The stage one aspects are detailed in ETS 300 199 (1994) [14],ETS 300 200 (1994) [15], ETS 300 201 (1994) [16], ETS 300 202 (1994) [17] and EN 301 133 [18]. The stage twoaspects are detailed in ETS 300 203 (1994), ETS 300 204 (1994), ETS 300 205 (1994) and ETS 300 206 (1994).Changes from the previous version of the present document are shown in annex B.SIST EN 300 207-1 V1.2.5:2003

ETSIEN 300 207-1 V1.2.5 (1998-10)71ScopeThis first part of EN 300 207 specifies the stage three of the diversion supplementary services for the pan-EuropeanIntegrated Services Digital Network (ISDN) as provided by European public telecommunications operators at theT reference point or coincident S and T reference point (as defined in ITU-T Recommendation I.411 [6]) by means of theDigital Subscriber Signalling System No. one (DSS1). Stage three identifies the protocol procedures and switchingfunctions needed to support a telecommunication service (see CCITT Recommendation I.130 [3]).In addition, the present document specifies the protocol requirements at the T reference point where the service isprovided to the user via an intermediate private ISDN.The present document does not specify the additional protocol requirements where the service is provided to the user viaa telecommunications network that is not an ISDN.The diversion supplementary services comprise the following services:-Call Forwarding Unconditional (CFU) supplementary service;-Call Forwarding Busy (CFB) supplementary service;-Call Forwarding No Reply (CFNR) supplementary service;-Selective Call Forwarding Unconditional (SCFU) supplementary service-Selective Call Forwarding Busy (SCFB) supplementary service;-Selective Call Forwarding No Reply (SCFNR) supplementary service;-Call Deflection (CD) supplementary service.The CFU supplementary service enables a served user to have the network redirect to another user calls which areaddressed to the served user's ISDN number. The CFU supplementary service may operate on all calls, or just thoseassociated with specified basic services. The served user's ability to originate calls is unaffected by the CFUsupplementary service. After the CFU supplementary service has been activated, calls are forwarded independent of thestatus of the served user.The CFB supplementary service enables a served user to have the network redirect to another user calls which areaddressed to the served user's ISDN number and meet busy. The CFB supplementary service may operate on all calls, orjust those associated with specified basic services. The served user's ability to originate calls is unaffected by the CFBsupplementary service.The CFNR supplementary service enables a served user to have the network redirect to another user calls which areaddressed to the served user's ISDN number, and for which the connection is not established within a defined period oftime. The CFNR supplementary service may operate on all calls, or just those associated with specified basic services.The served user's ability to originate calls is unaffected by the CFNR supplementary service.The SCF supplementary service enables a served user to specify the forwarding of their incoming calls to a selecteddestination subject to certain conditions or circumstances e.g. the calling line identity of the calling user. The user is alsoallowed to interrogate the screening list.The CD supplementary service enables the served user to respond to an incoming call by requesting redirection of thatcall to another user. The CD supplementary service can only be invoked before the connection is established by theserved user, i.e. in response to the offered call, or during the period that the served user is being informed of the call. Theserved user's ability to originate calls is unaffected by the CD supplementary service.The diversion supplementary services are applicable to all circuit-switched telecommunication services.Further parts of EN 300 207 specify the method of testing required to identify conformance to the present document.The present document is applicable to equipment supporting at least one of the diversion supplementary services, to beattached at either side of a T reference point or coincident S and T reference point when used as an access to the publicISDN.SIST EN 300 207-1 V1.2.5:2003
