Dependency/Blockers:

• O1 configuration for day-1 shall need to be completed to start with CLA. However basic configuration e.g. cell state/operational state/admin state shall be supported initially. Use admin state as unlocked to validate the RU link failure.
• Server(VM) configuration (H/W and S/W) to mount Radisys CU as a test fixture. 
• Unable to use valgrind with Intel libraries. Debugging must be carried out with Alternate methods.
• SIB1 PDSCH reached L1 but cannot be observed in logs. Awaiting response from Intel.
• Viavi to confirm successful decoding of SSB at UE sim (TM500).
