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You are correct that Train-SNW has been replaced by Train_Rx-SNW in revision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

There is nothing like Train-SNW and
