Re: M2UA terminology

IULIAN,

The SS7 network side of an M2UA SG is simply SS7
signalling links.  How the signalling links are
interpreted at the MGC depepends on how there are
configured for use by the MTP stack there.

M2UA simply provides, if you will, "remote" access to
the SS7 signalling link termination at the SG.

So, from the SS7 network perpective, your first diagram
is no different than, say:

        [SEP]------------[SEP]
             \          /
              \--[STP]-/ 

The SEP just happens to be functionally decomposed into
MGC and SG.

Hope that helps.
