Intelligent Network Implementation Examples

Abstract

The CCITT (now ITU-T) Intelligent Network CS1 series of recommendations have been approved by the WTSC in spring 1993 (Q.121x). Based on the ITU-T CS1 recommendation Q.1218 ETSI developed the ETSI Core INAP CS1. The Public Enquiry of this ETS has just been successfully finished. Siemens was engaged during the whole study period in the specification of the IN recommendations and ensured a continuous feed back of IN Capability Set 1 standardisation results into the company's ongoing IN product development concerning Intelligent Networks. The Siemens IN systems, which will be delivered one year after approval of IN CS1 recommendations, are compatible to IN CS1, i.e. the design of these systems has been based on IN CS1 recommendations. Besides naturally enhanced capabilities compared to preceding systems one of the essentially new feature of these products is the support of the ETSI Core INAP. It is to note that the Siemens pre-CS1 IN systems as well as the IN CS1 conforming systems comprise several system components and capabilities which are additionally to IN CS1. This results from the fact that several essential parts of an IN system are not specified within those recommendations, i.e. currently not standardised capabilities like for example: - service creation environment, - service management services, - IN system management services, - service provider administration services, - service subscriber administration services, - etc..
