19、8L 988 Page 7 ETR 079:1993 Foreword This ETSI Technical Report (ETR) has been produced by the European Computer Manufacturers Association (ECMA) on behalf of its members and those of the European Telecommunications Standards Institute (ETSI). This ETR provides information on supplementary services p
20、rovided by Private Telecommunication Networks (PTNs). Many of these services will be the subject of future European standardisation. This ETR is based on the ISDN concepts as developed by CCITT and is also within the framework of standards for open systems interconnection as defined by ISO. The ETR
21、is based upon the practical experience of ECMA member companies and the results of their active and continuous participation in the work of ISO, CCIT, ETSI and other international and national standardisation bodies. It represents a pragmatic and widely based consensus. This ETR is a contribution to
22、 the joint ETSUECMA work in the area of PTN standardisation. This ETR was produced by ECMA using the ECMA guidelines for the production of ETRs and using the ECMA stylesheet. In order to avoid undue delays in the publication of the ETR, it has been agreed that this ETR will not be converted to the E
23、TSI stylesheet. Previous page is blank 3404583 O068782 814 D Page 9 ETR 079:1993 1 Scope Private Telecommunication Networks (PTNs), as described in Technical Report ECMA TR/57, provide services to their users based on the services provided to users of public ISDNs and described in the 1.200 series o
24、f Recommendations from CCITT. Whilst basic services (bearer services and teleservices) available to users of public ISDNs are generally available in the same form to users of PTNs, the situation with supplementary services is more complicated: - - - PTNs offer some supplementary services which are n
25、ot generally available to users of public ISDNs; a few public ISDN supplementary services are not applicable to PTNs; some supplementary services available to users of public ISDNs are available in a modified form to users of PTNs. This ETR therefore contains brief descriptions of supplementary serv
26、ices typically offered by PTNs, some of which are currently undergoing standardization. Relationships with corresponding standardized services in public ISDNs are also described, where applicable. ECMA uses the term Additional Network Feature (ANF) to describe certain features which cannot correctly
27、 be described as supplementary services but, like supplementary services, enhance the control of basic services. Whilst a supplementary service is made available to individual users for the direct benefit of those users, an ANF operates autonomously within a PTN and enhances the operation of the PTN
28、 for the benefit of all users or of the PTN administration. This ETR also considers some ANFs. The list of supplementary services and ANFs covered by this ETR is not intended to be exhaustive. An attendant is classed as a special type of PTN user. This ETR also considers the special characteristics
29、of attendants and the applicability of supplementary services to attendants. The purpose of this ETR is to guide manufacturers of PTN equipment and operators of PTNs in the selection of supplementary services and ANFs to be made available. It can also act as a tool for identifying potential candidat
30、es for standardization, although the appearance of a supplementary service in this ETR does not imply that it should or will be standardized for PTNs. Where an ETS (European Telecommunications Standard) exists containing a service description for a supplementary service or ANF described in this ETR,
31、 the service description in that ETS should be regarded as correct in the event of conflict with the description in this ETR. Deviation from a description in this ETR may be found necessary during the more detailed investigations involved in the writing of a Standard. The use of Computer-Supported T
32、elecommunication Applications (CSTA) in the provision of supplementary services and ANFs is outside the scope of this ETR. 2 References ETS 300 189 (1992) ECMA-133 Addressing in Private Telecommunication Networks Reference Configurations for Calls through Exchanges of Private Telecommunication Netwo

45、 In particular, most of the supplementary services which are being specified by ETSI for public ISDNs in Europe are included. NOTE I Supplementary services which have not been standardized can still be supported in a PTN. Signalling protocols at the Q and S reference points will provide escape mecha
46、nisms for manufacturer specijc information for the support of supplementary services which are not standardized, or for the support of non- standard extensions to standardized supplementary services. For each supplementary service, a brief description is given. The anticipated impact of each supplem
47、entary service on signalling at the Q and S reference points is explored briefly. Should the service be standardized, the full impact on signalling will be revealed when the stage 2 specification is complete. Finally, the relationship of each supplementary service with the corresponding supplementar
48、y service, if any, in public ISDNs and the impact on signalling at the T reference point are discussed. Certain supplementary services of public ISDNs are used by PTNs, even though PTNs do not provide corresponding supplementary services. These are: 1. Direct Dialling In (DDI). PTNs can enter into a
49、rrangements with public ISDNs for DDI, so that incoming calls can be addressed directly to called PTN users. A DDI call from a public ISDN is progressed across the PTN and to the called PTN user as a basic call. Sub-addressing (SUB). PTNs can enter into arrangements with public ISDNs for Sub-addressing, so that incoming calls can be accompanied by a called party sub-address if supplied by the calling user. Basic call signalling protocols at the S and Q reference points will provide for the transmission of a called party sub-address to a called PTN user, and therefore there is no need
