Martin Skorupski, can you spend sometime talking about your proposal for API modification process after M3 and the changes you are recommending. Want to make sure that impacted parties have a chance to answer any questions they might have before implementation.

5 min	Agenda bashing	Mahesh Jethanandani
10 min	JIRA ODUHIGH_322
10 min	O1/VES support from O-RU, O-DU, O-CU and Near RT-RIC	All

Martin Skorupski clarified the changes agreed to as part of JIRA ODUHIGH_322, the cell-state is supposed to reflect the state of the link between O-DU Low and O-RU, and not the state of the cell. Vidhu Shekhar Pandey and HariomGupta(HCL) confirmed that that is what they are implementing as part of O-DU. Note, there is a separate leaf called status, which was reflecting the status of the link between O-DU Low and O-RU, but that was used by the RPC, and should not be used for reflecting the state of the link.
On the question of support for O1/VES interface from different network elements, here is where we stand:
- O-RU will be sending a NETCONF notification towards the SMO, which the SMO will translate into a O1/VES event and send to the O1/VES collector.
- O-DU sends its PNF Registration as O1/VES event to the SMO before SMO can administratively bring up the link between O-DU and O-RU.
- In the TOC meeting there was discussion of what O-CU will or will not support from an O1/VES perspective. See action item below.
- The same is true for Near RT-RIC. Note that Thoralf Czichy had provided this link before as far as support for Alarms are concerned.

user-165cf or user-30c9d to confirm what support O-CU will provide as part of supporting the O1/VES interface.
Thoralf Czichy to confirm what support the Near RT-RIC will provide as part of supporting the O1/VES interface.
