Let me give you an analogy as to what you've described. I take a little
gizmo that splits my telephone outlet into two outlets (I use one of these
for my answering machine and telephone). I can plug two telephones into the
gizmo, but can they call each other? Without telephone service, no. But I
have my own bus where I can connect multiple telephony devices...
