This is the standard SNMP RowStatus column controlling creation, activation, and deletion of a channel's row in the channel table, and its allowed value is constrained by channelAdminStatus (notInService when locked, active or notReady when unlocked). An admin provisioning a new broadcast channel must walk this column through notReady/notInService to active in step with channelAdminStatus, so a stuck notReady value here signals an incomplete channel provisioning, such as vpi/vci not yet set. After creating a new channel row with vpi=0 and vci=200 but before setting channelAdminStatus to unlocked, this row would read notReady(3) until provisioning completes.
