<p>The invention concerns a system associated with the terminal (30) of a telecommunication line (10), characterised in that it comprises: at least a detector of local and behavioural parameters inherent to the use of said terminal, a device (60) for analysing relevant parameters for determining the impropriety of an opened state of the line (10), based on signals derived from the sensor (50), and a device (70) for controlling a tap unit capable of deactivating, in on-hook condition, the telecommunication line (10), when said analysing device (60) determines that the opened state of the line (10) is improper.</p> |
