Abstract

Bus link control in a program-controlled communication system (K) with a program-controlled HDLC control structure under the requirements of a communication system equipped with only one processor. A link processing program module (PMSA) of the HDLC control structure of the bus link discriminates between necessary and time-uncritical system tasks (NS, NSZS, ZUS) during the processing. After conclusion of the system tasks necessary in every case (NS, NSZS), a clock pulse counter (T) is interrogated, the counting pattern (Z) of which is short compared with the processing cycle (BZY). If the time value of the count (Z) of the clock pulse counter (T) is, for example, shorter than half the processing cycle (BZY), processing of time-uncritical system tasks (ZUS) is begun. <IMAGE>
