Overview

CLC/TR 50173-99-3:2012 is a CLC Technical Report that extends the EN 50173 series by describing a practical grading system for home cabling infrastructures up to 50 m. It targets residential telecommunications cabling that must support both simultaneous and non‑simultaneous provision of applications (ICT, broadcast and related services). The report offers simplified implementation options compared with EN 50173‑4 while defining connector pin assignments, component requirements and shorter channel lengths to enable robust in‑home networks.

Key topics and requirements

• Grading system for home cabling: Defines multiple grades (e.g., Grade 1, Grade 3, Grade 3S) to match different performance and deployment needs without the full complexity of EN 50173‑4.
• Channel length limitation: Specifies infrastructure solutions for cabling channels up to 50 m, enabling reduced attenuation and supporting simultaneous services such as telephony and 100BASE‑T.
• Application Outlet (AO) concept: Uses a balanced cabling outlet to support multiple ICT and broadcast applications (simultaneous or non‑simultaneous).
• Components and connectors: Recommends components that meet or exceed EN 50173‑4 requirements and references connector specifications (EN 60603‑7 series, EN 61076, radio‑frequency connectors).
• Balanced and coaxial options: Covers balanced cabling and coaxial (BCT‑C) or balanced (BCT‑B) broadcast solutions appropriate for in‑home distribution.
• Pin assignment and equipment cords: Provides guidance on interface pin grouping and equipment/patch cord uses for multi‑application outlets.
• Implementation guidance: Aligns with installation planning and quality practices from the EN 50174 series; includes AO faceplate and distribution examples.
• Scope limits: Electrical safety, optical power, fire, and EMC are outside the report’s scope but it provides information that can assist compliance with those standards and regulations.

Applications and practical value

• Design and specification of residential structured cabling for single‑family homes and apartments.
• Supporting mixed services: Ethernet data, telephony (xDSL/VDSL), DVB/TV distribution and interactive broadcast services.
• Enabling shorter, high‑quality channels for simultaneous application provision (e.g., data + telephony).
• Useful for architects, network designers, installers, system integrators, building owners and product manufacturers planning in‑home ICT/BCT deployment.

Who should use this standard

• Cabling installers and integrators delivering home networking services
• Network planners and specifiers writing installation requirements
• Manufacturers of connectors, faceplates and residential cables
• Building owners and facility managers specifying future‑proof home cabling

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 50083 (all parts) and EN 60728 (all parts) 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.
The EN 50174 series specify the specification, planning and practices applicable to installation
of telecommunications cabling within homes.
This Technical Report describes a grading system applicable to telecommunications cabling
within homes which provides a range of implementation solutions to support both non-
simultaneous and simultaneous provision of applications incorporating:
1) a cabling structure in accordance with, but less complex than that of, EN 50173-4 and with
defined connecting hardware pin assignment for certain applications;
2) components meeting or exceeding the requirements of EN 50173-4;
3) shorter cabling channels than those specified in EN 50173-4 (simultaneous transmission of
telephony and 100BASE-T is supported by the reduced channel attenuation resulting from
the restriction of maximum channel lengths to 50 m).

4 Cabling infrastructure
4.1 Home cabling in accordance with EN 50173-4
EN 50173-4 defines two generic cabling structures (see Figure 1) to support the delivery of ICT
and BCT applications within the home:
a) between the home distributor (HD) and a telecommunications outlet (TO) for the delivery of
those services using ICT applications over balanced or optical fibre cabling;
b) between the HD and a broadcast outlet (BO) for the delivery of those services using BCT
applications over either coaxial (BCT-C) or balanced (BCT-B) cabling.
NOTE The inclusion of optical fibre to deliver BCT applications may be included in
EN 50173-4:2007/A2:201X.
For the purposes of this Technical Report, a more general term Application Outlet (AO) is used
to describe a balanced cabling outlet that supports simultaneous and non-simultaneous
provision of multiple ICT and BCT applications.

Figure 1  Home cabling for ICT and BCT applications according to EN 50173-4
CLC/TR 50173-99-2 provides additional detail regarding the implementation of BCT-C and
BCT-B cabling for applications in accordance with the EN 60728 series of standards.
Figure 1 shows the connection of the cabling to equipment at the HD. Alternatively, the cabling
may be connected directly to an external network interface (ENI) as described in EN 50173-4
which may be accommodated in the primary distribution space or home entrance space (see
EN 50174-2). In the case of BCT applications, this is more accurately described as a Home
Network Interface (HNI) as described in CLC/TR 50173-99-2.
The ENI is connected via application-specific network access cabling (see 4.4.3) to:
1) other equipment within the home (e.g. a satellite antenna);
2) other equipment within the access network;
3) within multi-tenant premises, to a building network interface within a building entrance
space.
The signal levels at HNIs are assumed to meet the requirements of EN 60728-1.
4.2 Application support
The balanced cabling for BCT applications specified in EN 50173-4 assumes a single-pair
implementation. The balanced cabling for ICT applications specified in EN 50173-4 assumes a
multi-pair implementation but is “not guaranteed to support the simultaneous transmission of
different applications … within a cable or at an interface to the generic cabling” and that “the
sharing of components by applications … may require additional performance requirements to
be applied.” This applies to simultaneous provision of two identical applications or of different
applications.
The specification of multi-pair balanced cabling to support the simultaneous provision of
multiple ICT and BCT applications requires a modification of the implementations specified in
EN 50173-4.
For example, the BCT applications providing radiofrequency transmission in the very high
frequency and ultra high frequency (VHF/UHF) bands of analogue television and terrestrial
digital video broadcast (DVB-T) use signal voltages in the mV range. In comparison, ICT
applications use signal voltages of the order of 1 V. As a result specific provisions are needed
to avoid electromagnetic disturbance on BCT applications.

In order to support ICT applications in addition to those of EN 50173-4 and to support
simultaneous provision of specific combinations of those applications (as shown in Figure 2),
this Technical Report specifies an infrastructure grading scheme utilising:
a) a cabling structure in accordance with, but less complex than that of, EN 50173-4 and with
defined connecting hardware pin assignment for certain applications;
b) components meeting or exceeding the requirements of EN 50173-4;
c) shorter cabling channels than those specified in EN 50173-4 (simultaneous transmission of
telephony and 100BASE-T is supported by the reduced channel attenuation resulting from
the restriction of maximum channel lengths to 50 m).

4.3 Home infrastructure grading scheme
4.3.1 Infrastructure grades
In order to support a range of specific combinations of non-simultaneous and simultaneous
application support as described in Table 1 and Table 2, this Technical Report specifies a
home cabling infrastructure grading scheme as follows:
a) Grade 1 (see 4.3.2);
b) Grade 3 (see 4.3.3);
c) Grade 3S (see 4.3.4);
Any of the above infrastructure grades may be supplemented by optical fibre cabling in

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 50083 (all parts) and EN 60728 (all parts) 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.
The EN 50174 series specify the specification, planning and practices applicable to installation
of telecommunications cabling within homes.
This Technical Report describes a grading system applicable to telecommunications cabling
within homes which provides a range of implementation solutions to support both non-
simultaneous and simultaneous provision of applications incorporating:
1) a cabling structure in accordance with, but less complex than that of, EN 50173-4 and with
defined connecting hardware pin assignment for certain applications;
2) components meeting or exceeding the requirements of EN 50173-4;
3) shorter cabling channels than those specified in EN 50173-4 (simultaneous transmission of
telephony and 100BASE-T is supported by the reduced channel attenuation resulting from
the restriction of maximum channel lengths to 50 m).

4 Cabling infrastructure
4.1 Home cabling in accordance with EN 50173-4
EN 50173-4 defines two generic cabling structures (see Figure 1) to support the delivery of ICT
and BCT applications within the home:
a) between the home distributor (HD) and a telecommunications outlet (TO) for the delivery of
those services using ICT applications over balanced or optical fibre cabling;
b) between the HD and a broadcast outlet (BO) for the delivery of those services using BCT
applications over either coaxial (BCT-C) or balanced (BCT-B) cabling.
NOTE The inclusion of optical fibre to deliver BCT applications may be included in
EN 50173-4:2007/A2:201X.
For the purposes of this Technical Report, a more general term Application Outlet (AO) is used
to describe a balanced cabling outlet that supports simultaneous and non-simultaneous
provision of multiple ICT and BCT applications.

Figure 1  Home cabling for ICT and BCT applications according to EN 50173-4
CLC/TR 50173-99-2 provides additional detail regarding the implementation of BCT-C and
BCT-B cabling for applications in accordance with the EN 60728 series of standards.
Figure 1 shows the connection of the cabling to equipment at the HD. Alternatively, the cabling
may be connected directly to an external network interface (ENI) as described in EN 50173-4
which may be accommodated in the primary distribution space or home entrance space (see
EN 50174-2). In the case of BCT applications, this is more accurately described as a Home
Network Interface (HNI) as described in CLC/TR 50173-99-2.
The ENI is connected via application-specific network access cabling (see 4.4.3) to:
1) other equipment within the home (e.g. a satellite antenna);
2) other equipment within the access network;
3) within multi-tenant premises, to a building network interface within a building entrance
space.
The signal levels at HNIs are assumed to meet the requirements of EN 60728-1.
4.2 Application support
The balanced cabling for BCT applications specified in EN 50173-4 assumes a single-pair
implementation. The balanced cabling for ICT applications specified in EN 50173-4 assumes a
multi-pair implementation but is “not guaranteed to support the simultaneous transmission of
different applications … within a cable or at an interface to the generic cabling” and that “the
sharing of components by applications … may require additional performance requirements to
be applied.” This applies to simultaneous provision of two identical applications or of different
applications.
The specification of multi-pair balanced cabling to support the simultaneous provision of
multiple ICT and BCT applications requires a modification of the implementations specified in
EN 50173-4.
For example, the BCT applications providing radiofrequency transmission in the very high
frequency and ultra high frequency (VHF/UHF) bands of analogue television and terrestrial
digital video broadcast (DVB-T) use signal voltages in the mV range. In comparison, ICT
applications use signal voltages of the order of 1 V. As a result specific provisions are needed
to avoid electromagnetic disturbance on BCT applications.

In order to support ICT applications in addition to those of EN 50173-4 and to support
simultaneous provision of specific combinations of those applications (as shown in Figure 2),
this Technical Report specifies an infrastructure grading scheme utilising:
a) a cabling structure in accordance with, but less complex than that of, EN 50173-4 and with
defined connecting hardware pin assignment for certain applications;
b) components meeting or exceeding the requirements of EN 50173-4;
c) shorter cabling channels than those specified in EN 50173-4 (simultaneous transmission of
telephony and 100BASE-T is supported by the reduced channel attenuation resulting from
the restriction of maximum channel lengths to 50 m).

4.3.1 Infrastructure grades
In order to support a range of specific combinations of non-simultaneous and simultaneous
application support as described in Table 1 and Table 2, this Technical Report specifies a
home cabling infrastructure grading scheme as follows:
a) Grade 1 (see 4.3.2);
b) Grade 3 (see 4.3.3);
c) Grade 3S (see 4.3.4);
Any of the above infrastructure grades may be supplemented by optical fibre cabling in
accordance with EN 50173-4 (included in Table 1 and Table 2).

4 Cabling infrastructure
4.1 Home cabling in accordance with EN 50173-4
EN 50173-4 defines two generic cabling structures (see Figure 1) to support the delivery of ICT
and BCT applications within the home:
a) between the home distributor (HD) and a telecommunications outlet (TO) for the delivery of
those services using ICT applications over balanced or optical fibre cabling;
b) between the HD and a broadcast outlet (BO) for the delivery of those services using BCT
applications over either coaxial (BCT-C) or balanced (BCT-B) cabling.
NOTE The inclusion of optical fibre to deliver BCT applications may be included in
EN 50173-4:2007/A2:201X.
For the purposes of this Technical Report, a more general term Application Outlet (AO) is used
to describe a balanced cabling outlet that supports simultaneous and non-simultaneous
provision of multiple ICT and BCT applications.

Figure 1  Home cabling for ICT and BCT applications according to EN 50173-4
CLC/TR 50173-99-2 provides additional detail regarding the implementation of BCT-C and
BCT-B cabling for applications in accordance with the EN 60728 series of standards.
Figure 1 shows the connection of the cabling to equipment at the HD. Alternatively, the cabling
may be connected directly to an external network interface (ENI) as described in EN 50173-4
which may be accommodated in the primary distribution space or home entrance space (see
EN 50174-2). In the case of BCT applications, this is more accurately described as a Home
Network Interface (HNI) as described in CLC/TR 50173-99-2.
The ENI is connected via application-specific network access cabling (see 4.4.3) to:
1) other equipment within the home (e.g. a satellite antenna);
2) other equipment within the access network;
3) within multi-tenant premises, to a building network interface within a building entrance
space.
The signal levels at HNIs are assumed to meet the requirements of EN 60728-1.
4.2 Application support
The balanced cabling for BCT applications specified in EN 50173-4 assumes a single-pair
implementation. The balanced cabling for ICT applications specified in EN 50173-4 assumes a
multi-pair implementation but is “not guaranteed to support the simultaneous transmission of
different applications … within a cable or at an interface to the generic cabling” and that “the
sharing of components by applications … may require additional performance requirements to
be applied.” This applies to simultaneous provision of two identical applications or of different
applications.
The specification of multi-pair balanced cabling to support the simultaneous provision of
multiple ICT and BCT applications requires a modification of the implementations specified in
EN 50173-4.
For example, the BCT applications providing radiofrequency transmission in the very high
frequency and ultra high frequency (VHF/UHF) bands of analogue television and terrestrial
digital video broadcast (DVB-T) use signal voltages in the mV range. In comparison, ICT
applications use signal voltages of the order of 1 V. As a result specific provisions are needed
to avoid electromagnetic disturbance on BCT applications.

In order to support ICT applications in addition to those of EN 50173-4 and to support
simultaneous provision of specific combinations of those applications (as shown in Figure 2),
this Technical Report specifies an infrastructure grading scheme utilising:
a) a cabling structure in accordance with, but less complex than that of, EN 50173-4 and with
defined connecting hardware pin assignment for certain applications;
b) components meeting or exceeding the requirements of EN 50173-4;
c) shorter cabling channels than those specified in EN 50173-4 (simultaneous transmission of
telephony and 100BASE-T is supported by the reduced channel attenuation resulting from
the restriction of maximum channel lengths to 50 m).

4.3 Home infrastructure grading scheme
4.3.1 Infrastructure grades
In order to support a range of specific combinations of non-simultaneous and simultaneous
application support as described in Table 1 and Table 2, this Technical Report specifies a
home cabling infrastructure grading scheme as follows:
a) Grade 1 (see 4.3.2);
b) Grade 3 (see 4.3.3);
c) Grade 3S (see 4.3.4);
Any of the above infrastructure grades may be supplemented by optical fibre cabling in
accordance with EN 50173-4 (included in Table 1 and Table 2).
