ITU-T Q.1231

Intelligent Network Capability Set 3 (IN CS-3) is the third standardized stage of the Intelligent Network (IN) as an architectural concept for the creation and provision of services, including telecommunication services, service management services and service creation services. This Recommendation gives an introduction to IN CS-3. It describes the main characteristics and overall capabilities of IN CS-3 and defines the service aspects, network aspects and functional relationships that form the basis of the IN CS-3 capabilities. This Recommendation is the first in the Q.123x-series Recommendations devoted to IN CS-3, which builds on the architectural principles of IN as described in the Q.121x- and the Q.122x-series Recommendations. The IN CS-3 Recommendations form a detailed and stable basis for implementing IN CS-3 telecommunication services. They also provide high level guidelines for supporting service management services, service creation services and some partially supported telecommunication services. The IN CS-3 Recommendations are intended to give the same degree of technical information as the IN CS-2 Recommendations (1997).
