A communication connection between two internal terminals belonging to the switching system or between one such internal terminal and an external terminal is produced by an external computer system such as, for example, a data processing system or a microcomputer system. From a predetermined number of commands which can be generated and which can be used for different user programs, the commands necessary for a particular application are in each case conveyed to the communication system. At least some of these commands are structured in such a manner that they exhibit, in addition to the necessary other contents, a useful-data section by means of which at least two facility-specific and/or switching-specific sequence controls can be activated directly. Due to such a command sequence group, either the sequence controls which can be addressed by these (for example PM1, PM2) can be called up directly in succession or one sequence control is activated when the command section of such a command sequence group, which calls up the other sequence control, is ineffective due to the switching situation. One command can contain, for example, the information on the switching-over of a connection to another terminal and, at the same time, the information on the required release of a line involved in the connection. This makes it possible to [lacuna] individual triggering and ... Original abstract incomplete.
