Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Electromagnetic compatibility and
Radio spectrum Matters (ERM).
The present document is part 3 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".
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of

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 [3].
The present document describes the packet data protocol (PDP) 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 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 Packet Data Protocol (PDP) 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.
