=== A1 Heartbeat ==

RNote over A1TERM, xAPP 
  Near-RT-RIC A1 Mediator Health is addressed by RIC Self-Check Flows
End Note
RNote over NONRTRIC, SMO_A1 
  NONRTRIC Health is addressed by NONRTRIC's internal Self-Check Flows
End Note


=== A1 Policy Management Service Operation ==

RNote over NONRTRIC, SMO_A1  #lightsalmon
  Non-RT-RIC Policy Management Service provides mediation for all A1 messages. 
  For optional consistency function tests OTF may directly perform operations to SDNC A1 Adapter or to near-RT-RIC A1 mediator. 
  Such direct connections would have unpredicatable or undesired effects in a non-test scenario.
