7、nections to form a reconfigurable leased service Summary This ITU-T Recommendation is one of the series of M.3100-M.3200 TMN management service Recommendations. Specifically, it provides a GDMO-based information model to support the real time management of preprovisioned leased circuit services as s

8、pecified in ITU-T Recommendation M.3208.2. The model enables service customers to request, via a service layer X interface, the interconnect of preprovisioned service link connections to form a leased circuit service. Also included in this ITU-T Recommendation are Unified Modelling Language diagrams

9、 describing selected aspects of the model and selected management functions and processes. Source ITU-T Recommendation M.3108.2 was prepared by ITU-T Study Group 4 (1997-2000) and approved under the WTSC Resolution 1 procedure on 4 February 2000.

11、lecommunications. The ITU Telecommunication 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 Tele

12、communication Standardization Conference (WTSC), 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 WTSC Resolution 1. In some

13、 areas of information technology which 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

ITU-T Recommendation M.3208.2 applies these management functions to the

27、case in which service customers manage preprovisioned resources. In this application, the service creation process from the submission of the customer request to create a service until the service is available for use only involves connecting existing, preprovisioned resources. The connection of the

28、 preprovisioned resources is normally completed within a very short time interval, i.e. nearly instantaneously. ITU-T Recommendation M.3108.1 provides a GDMO-based information model to support the management of the leased circuit service as outlined in ITU-T M.3208.1. This ITU-T Recommendation provi

29、des a GDMO-based information model that supports the services specified in ITU-T M.3208.2. The information model is for use across a service layer X interface, among service customers, service providers, and network providers for the purposes of managing the leased circuit services specified in ITU-

30、T Recommendation M.3208.2. It may optionally be used at the service layer within an administration.
