STANDARDIZATION OF INTERCONNECTIONS BETWEEN
BROADCASTING TRANSMITTERS OR TRANSMITTER SYSTEMS
AND SUPERVISORY EQUIPMENT –
Part 2: Interface standards for systems using
data bus type interconnections
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60864-2 has been prepared by technical committee 103:
Transmitting equipment for radiocommunication.
The text of this standard is based on the following documents:
FDIS Report on voting
103/3/FDIS 103/6/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
IEC 60864 consists of the following parts, under the general title Standardization of
interconnections between broadcasting transmitters or transmitter systems and supervisory
equipment:
– Part 1: Interface standards for systems using dedicated interconnections;
– Part 2: Interface standards for systems using data bus type interconnections.
Annexes A, B and C are for information only.

INTRODUCTION
The majority of broadcasting transmitting stations are designed and constructed to operate
unattended, that is without personnel being present in the same room as the transmitter.
Normally, supervisory equipment is installed which continuously monitors and sometimes
controls the operation of the transmitters. The supervisory equipment may range from a simple
unit which merely extends indications and controls into an adjacent room, to a highly
sophisticated system enabling a large number of transmitters to be controlled from a common
point.
The majority of existing transmitters employ wired interconnections; however, the advent of
microprocessors and software techniques will require different interconnection methods, for
example, by means of optical fibres.
It therefore seems appropriate to divide IEC 60864 into two parts, part 1 dealing with dedicated
interconnections and part 2 dealing with data bus type interconnections.

STANDARDIZATION OF INTERCONNECTIONS BETWEEN
BROADCASTING TRANSMITTERS OR TRANSMITTER SYSTEMS
AND SUPERVISORY EQUIPMENT –
Part 2: Interface standards for systems using
data bus type interconnections
1 Scope
This part of IEC 60864 is applicable to all classes of transmitters for sound and television
broadcasting. This standard may not, however, be appropriate for low power equipment, for
simple transmitting systems which consist of a small number of controlled equipment items and
for certain special purpose transmitters.
Any facilities and interconnections not directly associated with the transmitters, for example
intruder alarms, mast lighting, etc., are excluded from this standard.
This part of IEC 60864 deals with the interface between a transmitter (or system of
transmitters) and the supervisory equipment which is intended to remotely monitor and/or
control the transmitter(s). It details the interconnections and facilities to be provided with a view
to achieving compatibility between different types and makes of transmitters and supervisory
equipment.

3 General aspects
3.1 Definitions
For the purpose of this part of IEC 60864, the following definitions apply.
3.1.1 (N + 1) dedicated reserve system: (N + 1) reserve system where the same transmitter
is always dedicated as the reserve.

60864-2 © IEC:1997 – 11 –
3.1.2 (N + 1) reserve system: System of transmitters in which only one reserve is provided
for N (N > 1) transmitters in operation.
See figure A.5.
3.1.3 active reserve: System of transmitters in which the reserve is in continuous use and
contributes to the output power, for example, parallel operation.
See figure A.3.
3.1.4 alarm: Indication of an abnormal status.
3.1.5 automatic: Term used to describe a system which acts in a predetermined way, without
the external intervention of an operator.
See figure 1.
3.1.6 automatic changeover: Changeover action, which occurs in a preselected way, without
the external intervention of an operator.
3.1.7 basic transmitter: Individual transmitters in a system consisting of more than one
transmitter.
3.1.8 changeover: Transfer from one signal path or item of equipment to another, normally a
spare or reserve, provided as part of a transmitter system.
3.1.9 command: Action by means of which any part of a transmitter system is made to
change its status.
3.1.10 command circuit: Circuit in a supervisory system, by means of which each command
is sent to the transmitter.
3.1.11 control system: System used to operate a transmitter, transmitter system and/or the
associated equipment by means of one or more commands.
See figure 1.
3.1.12 drive (excitation) (exciter): Low level radio frequency part of a transmitter or
transmitter system.
The drive may be either
– unmodulated, for example, a simple crystal oscillator (sometimes referred to as
excitation), or
– modulated, sometimes followed by amplifiers to form a "drive transmitter".
See figure A.6.
3.1.13 fault (failure) (fail): Abnormal condition of the equipment which usually results in the
generation of an alarm.
3.1.14 indication: Information concerning the statu
