  1. Hello, can someone please update me on the status of the O-CU component? I can only find this related repository which has not been updated in 16 months - Is there a more updated code base somewhere and is there any documentation I can follow?

    Many thanks,


    1. Michael, the O-CU project was halted due to a lack of contributor resources. Today, OSC uses a binary test stub provided by Radisys for end-to-end testing.
