Apparently, Frontier just use TNS and Syniverse and don't have their own infrastructure.

Has anyone in here done this with Frontier? They're our ILEC and tandem operator. 

Is that aspect of Frontier reliable? 

Is that aspect of Frontier any less money than what I'd be paying now?

Can you order SS7 links directly to the tandem (f-links?). Should just be a internal cross connect in the building. Then you build ISUP routes for the tandem point code over the direct links with backups over your current A- links

There are pros and cons to everything. It sounds like in your case you 
may just want to keep your ISUP trunks and SS7 links, but maybe look at 
another provider for SS7. Syniverse is also an option but I'm not sure 
if their service has gone downhill like TNS' apparently has.
