We have a G3siV11 switch and want to add a Brooktrout Analog Card TR1034 +P4-4L to it for faxing. I am new to connecting a Brooktrout fax card to the Definity switch. Can I use analog lines from a TN793 board? I have read from Brooktrouts site that the Analog lines need to be loop-start and have no power. The Brooktrout card supplies the power. Any help would be appreciated.
