  1. The Changing Role of DSPs in Media Gateway Design James Awad – Product Manager Octasic Inc.

  2. What is a media gateway (MGW)? IP Network Mobile Platform IMS GW IP/DLC TDM Network DLC Access Platform IAD

  3. What is a MGW DSP? Circa 1990 Today Memory I/F Memory I/F Eth TDM CPU CPU CPU CPU CPU CPU Ext I/F CPU CPU CPU CPU CPU CPU CPU CPU CPU CPU CPU CPU CPU

  4. State of the MGW Market VoIP adoption

  5. State of the MGW Market No one likes a mature market! • Little to no growth • No innovation • Very high cost pressure Who is providing growth and innovation? • Session border controllers (packet to packet) • Wideband codecs for IP and mobile communication • Advanced services such as video • What’s next?

  6. Designer’s dilemma… “I need to design a cost-effective MGW today so that I can evolve quickly to support tomorrow’s features”

  7. Ideal solution – Software licensing Use key files to enable features or capacity Similar to well-known FlexLM™ FPGA companies have started providing similar firmware locking capability Hardware and software vendor must be the same • Hardware assisted key management

  8. Sales process Fixed Solution Product 192 Channels Features a,b,c,d,e Product Requirements100 ChannelsFeatures a,b,c Licensed Performance for Field Upgrades More channelsMore features Software Licensing100 ChannelsFeatures a,b,c

  9. Product A Vocallo License A Product B Vocallo License B Product C Vocallo License C One design – Many products Low channel capacity Single HW/SW Design Investment Larger feature set Vocallo Higher channel capacity

  10. Contract Manufacturer Product A Capacity: 100 Ch.Features: a,b,c SW License Further cost savings Purchase Order

  11. Summary Market maturity has created immense price pressure Media gateway designers want: • Cost effective solutions ASAP • Differentiated solutions that can be activated on demand Software licensing offers the best of both worlds • Low entry cost • Feature & Capacity upgrades through software keys
