Channel banks usually end up with d/a conversions, which is what you must avoid in order to support 56K modems. Various router vendors have several products. I work at Cisco, the AS5200 and AS5300 both support 56K modems. Also, be aware that there are two competing standards at the moment, X2 pushed by USR/3Com (they're the same company now) and Kflex, pushed by Rockwell, et al. Cisco gear supports Kflex at the moment, though I believe just about every vendor out there stated they will support whatever standard becomes, well, standard early next year. -jav (not a Cisco spokesperson)
