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

Conclusion
NGN has implemented and put into service for TRIPLE T Broadband in TT&T Group launched In Upcountry and BMA .
Service Offerings: Maxnet (high speed internet) VoIP services and future multimedia convergent services.
The PSTN network replacement Plan by NGN are settled for TT&T in future plan.
The international gateway for TTT Global net also implemented by NGN.
