This European Telecommunication Standard (ETS) defines the stage 1 specifications of the Call Waiting (CW) supplementary service for the Trans-European Trunked RAdio (TETRA) as provided by European operators. Stage 1 is an overall service description from the users point of view but does not deal with the details of the human interface itself. This ETS specifies the service description of the supplementary service and the procedures to be expected with successful and unsuccessful outcomes.
