View of proposed generic requirements for operations interfaces used to manage Asynchronous Transfer Mode (ATM) subnetworks. Details a set of information modeling objects needed to support the exchange of ATM subnetwork management information over a generic operations interface. Information model object set detailed here is applicable to operations interfaces that expose an ASTM Network View for subnetwork management within an administration, inclusive of interfaces between a Network Management System and the Element Management Systems managing ATM subnetworks. Issue 3 is inclusive of updates that support VP level protection (1+1) inclusion of SBV access interface support in the Network View description of ATM Network View applications for Customer Network Management (CNM) and Intercarrier Management.
