It specifies the b

48、asic 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 tele

49、services. 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 IS0 model. The specifications contained herein apply to a DM-REP as a stand-alone unit supporting two calls on the air interface (type 2 DM-REP). They also cover the operation of a Direct Mode Mobile Station (DM-MS) with a type 2 DM-REP. NOTE 1 : The specifications for a Direct Mode RepeatedGateway (DM-REP/GATE) combined implementation are provided in ETS 300 396-5 5, together with t
