It depends on who the ILEC is and whether you're interconnected via your own SS7 trunks or not. In BellSouth territory you can order a multi-tandem super group to cover all the tandems in the LATA. You just pay a per-MOU charge to have them deliver the traffic to the other tandems. Its not worth it if you have to send a lot of traffic though. In the Verizon and other AT&T areas they make you order trunks to every tandem so you don't have a choice. In the old CenturyLink areas you could send traffic through your Access Tandem group as long as you had SPOP in your ICA. Your other option is to "lease your PSTN connection" through a third party provider like Inteliquent, Peerless, or Wide Voice that have SS7 trunks connected to every tandem in that LATA. It eliminates your need for SS7 links but you do pay a per MOU for every call.

When your service area is taken care of by one tandem in the LATA, do you connect to the other tandems in your LATA?
Currently I just send anything that's not on my single tandem (or my direct connections) to my interLATA termination. How common is that? It's pricey to build out to the other tandem.
