  • On Common Channel Signaling Number 7 and Its Comparison with Multi-Frequency Coded Signaling and Internet Protocol
    International Journal of Electronics and Communication Engineering. ISSN 0974-2166 Volume 5, Number 2 (2012), pp. 125-132 © International Research Publication House http://www.irphouse.com On Common Channel Signaling Number 7 and its Comparison with Multi-Frequency Coded Signaling and Internet Protocol Md. Shah Alam1 and Md. Rezaul Huque Khan2 Dept. of Applied Physics, Electronics and Communication Engineering, University of Chittagong, Bangladesh 1 2 E-mail: [email protected], [email protected] Abstract A message based comparative study between signaling system #7(SS7) and R2 Signaling is done. The reasons for the transition from Multi-frequency Coded (MFC) Signaling to SS7 and SS7 to Internet Protocol are also discussed. Keywords: Common Channel Signaling No.7 (CCS7), R2 signaling or Multi- frequency Coded (MFC) signaling, Internet Protocol (IP), Advance Intelligent Network (AIN). Introduction The over increasing demand of telecommunication in the world wide significantly involves telecommunication signaling systems. The Common Channel Signaling no.7 is usually termed as Signaling System No.7 (SS7). The purpose of this paper is to study the signaling systems R2 or MFC, SS7 [1] and IP, to find the limitations of the above signaling system, analysis of the signaling systems (R2 and SS7) on the basis of their message format. An overall comparison between the two systems has been studied. This paper also focuses on the transition of MFC to SS7. A distinction is made between SS7 and IP and finally reasons are shown why SS7 is moving towards IP. Common Channel Signaling No. 7 Common Channel Signaling System No. 7 (i.e., SS7 or C7) is a global standard for telecommunications defined by the International Telecommunication Union (ITU) Telecommunication Standardization Sector (ITU-T).

Univ.-Prof. Dr. Mehdi Jazayeri Second Advisor: a.o. Univ.-Prof. Dr. Gabriele Kotsis Abstract In this thesis, we present Omnix, a Peer-to-Peer (P2P) middleware framework. P2P mid- dleware provides an abstraction between the application and the underlying network by pro- viding higher-level functionality such as distributed P2P searches and direct communication among peers. P2P networks build an overlay network, a network on the network. The central idea of this dissertation is to apply the well-established ISO OSI layered model on P2P middleware systems. A layered P2P architecture helps to identify separate parts of a complex system, allows changes to the system without affecting other layers and makes maintenance easier due to modularization.

ISBN 5820601068 The monograph "Evolution of Telecommunication Protocols" is devoted to a wide range of questions related to signaling protocols in telephone networks of former USSR Public Switched Telephone Networks. The SDLoriented analysis method enabling the description in a relatively simple way of the specifics of interoffice signaling systems and call handling procedures, as well as specifications and scenarios required for designing is discussed. The evolution of Russian interoffice signaling systems, from threewire trunks and so called "R 1.5" to Signaling System No.7 protocols is considered. All engineering solutions are directed toward uptodate digital switching nodes and exchanges. The book is primarily intended for engineers and scientists involved in the research, development, and operation of switching nodes. The book will be a valuable reference source for students and post graduates studying in these areas. Technical edition All right reserved. Copyright © Boris S.

Power Line Communications (PLC) or Broadband over Power Lines (BPL) is the method of transmitting broadband signals over the power lines and making it available at the power outlet in homes. It provides last mile communication and makes use of existing power lines to transmit signals, thereby eliminating the need to lay cables all over again. PLC is fast becoming a commercial reality in the United States.
