ABSTRACT:
Test system for testing a telecommunication system (1) for reliability of the usage billing. A number of simulation units (8) is connected via normal subscriber lines (7). Each includes a control unit (9) which is controlled by a control program (13) with a number of program steps (1 . . . n). Each of these includes a start code (S1 . . . Sn). A program step is executed after the control unit detects a start code signal (SCS) which is identical to the start code valid for that program step. Simultaneously, the corresponding program steps in the other simulation units are executed, which simulates the simultaneous behavior of different subscribers. In all the simulation units, the start code signals and the various start codes are identical to one another. Preferably, the program start codes and the start code signal comprise a time code. The start code signal can be an externally generated radio signal, such as the DCF77 radio time signal.
