I've been looking for the Panasonic ringer box for a 96 port DBS system so that my analog phones will ring. I can't find one at a reasonable cost....which got me to thinking. All the ringer box is simply a ring generator....so would it be possible to canabalize a Norstar ATA or a WEco 1A2 power supply and somehow get the ring generators from these devices to work on my DBS system?
