38、adio system (TETRA) Direct Mode Operation (DMO). It specifies the basic air interface, the interworking between Direct Mode (DM) groups via repeaters, and interworking with the TETRA Voice plus Data (V+D) system via gateways. It also specifies the security aspects in TETRA DMO, and the intrinsic ser
39、vices that are supported in addition to the basic bearer and teleservices. The present document applies to the TETRA DMO Mobile Station to Mobile Station (MS-MS), DMO Type 1 repeater and DMO Gateway air interface and contains the specifications of the physical layer according to the OSI seven layer
40、reference model. It establishes the TETRA DM radio aspects (layer 1 and lower MAC): it defines and specifies the modulation; it defines and specifies the radio transmission and reception; it defines and specifies the synchronization; it defines and specifies the channel coding; it defines and specif
41、ies the channel multiplexing; it defines and specifies the control over the radio link. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
