Abstract
The system according to the invention forms part of a modem that is constituted, on the one hand, by a signal processor (60) to which is connected a read-only memory (65) and, on the other hand, by supplementary circuits such as a digital/analog converter (20) for supplying the transmission signals to the telephone line (9) and an analog/digital converter (30) for digitizing the analog signals coming from the telephone line (9). The conversions are performed at rates determined by clocks (20) and (30). Task series (CH1, CH2) bearing different degrees of priority are associated to these signals. The invention resolves the priority conflicts by closely examining the clock signals and by executing first the tasks that have the highest priority (TR1 for series CH1 and REC1 for series CH2) if the close examination of the signals proves them to have priority and then, when no priority is detected, the other tasks (TR2, GES for series CH1 and REC2 and REC3 for series CH2).
