Architecture
In the normal E2E Network Slice architecture which is supported in the ONAP, RAN NSSMF is responsible for the creation of Transport Front Haul and Back Haul slice subnet instances as defined in the architecture below.
In this scenario 2, NSMF itself will be taking care of the TN front haul and back haul slice subnet creation as mentioned in the architecture below.

Manual Configuration for 5G Network Slicing#A&AIConfiguration
In the manual configuration sections, for creating the optimization policies, the following set of policies needs to be used instead of the one mentioned in the page
Running the simulators
Instructions to setup CN NSSMF simulators can be found here: External Core NSSMF Simulator Use Guide
UUI operations (Creating communication service, Activation)
There are no changes in the UI for the NSMF based TN slices. It is same as the usual operations. The UUI operation details can be found here.
