Have you asked for a full T1 but with just 10-14 DID/DOD trunks? We can not get fractional T1 here but on a full T1 we can add anywhere from 1 - 24 trunks. So we pay one amount per month for the T1 and on top of that we pay another amount times the number of trunks we have. I know this didn't exactly address your questions. For your primary question I believe that your would need different type of channels in a channel bank than FXOs. DPTs (Dial pulse) terminating come to mind, but that may be wrong.
