Well, I no longer have access to access to the SNA FAPs and can't find
the equivalent APPN architecture definition so I don't know if there is 
any difference between the PUCP in a node type 2 and the PUCP in a
node type 2.1.  But in looking at a display of a "PU_T2.1" I see 
characteristics of the linkstation and maybe the node, but nothing 
I would associate with the PU.

I think you might still be safe saying there is no such thing as a 
PU_T2.1.  :-)
