Impact Levels
Impact Levels
Communication in the PSN ("Public Sector Network") is split into areas of differ-
ent impact levels (
IL
). The impact level indicates how the phone user should
handle the relevant call conversation. It is described below how to determine
whether your call partner belongs to a lower impact level when the connection
is being established or has been established.
Calls with a low impact level are treated in a particular way, either through their
own icons, text labels and/or a special ringtone. The impact level causes no re-
strictions on call handling however either during or before the call is connected.
Calls of the same or a higher
IL
are not identified in any particular way.
To ensure unrestricted functionality of the Impact Level function you have
to deactivate advisory tones for unsecured voice connections
