  1. Triple-play Solution Offerings forCable Providers Broadband Access Product Marketing UTStarcom Confidential

  2. Agenda • Business Analysis • Technology Options and Comparison • UTStarcom GEPON Solutions • Case Studies • Conclusion UTStarcom Confidential

  3. The Background • Converging domains of Data, Voice and Video • Telcos foray into the world of Video by embracing IPTV and FTTH Strategies • Cable Companies foray into the domain of Voice and Data using the Cable network as a Data Pipe UTStarcom Confidential

  4. Cable Industry Market Trends • Cable Operators considering FTTH/FTTB for Greenfield deployments • Facing strong competition – Telcos are now offering or plan to offer triple-play service over fiber • DOCSIS 3.0 migration slower than expected • Fiber is perceived as the ultimate access pipe to home • Cable Operators want to increase service penetration • Convert the video-only subscribers to triple-play w/o investing money in upgrading the existing wiring • NG Video distribution • Based on Edge-QAM technology • IPTV may be adopted by select operators • NG Voice • Currently supported using Packet Cable 1.5 standard over DOCSIS • Specialized softswitch gateways are used; Connection to PSTN via v5 trunks • Going forwarded, it will be SIP or MGCP based • Content transport • Using MSTP and RPR devices over carrier-grade Ethernet networks • OSS integration to play a major role in adopting new technologies for existing networks UTStarcom Confidential

  5. Market Data • More 350 million cable subscribers worldwide, 60 million have cable modem (broadband access)  Huge potential for triple play • 54% of world’s broadband cable lines are installed in North America. The region is followed by Western Europe with 18% and Asia-Pacific with 16% Source: Point Topic UTStarcom Confidential

  6. Cable Triple Play – Service Offering • Residential subscribers (Typical service offering) • Provided over Coax cable • High-Speed Internet (HSI) • Offered via cable modem • Up to 6 Mbps downstream / 1 Mbps upstream • Mostly best effort (performance may deteriorate in peak hours as subscription increases) • TV • Analog TV  About 70 channels (no need for STB) • Digital TV via STB  200 or more channels • About 10 HD Channels • Interactive Channel Guide • Near Video on Demand (VoD)  On-demand channels • No time shift  DVRs can be used to record programs • Voice • Offered via cable modem • Provided over IP • Built-in SLAs for voice • No support for lifeline (power failure at home means no service) • Not as reliable as Telco voice • Business Subscribers • Provided over Coax cable • Mostly targeted on SOHO / Small Enterprises • Double play service (Voice and HSI) has more utility for the businesses • Price seems to be the major motivation for switching PC Analog TV Cable Modem Phone Coax Cable (From operator) STB Digital TV (SD, HD) Cable Triple Play Service UTStarcom Confidential

  7. Cable Triple Play – Network Approach Source: • Advanced cable networks based on HFC design • Use of return-path for interactive services such as channel guide, video-on-demand etc. • Traditional networks support both analog and digital TV transmission • No support for interactive services • Data services offered using CableLabs standard DOCSIS • Offered over HFC Network • Protocol between CMTS and Cable modem • DOCSIS 2.0 can support up to 40/30Mbps (DOCSIS 3.0 160/120 Mbps) • Typically one CMTS is shared between 300~500 users PacketCable DOCSIS CableHome Video Headend CM CM CMTS CM CM CM Cable Operator network CMTS CM CM Internet CM CM CMTS CM Soft Switch CM Aggregation Network Access Network Headend CPE Fiber Fiber Coax CMTS O/E CM UTStarcom Confidential

  8. TV Service Relationships with all major studios  Access to contents Rich experience in providing TV service Interactive TV services using return-path in a HFC network Huge customer base Reliable service Data Service Higher data rates than DSL Voice Service Bundled with TV and high-speed data service TV Service No real-time VoD No network PVR Limited interactive services (some operators only offer one-way service) Advanced multimedia services such as online gaming may not be possible Data Service Operators with NO HFC network are not able to offer data services  Many operators are in this category Some operators offering Ethernet over Cat-5, however it has very high OPEX Scalability issue with CMTS for higher bandwidths (20 Mbps or higher)  Demand for higher bandwidth continues to grow Telcos are deploying fiber to the premises  Coax can’t complete with Fiber access No SLA guarantees for business users Voice Service Reliability issues  Not competitive with Telco voice service Operators with NO data network can’t offer voice services Other Multimedia services Not enough dedicated bandwidth Key Challenges for Cable Providers Strengths Challenges UTStarcom Confidential
