Lyndon,

Here is the just of the thread.  I agree with your
earlier note that this should be addressed after the
other issues are resolved.

People seem to object to the SUA statement that RC
implies SS7 entity (point code), when it is just a
statement of fact, and also object to the SUA statement
that RC is exchanged between SGP and ASP, when that
is just another statement of fact.

These statements of fact add clarification to the
role of RC in both M3UA and SUA.  Just clarifications
that some will be rather testy about until the main
issues are resolved.
