I have had two option elevens have the same problem. The problem is, the DCH goes into ENLB AEST state. And all the channels on the pri goes into a MBSY state. If I try to disable the dch, I get this DCH1019 message, telling me the card is hardware disabled. All lights are green, and I cannot disable it. I have to physically pull the card out, disable the span, put the card back in and enable it. Anybody have this problem?
