hi the Msc is the main switch witch swtchs speesh calls only but if thers is any other kind of data (packet switching for exemple)we need to pass from other equipements thus we go via the MGW of the packet switching
we use the media gateway to go for un other network like pstn…etc.
i hope i answered your question
