Thanks for the SDLC start up info.  

What I think you  have described is two scenerios how a CU attached DLSw 
activates  SDLC stations. These being 1) CU attached DLSw SNRMing a CU 
based on locally configured info to do so and 2) CU attached DLSw SNRMing 
a CU because it received a CURFRAME from a partner DLSw. The assumption 
here is that the host attached DLSw is connected using Token-Ring to a 
mainframe. 

My original question relates to how station activation occurs (will 
occur?)  in an SLDC end to end environment. Specifically in the area of  
leased line attached DLSw (to hosts). Given that this scenerio does nor 
include XIDs, how would  the circuit be established?
 
Returning to the start up info you supplied, I have the following 
questions:

1) How is XIDing done at the CU attached DLSw in the following 
configurations?
a) Direct connect or leased line attached CU 
b) Dial up CU 

Finally, which DLSw is gray and which one is blue?
