Abstract (en)
[origin: DE19650836C1] The invention relates to a method for measuring qualitative parameters of a message transmission link comprising a central measuring system (25) which is permanently connected to a mobile auxiliary device (12) on at least one end, said auxiliary device being connected in the vicinity of the end of the message transmission link. In order to determine the qualitative parameters of a section (7) of the message transmission link with a high degree of accuracy, a control signal is sent to the measuring system (25) via the inventive auxiliary device (12). Once the control signal is received in the measuring system (25), the message transmission link is separated into two sections (7, 8). Subsequently, the section connected to the auxiliary device (12) is verified in the measuring system (25) and the qualitative parameters of said section (7) of the message transmission link are measured.
