No doubt about that, not sure why the Greg wants to do what he is asking
for, personally I would use 2 used Cisco routers with integrated T1 DSUs
and priority queuing for VoIP, assuming VoIP phones at the remote
location. That would be about $600 for qty 2 on ebay!

I just assumed Greg had a need for a T1 TDM interface on both ends.
