another cell coverage area and dependent on available traffic channels, this operation is seamless.
3.2.2 Caller Line Identity Presentation CLIP
The calling party TETRA identity may be transported as part of the incoming individual call set-up
signalling. If the identity can be interpreted as a short number, the short number will be displayed to
the user. In addition, if the number is programmed in the terminal address book, the name
associated with that number will be displayed as well. If the calling party identity is not present in the
call set-up signalling, the terminal will display a blank line in place of the missing identity.

❏ If caller is programmed in terminal’s list the alias is displayed

This is a system feature that enables terminal users to dial telephone numbers and have a full
duplex, one to one call with the called party.
