The present document aims at further simplifying end-user access to ICT devices, services, and applications by providing recommended terms for basic and commonly-used ICT-related objects and activities, notably those terms that end users are commonly exposed to. Recommended terms are provided in 27 languages: Bulgarian, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hungarian, Icelandic , Irish, Italian, Latvian, Lithuanian, Maltese, Norwegian, Polish, Portuguese, Rhaeto Romance, Romanian, Slovak, Slovenian, Spanish, and Swedish (as spoken in their respective European countries).
The recommended terms apply to mobile ICT devices and mobile applications (whether they are standalone or provide access to related services) commonly found in mobile ICT devices. Though developed in a mobile ICT context, most of the recommended terms are applicable to both mobile and fixed-network devices, services, and applications. The recommended terms are applicable to the User Interface (UI) design for a product as well as that of any user documentation accompanying it.
User requirements and, when available, industry-originated documents as well as results of previous standardization work have been considered and integrated in the present document, providing implementation-oriented guidance.
Wherever possible, a Design-for-All approach has been adopted, taking functional abilities of users, including elderly users and users with cognitive, physical, or sensory limitations into account.
The present document provides recommendations for terms that may be used by those who consider supporting the languages addressed in future products and services. It does not provide design guidance, nor does it intend to restrict the ability of market players to further improve and develop their devices and services. Neither does it intend to limit their options to trademark user interface elements or profile the user experience of brand-specific user interface implementations as a competitive edge.

APIs, etc. TTCN-3 is not restricted to conformance testing and can be used for many other kinds of testing including
interoperability, robustness, regression, system and integration testing. The specification of test suites for physical layer
protocols is outside the scope of the present document.
TTCN-3 packages are intended to define additional TTCN-3 concepts, which are not mandatory as concepts in the
TTCN-3 core language, but which are optional as part of a package which is suited for dedicated applications and/or
usages of TTCN-3.
This package defines types for behaviour definitions in TTCN-3.
While the design of TTCN-3 package has taken into account the consistency of a combined usage of the core language
with a number of packages, the concrete usages and guidelines for this package in combination with other packages is
outside the scope of the present document.

The present document specifies the control interfaces for TTCN-3 test system implementations. The TTCN-3 Control
Interfaces provide a standardized adaptation for management, test component handling and encoding/decoding of a test
system to a particular test platform. The present document defines the interfaces as a set of operations independent of a
target language.
The interfaces are defined to be compatible with the TTCN-3 standard (see clause 2). The interface definition uses the
CORBA Interface Definition Language (IDL) to specify the TCI completely. Clauses 8, 9, 10, 11 and 12 present
language mappings for this abstract specification to the target languages Java™, ANSI C, C++, XML and C#.
A summary of the IDL-based interface specification is provided in annex A.
NOTE: Java™ is the trade name of a programming language developed by Oracle Corporation. This information
is given for the convenience of users of the present document and does not constitute an endorsement by
ETSI of the programming language named. Equivalent programming languages may be used if they can
be shown to lead to the same results.

The present document defines the Extended TRI package of TTCN-3. TTCN-3 can be used for the specification of all types of reactive system tests over a variety of communication ports. Typical areas of application are protocol testing (including mobile and Internet protocols), service testing (including supplementary services), module testing, testing of CORBA based platforms, APIs, etc. TTCN-3 is not restricted to conformance testing and can be used for many other kinds of testing including interoperability, robustness, regression, system and integration testing. The specification of test suites for physical layer protocols is outside the scope of the present document. TTCN-3 packages are intended to define additional TTCN-3 concepts, which are not mandatory as concepts in the TTCN-3 core language or in its interfaces TRI and TCI, but which are optional as part of a package which is suited for dedicated applications and/or usages of TTCN-3. This package defines a more efficient handling of software values by a version of TRI, that does not use binary encoded messages for the communication with the SUT, but uses the values as they are; meaning e.g. that software objects or serialized data can be passed directly between the SUT and the TE. While the design of TTCN-3 package has taken into account the consistency of a combined usage of the core language with a number of packages, the concrete usages of and guidelines for this package in combination with other packages is outside the scope of the present document.

The present document aims at further simplifying end-user access to ICT devices, services, and applications by providing
recommended terms for basic and commonly-used ICT-related objects and activities, limited to those terms that end
users are commonly exposed to. Recommended terms are provided in five languages: English, French, German, Italian,
and Spanish (as spoken in their respective European countries).
The recommended terms apply to mobile ICT devices and mobile applications (whether they are standalone or whether
they provide access to related services) commonly found in mobile ICT devices (most of the recommended terms are
applicable to both mobile and stationary devices, services, and applications). The recommended terms are applicable to
the User Interface (UI) design for a product as well as that of any user documentation accompanying it.
User requirements and available results of standardization work have been considered and integrated in the present document,
providing implementation-oriented guidance. Wherever possible, a Design-for-All approach has been adopted,
taking functional abilities of users, including elderly users and users with cognitive, physical, or sensory limitations into
account.
The present document does not provide design guidance, nor does it intend to restrict the ability of market players to
further improve and develop their terminals and services. Neither does it intend to limit their options to trademark user
interface elements or profile the user experience of brand-specific user interface implementations as a competitive edge.

The present document defines the metrics and measurement methods for the energy efficiency of functional components
of NFV environment. The NFV functional components include Virtualised Network Functions (VNFs) and NFV
Infrastructure (NFVI) defined in NFV architecture framework as described in ETSI GS NFV 002 [i.1]. Management
and Orchestration (MANO) is not included as system under test, but will be eventually taken as test environment.
The measurement method described in the present document is intended to be used to assess and compare the energy
efficiency of same functional components independently in lab testing and pre-deployment testing. Energy efficiency of
co-located VNFs sharing same platform resources cannot be compared using the defined method in present document.
The scope of the document is not to define measurement method in operational NFV environment.
The present document is intended to define common energy efficiency measurement methods for NFV environments,
not try to cover all different types of VNFs (e.g. firewall, gateway, etc.), but it provides the basis to make extensible
definition.

The present document specifies the requirements for a Global KPI for energy management (designated KPIEP) and its
underpinning Objective KPI for energy consumption addressing the following objectives for the cable operator access
networks of broadband deployment:
• energy consumption;
• renewable energy.
The requirements are mapped to the concepts of ETSI EN 305 200-1 [i.5].
Energy management of cable access networks comprises a number of independent layers. The present document
addresses performance of infrastructures that supports the normal function of hosted ICT equipment within the cable
access network (e.g. power distribution, environmental control, security and safety). The present document does not
address other layers such as performance of ICT equipment itself, performance of usage of available processing power,
and layers related to final service delivered (e.g. processing power required per itemized outcome) or overlay layers
(e.g. final energy required per itemized outcome).
The environmental impact and management of different energy sources are outside the scope of the present document.
Within the present document:
• clause 4 describes the energy parameters for cable access networks employing DOCSIS 3.0 and/or
DOCSIS 3.1 together with inclusions/exclusions of different energy sources;
• clause 5 specifies the requirements for measurement, calculation, classification and reporting of KPIEP.
