16、scriber Signalling System No. two (DSS2)protocol. Stage three identifies the protocol procedures and switching functions needed to support a telecommunicationsservice (see CCITT Recommendation I.130 1).In addition, the present document specifies the protocol requirements at the TBreference point whe
17、re the service isprovided to the user via a private B-ISDN.NOTE: Procedures at the TBreference point, to support the access of a private B-ISDN to the public B-ISDN, arenot explicitly identified in the present document, however, some procedures are applicable only at the TBreference point.A basic Te
18、lecommunications service is a service to which supplementary services may be added.Further parts of the present document provide the method of testing and detailed application specific requirements todetermine conformance to the present document.The present document is applicable to equipment suppor
