Source Corrigendum 1 to ITU-T Recommendation G.8080/Y.1304 (2006) was approved o
8、n 6 September 2007 by ITU-T Study Group 15 (2005-2008) under the ITU-T Recommendation A.8 procedure. ii ITU-T Rec. G.8080/Y.1304 (2006)/Cor.1 (09/2007) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Teleco
9、mmunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization As
10、sembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology w
11、hich fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with
12、 this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory lan
13、guage such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this
14、 Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date
15、of approval of this Recommendation, ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the T

21、 reference points, where the call parameters need to be examined, e.g., different administrations, different recovery domains, etc.). 2 ITU-T Rec. G.8080/Y.1304 (2006)/Cor.1 (09/2007) 7.3.8 Link discovery process In order to assign an SNP-SNP link connection to an SNPP link, it is only necessary for
22、 the transport name for the link connection to exist. Thus it is possible to assign link connections to the control plane without the link connection being physically connected. This assignment procedure may be verified by the LRMs exchanging the Transport link connection name (i.e., CP-CP name or T
23、CP-TCP name) that corresponds to the SNP. Note that the fully qualified SNPP link name is a control plane name reflecting the structure of transport plane resources. 7.4 Protocol controller (PC) components ITU-T Y-SERIES RECOMMENDATIONS GLOBAL INFORMATION INFRASTRUCTURE, INTERNET PROTOCOL ASPECTS AN
