FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote interna-
tional co-operation on all questions concerning standardization in the electrical and electronic fields. To this
end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Techni-
cal Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”).
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 organiza-
tions liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Or-
ganization for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of 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 inter-
ested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinter-
pretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence be-
tween any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and ex-
penses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publica-
tions.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of pat-
ent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60728-7-3 has been prepared by technical area 5: Cable networks
for television signals, sound signals and interactive services, of IEC technical committee 100:
Audio, video and multimedia systems and equipment.
This second edition cancels and replaces the first edition published in 2003 of which it consti-
tutes a technical revision. This edition includes the following significant technical changes
with respect to the previous edition:
• All changes from standard ANSI/SCTE 25-3 v1.0 to standard ANSI/SCTE 25-3 v1.1 (2005)
have been taken into account in this second edition.
• Clause 7 is based on standard ANSI/SCTE 110 (2005).
• Addition of informative Annex A concerning hybrid management sub-layer.

INTRODUCTION
Standards of the IEC 60728 series deal with cable networks including equipment and associ-
ated methods of measurement for headend reception, processing and distribution of television
signals, sound signals and their associated data signals and for processing, interfacing and
transmitting all kinds of signals for interactive services using all applicable transmission me-
dia.
This includes
1
• CATV -networks;
• MATV-networks and SMATV-networks;
• individual receiving networks;
and all kinds of equipment, systems and installations installed in such networks.
The extent of this standardization work is from the antennas and/or special signal source in-
puts to the head-end or other interface points to the network up to the terminal input.
The standardization of any user terminals (i.e. tuners, receivers, decoders, multimedia termi-
nals, etc.) as well as of any coaxial, balanced and optical cables and accessories thereof is
excluded.
The following differences exist in some countries:
The Japanese de facto standard (NCTEA S-006) concerning requirements for the HFC out-
side plant management, which was published in 1995, has already been available in Japan.
The purpose of this standard is to support the design and implementation of interoperable
management systems for HFC cable networks used in Japan.

SOUND SIGNALS AND INTERACTIVE SERVICES –

Part 7-3: Hybrid fibre coax outside plant status monitoring –
Power supply to transponder interface bus (PSTIB)



1 Scope
This part of IEC 60728 specifies requirements for the Hybrid Fibre Coax (HFC) Outside Plant
(OSP) Power Supplies (PS). This standard is part of a series developed to support the design
and implementation of interoperable management systems for evolving HFC cable networks.
The purpose of the standards is to support the design and implementation of interoperable
management systems for evolving HFC cable networks. The Power Supply to Transponder In-
terface Bus (PSTIB) specification describes the physical (PHY) interface and related messag-
ing and protocols implemented at the Data Link Layer (DLL), layers 1 and 2 respectively in the
7-layer ISO-OSI reference model, that support communications between compliant trans-
ponders and the managed OSP power supplies and other related power equipment to which
they interface.
This standard describes the PSTIB PHY and DLL layer requirements and protocols that shall
be implemented to support reliable communications between all type 2 and type 3 compliant
OSP transponders on the HFC plant and managed OSP power supplies and related hardware.
Any exceptions to compliance with this standard will be specifically noted as necessary.
Transponder type classifications referenced within the HMS series of standards are defined in
Table 1.
