scope:
EN 300 396 defies the TErrestrial Trunked RAdio system (TETRA) Direct Mode Operation (DMO). It specifies the basic air interface, the intenvorking between Direct Mode (DM) groups via repeaters, and intenvorking 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.
The present document applies to the TETRA DMO Mobile Station - Mobile Station (MS - MS) air interface and contains the specifications of the physical layer according to the OS1 seven layer reference model.
It establishes the TETRA DM radio aspects (layer 1 and lower MAC):
- it defies and specifies the modulation;
- it defies and specifies the radio transmission and reception;
- it defies and specifies the synchronization;
- it defies and specifies the channel coding;
- it defies and specifies the channel multiplexing;
- it defies and specifies the control over the radio link.
