  • NGN Network Element (Cont.)Access Gateway- Allows the connection of subscriber to the packet network.- Converts the traffic flows of analogue signal to packet network..

  • NGN Network Element (Cont.)Trunking Gateway - Allows interworking between TDM telephony network to packet-based network.

  • NGN Network Element (Cont.)Softswitch- Referred to as Call Agent or Media Gateway Controller (MGC) provides the service delivery control within the network via H.248 protocol,sip protocol- Performs signalling gateway functionality for interworking with PSTN N7 signalling network.- Provides connection to Intelligent Network or Applications Server (AS) to offer another services

  • NGN Network Element (Cont.)Applications Server (AS)- Support service execution, e.g. to control call server and NGN special resources (e.g. media server, message server) via these protocol: H.248, SIP, SS7, ENUM, MPLS, BGP etc.
