There have been various emerging trends in the deployment of telecom networks recently. Due to liberalization and technological advancements a common core network for voice and data based on MPLS has been implemented by Telecom service providers. By offering a variety of data and multimedia services, the revenue generating process can also be maximized. The economic and regulation trends also have to be synchronized for the proper and step by step replacement of traditional network by NGN. The current flow is to provide users with multitude of services thus meeting their high demands and enhancing revenues for network operators. Class 5 and Class 4 are our legacy circuit switches based upon TDM to transport voice. For handling control functions, call setup and teardown SS7 signaling was used. The traditional network was designed to support voice services only not being able to meet customers’ demands who require a variety of services at an optimum cost. The aim of this work is to present the role of NGN encompassing the telecom network, architecture and technologies. Also it has emerged as a new platform to decrease the CAPEX and OPEX of overall network infrastructure and to maximize their revenues. In this paper, we present an upcoming architecture for the transition to NGN which is future proof for going through the migration phase along with the capacity and planning of our network.
