ABSTRACT:
For checking authorization of access to a signal processing system (SVS) from designated peripheral units (TE, BS) connected with the system, for the purpose of transmitting and, if the occasion arises, receiving signals, it is provided that a keyword is entered in the signal processing system for each peripheral unit. Such a keyword is always derived from a code number allocated to a respective peripheral unit and from identification data which is freely selectable for the respective peripheral unit. In the event of an intended access by a peripheral unit, the code number transmitted by said peripheral unit and the identification data pertaining thereto are combined with the keyword allocated to the respective peripheral unit.
