Foreword
This European Telecommunication Standard (ETS) has been produced by the Radio Equipment and
Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI).
The binary signalling procedure described in this ETS is an alternative to existing calling systems such as
single-tone, multitone, subaudio and double-tone.
Every I-ETS and ETS prepared by ETSI is a voluntary standard. This ETS contains text concerning
conformance testing of the equipment to which it relates. This text should be considered as guidance only
and does not make this ETS mandatory.
Transposition dates
Date of adoption of this ETS: 8 November 1996
Date of latest announcement of this ETS (doa): 28 February 1997
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 31 August 1997
Date of withdrawal of any conflicting National Standard (dow): 31 August 1997

1 Scope
This ETS describes a binary signalling and data transmission system for private radio equipment operating
at 1 200 bit/s using indirect modulation.
This ETS applies to systems operating on either shared, or exclusive, channels.
According to national regulations of various countries, Public Switched Telephone Network (PSTN) access
and data transmission can be subject to licensing. The channel access protocol and occupation rules can
also be a matter for licensing, depending on the different national regulations.
This ETS permits the addition, if necessary, of supplementary signalling, either sub-audio, multitone, or
binary, as appropriate, to permit primary and secondary paging to be used. This ETS does not attempt to
define the protocols necessary for such supplementary signalling.
Where parameters relating to the radio environment are specified, reference should be made to the
appropriate clauses of ETS 300 113 [3]. However, selective calls according to this ETS can be
implemented in equipment fulfilling I-ETS 300 219 [2] (that is messages of categories 0, 2, 4, 5 and
messages of category 1 and functions 0, 1 and 2 as defined in subclause 7.2 of this ETS).
2 Normative references
This ETS incorporates by dated or undated reference, provisions from other publications. These normative
references are quoted at the appropriate places in the text and the publications are listed hereafter. For
dated references subsequent amendments to or revisions of any of these publications apply to this ETS
only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply:
address: Information which consists of a Regional Code, a common address part, and an individual
number or a group number.

ETS 300 230: November 1996
address block: A block containing addresses. The first block of a transmission is always an address
block. It can be followed by other address blocks (subclause 7.1).
address codeword: A 64-bit codeword. The first 48 bits contain the information, the remaining 16 bits
contain the redundancy for the data protection. The first codeword of a transmission is always an address
codeword that can be followed by others.
