3、s Network(PISN) -Specification, Functional Model andInformation Flows -Do Not Disturb and Do Not DisturbOverride Supplementary Services(DND(O)SD).Brief HistoryThis Standard is one of a series of ECMA Standards defining services and signalling protocols applicable to Private IntegratedServices Networ

4、ks (PISNs). The series uses ISDN concepts as developed by ITU-T and conforms to the framework ofInternational Standards for Open Systems Interconnection as defined by ISO/IEC. It has been produced under ITSTC workitem M-IT-05 2.2 and under ETSI work item DE/ECMA-00013.This particular Standard specif

5、ies the Do Not Disturb (DND) and Do Not Disturb Override (DNDO) supplementary services.This Standard is based upon the practical experience of ECMA member companies and the results of their active andcontinuous participation in the work of ISO/IEC JTC1, ITU-T, ETSI and other international and nation

6、al standardizationbodies. It represents a pragmatic and widely based consensus.There are currently no equivalent services specified by ITU-T or ETSI for public ISDNs.Compared to the 1st Edition of Standard ECMA-193 (published by ECMA in June 1993), this 2nd Edition incorporateschanges in order to ac

23、c services are specified in ECMA-142.SS-DND is a supplementary service which enables a served user to cause the PISN to reject any calls, or just thoseassociated with a specified basic service, addressed to the served users PISN number. The calling user is given anappropriate indication. Incoming ca

24、lls are rejected as long as the service is active. The served users outgoing service isunaffected.SS-DNDO is a supplementary service which enables a served user to override SS-DND at a called user; that is, toallow the call to proceed as if the called user had not activated SS-DND.SS-DND and SS-DNDO

25、 are described separately because SS-DND is a service used by a called user, and SS-DNDO isa service used by a calling user. This leads to describing two very related state machines.NOTE 1It is possible to implement SS-DND without implementing SS-DNDO.Supplementary service specifications are produce

26、d in three stages, according to the method described in ETS 300 387.This Standard contains the stage 1 and stage 2 specifications of SS-DND and SS-DNDO. The stage 1 specifications(clauses 6 and 7) specify the supplementary service as seen by users of PISNs. The stage 2 specification (clauses 8 and9)

27、 identify the functional entities involved in the supplementary service and the information flows between them.2 ConformanceIn order to conform to this Standard, a stage 3 standard shall specify signalling protocols and equipment behaviour thatare capable of being used in a PISN which supports the s

28、upplementary service specified in this Standard. This meansthat, to claim conformance, a stage 3 standard is required to be adequate for the support of those aspects of clauses 6 to9 which are relevant to the interface or equipment to which the stage 3 standard applies.The stage 1 and stage 2 clause

29、s which a stage 3 standard for the Do Not Disturb supplementary service is required tosupport are clauses 6 and 8.The stage 1 and stage 2 clauses which a stage 3 standard for the Do Not Disturb Override supplementary service isrequired to support are clauses 7 and 9.3 References (normative)The follo

30、wing standards contain provisions which, through reference in this text, constitute provisions of this Standard.All standards are subject to revision, and parties to agreements based on this Standard are encouraged to investigate thepossibility of applying the most recent editions of the standards i
