0 ISO/IEC ISO/IEC ISP 11185-1: 1994(E) Foreword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized System for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take patt in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTCl. In addition to developing International Standards, lSO/IEC JTCI has created a Special Group on Functional Standardization for the elaboration of International Standardized Profiles. An International Standardized Profile is an internationally agreed, harmonized document which identifies a Standard or group of Standards, together with Options and Parameters, necessary to accomplish a function or set of functions. Draft International Standardized Profiles are circulated to national bodies for voting. Publication as an International Standardized Profile requires approval by at least 75% of the national bodies casting a vote. International Standardized Profile ISO/IEC ISP 11185-1 was prepared with the collaboration of - OSI Asia-Oceania Workshop (AOW); - European Workshop for Open Systems (EWOS); - Open Systems Environment Implementors Workshop (OIW). This International Standardized Profile ISO/IEC ISP 11185 forms an International Register of information objects in accordance with the procedures for the Operation of OSI Registration Authorities laid down in ISO/IEC 9834. lt is issued in Parts, with additional Parts being issued as further entries are added to the register.

ISO/IEC ISP 11185-1: 1994(E) 0 ISO/IEC Introduction This International Standardized Profile ISO/IEC ISP 11185 is defined within the context of Functional Standardization, in accordance with the principles specified in ISO/IEC TR 10000, “Framework and Taxonomy of International Standardized Profiles”. The context of Functional Standardization is one patt of the Overall field of Information Technology (IT) standardization activities, covering base Standards, profiles and registration mechanisms. The Open Systems Interconnection (OSI) Standard ISO 9040 for the Virtual Terminal Basic Class Service identifies a requirement for an International Register of VT Control Object type definitions. Procedures for the Operation of this International Register are laid down in lSO/IEC 9834-5. This International Standardized Profile provides this register. The individual entries in this register constitute Interchange Format and Representation Profiles (F-Profiles) within the framework of lSO/IEC TR 10000. This patt of lSO/IEC ISP 11185 was developed in close cooperation between the three Regional OSI Workshops, namely the OSE Implementors Workshop (OW) of the United States, the European Workshop for Open Systems (EWOS) and the OSI Asia- Oceania Workshop (AOW). lt was developed under the editorship of EWOS from a control Object specification contained in the OIW Stable Implementation Agreements, Version 3 (December 1989). The text is harmonized between these three Workshops and it has been ratified by the plenary assemblies of each Workshop. SIST EN ISP 11185-1:1997

INTERNATIONAL STANDARDIZED PROFILE @ ‘So”EC ISO/IEC ISP 11185-1: 1994(E) Information technology - International Standardized Profiles FVT2nn - Virtual Terminal Basic Class - Register of control Object type definitions - Part 1: FVT211, FVT212 - Sequenced and Unsequenced Application Control Objects 1 Scope 1 .l General The concept of Profiles for OSI, and the structure of the International Standardized Profiles that document them, are defined in lSO/lEC TR 10000-1. Such Profiles are divided into a number of different classes and sub-classes. Two of these classes contain sub-classes comprising functions of the Virtual Terminal Basic Class Service and Protocol specified in the base Standards ISO 9040 and ISO 9041. These are the Application Profiles (A-Profiles) and the Interchange Format and Representation Profiles (F-Profiles). The relationship between A-Profiles and F-Profiles is described in 7.3.2 of ISO/IEC TR 10000-1 and is as follows. Application Layer base Standards require, implicitly or explicitly, the structure of information carried or referenced by them to be specified for each instance of communication. lt is the purpose of F-Profiles to specify such information structures. Particular functional requirements may then be met by the combination of an A-Profile with one or more F- Profiles. Establishment of a VT-association involves the selection by negotiation of a particular Virtual Terminal Environment Profile (VTE-profile), and of particular values for any arguments of that VTE-Profile. The VTE-Profile specification, and possibly also the values of certain VTE-Profile arguments, may in turn reference the definitions of VT control Object types and assignment types. These VTE-profiles, control Object types and assignment types are thus information structures that require explicit reference within the VT protocol. Particular instances of these structures are fully defined within the base Standards, but the base Standards also provide for further instances to be defined by registration. Esch registered instance constitutes an F-Profile within the framework of ISO/IEC TR 10000. The Virtual Terminal Basic Class Service and Protocol may be used to realise a wide range of distinct functions. Particular functions may be realised through the selection of appropriate VT functional units, F-Profiles and other VTE- Profile argument values. The specification of the selection required to realise a particular function and to promote interoperability constitutes a Virtual Terminal A-Profile within the framework of ISO/IEC TR 10000. The three International Registers of VT information structures and the specifications of VT Application Profiles are each published as a separate multi-part ISP as follows: - ISO/IEC ISP 11184 is the Register of VTE-profiles; - ISO/IEC ISP 11185 is the Register of control Object type definitions; - ISO/IEC ISP 11186 is the Register of assignment-type definitions; - ISO/IEC ISP 11187 contains the specifications of VT Application Profiles. This part of ISO/IEC ISP 11185 contains the definitions of two control Object types that may be used to convey Signals for device control from an application to a terminal. One is used to convey these Signals in sequence with other data. The other is used to convey these Signals urgently when there is no requirement to maintain a sequence Order with other data. 1.2 Position within the taxonomy The taxonomy of International Standardized Profiles for OSI is laid down in ISO/IEC TR 10000-2. Within the classification scheme of this taxonomy, the OSI Profiles specified in this International Standardized Profile are in the Virtual Terminal Registered Object sub-class of the class of Interchange Format and Representation Profiles. A Profile within this subclass has a Profile identifier of the form FvTabc, where abc is a structured numerical identifier that identifies the Position of the Profile within each of the three levels of subdivision of the subclass. The values of a and b are Single digits but c is an integer that is not necessarily a Single digit. In principle the ISO Virtual Terminal model allows for multiple classes of Operation, although at the time of publication of this International Standardized Profile only the Basic Class has been defined. The value of the identifier component a 1 SIST EN ISP 11185-1:1997

ISO/IEC ISP 1-I 185-1: 1994(E) 0 ISO/IEC distinguishes between distinct types of information Object as follows: Control objects (COS) form one of the types of information Object that may be present in the @CA. This is illustrated in figure 1, in which CO-I, CO-2, . . . CO-n represent a number - a= 1 for Basic Class VTE-profiles; of different control objects present in the CCA. The negotiation during establishment of a VT-association will - a= 2 for Basic Class Control Objects; determine whether or not these will include control objects of either or both of the types whose definitions are given in this - a= 3 for Basic Class Assignment Types. part of ISO/IEC ISP 11185. Values of a greater than 3 are reserved for future developments. This International Standardized Profile lSO/lEC ISP 11185 contains the specifications of the Profiles with identifiers of the form FVT2bc. For this form of identifier, the component b distinguishes between the five major classifications of Basic Class Control Objects as follows: - b= 1 for Miscellaneous Control Objects; - b = 2 for Field Entry Instruction Control Objects; - b = 3 for Field Entry Pilot Control Objects; - b = 4 for Reference Information Objects; - b = 5 for Termination Conditions Control Objects. Esch of these classifications corresponds to a sub-register under the procedures of ISO/IEC 9834-5. The identifier component c is the serial number of the control Object type in the appropriate sub-register. Values of b greater than 5 are reserved for new classifications of Basic Class Control Objects that may be defined in future amendments to ISO 9040. This part of lSO/IEC ISP 11185 contains the definitions of the Miscellaneous Control Object types with the Profile identifiers FVT211 - Sequenced Application Control Object; FVT212 - Unsequenced Application Control Object, 1.3 Scenario The specification of the Virtual Terminal Service is given in ISO 9040. lt is based on a model in which two VT-users communicate by means of a shared Conceptual Communication Area (CCA) that is a conceptual part of the VT service-provider. Information exchange is modelled by one VT-user updating the content of the CCA and the changed state of the CCA then being made accessible to the peer VT-User. VT service-provider Conceptual Communbation Area Figure 1 - Control objects in the VT Service model The CCA is structured by the Virtual Terminal Service into a number of components. For a control Object the Data Structure Definition (DSD) component of the CCA contains the Syntax of its information content, including the range of possible values and the permitted update operations. The current value of its information content is contained in the Control, Signal and Status Stare (CSS) component. Updates to the current value take place through the issue of VT Service primitives by one VT-user to the service-provider. Changes of state of the CCA are made accessible through the issue of VT Service primitives by the service-provider to the peer VT-User. By clause 14 of ISO 9040, COS enable VT-users to handle control information related to virtual terminal functions and to real devices. This control is exercised by the VT-users through semantics associated with the information content and with the update operations of the CO. Definition of the semantics, or specification of the Source of the semantics if the semantic details are not fully prescribed, forms patt of the registered definition of the CO. These semantics are not however of concern to the VT service-provider itself. The DSD will contain an ANI Object identifier that identifies the registered definition, but the VT service-provider merely acts as a repository of this value. lt is only the VT-user that requires knowledge of the registered definition. NOTE 1 - The VTE-Parameter values that determine the Syntax of the information content may not be negotiated explicitly during association establishment. Moreover, in the case of non-parametric COS these values do not determine the details of the Syntax. Such values and details form part of the registered definition of the CO. Since the VT service-provider is not required to have knowledge of this registered definition, in principle the VT-users provide the VT service-provider with such information through local management procedures. Whether or not this is necessary in practice depends on the configuration of the implernentations concerned. The control Object types defined in this part of lSO/IEC ISP 11185 assume an asymmetry between the two communicating,end Systems. One end System is assumed to have a terminal role and to contain devices for the input and display of data and for signalling. These devices form part of the VT-user component of that end System. The other end System is assumed to have an application role and to contain an application package that the terminal end System desires to access. This asymmetry may, but need not, be recognised by the VT Service; Provision for such recognition exists only in an S-mode VT-association. Control objects of the types defined in this part of ISO/IEC ISP 11185 are used to enable the application package to issue control Signals to the devices of the terminal end System. The Virtual Terminal Protocol specification given in ISO 9041- 1 models the VT service-provider in terms of protocol exchange between two Virtual Terminal Protocol Machines (VTPMs), each with its own CCA. The CCA of each VTPM is updated both by Service primitives received from its own VT- user and by protocol elements received from the peer VTPM. Corresponding Service primitives and protocol elements are issued by the VTPM to provide notification of changes to the SIST EN ISP 11185-1:1997

This is illustrated in figure 2 in the context of the asymmetric end Systems described above. The control Object type definitions given in this part of ISO/IEC ISP 11185 are expressed in terms of this model. For certain types of control Object the abstract Syntax of ISO 9041-1 does not provide a complete specification for the representation of CO update operations. This arises where the abstract Syntax of ISO 9041-1 makes use of an ASN.l any type, or where symbolic values have to be encoded in terms of an ASN.1 integer type. Control Object type definitions are required by ISO/IEC 9834-5 to provide the necessary refinement of the abstract Syntax. NOTE 2 - Since an abstract Syntax is made available for use through its inclusion in a presentation context, and since the Presentation service-provider has no knowledge of control Object type definitions, in principle the VT-users provide the Presentation service-provider with these refinements to the abstract Syntax through local management procedures. Whether or not this is necessary in practice depends on the configuration of the implernentations concerned. 2 Normative references The following documents contain provisions which, through reference in this text, constitute provisions of this part of ISO/IEC ISP 11185.
