Abstract: A user interface for a telecommunication exchange in which the user gives control commands via the interface from an external terminal to the telecommunication exchange of which commands at least some are associated with parameters. The user interface includes control software which forwards the control command supplied by the user to the exchange for execution and gives the user instructions relating to the commands. In order that the user interface could more easily be transferred in a changed environment, the data on the types and the allowed value ranges of the parameters of the commands used in the user interface and the alphanumerical data relating to the instructions given to the user are separated from a program code of the control software into a separate database.

Abstract: The invention relates to a method of providing a subscriber-specific service by an intelligent network. In the method, a service logic program is stored in a database (BD1, DB2) of the intelligent network and a subscriber-specific service is provided by starting said service logic program in response to a predefined trigger condition. In order that subscriber-specific services could be implemented economically on a really large scale, (a) the service logic program is implemented as a service logic program (400) common to a plurality of subscribers, (b) subscriber-specific information relating to the service is stored, for each subscriber, separately from said service logic program, and (c) in the service logic program there are defined points from which the program reads, during the execution, subscriber-specific information on an individual subscriber, whereby the execution of the common service logic program with the read subscriber-specific information provides said subscriber-specific service.
