ITU-T Recommendations

This Recommendation is part of a series of Recommendations that specify the CORBA interface requirements for communication between an Operations System (OS) and a Network Element (NE), between an OS and a Mediation Device (MD), between an OS and a Q Adapter (QA), and between OSs in a Telecommunication Management Network (TMN). This Recommendation provides a Stage 2 and Stage 3 Description for Alarm Surveillance to support the associated TMN management service component described in ITU-T Rec. M.3400.In this Recommendation, both fine-grained and coarse-grained (i.e. facade) interfaces are defined for the alarm management functions. The fine-grained and facade interfaces provide the same support for alarm management. Both can be used with fine-grained and coarse-grained managed objects (e.g. those defined in ITU-T Rec. M.3120).The primary purpose of this Recommendation is to provide a set of application messages and associated support objects for the support of communication across CORBA interfaces. Because of the desirability of providing common TMN solutions, these messages and support objects are expected to be applicable to other TMN or TMN-related interfaces.
