(Cont) Short Term objective: Create New Revenue possibilities Removal of boundaries between voice and data opens the way to new kind of services Can be realized relatively quickly with limited investments Long Term objective: Realize Cost Savings Simpler network More efficient network Cheaper network components Full benefit only realized when all separate networks have fully migrated towards the target solution 4 6

4 . architecture (Cntd) A public packet-based communications network with the following characteristics: layered architecture Layers can evolve independently open interfaces between the layers and all other networks Best in class for each layer seamless control of multiple transport technologies Cost savings due to focused CAPEX and reduced OPEX Centralized intelligence Fast and efficient introduction of new services Gateway interconnection far simpler than Exchange interconnection New services new revenues 7.

Key Features efinition & Features of efinition of (raft Rec. Y.00) A is a packet-based network able to provide telecommunication services and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies. It offers unrestricted access by users to different service providers. It supports generalized mobility which will allow consistent and ubiquitous provision of services to users. Target Standards Area Generalized Mobility Unrestricted Separation Services with Transport QoS-enabled Transport Multiple-Broadband Convergence btw.
