The answer is yes.  QLLC is a mapping of SDLC onto X.25 connections, 
with the Q-bit being used to differentiate I-Frames and S-Frames.  QLLC 
uses one X.25 session per logical SNA link (links are point-to-point  
between logically adjacent nodes).

So architecturally you can have SNA traffic concurrent with other X.25 
users, but your access point has to support it.

By implementing QLLC on my IBM beastie, can I run both SNA and OSI 
protocols over the same X.25 link?  Have been told that this would
eliminate the need for a separate connection for each.  True?
