Signaling System #7 (SS7) is a set of telephony signaling protocols which are used to set up most of the world's public switched telephone network telephone calls. The main purpose is to set up and tear down telephone calls. Other uses include number translation, prepaid billing mechanisms, short message service (SMS), and a variety of other mass market services.

It is usually abbreviated to SS7 though in North America it is often referred to as CCSS7, an acronym for 'Common Channel Signaling System 7'. In some European countries, specifically the United Kingdom, it is sometimes called C7 (CCITT number 7) and is also known as number 7 and CCIS7. (ITU-T was formerly known as CCITT.)

      Cisco SS7 Fundamentals

      Objectives This document describes the concepts and functions of Signaling System Number 7 (SS7). SS7 is widely deployed in the public switched telephone network (PSTN). It sources out-of-band signaling throughout the PSTN. Audience The guide is intended for system administrators and service technicians charged with configuring and maintaining end office switching systems.

      SS7 over IP Signaling Transport & SCTP

      Signaling Transport (SIGTRAN) is a new set of standards defined by the International Engineering Task Force (IETF). This set of protocols has been defined in order to provide the architectural model of signaling transport over IP networks. As such, only the signaling solutions are defined in this tutorial; transport of bearer traffic is not covered. Overview The communication industry is going through a period of explosive change that...

      Convergent SS7 Signaling for Seamless Service Deployment

      This paper discusses convergent Signaling System 7 (SS7) signaling for a seamless service deployment. Topics to be covered include transport, platforms, Application Programming Interfaces (APIs), and Gateways (GW) and how they affect seamless service deployment. This evolutionary area of transport and GWs will be examined as the key to providing practical, seamless services in the near term. Service infrastructure of SS7 and SS7 over...

      Signaling System 7 (SS7) Gateway Solution for Internet Access

      A signaling system 7 (SS7) gateway is an intelligent network (IN) based system that can be used in conjunction with network-access servers (NASs) to offload the circuit-switched network congestion caused by dial-up Internet users. This system is also capable of creating new services for Internet service providers (ISPs).
