Abstract: A method and an arrangement for trying out in advance prerequisites for introducing new services in a telecommunications system. A base system is described by a specification language, a new service is described by the specification language as separate supplement to the base system description. The base system description and supplement are linked together to form a description of the total resultant system. The total system is then analysed, for example by a reachability analysis. The invention also relates to an arrangement for carrying out the method. The invention solves the technical problem of identifying problems of an interservice interference type with respect to specific services at an earlier stage.

Abstract: An apparatus for aseptically filling and sealing bottles with a liquid preparation includes a plurality of treatment stations in which bottles are successively placed in bottle holding devices, evacuated and flushed or rinsed with an inert gas, filled with the liquid preparation, sealed and removed from the bottle holding devices, all in a system which is sealed from the exterior. The transporting system is adapted to provide a successive, relative movement between the bottles in the holding devices and the treatment stations. The system, which is sealed from the exterior, is provided with known sealing lock arrangements for the sterile introduction of empty bottles, liquid preparation and connections for the discharge of filled and sealed bottles, all while maintaining sterile conditions in the apparatus.
