I quoted the paragraph that is the response to a failure in the request to send the DATA frame not the failure of the source to receive the DATA frame. That information is in Table 141 ? Messages sent to the ST_IFR state machine in the last two rows. So the message sent to the ST_IFR state machine is either Transmission Complete (Data-Out Failed, NAK Received) or Transmission Complete (Data-Out Failed, ACK/ NAK Timeout).

Could anybody help me for solving some doubts in Transport layer. I have few doubts regarding implementation of Transport layer state machines. I am referring to SAS2r03a 22 April 2006. Following are queries : 1.How does ST_ITS state machine notify ST_IFR state machine that NAK or ACK/NAK timeout have occurred for DATA frame corresponding to first enable burst.Is it going to use same message as it is using for the DATA frame corresponding to XFER_RDY frame? if yes, then message( Transmission complete(Data-out failed,NAK received)corresponding to NAK & message Transmission complete(Data-out failed,ACK/NAK Timeout)) ST_ITS uses to notify ST_IFR is given but How ST_IFR will handle these message or notify Application layer about data sending failure seems to be missing.
