, handover FMC-FS requires access to FMC user profile data HSS (Home Subscriber Server) model of IMS To Existing GSM Networks: GSM Homed FMC users appear to be regular GSM users NGN Homed FMC users appear to be visiting GSM users FMC-FS uses standard roaming Interface to the GSM Network Colombo, Sri Lanka, 7 -10 April 2009 6

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 10
UTStarcom Solution PSTN Emulation Subsystem – PES Provide services to green-field customers Replace the existing TDM switch – total 7 models in place m. Switch as the core Soft. Switch + Gateways + Backend office applications i. AN 8000 as the access Combination of DSL, DLC and Vo. IP AG Foundation for FMC and IPTV in the future Phase 1: Started with 150 K NGN lines capacity Network installation and migration planning for 3 months First TDM switch replacement/migration in March 2006 Adding customer via both old switch migration and green field expansion Service extension to Centrex Targeting under served enterprise customers Phase 2: Network expansion to total of 500 K NGN lines Contract signed in later 2006 Network fully deployed Phase 3: Planning for total of 1. 5 M NGN lines in 2008 Total 5 m NGN lines planned in next 3 – 5 years 150+ CO sites replaced by 3 NGN SS sites Colombo, Sri Lanka, 7 -10 April 2009 11
Migration Benefits CAPEX Savings Central Office (CO) consolidation Simpler network with fewer types and pieces of equipment OPEX Cost Savings- 80% Operation and Maintenance cost reduction Reduced power consumption- 94% (Reduced air-conditioning requirements) Faster provisioning of services Floor Space Savings- 92% Reduced space requirements Consolidation of cabinet areas Improvement in “time-to-market” for new services- 90% Faster introduction of new services Increase in Revenues EOL management End of support to critical TDM components- High cost of vendor support Stop manufacturing of components Salvage components to support in-house repair of modules when they run out of spares.
