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
o BT, NTT, KDI, AT&T, SBC o ISPs, Skype
• Examples of milestones and service roll-out tractiono BT vendor select done, Initial live
trial/deploymento 30+ million Skype users

Building the Right VoIP Gear: Requirements & Challenges
• MUST and SHOULD Requirements and Challenges:o Carrier-grade qualityo Scalable o Interoperableo Convergence ready (wireless IMS model & NGN
VoIP)o 99.999, fault-tolerant, advanced field/live
diagnostics and remote monitoringo Feature rich (codecs, network features)
M. Foodeei, Centillium Comm.
Building the Right VoIP Gear: Requirements & Challenges (cont.)
• VoIP or VoP for Converged Networkso Same HW & SW for VoIP/PSTN, wireless (2G/3G/…), NGN
VoPo Network interworking with and without transcodingo Many advanced network processing features: e.g. 3GPP
Iu/Nb, lawful interceptiono Voice enhancement features (acoustic EC, adap. level
control, noise suppression)• Remains Top Decision Criteria
o Time-to-marketo Cost (development, system and maintenance)
M. Foodeei, Centillium Comm.
Overview of VoIP Development Alternatives
• Voice Processor Building Block Alternativeso Using general-purpose DSP and NP + multiple SW o Using advanced SoC (DSP+NP+SW)
• Advantages of Advanced SoC o Accelerates hardware & software development o Lowers cost (development, system, and maintenance) o Better scalable application SW and HWo Better meets high-density and low power requirements
• How do chip-level variables play into development?

Scalability
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

Case Examples of System Advanced System, Provided at SoC Level
• Lawful interception: Integrated at system-level API • 3G wireless advanced features
o Tandem-Free and Transcoder Free (TFO/TrFO)o Transcoder and IP-IP/ATM-IP network interworkingo 3GPP User-Plane (Iu and Nb)o TTY/TTD/CTM (Cellular Text Mode)o Hand-off and IP-forking
• Remote Diagnostics and steam capture• 128-way conferencing with game options
M. Foodeei, Centillium Comm.
Case of Time-to-Market & Cost Savings
• Case A (GP-DSP) o Large and Lengthy (years) Engineering Effort Required
• 10 to 20 HW designers, • Big (~40) DSP design team,
o Additional Time for MGCP/SIP, System Test and SQA Additional Time/Cost• Case B (Advanced SoC)
o Small Engineering Teams• 2 people HW design team• 2 SW Engineers• 2 System QA
o First calls setup in 2 weeks after HW o MGCP/SIP MGW deployed in 6 monthso 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
