Service definition

Service definition has been provided by the operator groupThree service category :

TV based servicesPC based servicesVoice services

D9 - 09/04/2002


System Architecture and CPE

A specific terminology has been introduced to avoid confusion between modem, gateways, residential gateways ….

The SA and CPE group has definedEnd-to-end protocols to support basic connectivity and basic functionThe use of an hybrid modem performing both L2 and L3 functionsCPE and network behaviors to support access to several IP networks

Main choicesUse of ATM as layer 2 over DSLCore network flexibilityDistributed and centralized environment for the CPEConsideration of an « Ethernet-like » home network

No selection of an home network technologyTransport of the video is coding-independent

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

play services

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
