A table which contains the status of latest RTP
operation.
Each conceptual row corresponds to a RTP operation
defined in rttMonCtrlAdminTable and has same index as
rttMonCtrlAdminTable.
An entry in this table is created only if the
rttMonCtrlAdminRttType is 'rtp', the rttMonEchoAdminProtocol
is 'rtpAppl' and the rttMonEchoAdminTargetAddress is
appropriately configured. The entry will start to collect
data when the rttMonCtrlAdminStatus is moved into 'active'
state. The entry will be removed when the corresponding
rttMonCtrlAdminStatus is in 'destroy' state.
