Thanks George for the reply.
You are correct that Train-SNW has been replaced by Train_Rx-SNW in revision
4 of SPL-3.
But two issues still remain:
1.	  MTT to be replaced by MRTT which you have already acknowledged.
2.	 Colors used in Figure 80 for First Train_Rx-SNW and Second
Train_Rx-SNW are those of ALIGN(0) and ALIGN (1)
Instead of TRAIN pattern and TRAIN_DONE pattern

Pooja,
You need to look at the current version of SPL-3 which is revision 4 as some
of your comments have already been fixed. However, MTT is still not correct
in revision 4. I will correct that in the next revision.
Bye for now,

Hi,
Figure 79 - SAS speed negotiation sequence - phy reset problem in
Train_Rx-SNW of SPL-3 (Revision 02, 16 January 2013)
Shows SAS speed negotiation sequence for a case where there is a problem in
Train_Rx-SNW .
Here, I see two issues in the figure as mentioned below:
1.	 As per new spec, in SNW-3 we can have Train_Rx-SNW and Train_Tx-SNW.
There is nothing like Train-SNW and
Figure title also mentions it as : Train_Rx-SNW. So, I think this needs a
correction
2.	 In SNW-3 after Phy capabilities are exchanged, after RCDT, MTT is
written.
There is no such timer as MTT defined in spec. For Train_Rx-SNW, it should be
MRTT.
Similar corrections are required in Figure 80 on Page 192 for: Train-SNW and
MTT.
In addition, in Figure 80, colors mentioned at the bottom and used in the
figure are not correct for TRAIN pattern and TRAIN_DONE pattern.
Please share your opinion on this.
Regards,
Pooja
