and their connection to external cabling in order to support the BCT applications of Annex F of

EN 50173-1 and in accordance with the EN 60728 series of standards.

The delivery of BCT applications to support CATV or MATV/SMATV networks in accordance with the

EN 60728 series of standards to the home, independent of the premises that accommodate the home, is

described in terms of:
a) the functional elements required;

Figure 1 — Structure of generic cabling for BCT applications (CATV)
Figure 2 — Structure of generic cabling for BCT applications (MATV/SMATV)
4.3.2 External cabling subsystems

For CATV cable networks, the signals received by remote and/or local headends are delivered through

super trunk feeder cables to hub headends. The signals are then subdivided and delivered to distribution

points (DPs) via trunk feeder cables. A branch feeder cable connects each home network interface (HNI)

or building network interface (BNI) (in the case of multi dwelling premises) to a DP.

For MATV/SMATV cable networks the signals received by the antenna system are fed to the headend. A

branch feeder cable connects each home network interface (HNI) or building network interface (BNI) (in

the case of multi dwelling premises) to the headend.
4.3.3 Building backbone subsystem

Where the premises served by the external cabling subsystems accommodate multiple homes, the BNI is

connected to the HNI either via:
a) a subscriber feeder cable;

b) a spur feeder cable to a floor distributor and then a subscriber feeder cable.

CLC/TR 50173-99-2:2020
4.3.4 Home cabling subsystem

The signals delivered at the HNI are fed to the terminal equipment connected to the system outlet (SO)

through the home network comprising cabling and optional splitter/amplifier equipment.

The home cabling subsystem has different configurations depending on the extension and on the

applications made available at the home premises (see Figure 3). Various types of home networking for

home premises are described in EN 60728-1-1.

This technical report describes the delivery of the signals from the HNI to the SO using cabling in

accordance with EN 50173-4.

NOTE The home cabling subsystem defined and described in EN 50173-4 forms part of the home cabling

subsystem as shown in Figure 1 and Figure 2.

4.4 Accommodation of functional elements
4.4.1 Headend and antenna systems

The headend systems for CATV cable networks are typically located in equipment rooms that provide all

the facilities (space, power, environmental control etc.) for passive components, active devices and

connection to local and/or remote antenna systems.

The headend systems for MATV/SMATV cable networks may be located in a small room or a dedicated

space, where all the facilities (space, power, etc.) for passive components, active devices and connection

to the antenna system are provided. Examples of headend and requirements for headend equipment are

described in EN 60728-5.
The installation of equipment shall be in accordance with EN 60728-11.
4.4.2 Building network

Within multi dwelling premises, the BNI is typically located in equipment rooms that should provide all the

facilities (space, power, environmental control etc.) for passive components and active devices. Each

equipment room should have direct access to the relevant cabling subsystems.

Where the functional elements share the same space as the distributors of generic cabling systems in

accordance with the EN 50173 series of standards; the requirements for the accommodation of

distributors are specified in EN 50173-1.

Requirements for building entrance facilities are specified in the EN 50174 series of standards.

NOTE The location of BNI and building entrance facilities which are provided can be subject to national or local

regulations.
4.4.3 Pathways and pathway systems
See the EN 50174 series of standards.
4.4.4 HNI

The use of generic cabling in accordance with EN 50173-4 to support BCT applications in accordance

with the EN 60728 series of standards (CATV or MATV/SMATV networks) requires the HNI to be located

within the home distributor (HD).
The requirements for the HD are specified in EN 50173-4.
The requirements for the accommodation of the HD are specified in EN 50174-2.
Requirements for home entrance facilities are specified in the EN 50174-2.

NOTE The location of HNI and home entrance facilities which are provided can be subject to national or local

regulations.
