Description: This attribute indicates the state of the trace call to the receiver. The dataTransfer value is the normal state for the call. The initializing, creatingVc, calling and enteringDataTransfer values are all normal transient states used to establish a call to the trace receiver on receipt of a Start command. These states occur during the callingReceiver state of the sessionState attribute. In the initializing state, receiver provisioning data, used to setup the call the the receiver, is being retrieved. In the creatingVc state, the local VC is being created. In the calling state, the direct call to the receiver is being connected. In the enteringDataTransfer state, the call to the receiver has been accepted and the data path is being established. The clearing, terminatingVc and terminated values are all normal transient states used to disconnect a call with the trace receiver on receipt of a Stop command. These states occur during the clearingCallToReceiver state of the sessionState attribute. In the clearing state, the call to the receiver is being cleared. In the terminatingVc state, the local VC is being destroyed. In the terminated state, the call is down and all cleanup is complete. A value of reseting indicates a data sequencing problem has occured on the call. This value is applicable for sessions to X.25 trace receivers only and indicates an incompatability with the receiver. Tracing continues, however, some trace data may have been lost. A value of terminating is a normal transient state which occurs if a Stop command is received before the local VC has been created.
