SIGNALING in TELECOM NETWORK and SSTP (Date of Creation: 01-04-2011)
E2-E3/CFA/ Signalling in telecomN/W & SSTP Rev date: 01-04-2011 E2-E3 CONSUMER FIXED ACCESS CHAPTER-9 SIGNALING IN TELECOM NETWORK AND SSTP (Date of Creation: 01-04-2011) BSNL, India For Internal Circulation Only Page: 1 E2-E3/CFA/ Signalling in telecomN/W & SSTP Rev date: 01-04-2011 Signaling In Telecom Network And SSTP 1 .0 Introduction Communication networks generally connect two subscriber terminating equipment units together via several line sections and switches for exchange of user information (e.g. speech, data, text or images). 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. -

Petrack draft-ietf-avt-rfc2833bis-01.ps Columbia U./eDial October 21, 2002 Expires: March 2003 RTP Payload for DTMF Digits, Telephony Tones and Telephony Signals Status of this Memo This document is an Internet-Draft and is in full conformance with all provisions of Section 10 of RFC2026. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts.

Copyright Notice Copyright (c) The Internet Society (2002). All Rights Reserved. Abstract This memo describes how to carry dual-tone multifrequency (DTMF) signaling, other tone signals and telephony events in RTP packets. This document updates RFC 2833. 1 Introduction This memo defines two payload formats, one for carrying dual-tone multifrequency (DTMF) digits, other line and trunk signals (Section 3), and a second one for general multi-frequency tones in RTP [1] packets (Section 4). Separate RTP payload formats are desirable since low-rate voice codecs cannot be guaranteed to reproduce these tone signals accurately enough for automatic recognition. -

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). -

Acknowledgment
ACKNOWLEDGMENT More over I want to pay special regards to my parents who are enduring these all expenses and supporting me in all events. I am nothing without their prayers. They also encouraged me in crises. I shall never forget their sacrifices for my education so that I can enjoy my successful life as they are expecting. Also, I feel proud to pay my special regards to my project adviser "Dr. Jamal Fathi". He never disappointed me in any affair. He delivered me too much information and did his best of efforts to make me able to complete my project. I would like to thank Assoc. Prof Dr. Adnan Khashman for his advices in each stag of our undergraduate program and how to choose the right path in life. The best of acknowledge, I want to honor those all persons who have supported me or helped me in my project. I also pay my special thanks to my all friends who have helped me and gave me their precious time to complete this project. Also my especial thanks go to my friends, Ahmad Ibrahim, Mahmoud Al-Qassas and Eng. Ibrahim Abu-awwad. 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.
