Scope

"The present document defines the Terrestrial Trunked Radio (TETRA) Direct Mode Operation (DMO). It specifies the basic air interface@ the inter-working between Direct Mode (DM) groups via repeaters@ and inter-working with the TETRA Voice plus Data (V+D) system via gateways. It also specifies the security aspects in TETRA DMO@ and the intrinsic services that are supported in addition to the basic bearer and teleservices. This part applies to the TETRA Direct Mode Repeater (DM-REP) air interface and contains the specifications@ where applicable@ of the physical@ data link and network layers according to the ISO model. The specifications contained herein apply to a DM-REP as a stand-alone unit supporting a single call on the air interface (type 1 DM-REP). They also cover the operation of a Direct Mode Mobile Station (DM-MS) with a type 1 DM-REP. NOTE 1: The specifications for a Direct Mode Repeater/Gateway (DM-REP/GATE) combined implementation are provided in ETS 300 396-5 [5]@ together with the specifications for a Direct Mode Gateway (DM-GATE). NOTE 2: The specifications for a DM-REP as a stand-alone unit supporting two calls on the air interface (type 2 DM-REP) are provided in EN 300 396-7 [7]. The protocol for a DM-MS operating with a type 1 DM-REP is specified in clauses 5 through 8@ 10 and 11. Much of this protocol is defined in the form of a ""delta document"" relative to the specifications provided in ETS 300 396-2 [2] and ETS 300 396-3 [3] for direct MS-MS operation. These clauses define where the protocol in parts 2 and 3 applies without change@ or where it applies with the specified amendments@ replacements or additions. Where no reference to parts 2 or 3 exists@ the subclause should be regarded as independent. The protocol for the DM-REP is specified in clauses 9 and 12. The normative annex mainly specifies the parameter values used in the protocol."
