The system (1) for processing a cable (5) comprises a first set of tools (30(i)), a second set of tools (35(j)) and a processing device (10) for executing different processing steps for processing a cable (5) using at least two tools (30(i), 35(j)). The processing device (10) comprises: a first holding device (15), which is intended for the purpose of removably holding a first tool (30(i)) which is selected from the first set of tools, and a second holding device (16), which is intended for the purpose of removably holding a second tool (35(j)) which is selected from the second set of tools, at least one tool of the first set being suitable for processing the cable exclusively in combination with one of the tools of a predetermined partial set of the second set. A test unit (40) comprises identification means (45) for identifying the first tool (30(i)) and the second tool (35(j) and a check device (55) for checking whether the identified tools (30(i) 35(j)) are each tools which are suitable for processing in combination with one another.
