15、(E) o ISO/IEC Foreword IS0 (the International Organization for Standardization) and IEC (the Inter- national Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of International Standard
16、s through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical corn- mittees collaborate in fields of mutual interest. Other international organ- izations, governmental and non-governmental, in liaison with IS0 an
17、d I EC, also take part in the work. In the field of information technology, IS0 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 vot- ing. Publication as an International
18、Standard requires approval by at least 75 % of the national bodies casting a vote. International Standard ISOA EC I371 4 was prepared by Joint Technical Committee ISOIIEC JTC 1, Information technology, Subcommittee SC 18, Document processing and related communication. Annexes A and B of this Interna
19、tional Standard are for information only. iv o ISO/IEC ISO/IEC 1371 4:1995(E) Introduction Voice messaging systems allow telephone users to leave recorded messages for people who are unable to answer their telephone, either because they are absent or busy, or because they are currently engaged on an
20、other telephone call. This is commonly referred to as call answering. Voice messaging systems can also allow users to send voice messages directly, without accessing call answering. Voice messaging systems are increasingly available and accessed from homes and offices, as well as from public and mob
21、ile telephones. With callers leaving messages on many different systems and subscribers increasingly likely to have mailboxes on more than one system, there is a need for users to have a common interface for the basic features of voice messaging systems. Experience has shown that consistent and pred
22、ictable human interfaces benefit users. Benefits can include faster learning, greater productivity, and greater satisfaction. Consistent human interfaces can also benefit an industry by promoting greater acceptance for products and services. The DTMF interface provides a highly restricted user inter
23、face, as there are only 12 different keys available for input, and output is via an audio channel, whose performance is constrained by speed and users limited short-term memory capabilities. For these reasons, users are particularly likely to benefit from common user interface features both within a
24、nd across different voice messaging systems they encounter, as they can learn a common set of input and output protocols, which will rnaximise the efficiency and usability of these interfaces. This International Standard includes only some of the features in DTMF-controlled systems used for voice me
25、ssaging (see clauses 5, 6, 7, 8, and 9, following) but, as described later in this International Standard (see clause 1 and Figure 1) there exist large areas of commonality with important functions in other telephone-based (i.e., interactive voice response) systems and services. Many of the user int
26、erface features specified in this International Standard will be usable for and implemented in other interactive voice response applications. Annex B of this standard summarises the subset of the telephone user interface features described in the body of this standard that are generally applicable i
27、n DTMF-controlled telephone-based interfaces beyond voice messaging. V ._ INTERNATIONAL STANDARD 0 ISO/IEC ISO/IEC 137 14: 1995( E) Information technology - Document processing and related communication - User interface to telephone- based services - Voice messaging applications 1 Scope This Interna
28、tional Standard will provide users of voice messaging systems with a consistent mode of interaction in a way that is independent of the underlying system implementations. The interface is based on a set of design guidelines annexed to this International Standard. The interface supports the ability o
29、f all users described in the user-system model (see Figure 2) to access the features of voice messaging systems. In a call answering application, the interface allows callers to leave messages from all types of telephones. It also allows callers to access additional features through the use of DTMF
30、devices. In the voice mail application, through the use of DTMF devices, the interface allows subscribers to send and receive voice messages, and to manage stored data, and allows non-subscribers to leave voice messages for subscribers. This International Standard addresses the following six functio
31、nal areas: a caller leaving a voice message, when the call is answered by a voice messaging system call answering facility; a caller leaving a voice message, when a message is sent to a subscriber by a subscriber or non- subscriber through direct messaging; a subscriber listening to and processing v
32、oice messages received; a subscriber creating and sending voice messages through the voice mail application; the sending and receiving of messages via voice message delivery applications; and the use of voice bulletin boards. 9 Within these functional areas, only certain features are defined in this
33、 International Standard. However, standard-conforming systems are not limited to these functions and features, and this International Standard does not preclude alternative methods of invoking features specified in this International Standard, providing that these alternatives do not conflict with t
34、he standard interface specified for other features covered in this International Standard. In this International Standard, the direct messaging functional area is covered in the clause specifying the call answering application. In addition, this International Standard specifies two requirements to b
35、e satisfied in all voice messaging contexts, not just the application contexts specified earlier in this clause: the use of # as a delimiter (see 5.6.1), and the access to and presence of the control menu (see 5.6.2) and its associated functionality. This International Standard does not address the
36、user/system interface for administrators, who have responsibility for the management and maintenance of the voice messaging system. This International Standard also does not address the proactive method, if any, employed by a voice messaging system to notify a user that a voice mailbox contains a me
37、ssage. Notification is, at present, typically achieved by a message waiting light, a distinctive dial-tone, or a pager device. 1 ISO/I EC 137 14: 1995 (E) o ISO/IEC Access Messaging This International Standard does not specify a non-DTMF user interface for Integrated Services Digital Network (ISDN)
38、terminal access to voice messaging applications; however, if a users ISDN terminal or switching equipment has the capability for full simulation of DTMF tones after call connection, the user interface specified in this International Standard will operate a conforming voice messaging system.

43、rm to clause 5. Additionally, the user interface to a conforming call answering application shall conform to clause 6; the user interface to a conforming voice mail application shall conform to clause 7; the user interface to a conforming voice bulletin board application shall conform to clause 8; a
44、nd the user interface to a conforming voice message delivery application shall conform to clause 9. The only requirement for conformance with respect to callers using non-DTMF telephones is as specified in 6.1. A conforming system may also provide one or more additional, alternative user interfaces
45、which are inconsistent with any or all of clauses 5, 7, 8, and 9, but only to logged-in subscribers who have chosen that alternative interface. The interface specified in this International Standard shall be the default configuration of the system when supplied. A voice messaging system in which the
46、 call answering application conforms to clauses 5 i3 6, but in which the other voice messaging applications covered by the scope of this International Standard do not conform may be described as having a conforming call answering application. Throughout clauses 5, 6, 7, 8, and 9, the following conve
47、ntions are used to indicate levels of conformance required of compliant systems: Mandatory/resewed: Conforming systems shall have this function/feature and the function/feature shall be accessible in (at least) the way specified. Optional/resewed: Conforming systems may or may not have this function
48、/feature. If the function/feature is offered, it shall be accessible in (at least) the way specified. If the function/feature is not offered the access mechanism specified shall not be used to access any other function/feature. OptionaVnot reserved: Conforming systems may or may not have this functi
49、on/feature. If the functiodfeature is offered in the system state and menu level concerned, it shall be accessible in (at least) the way specified at the menu concerned. If the functiodfeature is not offered, the access mechanism may be used to access another function/feature. Note: In describing the effect of key-presses in a conforming interface, this International Standard uses a simple declarative mode (e.g. “the play command causes playback.“). The normative content of the standard is carried by the specification of “mandatory/reserved“, “optional/reserved“ and IoptionaVnot reserved
