We have a facility roughly 1/4 mile away. We've tried line of sight 802.11b bridges but have continuous problems due to the amount of trees located between locations. Is there a way to use dry lines from the telephone company and connect two dsl modems between buildings? This would be cheaper than having them provision a T-1 to this location (not to mention the routers we would need). All of the users at this location are terminal services users so the bandwidth can be pretty small. We have a westell dsl modem laying around and I have a modem at home that I'm not using anymore. Do the modems have to be the same type?
