Does that include access tandem links? I was under the impression that
when it came to termination in podunk areas where a company like Level3
would have no interest in colonising end-offices, they just acted like a
normal IXC and threw stuff into the tandem. And that the only way to do
that remains SS7/TDM unless riding some sort of intermediary. Am I wrong?
