Represents the state of the association between the MG and the MGC. The possible values are: 'mgcUnassociated' : MG and MGC are not associated. For example, in the case where MGCP is the coordination protocol, it means no subscription to autonomous messages such as RSIP but control requests would be answered. 'mgcAssociated' : MG and MGC are associated. E.g. in the case where MGC is the coordination protocol, it means MGC is subscribed to autonomous messages such as RSIP. 'mgcAssociatedCommLoss' : Associated but MGC unreachable. This object is being moved to the mgcRedundancyGrpParamTable. This object is deprecated because the association state is defined per MGC redundancy group, rather than per MGC.
