Summary:Comparators to control the comparison of the identity codes with the stored subscriber-specific or terminal-specific codes are assigned to the central control unit (ZS1). If they agree, and depending on the absence or presence of an additional, subscriber-specific or terminal-specific stored note bit, they control the storage or deletion of this note bit. Depending on the presence of the note bit, for every interrogation for setting up or rerouting a connection, information corresponding to all authorisations, or to only a part, is transmitted to the central control unit (ZS1). In this way, a change of authorisations can be controlled from the terminal, by plugging in means of identification.
