13 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..
14 NGN Network Element (Cont.) Trunking Gateway- Allows interworking between TDM telephony network topacket-based network.
15 NGN Network Element (Cont.) Softswitch- Referred to as Call Agent or Media Gateway Controller (MGC)provides the service delivery control within the network viaH.248 protocol,sip protocol- Performs signalling gateway functionality for interworking withPSTN N7 signalling network.- Provides connection to Intelligent Network or ApplicationsServer (AS) to offer another services
16 NGN Network Element (Cont.) Applications Server (AS)- Support service execution, e.g. to control call server andNGN special resources (e.g. media server, message server)via these protocol: H.248, SIP, SS7, ENUM, MPLS,BGP etc.
