Conclusion
There is not only one definition of triple playThe exact set of service will differ from one country to anotherH610 defines a set of functions and tools to help the setup of triple

H610 is Video centricConsidering DSL technologies, mobile network are out of the scope
Service interactions are not considered in detailSG16/QB plans to investigate in this direction
