17、c telecommunication services for the pan-European Broadband Integrated Services Digital Network (B-ISDN) as provided at the TB reference point or coincident SB and TB reference point (as defined in ITU-T Recommendation 1.413) by means of the Digital Subscriber Signalling System No. two (DSS2) protoc

18、ol. Stage three identifies the protocol procedures and switching functions needed to support a telecommunications service (see ITU-T Recommendation I. 130 84). In addition, the present document specifies the protocol requirements at the TB reference point where the service is provided to the user vi

NOTE 1: Procedures at the TB reference point, to support the access of a private B-ISDN to the public B-ISDN, are not explicitly identified in the present document, however, some procedures are applicable only at the TB reference point. The present document also specifies the par

20、ticular features required to provide 64 kbids based circuit-mode ISDN services in B-ISDN and to support access interworking between B-ISDN and N-ISDN. A basic telecommunications service is a fundamental type of service. It forms the basis on which supplementary services may be added. NOTE 2: Specifi

21、c requirements of individual B-ISDN connection-oriented basic telecommunication services are not covered by the present document. Further parts of the present document provide the method of testing and detailed application specific requirements to determine conformance to the present document. The p

22、resent document is applicable to equipment supporting connection-oriented basic B-ISDN telecommunication services, to be attached at either side of a TB reference point or coincident SB and TB reference points when used as an access to the public B-ISDN.
