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 developer. Consensus is established when, in the judgment of t
6、he 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 all views and objections be considered, and that a concerted e
7、ffort be made towards their resolution.

17、Layer (AAL). This protocol, called the Service SpecificConnection Oriented Protocol (SSCOP), provides assured data delivery betweenAAL connection endpoints.The ATM Adaptation Layer (AAL) is defined as enhancing the services provided bythe ATM layer to support the functions required by the next highe
18、r layer. DifferentAALs support various protocols to suit the different needs of a range of AAL serviceusers. One particular type of AAL service user is the signaling entity wishing to com-municate with a peer entity. The signaling AAL (SAAL) comprises AAL functions nec-essary to support such a signa
19、ling entity. The structure of the SAAL is defined inT1.636-1999. The SSCOP has been defined to provide functions required in theSAAL.The SAAL is a combination of two sublayers: a common part and a service specificpart. The common part protocol is defined in ITU-T Recommendation I.363.5. Theservice s
20、pecific part is also known as the Service Specific Convergence Sublayer(SSCS). In the SAAL, the SSCS itself is functionally divided into the SSCOP and aService Specific Coordination Function (SSCF), which maps the services provided bythe SSCOP to the needs of the user of the SAAL. This structure all
21、ows a commonconnection oriented protocol with error recovery (the SSCOP) to provide a genericreliable data transfer service for different AAL interfaces defined by the SSCF. Twosuch SSCFs, one for signaling at the User Network Interface (UNI) and one for sig-naling at the Network to Network Interfac
22、e (NNI), have been defined in ITU-T Recom-mendations Q.2130 and Q.2140, respectively. It is also possible to define additionalSSCFs over the common SSCOP to provide different AAL services.The SSCOP is a peer-to-peer protocol that provides the following functions:- transfer of user data with sequence
23、 integrity,- error correction by selective retransmission,- flow control,- connection control,- error reporting to layer management,- connection maintenance in the prolonged absence of data transfer,- local data retrieval by the user,- error detection of protocol control information, and- status rep
24、orting.This standard describes for SSCOP the necessary elements for layer-to-layer com-munication, the elements for peer-to-peer communication, a detailed protocol specifi-cation, and examples of SSCOP operation. The current revision of this standard was made to indicate that the American NationalSt
25、andard for a B-ISDN ATM adaptation layer service specific connection orientedprotocol is the ITU-T Recommendation Q.2110, B-ISDN ATM Adaptation Layer - Ser-vice Specific Connection Oriented Protocol (SSCOP).Suggestions for improvement of this standard are welcome. They should be sent tothe Alliance
