Nearly every operator in the world depends on SS7. For good reason: SS7 was massively adopted throughout the world and brought ubiquitous and nearly seamless interconnection to the international telecommunications industry. And despite new signaling technologies, SS7 remains the backbone of most successful network operations. All indicators point to SS7 not only surviving for the next 10 to 20 years but growing before eventually reaching endof- life. The fact is, SS7 may continue to provide significant income well after its expected end-of-life. Underpinning the SS7 network is the Signal Transfer Point (STP) application, and as STPs will still provide the vast majority of signaling support for SS7/TDM, it certainly will play a role in the transition to next-generation Diameter-based networks. However, there are only two things holding back even more profitable SS7/STP: legacy hardware and limited vendors. The older hardware STP systems become, the more costly they will be to support, replace, and maintain down the line. Replacement with modern, agile, and extensible software systems adds greater simplicity, flexibility, and increased cost efficiency. A software-based solution provides an open path to new telecom services with lower costs and greater performance yet preserves and even grows SS7 revenue.
