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.

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.
