Identification elements
Correctly identifying and displaying a call is the essential requirement for ad-
equately implementing the system's networking philosophy. This Chapter
looks at how the origin of a call is identified using different ringing tone pat-
terns and how the caller's number (CLIP) or name (CNIP) is displayed. It de-
scribes how CLIP and CNIP displays are created under different system condi-
tions, how they can be influenced, and how to suppress the CLIP display.
A call is identified firstly by the type of acoustic ringing (i.e. ringing pattern)
and, secondly, by the display on the terminal.
The default values are selected in such a way that the ringing patterns and
displays appear correctly in most cases. Changes to the settings are necessary
only in exceptional cases.
