1、 AMERICAN NATIONAL STANDARD FOR TELECOMMUNICATIONS ATIS-1000638.1999(R2015) B-ISDN ATM Adaptation Layer Service Specific Coordination Function for Support of Signaling at the User-to-Network Interface (SSCF at the UNI) As a leading technology and solutions development organization, ATIS brings toget
2、her the top global ICT companies to advance the industrys most-pressing business priorities. Through ATIS committees and forums, nearly 200 companies address cloud services, device solutions, emergency services, M2M communications, cyber security, ehealth, network evolution, quality of service, bill
3、ing support, operations, and more. These priorities follow a fast-track development lifecycle from design and innovation through solutions that include standards, specifications, requirements, business use cases, software toolkits, and interoperability testing. ATIS is accredited by the American Nat
4、ional Standards Institute (ANSI). ATIS is the North American Organizational Partner for the 3rd Generation Partnership Project (3GPP), a founding Partner of oneM2M, a member and major U.S. contributor to the International Telecommunication Union (ITU) Radio and Telecommunications sectors, and a memb
5、er of the Inter-American Telecommunication Commission (CITEL). For more information, visit . AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards d
6、eveloper. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that a
7、ll views and objections be considered, and that a concerted effort be made towards their resolution.

17、 the UNI, which is used to mapthe service of the Service Specific Connection Oriented Protocol (SSCOP) to theneeds of the UNI layer 3 protocol (e.g., ITU-T (formerly CCITT) RecommendationQ.2931). This function is called Service Specific Coordination Function (SSCF) forsignalling at the UNI.The ATM A
18、daptation Layer (AAL) is defined to enhance the services provided by theATM layer to support the functions required by the next higher layer. Different AALssupport various protocols to suit the different needs of a range of AAL service users.One particular type of AAL service user is the signalling
19、AAL (SAAL) comprises AALfunctions necessary to support such a signalling entity. The structure of the SAAL isdefined in ITU-T Recommendation Q.2100. The SAAL is divided into two sublayers:a Common Part Convergence Sublayer (CPCS) and a Service Specific ConvergenceSublayer (SSCS). The common part pro
20、tocol is used as a basis for the service spe-cific part for signalling and is defined in ITU-T Recommendation I.363.5. The SSCS isfunctionally divided into two parts. The Service Specific Connection Oriented Proto-col (SSCOP), which provides an assured data transfer service and the Service Spe-cific
21、 Coordination Function (SSCF). The SSCOP is defined in draft ITU-TRecommendation Q.2110.The SSCF at the UNI performs a coordination function between the service requiredby the signalling layer 3 (Q.2931) user and the service provided by SSCOP. This rec-ommendation describes for the SSCF at the UNI t
22、he mapping of primitives from layer3 to signals of the SSCOP and vice versa.The current revision of this standard was made to indicate that the American NationalStandard for a B-ISDN ATM adaptation layer service specific coordination functionfor support of signaling at the UNI is the ITU-T Recommend
23、ation Q.2130, B-ISDNSignalling ATM Adaptation Layer - Service Specific Coordination Function for Sup-port of Signalling at the User-to-Network Interface (SSCF at the UNI).Suggestions for improvement of this standard are welcome.
