GeneralThis Recommendation has been developed in accordance with the methodology defined in RecommendationsZ.332 and Z.333.The main part of this Recommendati
5、on deals with the model of the subscriber Administration. A glossary of theterms used is also included. The list of functions to be controlled by means of MML is contained in Annex A. For eachof these functions one or more MML functions can be derived and each of them can be described using themetal
6、anguage defined in Recommendation Z.333 in order to detail the relevant information structure.Annex B contains a list of MML functions and the information structure diagrams associated to each of them tobe used as guidelines.2 IntroductionThe scope of this Recommendation is the operational aspect of
7、 the functional area of subscriber administration.It has been recognized that subscriber Administration is related to various administrative procedures, belongingto other functional areas, which have to be carried out prior to or in functional relationship to the jobs to be controlledby MML.Such adm
8、inistrative procedures are Administration dependent with different degrees of data processing support.They can be considered as the administrative environment.3 Subscriber administration model3.1 IntroductionThe model is applicable to subscribers to whom normal telephone services (POTS: Plan of Tele
9、phone Services)are offered.For the representation of the model the metalanguage defined in Recommendation Z.333 has been used.For the purposes of this Recommendation subscribers have been divided into the following two classes (seeFigures B-1/Z.334, B-2/Z.334 and B-3/Z.334: single-line subscribers,
10、comprising single-party and multi-party lines; multi-line subscribers, comprising PBX (without direct inward dialling), PABX (with direct inwarddialling) and subscriber line groups.Both single-line and multi-line subscribers are embedded in an administrative environment. This environmentmay comprise
11、 all data relevant for administering the various types of subscribers. Examples for such data are addressesof subscribers and subscribers features. The administrative environment aspects are not considered in detail in thismodel.3.2 Description of model3.2.1 GeneralSubscribers are distinguished by t
12、he data describing the way in which they are connected to and managed bythe public exchange, including data related to the associated hardware equipment in the exchange. Examples are twoparty lines, ordinary subscriber lines, PABXs multi-party lines.From the Administration view every subscriber fall
13、s into one of the two main types identified in the model,single- or multi-line subscribers. Due to the different association of information entities needed for the representationof these two main types, two different sets of MML functions are felt to be appropriate. The relevant informationentities
14、defined in the model are described in the following sections.3.2.2 Line characteristicsLine characteristics are described by their attributes which may include information about class of line, kind of2 Fascicle X.7 - Rec. Z.334signalling, attenuation equalization, traffic directions, etc.3.2.3 Line
15、group characteristicsLine group characteristics are described by their attributes which may include information about kind ofsignalling, class of line, traffic directions etc., associated to all lines forming the group.3.2.4 Facility characteristicsFacility characteristics are described by their att
16、ributes. They include all information about supplementaryservices which can be assigned to a given subscriber. Examples are abbreviated dialling, do not disturb service, wake-up service, charging information like normal charging or free of charge.There are attributes which can only be controlled by
17、the Administration while others are primarily controlled bythe subscribers themselves. However, it has been recognized that in the latter case these attributes can also becontrolled by the Administration.3.2.5 Restriction characteristicsRestriction characteristics include information which indicate
18、the limitations on the regular operational mode,e.g., traffic restrictions for originating calls.3.2.6 Monitoring characteristicsMonitoring characteristics are related to particular monitoring actions, which are carried out by the system. Themonitoring actions are mainly of a temporary nature and co
19、mprise subscriber Administration functions carried out toobtain data related to calls. Examples are malicious call tracing and charging observation. Monitoring actions areactivated on subscribers or Administrations request and are described by their attributes, e.g. duration of monitoring,starting t
20、ime.3.2.7 Single-line subscriber identitySingle-line subscriber identity allows the unambiguous identification of a single-line subscriber, normally by itsdirectory number.3.2.8 Multi-line subscriber identityMulti-line subscriber identity allows the unambiguous identification of a multi-line subscri
21、ber, normally by itsdirectory numbers.3.2.9 Equipment identityEquipment identity allows the unambiguous identification of the device to which a subscriber line is connected.3.2.10 Line numberA line number allows the unambiguous identification of a line within a line group.3.2.11 Associated directory
22、 numberAn associated directory number may be entered for lines that are members of a multi-line subscriber and thatneed to have associated with them a directory number other than the multi-line subscriber identity. Examples includethe night service number for a member of a PBX or the directory numbe
23、r of a directly dialable member of a multi-linehunt group.3.2.12 StateThe state of a subscriber line identifies the current operational mode in an unique way. It may be possible tointerrogate the state of a subscriber line.4 Glossary of termssingle-line subscriber lineA line between a public exchang
