I am studying SAS1.1 specifications.  
 I have some queries related to the SAS specifications
 -- For how much time shall state machine wait for some transmitted
  messages from transmitter, for example COMSAS transmitted?
 --Will receiver be able to detect the "completion" of detected OOB signal
  without detecting negation time(6.5)?
 --"Address frames shall not be terminated early". What's meant by early
 -- On page 27 (4.1.2) it is stated that SAS phy may use different 
 roles(initiator or target)  in different connections. On page 119(6.6.5) it 
 is stated that SAS target phys should not originate a new phy reset sequence 
 after their first attempt. How is target/initiator device exepected to 
behave  if its first attemt of phy reset sequence fails?
 Thanks in advance

With Warm Regards
