pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (http://www.etsi.org/ipr).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee

server) which are, or may be, or may become, essential to the present document.
Foreword
This Candidate Harmonized European Standard (Telecommunications series) 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 Land Mobile Service; Rules for Access and the
Sharing of common used channels by equipment complying with 300 113, as identified below:
Part 1: "Technical characteristics and methods of measurement";
Part 2: "Harmonized EN covering essential requirements under article 3.2 of the R&TTE Directive".
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC [4] (as amended) laying down a procedure for the provision of information in the
field of technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Directive 1999/5/EC [1] of the European Parliament and
of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual
recognition of their conformity ("the R&TTE Directive").
National transposition dates
Date of adoption of this EN: 27 April 2001
Date of latest announcement of this EN (doa): 31 July 2001
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 31 January 2003
Date of withdrawal of any conflicting National Standard (dow): 31 January 2003

Introduction
The present document specifies an access protocol and occupation rules for data communications on radio channels
shared by different users. It may be used for data communications over channels originally intended for speech use.
This standard gives freedom for the use of any bit rate, any constant envelope modulation or any type of protocol which
fulfils the normative parameters of the present document to access a shared radio channel.
The access protocol specified in the present document also permits the sharing of speech and data communication.
The present document is part of a set of standards designed to fit in a modular structure to cover all radio and
telecommunications terminal equipment under the R&TTE Directive [1].
Each standard is a module in the structure. The modular structure is shown in figure 1.

Explanation of figure 1
The left hand edge of the figure 1 shows the different clauses of article 3 of the R&TTE Directive [1].
For article 3.3 various horizontal boxes are shown. Dotted lines indicate that at the time of publication of this standard,
essential requirements in these areas have to be adopted by the Commission. If such essential requirements are adopted,
and as far and as long as they are applicable, they will justify individual standards whose scope is likely to be specified
by function or interface type.
The vertical boxes show the standards under article 3.2 for the use of the radio spectrum by radio equipment.
For article 3.1b the diagram shows the new single multi-part product EMC standard for radio, and the existing collection
of generic and product standards currently used under the EMC Directive [2]. The parts of this new standard will
become available in the second half of 2000, and the existing separate product EMC standards will be used until it is
available (at the time of publication of the present document, the part relating to the equipment covered by the present
document is part 5).
For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive [3] and new
standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be
required.
The bottom of the figure shows the relationship of the standards to radio equipment and telecommunications terminal
equipment. A particular equipment may be radio equipment, telecommunications terminal equipment or both. One or
several radio spectrum standards will apply if it is radio equipment. An article 3.3 standard will apply as well only if the
relevant essential requirement under the R&TTE Directive [1] is adopted by the Commission and if the equipment in
question is covered by the scope of the corresponding standard. Thus, depending on the nature of the equipment, the
essential requirements under the R&
