If you're connecting to a carrier's SS7 network, I'm pretty sure you
need to be using carrier-lab-approved hardware -- and very probably
software -- to do it.

Things may have changed since, oh, 5 or 6 years ago when I last paid
any close attention to SS7, but last I heard, the ingress ports to that
network are not filtered enough for them to let just anyone hook up to

That said, those links *used* to be V.35 off the terminal equipment; I
don't know whether they're using T-spans for them now, but even if they
are, I suspect you might need custom *drivers*, not just custom
app-level software.  But IANASS7E.
