2、 Amendments proposed by Project Team Service Descriptions for the ISDN (SDI) Text of the Recommendation adopted by Commercial Action Committee (CAC) CONTENTS 1. General Items Concerning Descriptions of Supplementary Services 2. Operational Requirements for Supplementary Services INTRODUCTION This Re
3、commendation contains the description of the supplementary services from a users point of view. The descriptions are not intended for the users, but for use within the network operators. The European Conference of Post and Telecommunications Administrations considers 1. that there is a need for a de
4、scription of the users requirements as to the elaboration of the supplementary services, 2. that the present solutions do not always meet the optimum requirements. recommends 1. that the operational requirements of the supplementary services with service prose definition and description should be ma
5、de available, 2. that the description method described in Annex O should be used in the description of operational requirements, 3. that the descriptions in this Recommendation should be used by the network operators, 4. that according to national selection, supplementary services are provided in ac
6、cordance with the descriptions in this Recommendation, 5. that national user manuals should be worked out on the basis of the text in this Recommendation, 6. that supplementary services which due to the absence of technical possibilities cannot meet all the user requirements immediately should, by w
7、ay of introduction, be provided in a reduced version, but should be improved as soon as possible to meet all the user requirements.

Annex 0.2 USER OPERATION OF SUPPLEMENTARY SERVICES INTRODUCTION This annex describes how the users are enabled to operate the supplementary services when these services h
34、ave been provided by the network operator. The provision of a supplementary service is carried out by the network operator and may be: 1. General: The service is made available to all customers without prior arrangements being made with the network operator. 2. Pre-arranged: The service is made avai
35、lable to an individual subscriber only after the necessary arrangements have been made with the network operator. The description is based on the stable states the supplementary services may reach after they have been provided by the network operator. STABLE STATES After the provision of a supplemen
36、tary service it may assume three different stable states depending on the service type: 1. Provided 2. Registered 3. Active Provided Provided is the first stable state occurring when the network operator has provided a supplementary service. The provided state is terminated through the withdrawal of
37、 the supplementary service by the network operator. At withdrawal the Supplementary service shall be deactivated automatically and registered data shall be erased.

38、PLEMENTARY SERVICES CEPT Telecom 2.2. Registered Upon provision, the first event changing a service state is the registration of the service. Registration is programming of the network for execution of the supplementary service in accordance.with the requirements of the current user. This means that
39、 user specific data for the individual supplementary service is registered in the network. Registration is the first possible user operation. Registration may be omitted if the supplementary service type does not imply the use of user specific data. ) The users possibility of registering a supplemen
40、tary service may also be omitted if the user specific data are entered permanently by the network operator at the time of provision. A few supplementary services feature automatic registration on activation of the supplementary service. This registration is then carried out on the basis of the curre
41、nt state at the users network termination. 2, The registered data is deleted through erasure. Erasure of the Supplementary service shall result in automatic deactivation. 2.3. Active In the active state where supplementary service shall be invoked automatically: 1. on the occurrence of a defined sta
42、te and/or event determined by the supplementary service type and/or through the registration, or 2. at the time determined at the registration of the supplementary service. The service may be user activated. Separate activation may be omitted if the service type implies automatic activation at the t
43、ime of provision and/or registration. Activation may also be omitted if the supplementary service in question does not imply automatic invocation. ) Depending on the supplementary service type, activation may take place either from the provided or the registered state. Termination of the active stat
44、e takes place through deactivation. ) *) 3, Call Waiting (CW) is a supplementary service which does nor imply registration. Completion of Calls to Busy Suhscriber (CCBS) is a supplementary service where registration takes place automatically. Abbreviated Dialling is a Supplementary sewice which does
45、 not imply automatic invocation. O Edition of November 20, 1992 CEPT T/CAC*S*L0-7 E 92 m 232b414 001L839 071 m CEPT Telecom TICAC S 10.7 E Annex 0.2.

46、n of supplementary services may be divided into three groups: 1. Preparation of supplementary services, 2. Manual invocation of supplementary services, and 3. Interrogation of supplementary services. Preparation of Supplementary Services Preparation of a supplementary service means that the service
47、is brought into a required stable state. The above section already indicates a need for the first four user procedures in the following description. Add to this the possibility of overwriting an earlier registration without prior erasu re. Registration Data programming makes a specific supplementary
48、 service function in accordance with the requirements of the current user. rasure The deleting of data stored against a particular user termination and supplementary service. Activation An action taken to enable a process to run as and when required by the supplementary service concerned. Deactivati
49、on An action taken to terminate the active state of the supplementary service. Overwriting Attempts to register an already registered and possibly active supplementary service shall result in automatic erasure, a new registration, and possibly activation in accordance with the data entered by the user. Before the overwring is finally approved, the user shall be warned of the erasure of the old registration through an appropriate indication. The overwriting is not effective until after approval by the user. Overwriiing will not be treated separately because apart
