That doesn't make any sense. Bandwidth in what respect? Size of trunk groups in access tandem links? Those places are in low-populated areas; it is logical to expect their facilities to be less dense there than in metro markets. That's not really "bandwidth" in the conventional sense, either way.
I'm working on a project that will require completion of up to 1m calls/hour into particular areas, so I'm learning a lot about the details of inter-carrier capacity and bandwidth available for voice. A company like L3 has IP connectivity into most of the areas where it can terminate/originate calls, and the amount of that is based on expectations of call volume based on the type of area and population. Then there are the telephony trunks from the L3 IP gateways to the local carrier(s) which have a hard limit of concurrent calls.
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.
