Defines the relationship between a PVC and the connection-oriented AISwitch TDM backplane. The three types represented are defined as follows: Active: initiates connections across the backplane at an interval defined by the timer. Passive: waits to respond to a connection attempt across the backplane. Uses timer to wait for reset confirm from network. Accepts backplane connection if it receives reset confirmation in time. Connect on Activity: initiates connection across backplane upon the receipt of data from the network. Forwards received data once connection is established. Disconnects backplane connection if a timer interval passes with no data activity in either direction. This object will return the value none(1) if the value of aix1CircuitConType for this VC is not pvc(11). This object reflects the current operational value of this parameter. Note that unlike most operational objects, it is writable. If the value of this object is changed, it modifies the current behavior of the board, but is not saved in nonvolatile memory.
