Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Electromagnetic compatibility and
Radio spectrum Matters (ERM).
The present document is part 2 of a multi-part deliverable covering the Technical Requirements for Digital Mobile
Radio (DMR), as identified below:
Part 1: "DMR Air Interface (AI) protocol";
Part 2: "DMR voice and generic services and facilities";
Part 3: "DMR data protocol";
Part 4: "DMR trunking protocol".

1 Scope
The present document contains technical requirements for Digital Mobile Radio (DMR) operating in the existing
licensed land mobile service frequency bands, as identified in CEPT/ERC/T/R 25-08 [i.1].
The present document describes the voice and generic services and facilities of a scalable Digital Mobile Radio system
which covers three tiers of possible products:
Tier I: DMR equipment having an integral antenna and working in direct mode (communication without
infrastructure) under a general authorization with no individual rights operation.
Tier II: DMR systems operating under individual licences working in direct mode (unit-to-unit) or using a
Base Station (BS) for repeating.
Tier III: DMR trunking systems under individual licences operating with a controller function that
automatically regulates the communications.
NOTE 1: Tier II and Tier III products encompass both simulcast and non-simulcast systems.
NOTE 2: The three tiers of possible products will work only independently and not interoperable.
The present document specifies the voice and generic services and facilities of DMR that has been specifically
developed with the intention of being suitable for all identified product tiers. The DMR protocol is intended to be
applicable to the land mobile frequency bands, physical channel offset, duplex spacing, range assumptions and all other
spectrum parameters without need for any change.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
1:1-mode: 1 traffic channel mode
NOTE: 1:1-mode supports one "MS to fixed end" duplex call or one simplex call with an optional inbound
Reverse Channel using a two frequency BS.
2:1-mode: 2 traffic channel mode
NOTE: 2:1-mode supports two independent calls which may be either "MS to fixed end" duplex calls, simplex
calls using a two frequency BS or simplex calls between MS units on a single frequency.
Base Station (BS): fixed end equipment that is used to obtain DMR services
bearer service: telecommunication service providing the capability for information transfer between access points
burst: elementary amount of bits within the physical channel
NOTE 1: Three different bursts exist with different number of bits. The Traffic burst contains 264 bits, the CACH
burst contains 24 bits and the RC burst contains 96 bits.
NOTE 2: The burst may include a guard time at the beginning and end of the burst used for power ramp-up and
ramp-down.
NOTE 3: For detailed burst definition see clause 4.2.1.
call: complete sequence of related transactions between MSs
NOTE: Transactions may be one or more bursts containing specific call related information.
channel slot timing: time slot 1 and time slot 2 timing boundaries established by a TDMA direct mode leader
Control plane (C-plane): part of the DMR protocol stack dedicated to control and data services
Digital Mobile Radio (DMR): physical grouping that contains all of the mobile and/or fixed end equipment that is
used to obtain DMR services
direct mode: mode of operation where MSs may communicate outside the control of a network
NOTE 1: This is communication technique where any radio unit (MS) may communicate with one or more other
radio units (MSs) without the need for any additional equipment (e.g. BS).
NOTE 2: Supports one transmission per 12,5 kHz frequency; 12,5 kHz equivalent (12,5e) spectral efficiency.
duplex: a mode of operation by which information can be transferred in both directions and where the two directions
are independent
NOTE: Duplex is also known as full duplex.
frame: two contiguous time slots labelled 1 and 2
NOTE: A frame has a length of 60 ms.
inbound: MS to BS transmission
logical channel: distinct data path between logical endpoints
NOTE: The logical channels are labelled 1 and 2. The logical channel may consist of sub-channels, e.g. SYNC,
embedded signalling, etc.
ETSI
10 ETSI TS 102 361-2 V2.2.1 (2013-07)
Mobile Station (MS): physical grouping that contains all of the mobile equipment that is used to obtain DMR mobile
services
octet: 8 bits grouped together, also called a byte
outbound: BS to MS transmission
payload: bits in the information field
personalization: address and configuration information that characterizes a particular DMR MS
NOTE: This information may be programmed by the installer before putting an MS into service.
physical channel: RF carrier that is modulated with information bits of the bursts
NOTE: The RF carrier may be a single frequency or a duplex pair of frequencies. The physical channel of a DMR
subsystem is required to support the logical channels.
polite protocol: "Listen Before Transmit" (LBT) protocol
NOTE: This is a medium access protocol that implements a LBT function in order to ensure that the channel is
free before transmitting.
prefix: most significant digit of a MS address in the user domain
privacy: secret transformation
NOTE: Any transformation of transmitted information that is derived from a shared secret between the sender and
receiver.
Protocol Data Unit (PDU): unit of information consisting of protocol control information (signalling) and possibly
user data exchanged between peer protocol layer entities
Radio Frequency channel: Radio Frequency carrier (RF carrier)
NOTE: This is a specified portion of the RF spectrum. In DMR, the RF carrier separation is 12,5 kHz. The
physical channel may be a single frequency or a duplex spaced pair of frequencies.
repeater mode: mode of operation where MSs may communicate through a BS
NOTE: This is a communication technique where any radio unit (MS) may communicate with one or more other
radio units (MSs) with the need for an intermediate BS.
signalling: exchange of information specifically concerned with the establishment and control of connections, and with
management, in a telecommunication network
simplex: mode of working by which information can be transferred in both directions but not at the same time
superframe: 6 continues traffic bursts on a logical channel labelled "A" to "F"
NOTE: A superframe has a length of 360 ms and is used for voice traffic only.
TDMA direct mode: direct mode operation that supports two transmissions per 12,5 kHz frequency
NOTE: Supports 6,25 kHz equivalent (6,25e) spectral efficiency.
time slot (or slot): elementary timing of the physical channel
NOTE: A timeslot has a length of 30 ms and will be numbered "1" or "2".
transmission: transfer period of bursts containing information or signalling
