IAD Challenges/Summary

• Convergence of IAD and residential gateway • Self install solution- residential/SOHO/teleworker• Distribution of voice services via wireless/HPNA• Integration with existing OSS systems is difficult• Standards activity must play a key role • Migration of CTI will drive service revenue• Teleworker, small business and residential= $$$$$$$$• Traditional IAD (Ethernet, RJ-11 Voice) is limited• IAD must be scaleable and able to evolve with services
