5000-00 works, has 2 digital cards in it, 5002-01 has one more digital card in it, but does this take a special cable to connect the two, because that doesn't seem to be in the pile, and a straight cable doesn't seem to do the job. (the XTSc-IP ate its power supply, trying to hook up 4 more phones and 4 ports of voicemail and deal with the original unit next week.)
