1 Scope
The multi-part deliverable EN 300 396 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 services and teleservices.
The present document applies to the general network design of TETRA DMO as follows:
• it defines and specifies the circuit mode reference points for the Mobile Station (MS), repeater and gateway to
the Switching and Management Infrastructure (SwMI);
• it defines and specifies models of the air interface protocol stack where the different functions of layers and
sub-layers are listed;
• it defines and specifies the TETRA DMO addressing and identities and their organization in groups
corresponding to the different functions;
• it defines and specifies the functions provided by the circuit mode teleservices used for speech and basic
services used for data transfer;
• it defines and specifies the intrinsic services that extend the capabilities of the circuit mode bearer services and
teleservices;
• it defines and specifies the functions related to the transport of short data messages.
NOTE: If a discrepancy occurs between the present document and any other part of the EN 300 396 multi-part
deliverable, then the other part will take precedence. This part will be updated at a frequency consistent
with maintaining the integrity of the present document as a whole.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in the ETSI Directives [i.1] and the following
apply:
Bit Error Ratio (BER): ratio of the bits wrongly received to all bits received in a given logical channel
call: complete sequence of related call transactions between DM-MSs
NOTE 1: There are two types of call, individual call or group call. An individual call is a complete sequence of
related call transactions between two DM-MSs. A group call is a complete sequence of related call
transactions involving two or more DM-MSs. The number of participants in a group call is not fixed.
Participants may join (late entry) and leave an ongoing call.
NOTE 2: For calls without presence check there is no guaranty that anyone is listening.

call transaction: all of the functions associated with a complete unidirectional transmission of information
NOTE: A call is made up of one or more sequential call transactions.
called user application: user application which receives an incoming call
calling user application: user application which initiates an outgoing call
Direct Mode Call Control (DMCC): layer 3 entity responsible for setting up and maintaining a call in DMO
Direct Mode GATEway (DM-GATE): device that provides gateway connectivity between a DM-MS(s) and the
TETRA TMO network
NOTE: The gateway provides the interface between TETRA DMO and TETRA TMO. A gateway may provide
only the gateway function (DM-GATE) or may provide the functions of both a DM repeater and a DM
gateway during a call (DM-REP/GATE).
Direct Mode Mobile Station (DM-MS): physical grouping that contains all of the mobile equipment that is used to
obtain TETRA DM services
NOTE: A DM-MS may have one of three roles:
master: if the DM-MS is either active in a call transaction transmitting traffic or control data, or is
reserving the channel by means of channel reservation signalling;
slave: if the DM-MS is receiving traffic and/or signalling in a call;
idle: if the DM-MS is not in a call.
Direct Mode Operation (DMO): mode of simplex operation where mobile subscriber radio units may communicate
using radio frequencies which may be monitored by, but which are outside the control of, the TETRA TMO network
NOTE: Direct Mode Operation is performed without intervention of any base station.
Direct Mode REPeater (DM-REP): device that operates in TETRA DM and provides a repeater function to enable
two or more DM-MSs to extend their coverage range
NOTE: It may be either a type 1 DM-REP, capable of supporting only a single call on the air interface, or a type 2
DM-REP, capable of supporting two calls on the air interface. A type 1 DM-REP may operate on either a
single RF carrier (type 1A DM-REP) or a pair of duplex-spaced RF carriers (type 1B DM-REP). A type 2
DM-REP [i.9] operates on a pair of duplex-spaced RF carriers.
DM channel: specific grouping of timeslots in the DM multiplex structure related to a particular DM RF carrier
(i.e. DM frequency)
NOTE: The grouping may not always be fixed, but in DMO when operating in frequency efficient mode as an
example, there are two DM channels, identified by the letters
