ABSTRACT:
A program-controlled communication installation is composed of at least a digital computer system having a computer core (processor) administered by a multi-tasking operating system and having a system memory wherein a plurality of program modules are stored. Each of the program modules serves the purpose of realizing a defined function of the communication installation. A function can only be executed in that the appertaining program module is handled by the computer core. Since a plurality of functions usually pend for execution, the executable program modules are noted in a process list from which the operating system respectively selects the program module having the highest priority and allocates it to the computer core for execution. In order to prevent a long duration displacement of program modules having lower priority, the program modules are combined into groups as program module function classes, each of which is respectively successively interpreted as being current for a certain chronological duration in periodic succession, whereby the operating system only takes those program modules that belong to the respectively current program module function class into consideration in the selection from the process list.
