7、RMATION VIEWPOINT FOR PRE-PROVISIONED LINK CONNECTION MANAGEMENT Summary The pre-provisioned link connection management community is used to assign transport entities (link connections or connection termination points) to a caller and to control and update the available capacity of the linking entit
8、y (link or link end) that contains the transport entities. The available capacity of the linking entity contains all the unassigned transport entities. This community should be used in the case where transport entities have already been provisioned inside the linking entity using the pre-provisioned
9、 adaptation management service (G.85. 8 series of Recommendations). The capability of having pre-provisioned transport entities is available in technologies such as SDH or WDM. Source ITU-T Recommendation G.853.1 O was prepared by ITU-T Study Group 4 (1 997-2000) and was approved under the WTSC Reso
10、lution No. 1 procedure on the 26th of March 1999. Recommendation G.853.10 (03/99) 1 STD*ITU-T RECMN G*853*I,O-ENGL 1779 4Bb2591 0bb2097 197 FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Stan
11、dardization Sector (ITU-T) is a permanent organ of the ITU. The 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 Conference
12、 (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas o
13、f information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation the term recognized operating agency (ROA) includes any individual, company, corporation or governmental organization that operates a
14、 public correspondence service. The terms Administration, ROA and public correspondence are defined in the Constitution of the ITU (Geneva, 199.2). INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use o
15、f a claimed Intellectual Property Right. The 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 of approval of this Recommendatio
16、n, the ITU had not received notice of intellectual propery, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. O ITU
