Scope

This ETS specifies the Call Completion on No Reply (SS-CCNR) supplementary service which is applicable to various basic services supported by TETRA Switching and Management Infrastructures (SwMIs). TETRA basic services are specified in ETS 300 392-2 [8]. SS-CCNR allows completion of a call to a subscriber that was unsuccessful because of a no reply condition. SS-CCNR enables a calling user A, encountering a destination user B, that, though alerted, does not answer, to have the call completed when user B is available, without having to make a new call attempt.
