8、ion Standard (ETS) has been produced by the Network Aspects (NA) Technical Committee of the European Telecommunications Standards Institute (ETSI). In accordance with CCITT Recommendation 1.130 3, the following three level structure is used to describe supplementary telecommunications services for t

9、he Integrated Services Digital Network (ISDN): - Stage 1: is an overall service description, from the users standpoint; - Stage 2: identifies the functional capabilities and information flows needed to support the service described in stage 1 ; and - Stage 3: defines the signalling system protocols

10、and switching functions needed to implement the service described in stage 1. The principle of this three level structure has been used to develop the service description for the Calling Line Identification Presentation (CLIP) supplementary service as provided by European public telecommunication op

11、erators for the Public Switched Telephone Network (PSTN). This ETS details the stage 1 aspects (overall service description) for the CLIP supplementary service for the PSTN. ETS 300 659-1 5 specifies the subscriber line protocol for various PSTN display services at terminal equipment in the “on-hook

12、 state and this includes the protocol for the CLIP supplementary service. Date of adoption Date of latest announcement of this ETS (doa): 21 February 1997 30 June 1997 Date of latest publication of new National Standard or endorsement of this ETS (dop/e): 31 December 1997 Date of withdrawal of any c

14、ge one of the Calling Line Identification Presentation (CLIP) supplementary service for the Public Switched Telephone Network (PSTN) as provided by European public network operators. Stage one is an overall service description from the users point of view (see CCITT Recommendation 1.130 3), but does

15、 not deal with the details of the human interface itself. This ETS defines the interworking requirements between PSTNs and private networks, PSTNs and Integrated Services Digital Networks (ISDNs), and Public Land Mobile Networks (PLMNs). Interactions with supplementary services not listed in clause

16、8 are outside the scope of this ETS. Charging principles are outside the scope of this ETS. The CLIP supplementary service provides the called party with the possibility of receiving identification of the calling party. This ETS is applicable to the ETS containing the subscriber line protocol to sup

17、port the CLIP supplementary service. Where the text indicates the status of a requirement (i.e. as strict command or prohibition, as authorization leaving freedom, or as a capability or possibility), this shall be reflected in the text of that standard. Furthermore, conformance to this ETS is met by

18、 conforming to the standards containing the subscriber line protocol to support the CLIP supplementary service with the field of application appropriate to the equipment being implemented. Therefore no method of testing is provided for this ETC. 2 Normative references This ETS incorporates by dated

19、or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to, or revisions of any of these publications apply to this ETC only when incorp

20、orated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.

24、 the CLIP supplementary service is provided. It is the called user who receives the Calling Line Identity of the calling party. analogue access: An ordinary subscriber line access or a Private Branch Exchange (PBX) analogue line access. 4 Abbreviations For the purposes of this ETS, the following abb

25、reviations apply: CLIP CLIR ISDN PBX PLMN PSTN Calling Line Identification Presentation Calling Line Identification Restriction Integrated Services Digital Network Private Branch Exchange Public Land Mobile Network Public Switched Telephone Network 5 Description The CLIP supplementary service shall

26、apply to an analogue access. NOTE: Some networks may provide the CLIP supplementary service only for analogue accesses that are connected to digital exchanges. The CLIP supplementary service provides the served user with the possibility of receiving calling line identification of the calling party.

27、The network shall deliver the calling line identity to the served user during call establishment, according to the following service provider options: a) prior to ringing; or b) during the ringing phase (e.g. during the first long silent interval). As a service provider option, additional informatio

28、n can be provided to the served user. The content and use of this additional information is outside the scope of this ETS. 6 Procedures 6.1 Provision and withdrawal The CLIP supplementary service shall either be provided after prior arrangement with the service provider or be generally available. Th

29、e CLIP supplementary service shall be withdrawn by the service provider upon the request of the subscriber, or for service provider reasons. 6.2 Normal procedures 6.2.1 Registration and erasure Not applicable. Page 9 ETS 300 648: March 1997 STD-ETSI ETS 300 bLi8-ENGL 1777 3Li00855 OLbBb23 LibA 6.2.2

30、 Activation and deactivation lhe CUP Supplementary service shall be activated by the service provider at provision. The CLIP supplementary service shall be deactivated by the service provider at withdrawal. As a service provider option the served user can deactivate and activate the CLIP supplementa

31、ry service by using a deactivation or activation procedure from the line on which the CLIP supplementary service applies. 6.2.3 Invocation and operation The network shall automatically invoke the CLIP supplementary service during call establishment. The network shall provide the served user with the

32、 calling line identity. 6.2.4 Interrogation As a service provider option, in the case where control of activation/deactivation is provided to the served user, the served user can interrogate the status (activated or deactivated) of the CLIP supplementary service. 6.3 Exceptional procedures 6.3.1 Reg

33、istration and erasure Not applicable. 6.3.2 Activation and deactivation If the network supports the activation/deactivation procedure but cannot accept the activatioddeactivation request the served user shall be informed (e.g. option not subscribed to). 6.3.3 Invocation and operation If the presenta

34、tion of calling line identity is restricted due to the Calling Line Identification Restriction (CLIR) supplementary service (see ETS 300 49 4) then the served user shall receive an indication that the calling line identity is not available because of restriction. In some interworking situations in w

35、hich the connection is not completely supported by cuff icient signalling capability, the served user shall receive an indication that the calling line identity is not available. In the case of an originating network that does not provide the calling line identity, the served user shall receive an i

36、ndication that the calling line identity is not available. Information transfer should be stopped if the call is answered during the transmission phase of the CLIP supplementary service procedure at the served users interface. 6.3.4 Interrogation Not applicable. 7 Intercommunication considerations 7

37、.1 Interworking with public ISDNs If the calling patty is connected to an ISDN, the CLIP supplementary service shall apply. However, if the CLIR supplementary service (ETC 300 O90 2) applies to the ISDN calling user, the served user shall receive an indication that the calling line identity is not a

38、vailable because of restriction. As a service provider option, the calling line identity delivered to the served user can be composed of both the network provided number and the user provided not screened number. - STD-ETSI ETS 300 b48-ENGL 1777 W 3400855 ULb8b24 3T4 Page 10 ETS 300 648: March 1997

39、7.2 Interworking with private networks Provision of the CLIP supplementary service in the case where the called user is connected to a private network using direct dialling in capability is outside the scope of this ETS. 7.3 Interworking with PLMNs When the identity of a user in a PLMN is transferre

40、d to the PSTN, this identity can be used for the CLIP supplementary service to the served user. 8 Interactions with other supplementary services 8.1 Calling line identif ication presentation Not applicable. 8.2 Calling line identification restriction The CLIR supplementary service shall override the

41、 CLIP supplementary service unless the called user has an override category (see note). NOTE: The CLIP supplementary service can override the CLIR supplementary service when the called user has an override category. This is a national matter, the operation of which is outside the scope of this ETS. - Page 11 ETS 300 648: March 1997 STD*ETSI ETS 300 bLiB-ENGL 1777 3Li00855 O1bAb25 230 February 1996 December 1996 March 1997 History Public Enquiry PE 101: 1996-02-05 to 1996-05-31 Vote V 117: 1996-1 2-23 to 1997-02-1 4 First Edition Document history ISBN 2-7437-1 302-X Dpt lgal : Mars 1997
