I'm looking to install a modem bank to provide net access for faculty and staff when at home. Anyone out there in tech land have any exerience with this?

I've already got RRAS setup and working, the phone company is gonna put in some digital lines for us, so the only thing left is the modem bank. I'm just looking for some info on brands, models, what sucks, what doesn't. I've never looked into buying one before, so I'm kinda lost.

We only need about 5 modems initially. After a short break-in period we'll prbably double that number, so it needs to be expandable. I don't see us every needing more than 20 modems.

Any help would be greatly appreciated.
