  1. How to Achieve Carrier-Grade VoIP Roll-Out with Record Time-to-Market and Low Development Cost Majid Foodeei PhD System Architect/ Technical Marketing mfoodeei@centillium.com Centillium Communications, Inc.

  2. VoIP Reality in the Making • Broadband access offering • Wireless (2G/3G) and WiX and NGN convergence • VoIP, “Triple/Quadruple Play” and other services • Commitments/roll-out by tier 1 & comp. providers • BT, NTT, KDI, AT&T, SBC • ISPs, Skype • Examples of milestones and service roll-out traction • BT vendor select done, Initial live trial/deployment • 30+ million Skype users

  3. Building the Right VoIP Gear: Requirements & Challenges • MUST and SHOULD Requirements and Challenges: • Carrier-grade quality • Scalable • Interoperable • Convergence ready (wireless IMS model & NGN VoIP) • 99.999, fault-tolerant, advanced field/live diagnostics and remote monitoring • Feature rich (codecs, network features)

  4. Building the Right VoIP Gear: Requirements & Challenges (cont.) • VoIP or VoP for Converged Networks • Same HW & SW for VoIP/PSTN, wireless (2G/3G/…), NGN VoP • Network interworking with and without transcoding • Many advanced network processing features: e.g. 3GPP Iu/Nb, lawful interception • Voice enhancement features (acoustic EC, adap. level control, noise suppression) • Remains Top Decision Criteria • Time-to-market • Cost (development, system and maintenance)

  5. Overview of VoIP Development Alternatives • Voice Processor Building Block Alternatives • Using general-purpose DSP and NP + multiple SW • Using advanced SoC (DSP+NP+SW) • Advantages of Advanced SoC • Accelerates hardware & software development • Lowers cost (development, system, and maintenance) • Better scalable application SW and HW • Better meets high-density and low power requirements • How do chip-level variables play into development?

  6. Product Cycle Flow-Chart:From Vendor Selection to Operation Maintenance Given Platform/ Chassis & Board Form Factor Advanced SoC Advantage • High capacity/Low power • Low chip count (Integrated) • Fast development (Months) • Low cost • Very fast development (Integrated SW) • Common API across scales • Shorter system testing (System tested SoC) • Lower cost and easier support Feature set ------ HW Development ------ 1- DSP + NP 2- Aggregation 3- Host (Control & Signaling) 4- Other (Power, Redundancy, etc.) Capacity Target Scalability Board Space Power Budget Integrated? 3rd Party? Or Internal? ---- SW Development ---- 1- DSP + NP SW 2- Aggregation SW/Control 3- Host SW ---- System Testing & QA ---- HW/SW Component Integration -- Field Support/ Maintenance -- Component Fault & Testability

Integrated Advanced SoC and 3G-NGN System Software Suites

  8. In Production VoIP DSP & SoC * Source: Linley Group Report (Sep. 2004) * Still the Status for In Production Chips in Aug-’05 * All vendors have roadmaps (Best in class relationships remain)

  9. Case Examples of System Advanced System, Provided at SoC Level • Lawful interception: Integrated at system-level API • 3G wireless advanced features • Tandem-Free and Transcoder Free (TFO/TrFO) • Transcoder and IP-IP/ATM-IP network interworking • 3GPP User-Plane (Iu and Nb) • TTY/TTD/CTM (Cellular Text Mode) • Hand-off and IP-forking • Remote Diagnostics and steam capture • 128-way conferencing with gameoptions

  10. Case of Time-to-Market & Cost Savings • Case A (GP-DSP) • Large and Lengthy (years) Engineering Effort Required • 10 to 20 HW designers, • Big (~40) DSP design team, • Additional Time for MGCP/SIP, System Test and SQA Additional Time/Cost • Case B (Advanced SoC) • Small Engineering Teams • 2 people HW design team • 2 SW Engineers • 2 System QA • First calls setup in 2 weeks after HW • MGCP/SIP MGW deployed in 6 months • UMTS/CDMA2K GW available in done and available in less than one year • Time-to-Market Advantage: Turnkey, complete system solution, system-level flexible API • Cost: Board/System, Development, & Maintenance
