Impact Levels
Communication in a Public Sector Network (PSN) is split into areas of different
Impact Levels (
IL
). The Impact Level dictates how you as a user should conduct
the telephone call in question. 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. It should be noted that the Im-
pact Level causes no restriction when using the phone either during or prior to
connection. Calls of the same or a higher Impact Level
IL
are not identified in
any particular way.
To ensure unrestricted functionality of the Impact Level function, the advi-
sory tone must be disabled for unsecured voice connections
