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?
