ATIS’ Open RAN Committee (ORC), through its Memorandum of Understanding (MoU) with the O-RAN ALLIANCE, publishes O-RAN ALLIANCE specifications as ATIS Standards. This process is known as “transposition” of the O-RAN ALLIANCE specifications.
All the documents listed in the table below have been approved as ATIS Standards. The technical content of the ATIS Standards, which has been approved by ATIS ORC, is identical to the corresponding O-RAN ALLIANCE specifications; therefore, ATIS does not independently publish the text of these standards. Users of the ATIS Standards should refer to the corresponding O-RAN ALLIANCE specifications in the table below.
These ATIS Standards are maintained by the ATIS Open RAN Committee (ORC) and will be updated as required.
