The telemanagement community has adopted CORBA as the preferred distribution technology with

which to integrate the various components of an OSS. The Multi Technology Network Management

Working Group of the TMF has been working to create a specification for an NML-EML interface.

CTM GateWay/CORBA is based on the following TMF standards:

•

The TMF.608 document is a protocol-independent information model for the network resources being

managed. The TMF.814 document is the CORBA Interface Data Language (IDL) component of the

specification; it consists of a set of definitions for specific objects and methods that are available for use

at the NML-EML interface for passing information or accomplishing specific actions. However,

TMF.814 is a specific interface implementation based on a TMF high-level business agreement

described by the TMF.513 document. To complete the document set, TMF.814A recognizes that different

parties may provide varying degrees of compliance in their implementations. The TMF.814A document

is called the Implementation Agreement, and is simply a form to be filled out by those parties

implementing TMF.814 to further describe their specific implementations to those who might use them.
