5. Nairobi, Kenya, 30 – 31 July 2010 5 Conformance testing and interoperability (C&I) in transport layer Most expensive layer in man-hours spend (OPEX) for the network operator Where C&I will have a major impact for network operators, in particular, in the developing countries A global C&I program will contribute towards minimising the Total Cost of Ownership (TCO) for the network operator

10. Nairobi, Kenya, 30 – 31 July 2010 10 Conformance testing and interoperability (C&I) in session control layer Many SDO/Fora C&I activities, which does not assist the network operator Need to have agreement between the SDO/Fora industries to work towards one globally acceptable C&I program Certainly will contribute towards more efficient network operator businesses and more cost effective and affordable telecoms/ICT products and services

17. Nairobi, Kenya, 30 – 31 July 2010 17 Conformance testing and interoperability (C&I) in support systems layer Major cost factor for the network operators from a TCO perspective A global C&I program that integrates the Telco, IT and Web domains is required Requirement is for managed end-to- end products and services in a multi- technology, multi-vendor equipment, multi support systems environment

19. Nairobi, Kenya, 30 – 31 July 2010 19 A recommended step-by-step C&I implementation strategy Step 1: There are many C&I industry role players… utilise what has been developed, do not duplicate, but agree to work together Step 2: Network operators need to satisfy customer requirements from an end-to-end perspective – adopt and deploy one integrated globally certified C&I process and program
