  • all internal devices that are connected to the communication system and support a certain service (eg an analog or digital voice service) combined in an alarm class.
  • Another problem with this method is that a functional classification of the alarm classes according to the different types of peripheral elements, in the event of an alarm, means that the peripheral element which triggers the error cannot be identified easily.
  • the invention is based on the object of specifying a method by means of which a local assignment of an alarm to a peripheral element is possible in a simple manner.
  • An important advantage of the method according to the invention is that no changes to the interfaces to the peripheral elements are required when implementing the alarm concept according to the invention.
