NSP supports a variety of Nokia and multi-vendor devices via pluggable adaptor artifacts, sometimes called "MDM adaptors". In service management, the application functions that are available for model-driven NEs can vary based on the installed adaptor artifacts. To verify the adaptor artifacts you have installed, check the Managed Network Elements list in the NSP Device Management views. The Applicable Adaptors view for the NE provides the list of adaptor artifacts that are installed for each application.
