If T1/E1 speed is enough, there are cards working with FreeBSD. If the
CSU/DSU is on the card, I think you don't need extra equip and you have
a symmetrical line. Should be OK for some miles with ordinary field
telephone cable. You configure these cards almost like normal network
cards if you run IP over them.
