This ETS specifies the stage 2 description of the Supplementary Service Talking Party Identification (SS-TPI) for the Terrestrial Trunked Radio (TETRA). The SS-TPI supplementary service enables connected parties in a call to receive the identification of the talking party. The SS-TPI is activated against individual identity in individual call and against group identity in group calls. Man-Machine Interface and charging principles are outside the scope of this ETS.
