All implementation details are explained here: https://wiki.onap.org/display/DW/A1+Adapter+in+ONAP + +How to Use +~~~~~~~~~~ + +Following steps describe a general procedure about how to use A1 adaptor. + +1.

Detailed information can be found at its repo: https://gerrit.o-ran-sc.org/r/gitweb?p=ric-plt%2Fric-dep.git;a=shortlog;h=refs%2Fheads%2Fmaster. + +Test Status and Plans +~~~~~~~~~~~~~~~~~~~~~ + +For ONAP Frankfurt, A1 adaptor has not been involved in a full closed loop use case. A1 adaptor has gone through a unit test with A1 mediator in OSC as a underlying device. It has been tested for receiving A1 policy via DMaaP and publishing a response back to DMaaP as well as notification.
