Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives,
Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 12139-1 was prepared by Korean Agency for Technology and Standards (as KS X 4600-1)
and was adopted, under a special “fast-track procedure”, by Joint Technical Committee
ISO/IEC JTC 1, Information technology, in parallel with its approval by the national bodies of ISO and
IEC.
ISO/IEC 12139 consists of the following parts, under the general title Information technology —
Telecommunications and information exchange between systems — Powerline communication
(PLC) — High speed PLC medium access control (MAC) and physical layer (PHY):
⎯ Part 1: General requirements
Advanced MAC and PHY requirements will form the subject of a future Part 2.
Part 1 covers MAC and PHY technology for In-home/Access data networks via powerline
communications (PLC), the system of which is operating below 30MHz. The coexistence schemes will
be considered in developing Part 2, which will apply to data and high quality multimedia networks
requiring advanced MAC and PHY technology. The used or forbidden band of this standard will be
subject to national regulations.

In binary system, every number is expressed in ‘0’ or ‘1’, each of which is a bit.
3.7 Byte
A unit comprised of a set of bits, the basic unit of data representing ‘0’ or ‘1’
