Introduction
EN 50173-4 specifies generic cabling in homes, installed to support one or more of the following groups
of applications and based upon balanced and coaxial cabling as appropriate:
a) Information and Communication Technologies (ICT);
b) Broadcast and Communication Technologies (BCT);
c) Command, Controls and Communications in Buildings (CCCB).
EN 50173-4 also provides requirements for backbone cabling subsystems within premises containing
multiple homes by reference to:
1) EN 50173-1 for cabling to support ICT applications;
2) standards of the EN 50083 and EN 60728 series to support BCT applications.
EN 50083 and EN 60728 standards deal with cable networks including equipment and associated
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 media including community antenna
television (CATV) and master antenna television/satellite master antenna television (MATV/SMATV)
networks.
This Technical Report describes the following:
– the functional elements and structure of the cabling, external to homes, supporting community
antenna television (CATV) and master antenna television/satellite master antenna television
(MATV/SMATV) networks in accordance with EN 60728-1;
– the location and accommodation of the home network interface (HNI) in accordance with EN 60728-1;
– requirements for additional cabling performance requirements (i.e. insertion loss slope between
47 MHz and 862 MHz) and necessary amendments of the reference implementations of generic
cabling within the home in accordance with EN 50173-4 in order to support the CATV, MATV/SMATV
networks in accordance with EN 60728-1.
