19、trotechnical 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 techn
20、ical 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 part in the work. International Standards are drafted in accordance with the rules given in the ISO/I
21、EC Directives, Part 3. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requir
22、es approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Internation
23、al Standard ISO/IEC 21407 was prepared by ECMA (as ECMA-310) and was adopted, under a special “fast-track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC.ISO/IEC 21407:2001(E) vi ISO/IEC 2001 All rights r
24、eserved Introduction This International Standard is one of a series of Standards defining services and signalling procedures applicable to Private Integrated Services Networks (PISNs). The series uses ISDN concepts as developed by ITU-T and conforms to the framework of International Standards for Op
25、en Systems Interconnection as defined by ISO/IEC. This International Standard specifies the Simple Dialog (SD) supplementary service. This International Standard is based upon the practical experience of ECMA member companies and the results of their active and continuous participation in the work o
26、f ISO/IEC JTC 1, ITU-T, ETSI and other international and national standardization bodies. It represents a pragmatic and widely based consensus. There is currently no equivalent service specified by ITU-T or ETSI for public ISDN.INTERNATIONAL STANDARD ISO/IEC 21407:2001(E) ISO/IEC 2001 All rights res
27、erved 1 Information technology Telecommunications and information exchange between systems Private Integrated Services Network Specification, functional model and information flows Simple dialog supplementary service 1S c o p e This International Standard specifies the supplementary service Simple D
28、ialog (SS-SD), which is applicable to various basic services supported by Private Integrated Services Networks (PISNs). Basic services are specified in ISO/IEC 11574. Supplementary service SD enables a user to communicate with another user or application by the exchange of keypad and display informa
29、tion transparently over a PISN. Service specifications are produced in three stages, according to the method described in ETS 300 387. This International Standard contains the stage 1 and stage 2 specifications of SS-SD. The stage 1 specification (clause 6) specifies the supplementary service as see
30、n by users of PISNs. The stage 2 specification (clause 7) specifies the functional entities involved in the supplementary service and the information flows between them. 2 Conformance In order to conform to this International Standard, a stage 3 standard shall specify signalling protocols and equipm
31、ent behaviour that are capable of being used in a PISN which supports the supplementary service specified in this International Standard. This means that, to claim conformance, a stage 3 standard is required to be adequate for the support of those aspects of clause 6 (stage 1) and clause 7 (stage 2)
32、 which are relevant to the interface or equipment to which the stage 3 standard applies. 3 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendment

However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.

The Server User is the user who exclusively sends the display information whereas the user who receives that information and who is able to answer the Server User w
44、ith keypad information is called the Client User. SS-SD shall be exclusively used to convey display information and key press events. 6.1.2 Qualifications on applicability to telecommunication services This supplementary service can be used with a basic telecommunication service or independently of
45、it. 6.2 Procedures 6.2.1 Provision / withdrawal SS-SD shall be generally available to all PISN users.ISO/IEC 21407:2001(E) ISO/IEC 2001 All rights reserved 3 6.2.2 Normal procedures 6.2.2.1 Activation, deactivation and interrogation Not applicable. 6.2.2.2 Invocation and operation The supplementary
46、service Simple Dialog (SS-SD) shall be invoked between a Server User and a Client User for the exchange of display messages and key press events. For that purpose an existing call or signalling connection shall be used. If no such connection exists, and no call has to be established, a call independ
47、ent signalling connection shall be established on request of either user for that purpose. The user who initiated the call independent signalling for this reason is responsible for clearing this connection. SS-SD is invoked by the Server User upon sending display information to the connected Client
48、User. The sent display information shall be shown on the Client Usersdi s pl ay . SS-SD is invoked by the Client User upon request to send keypad information to a Server User. After that request the Client User can send key press events to the Server User. After an additional request from the Client
49、 User, no further key press events shall be conveyed to the Server User. The duration of the session is up to the service. NOTE 1 - The actions for request which have to be done by a Client User to use SS-SD (e.g. to press a specific button on Client Users TE) is out of the scope of this International Standard. The role of the Server and Client User is fixed during the lifetime of the communication. NOTE 2 - Any additional inband signalling (e.g.
