Walter, "Frogging" goes back to "leap-frogging" cable pairs to make a line work. (White-Blue pair bad, cut to Violet-Slate from pole 1 to pole 2, cut back to White-Blue)
Now then,
, Al, the suggestions here are all good. Do you have a test jack to test the output of the card at the backboard? Does it work there? Make a test jumper to plug into the station card with only this port wired out to the jack. Does it work? By then a spare card should be available, try it. Until you know if the problem is software or hardware you are not going to be able to follow this through. By testing the hardware you are left with software if the sets do not ring. That is where the ring group, et al, comes in. Go to a correctly ringing set, do a "Copy" and see if it is ringing now.
Good luck.
