The term “signaling” consists of a word signal, which means “indication” about some information. The procedure for transfer of the signal between two nodes or points in telecom network is known as signaling. The signaling is used to transfer control information between the exchanges for call control and for the use of facilities. There are three basic phases in a communication viz setup, conversation and release. Diagram shows a simple telecom network and indicates the component of network and type of signaling used therein. Subscriber Trunk Subscriber Signalling Signalling Signalling EXCH-1 EXCH-2 FIG.1.1 Subscriber Signaling Signaling systems used between the exchange and subscriber equipment, such as terminals and PBX (Private Branch exchanges), are called subscriber signaling systems. Subscriber signaling must not be confused with line signaling. Subscriber signaling can be transported over lines and subscriber trunks. Trunk Signaling Trunk signaling are signals used between public exchanges. They are used to connect exchanges in order to build up a circuit. The signals can be divided in supervision and address signaling. -

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).
