I don't know of any CSU/DSU cards, so you pretty much can't replace
that. Are you going to do 56K or fractional T1? I just say that because
I know you can get a 56K only CSU/DSU for considerably cheeper than
$1000. We sell Motorola 56K CSU/DSU for $240. I guess a T1 is going
to cost $1000 or so. I'm not a sales guy, so I don't know exactly.

Are you going dedicated line or Frame Relay? Frame is cheeper.

Then you'd need a synchronous serial port, and software (Frame or
dedicated) to run it. I don't think there are any Frame Relay drivers
for FreeBSD.
