Title Interoperability framework requirements specification for service to the home (IFRS)
Project Number 22584
Abstract/Scope This CWA contains a specification of an Interoperability Requirements Framework, specifying seven levels of interoperability, based on four groups of interoperability steps specified by five types of interaction, plus a methodology based on conformance clauses for satisfying requirements related to the claimed level of interoperability of devices installed in a Home and Building Electronic System (HBES, HES). It is applicable to installations of a single type of HBES, or that interconnect two or more dissimilar HBESs. Within a HBES of a single type any of its capabilities for service, applications and connectivity topology can be used. Interconnection technologies used to interconnect dissimilar HBES are similarly unconstrained. For applicable installations, the scope of its provisions applies to: the connection of devices to the various communications services to enable them to communicate end-to-end across internetworked media; the processes of discovery by which devices find out about each other and configuration to associate them with each other; and the generic aspects of application operation; and management. This CWA is not applicable to the interoperability required between devices to implement specific applications, such as heating or lighting control, energy management, or entertainment. The interoperability requirements defined in this CWA are necessary for such application interoperability but not sufficient. This CWA does not define how measurements are made; nor the algorithms that receive, process and respond to them; nor the interaction between users, service providers, and the HBES application(s). This is the responsibility of experts and organisations that specialise in particular application domains. The users of the CWA will be installers, system integrators, application designers and service providers of HBES applications and services. It will allow them to select devices and their functionality, including end-points and gateways and software applications hosted in them, that may be deployed in customer premises. Given specific application functional requirements, which are, as noted above, themselves a separate, vertical, collection of interoperability rules, the CWA will allow its users to select specific products consistent with their application objectives. Products can be substituted for each other with expectations that the system and its applications will continue to perform their specified function being set by the level of interoperability that is claimed. The CWA is applied by completion by its implementer of PICS proformas and related PIXIT proformas for a device. The PICS/PIXIT method was standardized by ISO/JTC1/SC21 as part of the means by which conformance was claimed to the protocols and services of the Open Systems Interconnection (OSI) family of standards, and has been refined by ETSI subsequently. Consistent with the CWA, the proformas represent a voluntary disclosure of information. Their status and acceptability will be enhanced by a certification issued by a test house that has verified the interoperability claims that the PICS contains. The PIXIT provides information to the test house to instruct testers on test configuration and any extra information required to place the device in the correct state for individual claims to be verified. Devices and services interacting to form new applications across application and system domains may result in multiple applications or services requiring access and control of individual devices and objects in the premises. Clusters of applications will intersect and will have to coexist. Therefore this CWA will address the requirements for safety, security and priority of access and control. (...)

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved


(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat


(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level


(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement


(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn


(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
