The present document specifies the following identification supplementary services: Calling Line Identification
Presentation (SS-CLIP), Connected Line Identification Presentation (SS-COLP), Calling Line Identification Restriction
(SS-CLIR) and Connected Line Identification Restriction (SS-COLR), which are applicable to various basic services
supported by TETRA Switching and Management Infrastructures (SwMIs). TETRA basic services are specified in
EN 300 392-2 [1].
Calling Line Identification Presentation (SS-CLIP) is a supplementary service which is offered to the connected user
and which provides the calling users TETRA number to the connected user.
Connected Line Identification Presentation (SS-COLP) is a supplementary service which is offered to the calling user
and which provides the called (connected) users TETRA number to the calling user.
Calling Line Identification Restriction (SS-CLIR) is a supplementary service offered to a calling user to restrict
presentation of that users TETRA number to another user.
Connected Line Identification Restriction (SS-COLR) is a supplementary service offered to a connected user to restrict
presentation of that users TETRA number to another user.
NOTE 1: For readability of the present document, and contrary to ECMA-148 [2], SS-CLIR and SS-COLR are split
in the present document.
As a TETRA network implementation option, override capability shall be provided to selected users; for a group call,
override shall be defined against the group identity and not against each individual member of the group.
NOTE 2: This capability is provided in ECMA-148 [2].
Supplementary service specifications are produced in three stages, according to the method described in
ETS 300 387 [6]. The present document contains the stage 1 specifications of SS-CLIP, SS-COLP and SS-CLIR. The
stage 1 descriptions specify the supplementary services as seen by users of SwMIs.
