you want an FXO channel bank, or at least a channel bank with 10 FXO channels, 
since you'll be wiring it up to the telco.

You want CPD (calling party disconnect, also know as far end disconnection, 
disconnect supervision, etc.).  On FXS it doesn't matter but on FXO it's a 
critical feature IMO.  Carrier Access ABI and ABII do not have this feature.  
CAC's Adit600 does.   I don't know about the others.
