5 OAM Operation and Maintenance Overview
6 ======================================
8 The O-RAN SC OAM project provides administrative and operator
9 functions for O-RAN components, such as Near-Realtime-RAN-Inelegant-Controller,
10 O-RAN Centralized Unit, O-RAN Distributed Unit and O-RAN Radio Unit.
12 The project follows the specifications for the `O1 interface <https://www.o-ran.org/specifications>`_
13 as provided by O-RAN Working Group 1 (new 10).
15 The O-RAN-SC OAM project adds features and functions to the OpenDaylight-based ONAP
16 controller 'CCSDK/SDNC'. It is built on the Common Controller Framework
17 to control and to manage O-RAN ManagedElements and O-RAN ManagedFunctions.

27 The project uses the following Linux Foundation resources:
29 * The source code is maintained in this Gerrit:
30 `<https://gerrit.o-ran-sc.org/r/admin/repos/oam>`_
32 * The build (CI) jobs are in this Jenkins:
33 `<https://jenkins.o-ran-sc.org/view/oam/>`_
35 * Issues are tracked in this Jira:
36 `<https://jira.o-ran-sc.org/projects/OAM/>`_
38 * Project information is available in this Wiki:
39 `<https://wiki.o-ran-sc.org/display/OAM/Operations+and+Maintenance>`_
45 According to the `O-RAN-OAM-Architecture document <https://www.o-ran.org/specifications>`_
46 all ManagedElements (ME) (near-real-time-RIC, O-CU-CP, O-CU-UP, O-DU and O-RU)
47 implement the O1-interface.
49 The O-RAN-OAM-interface specification defines
51 - a NetConf-Server for Configuration Management (CM) and
52 - a http-client for Fault Management (FM), Performance Management (PM) and other
53 events on each Management-Service-Provider (MnS-Provider) running on the
56 THe O-RAN-SC-OAM project provides reference implementation according to the
57 O-RAN OAM documents. In addition it provides a lightweight MnS-Consumer for
58 development and module test purposes. The assumption is that the projects
59 for the ManagedElements can concentrate on the more important user-plane.
61 Each project requires its own OAM repository to address the specific needs
62 of the ManagedFunction.
64 The following O-RAN specifications are considered during implementations:
