摘要

The invention relates to a method and an arrangement for monitoring of voice and/or data network connections, independent of location, by authorities, such as national criminal authorities, regional criminal authorities, customs authorities and state authorities with legal authorisation, in particular for carrying out the method as according to one of the claims. The above comprises a preparatory device (12), with an arrangement for passive switching onto at least one bi-directional voice and/or data network connection (26) for monitoring, a device (40), for synchronising with data transmission protocols and data frames, a device for selection, localisation and separation from synchronised protocols and/or data, a device for reading off data, events and event sequences relevant to the monitoring, a transmission device (14), connected to the preparatory device (12) and a receiver device (18), communicating with the transmission device for transmission of the read data, events and event sequences from the transmission device (14), independent of the transmitted and received data, events and event sequences, by means of at least one transit network with at least one channel for the receiver device (18) for preparation and compiling the separately transmitted data, events and event sequences for a location provided for analysis thereof.
