The SG is responsible for transport conversion.  See the work of SIGTRAN on
replacement of the SS7 stack by TCP or SCTP plus an adaptive layer.
However, the SG doesn't touch the application-layer protocols (e.g. ISUP).

It just seemed to me that the function being described in the draft
(converting ISUP signaling to SIP signaling) was an SG function as opposed
to an MGC function.
