Impact Levels 203
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 are not identified in any
particular way.
To ensure unrestricted functionality of the IL function you have to:
• Deactivate advisory tones for unsecured voice connections ( Page 225) and
• Deactivate automatic opening of the context menu (
 Page 230)
