I don't have experience of the FXO card but to "start" a ground start trunk you must have a good ground (< 2ohms) Connecting up a "grounding strap" around a copper cold water pipe works well.

I am having a problem using the Adtran 750 FXO quad card with a Groundstart
trunk line. I am able to receive calls on the trunk line, however dialing
out is not working. The Adtran does not seem to be doing the signaling. Has
anyone used the 750 FXO card in Groundstart mode? Any special configuration
issues that I should be aware of?
