17、 by: 1 Scope This European Telecommunication Standard (ETS) specifies the Service Specific Co-ordination Function (SSCF) for support of signalling at the User-Network Interface (UNI) for the pan-European Broadband Integrated Services Digital Network (B-ISDN) as provided by European public telecommun
18、ications operators. The SSCF at UNI is a function which is part of the Signalling ATM Adaptation Layer (SAAL) at the UNI of the B-ISDN. This function is used to map the service of the Service Specific Connection Oriented Protocol (SSCOP) of the AAL to the needs of layer 3 protocols for access signal
19、ling across the UNI. This ETS covers the aspects of the SSCF of the complete AAL structure for signalling applications at the UNI defined in ITU-T Recommendation Q.2100 8, and describes the relationship to the protocol entity for access signalling specified in ETS 300 443-1 12 and the SSCOP specifie
20、d in ETS 300 436-1 ll. This ETS is applicable to equipment to be attached at either side of the B-ISDN UNI when B-ISDN access signalling is to be supported. Page 1 , clause 2, first paragraph Replace the first paragraph of clause 2 by: This ETS incorporates by dated and undated reference, provisions
21、 from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this ETS only when incorporated in it by amendment or revi
22、sion. For undated references the latest edition of the publication referred to applies.
