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.

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).

ABSTRACT Signaling System 7 (SS7) is a global standard that defines the architecture and protocol used by Public Switched Telephone Networks (PSTN). Call Setup, call forwarding, voice mail, toll free calling, and customer billing are some of the functions of SS7. There are many different carriers providing these services. Each carrier wants to provide a high quality of service for the customer and generate revenue. To provide quality of service the carrier must ensure calls are error free.

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.
