scope:
The present document addresses the requirements of network and service providers of Asynchronous Transfer Mode (ATM) cross connected networks for establishing, maintaining and releasing Virtual Path (VP) and / or Virtual Channel (VC) connections (generally denoted as 'VP/VC connections' in the present document), which span several administrative ATM domains. These requirements are satisfied by the use of a standardized interface (the "X-interface") between Operation Systems belonging to different network operators.
Readers of the present document should be made aware that the abbreviation 'PNO' is taken to mean Providing Network Operator. In the previous version of the present document (and related documents), PNO was defined as Public Network Operator. The change in definition has been provided to reflect the change in market conditions for provision of interconnected telecommunications services. However, it is considered necessary to retain the abbreviation 'PNO' because it is found in many of the managed object definitions used to specify the X-interface. It would be disadvantageous to introduce major changes in these managed object definitions, which serve purely technical purposes for management of interconnections only.
The present document contains a general overview describing the different management areas that will be covered in the different X-interface ENs - configuration, alarm and performance - as well as the relationships between them.
The present document describes the configuration management area covering the following aspects:
- a management architecture that shows how the X-interface is to be used between service or network providers;
- the management services and functions needed to manage ATM connections, which span several administrative domains. These management services and functions cover the requirements for the X- interface;
- the management information crossing the X-interface. This management information specification uses the Guidelines for the Definition of Managed Objects GDMO formalism, described in ITU-T Recommendation X.722 [4].
