August 8-10, 2006 Santa Clara, California Hyatt Regency Santa Clara Hybrid Networks Today Corporations will continue to use TDM infrastructure. Hybrid networks with both TDM and VoIP access are a must to keep cost down. DSP resources and HMP should become a mainstream technique for handling large amounts of VoIP traffic, connections.

August 8-10, 2006 Santa Clara, California Hyatt Regency Santa Clara Building HMP Systems Need a high level SDK with open standards support. Ability to code application once and work across entire product line. Access to Management interface A rich set of tracing tools for troubleshooting Samples

August 8-10, 2006 Santa Clara, California Hyatt Regency Santa Clara What tools and protocol support is needed? SDK’s supporting high level programming languages such as - C#, Visual Basic,.NET, VB Script, C and C++. Support for the VXML Standards – MSS, Envox, Nuance VoIP protocol support SIP and legacy H.323 applications. Audio compression and call transfer protocol support

August 8-10, 2006 Santa Clara, California Hyatt Regency Santa Clara Real Time issues to face: TDM only – Business moving to VoIP HMP only systems may not have enough processing power for 400+ sustained calls at the same time in one box. Depending on Protocols used. – g.711, g.729. Hybrid server with TDM and HMP in same server is cost effective, but how many calls can be handled in a single enterprise server?

August 8-10, 2006 Santa Clara, California Hyatt Regency Santa Clara Real time answers: Voice and Video Communications require real- time processing –HMP seems to work well in small office environments and branch offices –Large enterprise systems need more horse power to handle the demands of echo cancellation, VAD, CNG, DTMF Clamping, etc. Box solution with dedicated hardware may be required Resource DSP boards may be required

August 8-10, 2006 Santa Clara, California Hyatt Regency Santa Clara HMP-Only Concerns: What is the number of real time sessions I can run? How many G.729 compressed calls are we able to make? Will my HMP solution be able to support video in the future? Will my application have enough processing power left for my voice/speech applications?

August 8-10, 2006 Santa Clara, California Hyatt Regency Santa Clara Why DSP Acceleration for VoIP Communications? Scalability –Enterprise to 600 resources per board –4 boards per system –Powering for 2400 concurrent sessions Predictable performance –HMP is a shared architecture – can be unstable at top end –DSP resources are dedicated to the task Able to deal with new and CPU intensive voice and video codecs Lastly, plenty of CPU resources available for the application Question: So, how are you going to support 1000 to 2000 sessions in a single PC server?
