(Next Generation Network) system architecture. IP DSLAM (IP based DSL Access Multiplexer) to
fast extend the coverage of xDSL services and to facilitate DSL deployment.
IVD is a remote type IP based VoIP Gateway provides toll quality voice communication in terms of
voice quality and reliability for the user. The type of service and application scenario is supported
