I have a customer that has a Legend 6.0 with a Paradyne 3150 to a DS1 card. The Paradyne has a fail light on and the yellow light is on the ds1 card. The buttons on the paradyne do not do anything and restarting it has no effect. In the past I was able to restart it to clear any errors. I Know nothing of this unit at all. There were only a few in this area to begin with and they have all been replaced except this one. Any help is appreciated.
