GENERIC CABLING FOR HOMES
FOREWORD
1) ISO (International Organization for Standardization) and IEC (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.
2) In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting.

Introduction
This standard specifies a generic cabling for three groups of applications in homes:
• Information and Communications Technologies (ICT);
• Broadcast and Communications Technologies (BCT);
• Commands, Controls and Communications in Buildings (CCCB);
as shown in Figure 1, and it is intended to guide installations in new buildings or
refurbishments. (Cabling is a part of the infrastructure that supports home systems.)
This standard also applies where cabling is installed to support only one or two of the three
application groups listed above.
This standard specifies a generic cabling infrastructure based upon balanced cabling and/or
coaxial cabling. ICT channels specified in this standard include optical fibre. The wider use of
fibre optical cabling in a home is for further study.
These groups of applications may also be supported by different types of cabling, which may
be subject to other standards. For example, ISO/IEC 11801 specifies generic cabling for ICT
applications in general for the office environment. While the cabling structure and reference
implementations are matched to the home environment in this standard, the channel
performances specified for ICT are identical to those specified in ISO/IEC 11801.
This standard specifies a generic cabling for a home that may support ICT, BCT and CCCB
application groups. Because it is designed to cover the three major groups, the cabling
system may be installed prior to the selection of specific applications. The home may contain
one or more buildings (e.g. farm) or may be within a building which contains more than one
home (e.g. one home in a multi-dwelling building).
The campus or backbone cabling connecting individual homes is built according to the
relevant standard (for instance ISO/IEC 11801 or IEC 60728).
Generic cabling realised according to this standard:
a) allows deployment of a wide range of applications without changes to the fixed cabling
infrastructure;
b) provides a platform to support moves, adds and changes of connectivity.
This standard provides:
• users with an application-independent generic cabling for applications run in homes;
• users with a flexible cabling scheme such that changes are both easy and economical;
• building professionals (for example, architects) with guidance for accommodating cabling
before specific requirements are known, i.e. in the initial planning either for construction or
refurbishment;
• industry and applications standardisation bodies (e.g. ITU-T, ISO/IEC JTC 1/SC 6,
ISO/IEC JTC 1/SC 25/WG 1, IEC TC 100) with a cabling system that supports current
products and provides a basis for future product development in home electronic systems;
• users, designers and manufacturers of application-specific cabling systems with advice on
interfacing to this generic cabling;
• suppliers of cabling components and installers of cabling with relevant requirements;
• service providers with a distribution system for their services.

A number of ICT, BCT and CCCB applications have been analysed to determine the
requirements for a generic cabling (see Table D.2) and to specify the minimum performance
of channels given in clause 7. These requirements, together with the logical and physical
models described in clauses 5 and 6, have been used to develop the requirements for cabling
components and to stipulate their arrangement into generic cabling systems.
Wireless and (unguided) infrared as well as Power Line Communication may also be used for
applications mentioned above. Media used for these technologies are not covered in this
standard.

Information technology - Generic cabling for homes
1 Scope
This International Standard specifies generic cabling for homes. A home may contain one or
more buildings or may be within a building that contains more than one home.
This standard specifies a generic cabling for three groups of applications:
• Information and Communications Technologies (ICT);
• Broadcast and Communications Technologies (BCT);
• Commands, Controls and Communications in Buildings (CCCB).
It specifies cabling that comprises one or more of the following:
• balanced cabling;
• coaxial cabling;
• optical fibre cabling.
The standard specifies the requirements for the design and configuration of the generic
cabling with respect to:
a) structure and topology;
b) minimum configuration;
c) performance requirements for permanent links and channels;
d) density and location of connection points;
e) interfaces to application-specific equipment and external networks;
f) coexistence with other building services.
Although safety (electrical, fire, etc.) and electromagnetic compatibility (EMC) requirements
are outside the scope of this International Standard and are covered by other standards and
regulations, information given in this International Standard may be of assistance in meeting
these requirements.
NOTE 1 National regulations and local codes may preclude carrying certain services on the cabling specified in
this standard.
NOTE 2 • Test requirements in this standard are for system designers.
• The installation tests should be decided between supplier and customer or according to the relevant
installation guide.
