In data-communication systems, such as a public or a private telephone system, a data network or a computer communication network, it is often necessary to simultaneously establish a plurality of connections, maintaining or interrupting the same between terminals connected to the system. Apart from these communication control functions a plurality of further functions have to be carried out, such as data management, system protection and maintenance. All these functions are regarded as processes which are worked in common with other processes in parallel by the system. In order to avoid duplication of processing means and to restrict the complexity, operation in accordance with the invention is carried out so that at the beginning of the data (processing) in the central control a process is created which will carry out a function demanded, for example, by a terminal. Inside this process one or more partitions are created each for carrying out a part of the demanded function, while to each partition is allotted a local memory space which can only be used by the partition concerned. Between the partition associated with the same process an information channel is created. By arranging in one process interrelated or to be interrelated sysem partitions (in particular terminals), effective and economic data processing operation can be obtained.
