¿µ¹®³»¿ë¿ä¾à | The present document defines the stage 3 specifications of the Supplementary Service Call Authorized by Dispatcher (SS-CAD) for the Terrestrial Trunked RAdio (TETRA). Stage 3 defines the signalling system protocols needed to implement the service described in stage 1 and stage 2. The stage 1 and stage 2 aspects are detailed in EN 300 392-10 6 and EN 300 392 11 6 respectively. Aspects relating to all supplementary services are detailed in EN 300 392 9.
The SS-CAD ensures that predefined TETRA calls do not proceed without first being authorized by a dispatcher. |
