I have a Livingston PM2i connecting to a tc chassis. I can connect 1 BRI to the Total Control. When I try to connect a second BRI it authenticates then hangs up the second BRI. Any hints on how to keep the second BRI from hanging up? I am pretty sure everything is ok the the PM2i. Don't know why the 3com is not keeping the other BRI up.
