ETSI ETSI EN 305 174-2 V1.1.1 (2018-02) 6 Modal verbs terminology In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and "cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). "must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation. Introduction The increasing interaction between the different elements of the Information Communication Technology (ICT) sector (hardware, middleware, software and services) supports the concept of convergence in which: • multi-service packages can be delivered over a common infrastructure; • a variety of infrastructures is able to deliver these packages; • a single multi-service-package may be delivered over different infrastructures. As a result of this convergence, the development of new services, applications and content has resulted in: • an increased demand for bandwidth, reliability, quality and performance, with a consequent increase in the demand for power which has implications for cost and, in some cases, availability; • an associated continuous evolution of ICT equipment. It is therefore important to consider the environmental viability of all network elements necessary to deliver the required services in terms of the management of their operational aspects i.e. energy management (including energy efficiency) and the management of the End-of-Life (EoL) of the ICT equipment. NOTE: The term "environmental viability" is used while recognizing that well established treatments of "sustainability" feature three separate viability objectives (environmental, economic and social). For the purposes of this multi-part deliverable only operational aspects of environmental viability are considered. A wider approach to environmental viability takes other factors into account including the use of raw materials and avoidance of hazardous substances in the construction of infrastructure or ICT equipment- these factors are not considered. New technologies and infrastructure strategies are expected to enable operators to decrease the energy consumption, for a given level of service, of their existing and future infrastructures, thus decreasing their costs. This requires a common understanding among market participants that only standards can produce. This multi-part deliverable specifies the general engineering of various broadband infrastructures to enable the most effective energy management (and management of other resources) and the appropriate measures for EoL treatment of ICT equipment. Certain of the standards may specify requirements for interoperability. The present document is part 2 of a multi-part deliverable and specifies requirements for ICT sites within broadband deployment infrastructures. The present document has been produced by ETSI Technical Committees Access, Terminals, Transmission and Multiplexing (ATTM) and Cable in close collaboration with CENELEC, via the Installations and Cabling Co-ordination Group (ICCG).

In principle, every operator network can contain any number of each of these elements and may be connected to any number of other operator networks.

Figure 1: Network sub-systems of fixed broadband access network infrastructure Figure 2 is a technology-agnostic diagram depicting a segment of a broadband network showing the interconnection of ICT sites and base stations (BS) for mobile access networks. Each BS may provide services to a variable number of "end-use IT equipment" shown as User Equipment (UE) in Figure 2. In principle, every operator network can contain any number of each of these elements and may be connected to any number of other operator networks. Broadband provision is an enabling technology capable of supporting a reduction of global energy consumption. EXAMPLE: By providing facilities such as home working and video conferencing to reduce travel demands. For this reason, it may not be the case that the total energy consumption of broadband networks will be reduced, though the application of effective energy efficiency measures will minimize any increases due to predicted service evolution.

ETSI ETSI EN 305 174-2 V1.1.1 (2018-02) 11 The scale of reductions in energy consumption and/or improvements of energy efficiency is: • dependent on the network sub-systems; • generally greater at the design stage rather than following improvements to existing infrastructures.

Figure 2: Network sub-systems of mobile broadband access network infrastructure ICT sites comprise Operator Sites (OS) as described in clause 4.1.2 and Network Data Centres (NDC) as described in clause 4.1.3. The present document addresses OS and NDC and does not differentiate between them. It should be noted that an OS that is only connected to the core network is considered to be an NDC. The potential reductions in energy consumption and/or improvements of energy efficiency in ICT sites as described in clauses 4.1.2 and 4.1.3 are expected to be substantial but apply in only a relatively small number of locations and may prove vital where availability of power is restricted. These clearly defined premises are provided with appropriate Key Performance Indicators (KPIs) to determine relative performance levels in terms of energy efficiency. Within customer premises, it is generally the customer rather than the operator who funds the energy costs. Potential reductions in energy consumption may well be identifiable in design terms but they are generally not individually quantifiable due to the diversity of customer networks. 4.1.2 Operator Site (OS) NOTE: This is equivalent to the master head-end for a cable access network. With reference to Figure 1 and Figure 2, an OS is the network sub-system in the core network that enables the connectivity between network data centres and customer premises over which the required services can be delivered, using the access network. An OS also enables indirect connectivity between customer premises. An OS will almost invariably each serve many thousands of customer connections. Each customer connection may be comprised of multiple communication paths and serve a variety of applications. 4.1.3 Network Data Centre (NDC) NOTE 1: This is equivalent to the local head-end for a cable access network. With reference to Figure 1 and Figure 2, an NDC is a network sub-system serving the core network of one or more operators. Its functions include the storage, processing and dissemination of data as required to fulfil customer expectations

Introduction

The increasing interaction between the different elements of the Information Communication Technology (ICT) sector

(hardware, middleware, software and services) supports the concept of convergence in which:

• multi-service packages can be delivered over a common infrastructure;
• a variety of infrastructures is able to deliver these packages;

• a single multi-service-package may be delivered over different infrastructures.

As a result of this convergence, the development of new services, applications and content has resulted in:

• an increased demand for bandwidth, reliability, quality and performance, with a consequent increase in the

demand for power which has implications for cost and, in some cases, availability;

• an associated continuous evolution of ICT equipment.

It is therefore important to consider the environmental viability of all network elements necessary to deliver the required

services in terms of the management of their operational aspects i.e. energy management (including energy efficiency)

and the management of the End-of-Life (EoL) of the ICT equipment.

NOTE: The term "environmental viability" is used while recognizing that well established treatments of

"sustainability" feature three separate viability objectives (environmental, economic and social). For the

purposes of this multi-part deliverable only operational aspects of environmental viability are considered.

A wider approach to environmental viability takes other factors into account including the use of raw

materials and avoidance of hazardous substances in the construction of infrastructure or ICT equipment-

these factors are not considered.

New technologies and infrastructure strategies are expected to enable operators to decrease the energy consumption, for

a given level of service, of their existing and future infrastructures, thus decreasing their costs. This requires a common

understanding among market participants that only standards can produce.

This multi-part deliverable specifies the general engineering of various broadband infrastructures to enable the most

effective energy management (and management of other resources) and the appropriate measures for EoL treatment of

ICT equipment. Certain of the standards may specify requirements for interoperability.

The present document is part 2 of a multi-part deliverable and specifies requirements for ICT sites within broadband

deployment infrastructures.

The present document has been produced by ETSI Technical Committees Access, Terminals, Transmission and

Multiplexing (ATTM) and Cable in close collaboration with CENELEC, via the Installations and Cabling Co-ordination

Group (ICCG).

Figure 2 is a technology-agnostic diagram depicting a segment of a broadband network showing the interconnection of

ICT sites and base stations (BS) for mobile access networks. Each BS may provide services to a variable number of

"end-use IT equipment" shown as User Equipment (UE) in Figure 2.

In principle, every operator network can contain any number of each of these elements and may be connected to any

number of other operator networks.

Broadband provision is an enabling technology capable of supporting a reduction of global energy consumption.

EXAMPLE: By providing facilities such as home working and video conferencing to reduce travel demands.

For this reason, it may not be the case that the total energy consumption of broadband networks will be reduced, though

the application of effective energy efficiency measures will minimize any increases due to predicted service evolution.

11 ETSI EN 305 174-2 V1.1.1 (2018-02)

The scale of reductions in energy consumption and/or improvements of energy efficiency is:

• dependent on the network sub-systems;

• generally greater at the design stage rather than following improvements to existing infrastructures.

ICT sites comprise Operator Sites (OS) as described in clause 4.1.2 and Network Data Centres (NDC) as described in

clause 4.1.3. The present document addresses OS and NDC and does not differentiate between them. It should be noted

that an OS that is only connected to the core network is considered to be an NDC.

The potential reductions in energy consumption and/or improvements of energy efficiency in ICT sites as described in

clauses 4.1.2 and 4.1.3 are expected to be substantial but apply in only a relatively small number of locations and may

prove vital where availability of power is restricted. These clearly defined premises are provided with appropriate Key

Performance Indicators (KPIs) to determine relative performance levels in terms of energy efficiency.

Within customer premises, it is generally the customer rather than the operator who funds the energy costs. Potential

reductions in energy consumption may well be identifiable in design terms but they are generally not individually

quantifiable due to the diversity of customer networks.
4.1.2 Operator Site (OS)
NOTE: This is equivalent to the master head-end for a cable access network.

With reference to Figure 1 and Figure 2, an OS is the network sub-system in the core network that enables the

connectivity between network data centres and customer premises over which the required services can be delivered,

using the access network. An OS also enables indirect connectivity between customer premises. An OS will almost

invariably each serve many thousands of customer connections. Each customer connection may be comprised of

multiple communication paths and serve a variety of applications.

Introduction

The increasing interaction between the different elements of the Information Communication Technology (ICT) sector

(hardware, middleware, software and services) supports the concept of convergence in which:

• multi-service packages can be delivered over a common infrastructure;
• a variety of infrastructures is able to deliver these packages;

• a single multi-service-package may be delivered over different infrastructures.

As a result of this convergence, the development of new services, applications and content has resulted in:

• an increased demand for bandwidth, reliability, quality and performance, with a consequent increase in the

demand for power which has implications for cost and, in some cases, availability;

• an associated continuous evolution of ICT equipment.

It is therefore important to consider the environmental viability of all network elements necessary to deliver the required

services in terms of the management of their operational aspects i.e. energy management (including energy efficiency)

and the management of the End-of-Life (EoL) of the ICT equipment.

NOTE: The term "environmental viability" is used while recognizing that well established treatments of

"sustainability" feature three separate viability objectives (environmental, economic and social). For the

purposes of this multi-part deliverable only operational aspects of environmental viability are considered.

A wider approach to environmental viability takes other factors into account including the use of raw

materials and avoidance of hazardous substances in the construction of infrastructure or ICT equipment-

these factors are not considered.

New technologies and infrastructure strategies are expected to enable operators to decrease the energy consumption, for

a given level of service, of their existing and future infrastructures, thus decreasing their costs. This requires a common

understanding among market participants that only standards can produce.

This multi-part deliverable specifies the general engineering of various broadband infrastructures to enable the most

effective energy management (and management of other resources) and the appropriate measures for EoL treatment of

ICT equipment. Certain of the standards may specify requirements for interoperability.

The present document is part 2 of a multi-part deliverable and specifies requirements for ICT sites within broadband

deployment infrastructures.

The present document has been produced by ETSI Technical Committees Access, Terminals, Transmission and

Multiplexing (ATTM) and Cable in close collaboration with CENELEC, via the Installations and Cabling Co-ordination

Group (ICCG).

Figure 2 is a technology-agnostic diagram depicting a segment of a broadband network showing the interconnection of

ICT sites and base stations (BS) for mobile access networks. Each BS may provide services to a variable number of

"end-use IT equipment" shown as User Equipment (UE) in Figure 2.

In principle, every operator network can contain any number of each of these elements and may be connected to any

number of other operator networks.

Broadband provision is an enabling technology capable of supporting a reduction of global energy consumption.

EXAMPLE: By providing facilities such as home working and video conferencing to reduce travel demands.

For this reason, it may not be the case that the total energy consumption of broadband networks will be reduced, though

the application of effective energy efficiency measures will minimize any increases due to predicted service evolution.

The scale of reductions in energy consumption and/or improvements of energy efficiency is:

• dependent on the network sub-systems;

• generally greater at the design stage rather than following improvements to existing infrastructures.

ICT sites comprise Operator Sites (OS) as described in clause 4.1.2 and Network Data Centres (NDC) as described in

clause 4.1.3. The present document addresses OS and NDC and does not differentiate between them. It should be noted

that an OS that is only connected to the core network is considered to be an NDC.

The potential reductions in energy consumption and/or improvements of energy efficiency in ICT sites as described in

clauses 4.1.2 and 4.1.3 are expected to be substantial but apply in only a relatively small number of locations and may

prove vital where availability of power is restricted. These clearly defined premises are provided with appropriate Key

Performance Indicators (KPIs) to determine relative performance levels in terms of energy efficiency.

Within customer premises, it is generally the customer rather than the operator who funds the energy costs. Potential

reductions in energy consumption may well be identifiable in design terms but they are generally not individually

quantifiable due to the diversity of customer networks.
4.1.2 Operator Site (OS)
NOTE: This is equivalent to the master head-end for a cable access network.

With reference to Figure 1 and Figure 2, an OS is the network sub-system in the core network that enables the

connectivity between network data centres and customer premises over which the required services can be delivered,

using the access network. An OS also enables indirect connectivity between customer premises. An OS will almost

invariably each serve many thousands of customer connections. Each customer connection may be comprised of
