The Advanced Intelligent Network (AIN) is a telephone network architecture that separates service logic from switching equipment, allowing new services to be added without having to redesign switches to support new services.
AINs are telecommunications networks that are capable of providing advanced services through the use of distributed databases that provide additional information to call processing and routing requests. The advanced intelligent network (AIN) is a combination of the SS7 signaling network, interactive database nodes, and development tools that allow for the processing of signaling messages to provide for advanced telecommunications services.
