While there are many scholarly books and papers that cover the technical issues behind the public switched telephone network (PSTN) migration, few books describe exactly how to manage the migration process economically. Filling this need, Managing the PSTN Transformation: A Blueprint for a Successful Migration to IP-Based Networks reflects the latest understanding of the challenges behind migrating customers from the old PSTN network to an IP infrastructure. The IP transformation blueprint described in this book is not a theoretical cookbook that describes how this could work. Instead, the book presents a blueprint that is the product of countless hours of work by hundreds of individuals at Deutsche Telekom (DT) over almost two years. The book presents insights gained as the DT team migrated the entire public switched telephone network in Macedonia to an Internet protocol-based platform. It illustrates the various types of challenges the team faced in integrating complex systems, including flight control at their airports, alarms for fire and police response, and large enterprise customers. Detailing new conceptual approaches and the best practices developed for ensuring knowledge transfer within the DT group, the book presents the information in a step-by-step manner to enable you to easily adapt the blueprint for particular service provider requirements. Since successful migration relies on key aspects beyond the technological side, this work provides you with a product portfolio roadmap, migration plan, IT roadmap, business case framework, and a go-to-market plan. Although the book discusses the experiences of the Deutsche Telekom team as they worked to migrate the telephone network in Macedonia to an Internet protocol-based platform, the IP transformation blueprint and lessons learned presented can easily be scaled up and applied to any market around the world.

The concept of transmitting information from one chaotic system to another derives from the observation of the synchronization of two chaotic systems. Having developed two chaotic systems that can be synchronized, scientists can modulate on one phase signal the information to be transmitted, and subtract (demodulate) the information from the corresponding phase signal of the coupled chaotic system. Chaos Applications in Telecommunications demonstrates this technique in various applications of communication systems. This book details methods of transmitting information at much higher levels of security than what is available by current techniques. Following a detailed introduction, the book demonstrates how chaotic signals are generated and transmitted. It then details the design of chaotic transmitters and receivers, and describes chaos-based modulation and demodulation techniques. The text describes how a chaos-based spreading sequence outperforms classical pseudorandom sequences in selective and nonselective channels. It also develops channel equalization techniques designed for chaotic communications systems by applying knowledge of systems dynamics, linear time-invariant representations of chaotic systems, and symbolic dynamics representations of chaotic systems. The final chapter explains a specific application for optical communications. This volume provides the essential information for those who want an integrated view of how an established concept such as chaos can open new roads in the communications and security fields.
