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.)

      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).

      Signaling System 7 (SS7) Tutorial

      Signaling System 7 (SS7) is an architecture for performing out-of-band signaling in support of the call-establishment, billing, routing, and information-exchange functions of the public switched telephone network (PSTN). It identifies functions to be performed by a signaling-system network and a protocol to enable their performance.

Mark Twain quote for the day:

When we are young we generally estimate an opinion by the size of the person that holds it, but later we find that is an uncertain rule, for we realize that there are times when a hornet's opinion disturbs us more than an emperor's.
